I've got several JavaScript files that load along with many of my pages, costing valuable tens of kilobytes of data download. One of these is a version of jquery.min.js which although minified, is still 25kb or so. My issue is that a huge chunk of mobile phones don't support JavaScript so the downloading of this and other JS files is a waste of data. Is there anyway to lazy load the JQuery file by adding a <script> tag in the page that calls the JS file and would obviously only execute if a browser supports JavaScript, which would only then make sense to download it?

When an anchor tag is clicked, "anotherDiv" is made visible. Using jQuery, I want to be able to fetch the description within each li onClick of the anchor tag and insert it into the "anotherDiv" area which is also visible onClick of an anchor tag. The description text is initially set to display none. <style> .desc{ display:none; } #anotherDiv{ display: none; } </style> <li style="overflow: hidden; float: none; width: 158px; height: 125px;"> <a onClick="return addPlayer(952541791001, 661361792001, 600, 320)" id="no8" class="video-pop"> <img width="132" height="75" alt="" src="image.jpg"> </a> <div class="label">The label goes here......</div> <div class="desc">The descripti...

I'm developing a site and the client has requested we use the supersized plugin to display a gallery of images - which is fine, HOWEVER the have requested that the background image scrolls with the site rather than being fixed to the browser window. Something like this - http://www.surfcampinportugal.com/ . I've tried amending my CSS (changing position: fixed to absolute) but nothing seems to achieve this effect. Site is on my local server at the moment but I'm using supersized 3.2 with a fade transition - http://buildinternet.com/project/supersized/slideshow/3.2/demo.html Any pointers/ideas would be VERY welcome. Thanks

I am trying to create a backbone.js model with dynamic keys but can't seem to get it done right. Here's my model: window.MyModel = Backbone.Model.extend({ myDynamicVar : "country", urlRoot: "api/myModel", defaults: { "id": null, this.myDynamicVar : "USA", "country": { "route":"test/test/test", "class":".usa2", "txt":"USA 2" }, "region": "California", "year": "", "description": "", "picture": "" } }); Here I am trying to have myDynamicVar replaced by its content in my model. Any thought how I could get this done? Thanks in advance, Jimmy

Edit: After following a few tutorials I am stuck here I am new to jquery but have some experience with Coldfusion. I have been desperate for an easy tutorial that shows how jQuery/AJAX pulls a query from a ColdFusion9 CFC and displays it on the HTML calling page. I tried following this ben_tutorial but it is too complex for me. There is also a another tutorial , but I do not want to install a plugin. Where should I be looking? I am googling "jquery ajax coldfusion"

I am trying to execute a simple bit of jQuery or JavaScript once logged in to my Facebook account. The end goal at this moment is to click on my custom feed once the element is visible, rather than having it default to the entire Facebook friend feed. On trying to code this using my Developer's Console in Chrome no JavaScript/jQuery seems to work at all. Even just a simple $('div'); returns null . Is it possible to run code on Facebook's page? What are they doing differently? I guess the end goal would be to click a div if the .val('give a waffle'); but just understanding why it has not worked until now would also be interesting. Any hints, tips or suggestions are more than welcome.

I have the following: <input id="slider-min" type="range" min="0" max="55" value="0" step="5" onchange="sliderMinUpdate(this.value)">, <div id="min_input">0</div> <input id="slider-day" type="range" min="0" max="10" value="0" step="0.5" onchange="sliderDayUpdate(this.value)"> function sliderDayUpdate(value){ $('#slider-min').val(0); } function sliderMinUpdate(value){ $('#min_input').text(value); } When I focus in slider-min using keyboard and select keypad right or left it updates values in min_input correctly. When I change slider-day it fires onChange and updates the value from slider-min to 0 and I can see it working in my page (the slider returns to 0). The problem occurs when I select the first increment of slider-min , in this case 5. When the onChange from slider-day is cal...

So, I have a form on page 'A' which lets users type in the name of a band and see album covers and prices, courtesy of the Amazon API. <%= form_tag(amazon_path, :method => 'get') do %> <h3> Search for Albums </h3> <%= label_tag(:amazon_search_form, "by Band/Artist:") %> <%= text_field_tag(:amazon_search_form) %> <%= submit_tag("Search") %> <% end %> Users can also see all bands they are following on their profile page. From their profile page, they are able to select a band 'b' (perhaps by clicking on the band's img). After that, if they click on the link to go to page 'A', I would like the form to be automatically submitted with band 'b's name so that the user won't have to type in the name of band 'b' to see the albums for band 'b'. I can't tell if jQuery's .submit function can pass a parameter of the band's name to the form when ...

(By the way, a quick experiment indicates that the answer is "yes", but it might be "it doesn't work in every browser".) I am using a validator plugin that binds something to the submit event of a form. But I want to perform additional validation. It would seem that I can simply bind my additional validation to the submit event. HOWEVER, I worry that that might not work on every browser. Should I expect this to work or will I need to write more complex code?

Last night someone on here really helped me out a lot with my first validation from scratch, i brought it alot further since last night. This is the first time I'm touching JQuery, I apologize for my crumby coding. Here's what I have that works fine and dandy for the validation UP until the last else statement: //VALIDATE FIRST REGISTER PAGE! $('#submit1').live('click', function() { check_value1(); }); function check_value1(){ var firstname = $('#firstname').val(); var lastname = $('#lastname').val(); var email = $('#email').val(); var password = $('#password').val(); var username = $('#username').val(); if(firstname =='' || firstname.length <2) $('#fnameError').fadeIn().fadeOut(5000); else if(lastname =='' || lastname.length <2) $('#lnameError').fadeIn().fadeOut(5000); else if(email =='' || email.length <5) $('#emailError').fadeIn().fadeOut(5000); else if(pass...

I want to count all img elements and take attribute (alt) of FIRST of it. My try: $('img').each(function(index) { /* need count and take forst */ if(index=0){ var objid = $(this).attr('alt'); } }); Can you help me with this?

I want to delete the classes that end with 'blue' from the class attribute on all tags sample html <p class="text_blue happy">this is blue text</p> <p class="text_red nothappy">this is red text</p> <img class="img_blue nothappy" /> This will give me all the elements with classes that end with 'blue' $('[class$=blue]'); how do I pop these matched classnames off of the class attribute?

I'm putting together this basic script for a site: http://jsfiddle.net/mcgarriers/rVPnu/2/ It works great when I select the various numbers (it shows the relevant divs) but when I go back to click "Select" it still displays the <div> s. I'd like it if the user clicks "Select" that mySpecialElements is hidden again . Can someone show me how to achieve this? Many thanks for any pointers.

I put jquery.validate.js in my public/javascript folder and I called <%= javascript_include_tag 'jquery.validate' %> in the header but I get this in the chrome debugger: Uncaught TypeError: Object [object Object] has no method 'validate' I can see jquery.validate.js?1317943298 under javascripts/ in the chrome debugger. On the other hand, when I add this right before I call validate(), <script type="text/javascript" src="http://jzaefferer.github.com/jquery-validation/jquery.validate.js"></script> it works. I see jquery.validate.js under jquery-validation/ as well as jquery.validate.js?1317943298 under javascripts/ in the chrome debugger. Both files are identical. What's going on here?

This may be obvious, but I can't find the answer anywhere after hours of searching. I just need the syntax to adjust the initial opacity of a Fancybox gallery. Not the overlay or anything like that - just the initial thumbnail opacity. I've tried changing every setting I can find in the fancybox js and tried overriding opacity in the css, but no matter what I do, they stay the same. Hmmm. I have no weird code, just a simple $("a.gallery").fancybox() call on a thumbnail image. I just want the opacity to be a bit more opaque!

My company is engaging with a multivariate testing vendor (I can't disclose which one just yet), and I am being asked to integrate their system into our flagship B2C commerce site. Usually, the word "integrate" is a heavy-duty term. However, here it means to add a <script> tag on several views, and then be out of the loop from that point forward. The mulitvariate experiments will be set up by our marketing department (and/or the vendor). Our development team will not be involved in that, and may not even be aware when it's happening. Essentially, I am being told to deliberately add a JavaScript-injection attack vector to our flagship application... and hope for the best. My concerns are not so much with malicious code as they are with inadvertent screw-ups. Our CSS and basic page layout is a mess already, and I anticipate catiching the heat when someone else's multivariate experiment blows up the home page look-n-feel, etc. Much more importantly, ther...

{ id: 1533, story_type_id: 1, content_id: 470, created_at: Sun, 05 Feb 2012 07:02:43 GMT, updated_at: Sun, 05 Feb 2012 07:02:43 GMT, type_name: 'post' } I have a JSON object with the "datetime" field like above. It's perfect. But when I stringify it (I want to store it in cache), I get this format: "created_at":"2012-02-05T07:02:43.000Z" This causes problems, because when I want to JSON.parse this, suddenly it's no longer datetime format and it's incompatible with my other format. What can I do to solve this problem? I have 'created_at' littered everywhere throughout my application. I don't want to manually change each one.

I am a new PHP learner. I need a status box which just like twitter status box. I have tried many websites and i can not find the exact solution. What i exactly need is 1. Status box like twitter, when typing on the box it will increase its size automatically 2.If there is URL in the status, it should automatically highlight URL like twitter 3.After 500 characters user should not allowed to type in. I don't want to use any API. I think the code might be combination of HTML,ajax and javascript. Please someone help me. I am new in this area. So if it is possible give a little explanation of your code. I found a bit similar question in this website but the answer is not given there.

Actually I want to put a div tag on this center point. Is there any equation solving involved in this process?
