为什么页面不重定向到edit.jsp？

Question

My code is as follows:-

<portlet:actionURL var="editGreetingURL">
<portlet:param name="mvcPath" value="/html/urldemo/edit.jsp" />
</portlet:actionURL>

<aui:form action="<%= editGreetingURL %>" method="POST"> 

<aui:input type="submit" name="Submit"/>
</aui:form>

On clicking submit I am not redirected to edit.jsp..Why?

Answer 1

You should look into the main tags in Liferay if you want to become a professional. :D

First of all, you should understand the portlet's lifecycle. You can google it easily.

<portlet:actionURL calls action phase of your portlet.

<portlet:renderURL calls render phase of your portlet.

So, when you try to do this:

<portlet:actionURL var="editGreetingURL">
    <portlet:param name="mvcPath" value="/html/urldemo/edit.jsp" />
</portlet:actionURL>

you try to call action method which is not defined correctly yet.

Answer 2

尝试：

<aui:form action="<%= editGreetingURL.toString() %>" method="POST">
