How to get render parameter

Question

I want to get render parameter.

I wrote the following aui:script for opening new dialog. In that script I set parameter.

<input type="text" name="<portlet:namespace/>weburl" size="75: id="weburl" label="" inlineField="true"  />  
<aui:button name="btnPreview" id="btnPreview" value="Preview"/>

<aui:script>
    AUI().use('aui-base','aui-io-plugin-deprecated','liferay-util-window','liferay-portlet-url', 'aui-dialog-iframe-deprecated', function(A) {
        A.one('#<portlet:namespace />btnPreview').on('click', function(event){

            alert(document.getElementById('weburl').value)
            var strUrl=document.getElementById('weburl').value;
            var renderURL =Liferay.PortletURL.createRenderURL();
            renderURL.setParameter("nameUrl",strUrl);
            renderURL.setParameter("mvcPath",'/html/view2.jsp');
            renderURL.setPortletId("Portlets_WAR");
            renderURL .setWindowState("pop_up");

            alert(renderURL.toString());

            var popUpWindow=Liferay.Util.Window

                .getWindow({
                    dialog: {
                        centered: true,
                        constrain2view: true,

                        modal: true,
                        resizable: false,
                        width: 500
                    }
                })

                .plug(A.Plugin.DialogIframe, {
                    autoLoad: true,
                    iframeCssClass: 'dialog-iframe',
                    uri:'<%=portletSettingsURL.toString()%>'
                })

                .render();

            popUpWindow.show();
            popUpWindow.titleNode.html("Image Preview");
            popUpWindow.io.start();
        });
    });
</aui:script>

Using this script i redirect to my view2.jsp and open that page in dialog succesfully. Here I also set the parameter using :

var strUrl=document.getElementById('weburl').value var testurl =Liferay.PortletURL.createRenderURL(); testurl.setParameter("name",strUrl);

My portal:renderURL is as follow

 <portlet:renderURL var="portletSettingsURL"
 windowState="<%=LiferayWindowState.POP_UP.toString()%>">
       <portlet:param name="mvcPath" value="/html/view2.jsp"/>
         </portlet:renderURL>

My view2.jsp file is as follow

 <%

String str1=renderRequest.getParameter("nameUrl");

System.out.print("value " +str1);

%>

I want to send my weburl textbox value to view2.jsp file

I just want the value of name in my view2.jsp file How can I get my value in view2.jsp file?

Answer 1

Have you tired the ParamUtil class?

ParamUtil.get(request, param, defaultValue).

For putting params to the URL you can check this. This is for scriptlet but you can use it in AUI script too.

Edit: You can add your parameter to the URL like this:url = url + '&<portlet:namespace/>yourParamName=yourParamValue'
