Many times we see some annoying javascript errors on websites.
I am of the opinion that the javascript errors should not be shown to users. Best way is to write correct javascript, but to be on safer side we can write try...catch in javascript to supress the error.
try
{
//Run some code here
}
catch(err)
{
//Just ignore...don't do anything
//Or try to handle the error
}
Alternatively we can handle the onerror event and supress all Javascript errors occuring on the page.
<script type="text/javascript">
window.onerror=function(){
//Don't do anything, just supress the error
}</script>
I hope this helps.
The ASP.NET Wiki was started by Scott Hanselman in February of 2008. The idea is that folks spend a lot of time trolling the blogs, googlinglive-searching for answers to common "How To" questions. There's piles of fantastic community-created and MSFT-created content out there, but if it's not found by a search engine and the right combination of keywords, it's often lost.
The ASP.NET Wiki articles moved to CodeProject in October 2013 and will live on, loved, protected and updated by the community.
