I have a small code in my page with
<script type="text/javascript">
function doPost() {
document.forms["form"].submit();
}
function Func1Delay()
{
setTimeout("doPost()", 0);
}
....
<body onload="Func1Delay()">
I have this error in the console saying
Uncaught TypeError: Cannot call method 'create' of undefined
and on the right, it's due to the chrome extension MeasureIt. When I disable it, my script works. Is there a workaround for this problem?

The short answer is YES. But the complete answer is NO, it's not Chrome, but some extension who interfere with your code. For example:
1) A content script can add a listener and use stopPropagation. In this case your code won't receive that event. I can image a more specific scenario where the content script fails and therefore prevents other listeners to execute.
2) A content script can mess with your page's elements. It can remove some, and add its owm. What would happen if the extension add a SCRIPT element with a var or function named exactly the same that one of yours?
We cannot be sure about how "well" the extension's code is written.
By the way, there is a lot of Chrome's extensions that interfere with pages. Some months ago Skype extension for Chrome was found guilty of interfere and destabilize web pages and video playback in that browser.
