Question

我的Liferay有问题。我正在做以下事情：

function deleting() {
    <portlet:actionURL var="deletePolyURL"> 
        <portlet:param name="jspPage" value="/deletePoly.jsp" /> 
    </portlet:actionURL>  

    <portlet:renderURL var="listingURL"> 
        <portlet:param name="jspPage" value="/listing.jsp" /> 
    </portlet:renderURL>

    $.post(
        "<%=deletePolyURL%>",
        {
            ids:ch.toString()
        },
        function(per) {
              $("#WRAPlist").load("<%=listingURL%>");
               }
    );
}

<div>已重新加载，但在此<div>中，整个Liferay页面已加载而不仅仅是我的页面，请参见图像的右侧。

我做错了什么？

deletePoly.jsp

              String st = ParamUtil.getString(request,"ids");
              out.println("NE TORT");
                        String[] id_str;
                        id_str=st.split(",");

我刷新问题。

Answer 1

我建议您需要<portlet:resourceURL>而不是renderURL来加载jsp，因为它是一个ajax请求，您需要在portlet类中使用serveResource方法加载listing.jsp。

<portlet:resourceURL var="listingURL"> 
    <portlet:param name="jspPage" value="/listing.jsp" /> 
</portlet:resourceURL>

希望这有帮助。

Answer 2

如果您不想通过资源处理来自行处理整个Ajax调用，您还可以将回复限制为仅包含portlet，而不是整个页面：

<%@ page import="com.liferay.portal.kernel.portlet.LiferayWindowState" %>

<portlet:actionURL var="deletePolyURL" windowState="<%=LiferayWindowState.EXCLUSIVE.toString() %>"> 
    <portlet:param name="jspPage" value="/deletePoly.jsp" /> 
</portlet:actionURL>

看看这是否有帮助 - 否则你应该像Prakash建议的那样使用<portlet:resourceURL>（并在你的portlet的资源服务方法中处理这个过程。

刷新portlet的<div>标记中的内容</div>
