JavaScript function arg into JSTL

Question

1. is there a way to move a javascript function-arg into JSTL tag?

    function loadList(listName) { <c:forEach var="item" items="${listName}">.... }

2. Why did this code"

    x = '${item.category}';

   work all good and suddenly it didn't work, but change to

   x = "${item.category}";

   does work? I did alert( message ) in page load to check if the page load success.

Answer 1

I don't think it is possible to put a javascript variable into a JSTL tag without a "postback" or reload of the page. However, the reverse (ie, putting a JSTL tag value into a javascript variable) should be possible.

The reason is the separation between server-side (JSTL) and client-side (Javascript) code.

Answer 2

• With 1st question as what I know, you cant. Instead the reverse of it as your example in 2nd question. As what @jordan mentioned.
• In your 2nd question, I'm not sure why, may be you pass a value with ' or single qout on the list.category .
