lodoss1118 Help needed with getting values from iframe in visualforce page
Hi i am trying to get some values from the send email wizard form within my visualforce page:
<apex:page >
<script>
function GetFrameWindow(event)
{
alert(event);
var iFrame = document.getElementById(event);
alert(iFrame);
var oDoc = iFrame.contentDocument;
alert(oDoc);
}
</script>
<apex:form >
<apex:commandButton value="Check" onclick="GetFrameWindow('theIframe');"/>
<apex:inputTextarea richText="true" cols="2" rows="2"/>
<center>
<apex:iframe id="theIframe" src="/_ui/core/email/author/EmailAuthor?p3_lkid=000000011111111&retURL=%2F01111111111111&template_id=1111111111111111&isdtp=mn" scrolling="true" frameborder="true" width="800" height="600"/>
</center>
</apex:form>
</apex:page>
but everytime i try to get something from oDoc it is always null?
This is because the browser is protecting the user from cross site scripting. As the iframe comes from a different server to your Visualforce page, the browser doesn't allow you to access the values from the DOM.
Hi,
Below is my VF Code
JS
function getFrameContent(){
var iframe = document.getElementsByTagName('iframe')[0];
alert(iframe);//working fine
doc = iframe.contentWindow;
alert(doc);//working fine
alert(doc.body);//undefined
alert(doc.body.innerHTML);
}
<form id="secondForm" name="secondForm" method='POST' enctype='multipart/form-data'
action="http://someurl" target="responseFrame" >
</form>
<input type="button" name="btnid" value="Test To Get Frame Data" onclick="getFrameContent()" />
From this I am getting response into IFrame.
After that I need to get the data from Iframe.
Plase provide JS code such that I can access frame content./ Where I did mistake.
But in normal html page it is working fine.
ThankU.

If you are attempting to access the contents of an iframe from a different server to that where the javascript is served from, you cannot do this.
