javascript code not working

<script language="JavaScript" type="text/javascript">
    if (location.href.indexOf('?dest=') > 0)
        window.open('/about.aspx', 开发者_运维技巧'', '')
</script> 

how do i make this work. Its in aspx file.

The following script will test for the existence of the 'dest=' key in the current page's querystring, and if it exists, will open a window to about.aspx with the querystring appended to the URL.

<script language="JavaScript" type="text/javascript">
if (window.location.search.indexOf('dest=') > 0) {
    window.open('/about.aspx' + window.location.search, '', '');
}
</script>

Change the window.open line to

window.location = '/about.aspx';

Include the semicolon, which is missing in your code.

Your issue is the location.href... part. It needs to be window.location.href...

if (window.location.href.indexOf('?dest=') > 0){
    window.open('/about.aspx'+window.location.search, '', '');
}

Cheers
