JSP EL + jQuery "$.ajax()" problem
I have simple JSP:
<jsp:directive.attribute name="severity" type="java.lang.String" required="true"/>
<jsp:directive.attribute name="currentSeverity" type="java.lang.String" required="true"/>
<c:if test="${severity ne currentSeverity}">
<c:url value="/session" var="url">
<c:param name="severity" value="${severity}"/>
</c:url>
<li><a href="#" onclick="$.ajax({
t开发者_Go百科ype: 'GET',
url: '${url}',
success: function() {
window.location.reload();
}
});"><c:out value="${severity}"/></a></li>
</c:if>
But when I'm evaluate it servlet engine throws:
org.apache.jasper.JasperException:
/WEB-INF/tags/severity-position.tagx(17,9) PWC6287:
The attribute prefix success does not correspond to any imported tag library
Somehow JSP engine thinks that $.ajax({...}); string is JSP EL expression (no matter what characters are placed between $ and {). When I backslash { or $ it's all ok, but then my IDE thinks that this code is broken JS code.
So, why JSP engine thinks that $.ajax({...}) is JSP EL expression?
This look indeed like a bug in the EL implementation used by the servletcontainer (or webapplication) in question. You need to figure which one it is using and try upgrading/replacing it.
If upgrading/replacing the EL implementation doesn't help, then I'd warmly recommend do move that whole script out into an function in its own .js file which you load using <script> in the HTML <head> element. That's also the normal practice. Even more, I'd give the link a classname so that you can just hook on it during $(document).ready() and add the click() accordingly. E.g.
<a href="${url}" class="someName">
with
$(document).ready(function() {
$('.someName').click(function() {
$.ajax({
type: 'GET',
url: $(this).attr('href'), // This sets the actual value of ${url}.
success: function() {
window.location.reload();
}
});
return false; // Blocks link from executing the default href action.
});
});
