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.
