I'm using asual jquery address plugin for page navigation. But I have a little problem. When I'm inserting mypage.html#first_paragraph address plugin recognize this as new page, not as "goto operation". And I just want this link to go to that place of my page. How can I do this? For example: http://developer.android.com/reference/android/widget/ListView.html#addFooterView(android.view.View ) see, when you click on this link its automatically goes to that place of page (with the addFooterView method) When I'm trying to release this using jquery address plugin, this (<a href="ListView.html#addFooterView(android.view.View)">ListView</a>) link (it opens new page) is recognizing as link (not "go to this part of page" operation)

I am using the slimScroll plugin for jQuery by Piotr Rochala Which is a great plugin for nice scrollbars on most browsers but I am stuck because I am using it for a chat box and whenever the user appends new text to the boxit does scroll using the .scrollTop() method however the plugin's scrollbar doesnt scroll with it and when the user wants to look though the chat history it will start scrolling from near the top. I have made a quick demo of my situation http://jsfiddle.net/DY9CT/2/ Does anyone know how to solve this problem?

I know some selectors are faster than others, and of course our own methods can be faster or slower. Is there any software/app that analyzes cpu usage or even is able to compare/benchmark among versions?

I'm trying to return a JSON encoded array from a PHP page via ajax. here's my code from the calling page $('#test_load').click(function(){ $.ajax({ type:"POST", url:'/actions/admin_load.php', dataType: 'json', asynch:false, data:"action=4", success: function(json) { alert("we're back"); alert(json.a); } }); }); here's my php code //return json array case "4" : $str2 = "HELLO"; $arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5); $str = json_encode($arr); echo $str; break; I keep getting "json is null". Any suggestions would be much appreciated

Is there a way of catching the modification of a specific data attribute (i.e. 'data-whatever')? My first thought was to go with DOM mutation observer but was wondering if there's any 'easier' way through jQuery?

I met some jquery menu mouseenter problem.

Sorry for the newbie question, but I can't seem to work around this issue just yet. I have a website with dynamic content all over. When you go to the page of an article, it pulls the content from the database etc. If the user is logged in and is an admin on of the website, I am displaying an "Edit article" link in the top right corner. The only problem is the position of that "Edit article" div . On different screen resolutions, it moves around, as the it's set with a position:absolute , top:x px , left:y px . I am open to any suggestion (Javascript, jQuery most welcome, easy peasy CSS would be best if possible).

from http://api.jquery.com/animate/ : queue: A Boolean indicating whether to place the animation in the effects queue. If false, the animation will begin immediately. As of jQuery 1.7, the queue option can also accept a string, in which case the animation is added to the queue represented by that string. I want that the animations added to an object should be start when the last animation ends. From the jquery doc it seems to me that, in order to achieve this, the animation must added to a queue. if I pass {queue: true} the animation is added to the general queue, while in jQuery 1.7 I can pass {queue: "queue_foo"} to add the animation to a certain queue. I wrote this in my code, but the animation is not executed. showedSlide.animate({ left: -showedSlide.outerWidth() }, {queue: "left"});

I Need away to show two per page, and have a pagination at the bottom of the page. Here is how I am currently doing it. As you can see we dont do any pagination at the moment.

I'm using some one else's plugin and I see that it has configurations available, ie. 'tabs:true'(see below). When I look at the plugin file it's just one long line that includes some of these settings separated by pipes '|' like, |scrollspeed|scrolleasing|panelfxfirst|panelbtnshover|verticalslide| <- What are these called so I can google how to use them? I've tried adding panelbtnshover=true, and there was no hover effect. My guess is need to read the two jquery books I bought some more. <script type="text/javascript"> $(window).load(function(){ //$(window).load() must be used instead of $(document).ready() because of Webkit compatibility // Tabs > Standard $(".tabs-standard").sliderkit({ auto:false, tabs:true, //mousewheel:true, circular:true, panelbtnshover:true, panelf

Just cant figure it out. I have a large object stored as a JSON file and I want to access it once and use it multiple times: var myjson = new Object(); $.getJSON("myJSON.js", function(json) { myjson = JSON.stringify(json); }); $('#console').append(myjson); This does nothing. It's a scope issue, I know. I just don't know how to do what I'm wanting. Must I do all my functions inside the $.getJSON call or is there a way to pass the object that I can use throughout runtime?

I have three grids each has a unique: pager, ID, and wrapper. These grids are hidden by default and show upon selection of a dropdown box. At page load, before anything is selected, jqgrid makes three ajax calls for its data, but after debugging it appears that each grid makes three calls, one for each of the grids on the page. I would like each grid to only request its data for its own grid. Typically the first grid times out and the other two work flawlessly. I believe that the first one may bog down the number of connections to the server causing it to timeout and then the others are then free to proceed because they are below the max number of connections. Any thoughts, ideas, or suggestion are greatly appreciated.

I am using the Galleriffic jQuery plugin for my photo gallery. The gallery images are loaded from a database in PHP. I want to be able to link to one photo in the gallery from another web page, with an URL query that passes the ID of that image. This image should then be selected and shown in the big preview (or slideshow container), instead of the first image which is the default. What I want to do is: mywebsite.com/pictures/?pid=12345 where 12345 is the ID of the image to be selected.

So, i see no reason why this isn't working but i am at a wall and frustrated. Why can't i call this.myself from within the wyr.message.close function? Maybe my understanding of this is scewed but i was sure this is referring to the object itself, not the function. this.myself is undefined Code: wyr.message = { myself: $('.message'), init: function() { if(this.myself.is(':visible')){ setTimeout(this.close, 5000); } }, close: function(){ this.myself.fadeOut(1200,function(){ this.myself.remove(); }); } }

The excerpt below is part of a .ajax() function I'm using to pull data from a database. The database is queried using PHP and the output sent back in JSON format. Only 1 row of data is returned by the function. success: function(data) { for(var key in data) { $("#formTable tr").find("td:eq(1)").text(data[key]); } } I have an HTML table on the page which is split into two columns. The left column has field labels, the right column is empty. I would like to cycle through my JSON reply for each key/value pair. I would like to insert the value into the right hand column table cell. The code should cycle through until all key/value pairs have been output onto the next table row, into the next right hand table cell. The code above selects the second column table cell but inserts the last JSON value into all cells instead of each value going into its' own table cell in the column.

I have a large script that is very synchronous. 1) it runs a function like this: var result = doSomethingSynchronous(myVar); if (result === 'something') { doSomethingElse(); } the doSomethingSynchronous function has a for loop that returns a value on a if statement: var i = 0; le = someVariable.length; for (; i < len; i++) { if (someVariable[i] === 'aString') { return true; } else { doSomethingElse(); } } Because the for loop and the processing can be intense, I've replaced the for loop with an iterative queue processing function that runs itself asynchronously using setTimeout after shifting one element from the array. Once it runs asynchronously of course it doesn't return the value and assigns it to the 'result' variable in the first snippet synchronously, and the if statement there always fails. My question is, is there a way to keep this part synchronous? Have the value be assigned to result before the script goes on to th

I have a Grid view where I have a hyper link button which displays ID, by clicking on it I make a Ajax call to the server and get the specific URL to navigate against of the ID.

How to get rid of it any idea??

I have the following (2) 'ScriptableMember' types in my Silverlight control: <ScriptableMember()> Public Property MType As MyCustomType <ScriptableMember()> Public Property Message As String The purpose here is obviously to allow exposure via the HTML bridge in Javascript. Calling the 'Message' property is trivial and works perfectly like below: var SLControl = document.getElementById("SilverlightControl"); SLControl.Content.MyRegisteredControl.Message = 'Hello'; However I am having trouble setting the values of an instance property by drilling down to its properties in JS. The code I would think should be as below: SLControl.Content.MyRegisteredControl.MType.Name = 'John'; Notice how I added in the 'MType' and then accessed one of its Public Properties named 'Name'. The MyCustomType class has all the appropriate 'ScriptableMember' atributes as required. However when that line above is ran I get the

I have a jsp page where if the user closes the page the popup box should appear asking whether he really wants to close the page. If he chooses to close the page then i need to redirect to another jsp page using ajax. How do i achieve the same. I have a sample code which asks the user when he clicks the close button but this message is getting popped up when refresh,submit or clear buttons or any other buttons are pressed. Can anyone sggest to modify the given code or any new functionality which achieves the same. sample.jsp <html> <head> <title>Refresh a page in jQuery</title> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> </head> <body> <h1>Stop a page from exit with jQuery</h1> <button id="reload">Refresh a Page in jQuery</button> <script type="text/javascript"> $('#reload').click(function() { location.reload(); }

I have an ordered array which looks like this:- [-0.0020057306590257895, 50, 0.09598853868194843, 50, 0.19398280802292264, 49.99999999999999, 0.2919770773638969, 50] What I would like to do is the following: Take each 'odd' entry and make it the 'key index in an object, which can be achieved by rounding the value and multiplying by 10 e.g. (Math.round(-0.0020057306590257895 * 10) should be index 0 and Math.round(0.09598853868194843 * 10) should be index 1 etc) Take the 'even' values and make them the corresponding values in the object. So... The above CSV file should return the following object:- { 0: 50, 1: 50, 2: 49.99999999999999, 3: 50 } Does anyone one know how I can parse this CSV to produce the required array using either jQuery or plain javascript?

But if I change this line to: calendar.d

Introduction Google chrome has a feature that allows you to create shortcuts to web pages and make them appear like traditional desktop applications. For example, a shortcut to twitter mobile might be C:\Users\<username>\AppData\Local\Google\Chrome\Application\chrome.exe --app=https://mobile.twitter.com/ The file icon for this app is stored in C:\Users\<username>\AppData\Local\Google\Chrome\User Data\Default\Web Applications\mobile.twitter.com\https_80 My Question It's been a while since I've used this feature and I seem to remember that you could add your own javascript files to the app folder which were included when the application was loaded. However, I cannot find any documentation that discusses this feature but I'm 99% certain it exists. Does anyone have any details if this feature is available and what files I need to create?

I'm developing a js to dig up Bible references on Portuguese web pages, and link them to a youversion.com url. This is one of those pages: http://www.adventistas.org.pt/Evangelismo/Web/Img/Downloads/Trimensario/2012/1t/online/licao7.htm This is the script: http://www.adventistas.org.pt/Evangelismo/Web/Img/Downloads/Trimensario/2012/1t/online/bibleref.js It pretty much works, but it acts kinda funny, and can't find out why. Sometimes it outputs empty links with correct bible references, and then outputs the real link, with a wrong reference. Eg: <a target="_blank" href="http://www.youversion.com/bible/verse/arc/gen/2/1-3" class="passagem"></a> <a target="_blank" href="http://www.youversion.com/bible/verse/arc/gen/2/1-3" class="passagem"></a> <a target="_blank" href="http://www.youversion.com/bible/verse/arc/gen/2/1-3" class="passagem"></a> <

Using jQuery, I know $.ajax() can be used to POST to a url but I can't use $.ajax() for my problem. I want the client to POST to a url and have the server redirect to a user to some url (PRG pattern) so therefore, it cannot use XHR requests. How can I get the client to POST to a url without creating a <form> ? Surely, there's got to be an easier solution than this. jQuery post request (not Ajax)

This problem has bothered me for a while and Im sure theres some sort of technicality which stops this from being possible, but is there a way to find which Javascript file is linked to a button? So when I press a submit button and it triggers a Javascript event, I need to find the code which is being triggered rather than trawling through every link in the head of the html trying to find "jQuery('submitBtn').click(..." Im using Firebug and sometimes Chrome's console.

trying to figure out how to write the following in CoffeeScript: var foo = new function() { var $this = this; $("#foo").click( this.clicked ); this.clicked = function() { $this.alert( $(this).text() ); }; this.alert = function(message) { alert(message); }; }; Unfortunately I can't figure out for the life of me how in CoffeeScript I access the class pointer, "this" is obviously not context aware and will often just point to the variable passed by the callee. So there's no way for me to write the above script in CoffeeScript. Any advice? I can't find anything useful in the documentation, you have the @ pointers but they also just use the "this" pointer from the current context, making it useless..

This is probably pretty easy, yet I am confused, so maybe I might still learn something more today. I am trying to do the following: var myObj = {}; myObj.src = {} myObj.src.A = ['1.png','2.png','3.png']; myObj.A = new Image(); myObj.A.src = this.src.A[0]; This will result in an Uncaught TypeError: Cannot read property 'A' of undefined error. When I use myObj.src.A[0] instead of this it is working fine. What would be the correct way to use this in this context?

Im attempting to utilize some custom script and css files within an asp page.

I am in the process of migrating my Drupal 6 site to Drupal 7. As a result i am facing some issues with the code. The calling of javascript laced with jquery etc is different in Drupal 7 is what i have read. This is the image of the page i had in Drupal 6. On change of the dropdown box, the table above it gets populated with projects belonging to that status. This works fine in Drupal 6. But in Drupal 7 i see this javascript error. This is the form element for the Dropdown in my php file. <? php $form['status_list'] = array( '#type' => 'select', '#title' => t('Freeway Project Statuses'), '#options' => array( 0 => t('-Select Status-'), 1 => t('Draft'), 2 => t('NotSpecified'), 3 => t('Quote'), 4 => t('Forecasted'), 5 => t('InEvaluation'), 6 => t('Cancelled'), 7 => t('Booked'), 8 => t('InProduction'), 9 =&g

I know that JSLint is only a guide and you should take what it says with a grain of salt, however, I'm curious how I can even resolve this warning without rewriting the entire function. Here is the function of interest: function randomString(length) { var chars = 'ABCDEFGHIJKLMNOPQRSTUVWXTZabcdefghiklmnopqrstuvwxyz'.split(''), str = '', i; if (!length) { length = randomNumber(chars.length); } for (i = 0; i < length; i++) { str += chars[randomNumber(chars.length)]; } return str; } JS Lint tells me "JS Lint: Use the array literal notation []." and it is pointing to the line with string.split() . How can I satisfy JSLint without having to re-write the entire function? Is it even possible? I am aware that there are other methods to generate random strings; I'm interested in how to resolve the JSLint warning using this method.

I'd like to convert my library in Javascript to C#. While doing research, it seems that it'll be easier to compiling the Javascript directly to a .NET executable instead of converting the code to C#. I've found IronJS but I found way to compile to .NET exe or dll to unassemble later.

Basically I want to be able to grab the ending of an url, and convert it into a string to be used somewhere. Currently I'm doing this (which is less than optimal): // grab the path, replace all the forward slashes with spaces local_path = location.pathname.toString().replace(/\//g,' '); // strip empty spaces from beginning / end of string local_path.replace(/^\s+|\s+$/g,"")); But I think there is probably a better way. Help? Edit: Could I confidently get rid of the .toString method there?

The following snippet is from an opensource poker client written in JQuery. It displays a poker table that has been previously spawned by the poker server. The table is displayed within a div on the page after the page is loaded. // // featured table // jpoker.plugins.featuredTable = function(url, options) { var opts = $.extend({}, jpoker.plugins.featuredTable.defaults, options); var server = jpoker.url2server({ url: url }); server.registerUpdate(function(server, what, packet) { if (packet && packet.type == 'PacketPokerTableList') { if (packet.packets.length === 0) { var updated = function(server, what, packet) { if(packet && packet.type == 'PacketPokerTableList') { var found = null; for(var i = packet.packets.length - 1; i >= 0 ; i--) { var subpacket = packet.packets[i]; if(opts.compare(found, subpacket) >= 0) { found = subpacket;

What version of the iPhone first supported JavaScript?

Yes, I'm aware that this question has already been post, but ... I'm looking for a way to check if the Client has Javascript Enabled. Here is my idea : At every loading page, PHP initialize $_SESSION['is_js'] to 0 . Then, I wish AJAX to ( via launching a script php ? ) try to set $_SESSION['is_js'] to 1 . If JS is enabled, AJAX will succeed, if not, the value remains 0. I can't use jQuery or others libraries... I have to write this in pure AJAX ( I mean not using framework or librairies ), and I have no idea how to do this. Edit : I can't use cookie. I don't want to use <noscript> .

So I tried to do something like this - $('#price').val(price); price is 300, and it shows good on browser, in input field, but when I want to take it out and mail it with PHP, in $_POST['price'] it doesn't show up, How can I insert something in inputs value with JavaScript, so I can mail it? It seems this is not an insertion in value, but just a feature to display something, correct?
