${pagecontext.request.contextpath in JavaScript and solution _javascript skills

In the JSP to take the ${pageContext.request.contextPath}， way one can be normally taken, but the way two but take the

Character " ${pageContext.request.contextPath} "

Mode one:

<script type= "Text/javascript" >
var t = "${pagecontext.request.contextpath}";
<script>

Mode two:

<script src= "${ctx}/jqgrid.js" type= "Text/javascript" > 
</script>
jqgrid.js:
function Jqgridinclude ()
{
var t = ' ${pagecontext.request.contextpath} ';
}
Jqgridinclude ();

-----Solution--------------------

That's because ${pagecontext.request.contextpath} is not javascript at all, but the El of JSP. You write ${pagecontext.request.contextpath} into a JS file, the JSP compiler does not deal with it at all.

${} is an El expression. Can only be used in JSP files. JS file with this is a string.

The above is a small set of JavaScript to introduce ${pagecontext.request.contextpath} value problems and solutions, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone.
