我有一个create_account.jsp的钩子.
在这个jsp我有一个 javascript代码,我尝试在iframe弹出窗口或Liferay的一些弹出窗口中打开一个portlet.
在这个jsp我有一个 javascript代码,我尝试在iframe弹出窗口或Liferay的一些弹出窗口中打开一个portlet.
问题是:
如何提供portlet URL?
我该如何访问它?
在该portlet中,我只想问一个YES或NO的问题,并根据用户的答案,重定向到其他页面.
解决方法
>要创建URL,您可以使用< portlet:renderURL>或者< liferay-portlet:renderURL>
- <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.
