Is it possible to dynamically set a Spring MVC portlet:actionURL portlet:param using javascript? I have tried with the following code, but the id value always comes across as null to the controller. I have verified that setting the portlet:param manually passes the value correctly:
<portlet:param name="id" value="2" />
I have also verified the value in the javascript is being set correctly and is not null.
(Note: I've changed the variable names, etc. from the original code to simplify it and obfuscate it since it is my employer's code.)
JSP:
<portlet:actionURL var="modifyURL">
<portlet:param name="do" value="modify" />
<portlet:param name="id" value="${model.id}" />
</portlet:actionURL>
...
<form:form action="${modifyURL}" id="modifyForm" modelAttribute="model">
<form:hidden path="id" id="id" />
</form:form>
Javascript called when the update URL is clicked:
function update() {
document.forms[0]["id"].value = selectedId;
document.forms[0].submit();
}
Controller:
@RequestMapping(params = {"do=modify"})
public void modify(@ModelAttribute("model") Model model,
@RequestParam(value = "id", required=true) Long id,
ActionRequest request, ActionResponse response,
SessionStatus sessionStatus, ModelMap modelMap) {
....
