How to open Modal pop up in JSF 2 using JQuery
提问by user1220373
I have a requirement that in my JSF page there will be a commandButton, and on clicking that commandButton it will fire a action method which will perform some logic and based on the outcome of that logic I will have to show a pop up with two commandButton on it. I can can not use any implementation of JSF (like RichFaces, IceFaces), I need to achieve this only using JSF 2 and JQuery. Is it possible? Any ideas or thoughts will be very helpful to me. Oh another thing I need to add the button and the same logic in several pages. I have tried using the SimepleModal plug in but was not successful to come up with a smart approach.
我有一个要求，在我的 JSF 页面中会有一个 commandButton，点击那个 commandButton 它将触发一个 action 方法，该方法将执行一些逻辑，并根据该逻辑的结果，我将不得不显示一个带有两个 commandButton 的弹出窗口在上面。我不能使用 JSF 的任何实现（如 RichFaces、IceFaces），我只需要使用 JSF 2 和 JQuery 来实现这一点。是否可以？任何想法或想法都会对我很有帮助。哦另一件事我需要在几个页面中添加按钮和相同的逻辑。我曾尝试使用 SimepleModal 插件，但没有成功想出一个聪明的方法。

Here's a complete working example
这是一个完整的工作示例
I used display:noneto hide the h:panelGroupdialog container cause the .dialog function will make it visible when its needed to be
我曾经display:none隐藏h:panelGroup对话框容器，因为 .dialog 函数将使其在需要时可见
You also can hide the real jsf command buttons and access it through dialog button with jquery # selector and invoke the .click on it like I did in the js file.
您还可以隐藏真正的 jsf 命令按钮并通过带有 jquery # 选择器的对话框按钮访问它，并像我在 js 文件中所做的那样调用它的 .click。
One last thing , used onclick="initDialog(); return false;"to call the dialog js function and added return false so the commandbutton wont try to navigate away...
最后一件事，用于onclick="initDialog(); return false;"调用对话框 js 函数并添加 return false 以便命令按钮不会尝试导航...
By using the jQuery UI Dialog you will get maximum flexibility/control over your dialogs.
通过使用 jQuery UI 对话框，您将获得对对话框的最大灵活性/控制。
The example consists from 2 file (one .xhtml and one .js) ,
该示例由 2 个文件（一个 .xhtml 和一个 .js）组成，
I used jQuery and jQueryUI , no need in any other plugins at all
我使用了 jQuery 和 jQueryUI ，根本不需要任何其他插件

and scripts.js
和scripts.js
function initDialog() {
$("#idOfDialogPlaceHolder").dialog({
modal: true,
buttons: {
SomeButton: function () {
$("#justAButton").click();
},
Close: function () {
$(this).dialog("close");
}
},
});
}
That's it
就是这样
