How to access frame (not iframe) contents from jQuery
I have 2 frames in one page like this (home.html)
<frameset rows="50%, 50%">
<frame id="treeContent" src="treeContent.html" />
<frame id="treeStatus" src="treeStatus.html" />
</frameset>
and then in one frame (treeStatus.html) I have something like
<body style="margin: 0px">
<div id="statusText">Status bar for Tree</div>
</body>
I want from the top window to manipulate the div located in the child frame via jquery (e.g show and hide).
I have seen several questions like this and they suggest the following
$(document).ready(function(){
$('#treeStatus').contents().find("#statusText").hide();
});
I do not know if this works with iframes but in my case where I have simple frames it does not seem to work. The code is placed inside home.html
Here is some output from firebug console
>>> $('#treeStatus')
[frame#treeStatus]
>>> $('#treeStatus').contents()
[]
>>> $('#treeStatus').children()
[]
So how do I access frame elements from the top frame? Am I missing something here?
Answer
After combining both answers here, the correct way is
$('#statusText',top.frames["treeStatus"].document).hide();
For this to work the frame must have the name attribute apart from the id, like this:
<frameset rows="50%, 50%">
<frame id="treeContent" src="treeContent.html" />
<frame name="tree开发者_JAVA百科Status" id="treeStatus" src="treeStatus.html" />
</frameset>
You could grab the Frame and div you are wanting to manipulate and pass it into a variable.
var statusText = top.frames["treeStatus"].document.getElementById('statusText');
Then you can do anything you want to it through jQuery.
$(statusText).whatever();
Though sometimes you just can't get around having to use frames, keep in mind that the <frame> tag is obsoleted in HTML5. If you ever plan on moving up to HTML5, you'll have to use iFrames.
I have nested frames. In my case, to make it work i used command:
var statusText =
top.document.getElementById("treeStatus").contentDocument.getElementById("statusText");
Then, as Charles already answered, you can do anything you want to it through jQuery:
$(statusText).whatever();
https://jamesmccaffrey.wordpress.com/2009/07/30/cross-frame-access-with-jquery/
$(document).ready(function(){
$("#Button1").click(function(){
$(parent.rightFrame.document).contents().find(‘#TextBox1’).val(‘Hello from left frame!’);
});
});
But I used :
$.post("content_right.php",{id:id},function(data)
$(parent.frames["content_right"].document.body).html(data) ;
});
For a pure jquery solution (that doesn't require top.frames etc), the following seems to work:
$('some selector for item from frame' ,$('frame selector')[0].contentDocument)
This has the advantage that it works for nested frames:
$('inner frame item selector', $('inner frame selector', $('outer frame selector')[0].contentDocument)[0].contentDocument)
I used the following successfully:
$( '#foo', top.frames['bar'].document )
(also works with nested frames that are automagically appended in top.frames)
