jquery select iframe children

By User


I am using the editArea library and jquery to do what i need...



http://www.cdolivet.com/index.php?page=editArea&sess=2b8243f679e0d472397bfa959e1d3841



so in my html there is an iframe tag that editArea uses what i need is to access something like so with jquery 





$('iframe textarea').keydown(function (e){

   number = 17; //any number really :)

    if(e.which == number){

        //do something...

        alert('Done...');

    }

});


I tried the above but it looks like it is not detecting that key. but it works if selector was $(document) therefore the rest of the function works it's just it's not picking up the iframes textarea keydown



any ideas? Thanks

    $("iframe").contents().find("textarea").keydown(...)

    You need search within the inner document of the iframe, in order to get the textarea element:

    var textarea = $('textarea', $('iframe').get(0).contentWindow.document);
    textarea.keydown(function (e){
    var number = 17;
    var code = (e.keyCode ? e.keyCode : e.which);

    if(code == number){
    //do something...
    alert('Done...');
    }
    });

    You need to access the iframes contentWindow.document, not the iframe itself.

    You should be doing



    iframeDoc = document.getElementById('resultsFrame').contentWindow;
    // result frame is id of iframe
    $(iframeDoc).keydown(function(e))
    {
    // your functionality here
    }

    You can travel any level, The above answers are correct. I did as below

    var iframeMain = $("#iframe0").contents().find('#iframeMain');
    var detailsForm = $(iframeMain).contents().find('#detailsform');


    for accessing parents you can use

    window.parent.parent. // upto any level

Why is this Javascript much *slower* than its jQuery equivalent?

By User
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...

Is it possible to have IF statement in an Echo statement in PHP

By User
Thanks in advance. I did look at the other questions/answers that were similar and didn't find exactly what I was looking for. I'm trying to do this, am I on the right path? echo " <div id='tabs-".$match."'> <textarea id='".$match."' name='".$match."'>". if ($COLUMN_NAME === $match) { echo $FIELD_WITH_COLUMN_NAME; } else { } ."</textarea> <script type='text/javascript'> CKEDITOR.replace( '".$match."' ); </script> </div>"; I am getting the following error message in the browser: Parse error: syntax error, unexpected T_IF Please let me know if this is the right way to go about nesting an IF statement inside an echo. Thank you.
