I can't put any id or class to the iframe I work because of some technical issues, and this iframe sometimes don't show any content inside and I am having a blank space instead. I wanted to make the iframe disappear when it loads blank, to protect my page's structure with javascript.
Here is the code I wanted to make it disappear when there are no contents.
<div id="myDiv">
<iframe width="363" height="300" src="javascript:false">
<div id="iframeDiv">
----Contents----
</div>
</iframe>
</div>
I tried below script but somehow it doesn't work. Thanks in advance.
<script type="text/javascript">
setTimeout(function () {
var myTag=document.getElementById('myDiv').getElementsByTagName('iframe');
var myTagContent = myTag.contentDocument || iframe.contentWindow.document;
var myTagDiv = myTagContent.innerDoc.getElementById('iframeDiv');
if (myTagDiv === null)
{
document.getElementById("myDiv").style.display = "none";
}
}, 500);
</script>
Remove the outer <div>
before <iframe>
.
Add id="ifr"
to <iframe>
tag.
Then: iframeDivElement = window.parent.getElementById('ifr').document.getElementById(iframeDiv');
EDIT : Alternatively you can use iframe index in your document.
iframeDivElement = window.parent.frames[0].document.getElementById(iframeDiv');
