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.
