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

boys i know that it doesn't work but i only put that as a demostration ... but none of the answers are doing it for me. I wonder if editArea has stopped the propagation or something of that kind? — Val, May 23 '10 at 20:47
Is the iframe pointing to the same domain as the parent page? — Spencer Ruport, May 23 '10 at 21:02

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

Should note that .contents() only works if you are on the same domain – jake_feyereisen Dec 09 '14 at 16:19

What if one isn't on the same domain? Can one still at least use an element clicked in that iframe to trigger something in the parent window? – cbmtrx Mar 19 '15 at 15:37
Another syntax: $("textarea", $("iframe").contents()).keydown(...) – pholpar Jul 27 '18 at 13:04
Also `.contents()` does not work if you're loading static html files on the browser. – h-rai Jan 13 '21 at 00:45

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.

This worked like a charm. Example: use `document.querySelector('#test_frame').contentWindow.document` instead of just `document`. See [*HTMLIFrameElement.contentWindow - MDN web docs*](https://developer.mozilla.org/en-US/docs/Web/API/HTMLIFrameElement/contentWindow) for the detail. – ynn Mar 25 '20 at 07:54

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

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

You should be doing


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

Below code helped me.

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

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

});
