iframe height is giving wrong value
- by user1668527
I have HTML page which contains line:
<iframe id="xyz" width="900" height="250" scrolling="no"..></iframe>
From my firefox extension i'm trying to get the iframe height.
so i'm registering the browser to a event as follow in my extension:
appcontent.addEventListener("DOMContentLoaded",myfunction);
where appcontent is browser object,
myfunction(event): function
{
var framelist =window.content.document.getElementsByTagName("iframe");
for(var i=0;i<framelist.length;i++)
{
if(framelist[i].id == "xyz")
var frameheight=framelist[i].height;
}
}
when i tried to load this page intially frameheight gives 250 as per in html page but then it gives 0 as height.
What would be the cause for this behaviour. is any other script changing the value of iframe height in between ?
Help me
