Question:
Let me explain the purpose of this. I'm using some CMS and I'm trying to customize it with php scripts of my own that I embedded to the home page with IFRAME. My php script gives back some links which I would like to open outside that IFRAME - as a part of some other CMS block on the homepage. The idea is to target (from my php script) the div of that CMS block which is already showing some data. Is that possible?
Answer1:If you need to access <div>
or any other element of parent window
from its child iframe
USE:
var elem=window.parent.document.getElementById('target');
inside <script>
tag of iframe
's document.
ex.
file: index.html (Give any name).
<html>
<body>
<div id="div_to_use_from_parent">Blah!</div>
<iframe src="xyz.php" width="xx" height="xx"></iframe>
</body>
</html>
file: xyz.php (same as src of iframe)
<?php
echo<<<html
<html>
<head>
<script type="text/javascript">
function do_blah(){
var elem=window.parent.document.getElementById('div_to_use_from_parent');
elem.innerHTML="iframe changed My Content!";
}
</script>
</head>
<body onLoad="do_blah();">
This is iframe
</body>
</html>
html;
?>
OR
if you need to access element in iframe
from parent window
USE:
var iframe = document.getElementById('idOfIframe');
var frame = iframe.contentDocument || iframe.contentWindow.document;
var yourDiv= frame.getElementById('div_you_want');
inside <script>
tag of parent window
's document.
ex.
file: index.html (Give any name).
<html>
<head>
<script type="text/javascript">
window.onload=function(){
var iframe = document.getElementById('idOfIframe');
var frame = iframe.contentDocument || iframe.contentWindow.document;
var elem= frame.getElementById('div_from_iframe');
elem.innerHTML+="<br /> And Parent window added this!";
};
</script>
</head>
<body>
<div id="div_to_use_from_parent">Blah!</div>
<iframe src="xyz.php" width="xx" height="xx"></iframe>
</body>
</html>
file: xyz.php (same as src of iframe)
<?php
echo<<<html
<html>
<body>
<div id="div_from_iframe"> This div from iframe</div>
</body>
</html>
html;
?>
parent window
is the one in which original html
(index.html) document along with your iframe
(xyz.php) resides.
Hope it helps :-)!
Answer2:
var iframe = document.getElementById('idOfIframe');
var frame = iframe.contentDocument || iframe.contentWindow.document;
var yourDiv= frame.getElementById('div_you_want');
Answer3:From the page running inside the <iframe>
you can refer to the parent page as window.parent
, and perform actions as you normally would.
parent.document.getElementById('target_div').innerHTML = 'New content.';
Note JavaScript's cross-domain restrictions apply. You can only do that if both pages belong to the same domain.
In case of links, you can include to your <a>
tags the attribute target="_parent"
, or set it as base target to apply to all links.
<head>
...
<base target="_parent">
</head>
You can also target a link to another iframe
, all you have to do is set a name="iframe_name"
to it and set target="iframe_name"
to all links that should open in that area.
