jquery select iframe children

Question

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

Answer 1

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

Answer 2

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...');
    }
});

Answer 3

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

Answer 5

You should be doing

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