jquery select iframe children

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; //a开发者_JAVA技巧ny 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 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 

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
}

If all else fails, I ended up getting the above to work by wrapping in this function:

$(window).blur(function () {
  // genius code here
}

Below code helped me.

$(document).ready(function(){
var iFrameDOM = $("iframe#frameID").contents();

iFrameDOM.find(".page").css("background-color", "#fff");

});
