java – PortletURL在弹出窗口中打开另一个portlet

<liferay-portlet:renderURL
    var="testPopupURL"
    portletName="testPopup_WAR_testPopupportlet"
    windowState="<%=LiferayWindowState.POP_UP.toString() %>">
    <liferay-portlet:param name="paramToPopup" value="customParameterToThePortlet" />
</liferay-portlet:renderURL>

portletName =“testPopup_WAR_testPopupportlet”这是您要打开的portlet的portletId.

windowState =“<％= LiferayWindowState.POP_UP.toString()％>”这对于在弹出窗口中显示portlet非常重要,否则它将打开带有导航和所有内容的完整liferay页面.
>您可以在JSP中编写以使用上述URL并在其中打开弹出窗口和portlet的javascript：

// this is one of creating function
function <portlet:namespace />showPopup(url) {

    var url = url;

    // this is one way of calling a pop-up in liferay
    // this way is specific to liferay
    Liferay.Util.openWindow(
            {
                dialog: {
                    cache: false,width:800,modal: true
                },id: 'testPopupIdUnique',uri: url
            }
        );
    }

// this is another way of creating a function in liferay
Liferay.provide(
        window,'<portlet:namespace />showAUIPopUP',function(url) {
            var A = AUI();

            // this is another way of calling a iframe pop-up
            // this way is not specific to liferay
            popupDialog = new A.Dialog(
                {
                    id: 'testPopupIdUnique',centered: true,draggable: true,resizable: true,width: 800,stack: true
                }
            ).plug(
                A.Plugin.DialogIframe,{
                    uri: url,iframeCssClass: 'ogilvy-dialog-iframe'
                }
            );

            popupDialog.render();
        },['aui-dialog','aui-dialog-iframe']
);

>您可以简单地将这些javascript函数称为：

<a href="javascript: <portlet:namespace />showPopup('<%=testPopupURL%>')">
    Popup using Liferay open-window
</a>

<a href="javascript: <portlet:namespace />showAUIPopUP('<%=testPopupURL%>')">
    Pop-up using Alloy UI dialog
</a>

>将在弹出窗口的iframe内显示的portlet应该具有< add-default-resource> true< / add-default-resource>在liferay-portlet.xml中：

<portlet>
    <portlet-name>testPopup</portlet-name>
    <icon>/icon.png</icon>
    <instanceable>false</instanceable>
    <header-portlet-css>/css/main.css</header-portlet-css>
    <footer-portlet-javascript>/js/main.js</footer-portlet-javascript>
    <css-class-wrapper>testPopup-portlet</css-class-wrapper>
    <!-- This property is necessary otherwise you would see a "Access denied for portlet" message when you try to open this portlet dynamically -->
    <add-default-resource>true</add-default-resource>
</portlet>

>或者应该将portal-ext.properties中的属性portlet.add.default.resource.check.whitelist作为：

portlet.add.default.resource.check.whitelist=3,56_INSTANCE_0000,58,82,86,87,88,103,113,145,164,166,170,177,testPopup_WAR_testPopupportlet

要查看此代码的实际操作,您可以从中下载2个portlet并参考this liferay forum中的说明.

希望这有助于更好地理解liferay.
