Just a simple test out of boredom.
All browsers were launched with a blank page and then navigated to Google home page. At this point, Chrome consumes the least memory of the three.
However, when opened up more tabs (Google, Yahoo and MSN), Chrome actually takes up more memory.
Google Chrome uses multi-processes instead of multi-threads for its tabs in order to prevent events such as a tab crashes whole browser (which is also the behavior of IE 8), which would be the most likely explanation for the test result.
Sometimes when you submit a form, you may wanna disable the submit button. (e.g. When the user is posting a order / payment).
The first idea popped up in my head was like this:
<form action="http://www.google.com/search">
<input name="q" type="text" />
<input onclick="this.disabled=true; window.alert('test');" type="submit" />
</form>Actually I was using similar code in a real life application for a client. Then he told me it can’t work. After a little test I found out that IE 7 won’t submit the form when you disable the submit button. Firefox can handle it properly though.
And as I’m messing around with IE 8, I found they fixed the bug.
To test it, go to http://playground.softboysxp.org/post_test.html , type something and hit the button. You should see a message box, then the query will be submitted to Google. While in IE7, the form won’t get submitted.
