    Accessing the expression language in javascript of a jsp page - Stack Overflow

    programmeradmin3浏览0评论

    I have a "jsp" file. In that file I have "Javascript" scripting. Within <script> tags,only javascript is allowed but, how is "Expression Language" executed?

    <body>
    <script type="text/javascript">
        var b=${requestScope.name};
    </script>
</body>

    Reset to default 5

    bring that variable from request scope to page scope,

    <c:set var="myVar" value="${request.myVar}" />

    after this you can try this :

    <script>
    var myVar= '${myVar}' ;
</script>

    Though I am not sure if it's the best approach; but this should do.

    Executed.

    As "Expression Language" is executed on the server side the statement 

    ${requestScope.name}

    executed at server side and its value is available to JavaScript at client side. now at the client side the line bees 

    var b='corresponding expression language executed value';

    JSP is server side. You cannot access the script variables. These variables are only executed client-side.
