<head> #set($test = "works")) </head>
<script>
var get = "${test}"; // I also tried using '$test' and "$test" also
alert(get);
</script>
And it alerts out ${test}, but should print works.
How can I get it to work?
回答1:
try this...
#set ($test = "works")
<script type="text/javascript">
var myvar = "${test}";
alert (myvar);
</script>
THIS WORKS SURELY!!!!
回答2:
Try var get = "$test"; instead of var get = "${test}";

I realize the question is old, but this worked for me:
#set ($test = "hi")
<script>
alert("$test");
</script>
Need to include quotes around the variable in the alert since it is a string.

I had that problem while using tiles, the only way i got it to work was to use the jstl c:out tag, like:
var get = "<c:out value='${test}' />";
that should work, and remember to add the jstl include on the top of the page
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%>

Just use it as in html:
<script>
var get = $test;
alert(get);
</script>
