I have javascripts folder under root folder , its all workig fine till now. Suddenly it started giving me the following error for all the javascripts under scripts folder.

I the only change i made today is , deployed some files under website root dir开发者_开发百科ectory which are asp files. I didn't deploy any files to scripts folder at all.

You web server is set up to think that .js files are server-side JavaScript and you are in a directory with Execute permission. You need the Execute permission if you have .asp there. Go to your IIS settings and find the list of handlers (not mime-types) and make sure that .js isn't listed.

Or, you could just move the .js files to a folder without execute permission in IIS.

This error appeared when there was no file specified. Example:

<script type="text/javascript" src="~/Scripts/"></script>  <!-- broken -->
<script type="text/javascript" src="~/Scripts/<filename>.js"></script>
