如何以编程方式添加带有撇号的对话框 [英] How to programmatically add dialogs with primefaces

问题描述

我想通过primefaces数据列表组件显示一些数据.为了实现这一点，我有一个ArrayList<Person>之类的arrayList.

I want to display some data through primefaces datalist component. To achieve this I have an arrayList like ArrayList<Person>.

人类看起来像这样

class Person{
    private String name;
    private String age;
    private ArrayList<String> hobbies;
}

使用以下代码显示我正在使用的数据:

To display the data I'm using the following code:

<p:dataList value="{gameBean.persons}" var="person" itemType="disc">  
    Name: #{person.getName()}, Age: #{person.getAge()}, 
    <h:link value="Hobbies" onclick="dlg1.show();" />
</p:dataList>

我现在要做的是创建一个链接，单击该链接可打开一个对话框:

What I want do do now, is to create a link that opens a dialog when clicked:

 <p:dialog header="Hobbies" widgetVar="dlg1" modal="true"height="100">
    //iterate through hobbies list to print it 
 </p:dialog>

到目前为止，这是可行的，因为如上所述，我已经在xhtml文件中对对话框进行了硬编码.

So far this is working because I've hard coded the dialog as mentioned above in the xhtml file.

由于无法对对话框和链接进行硬编码，因此这种方法对于大量的人当然不起作用.我的问题是，如何才能以编程方式创建此对话框并将正确的widgetVar变量分配给链接的onClick方法?

This method is of course not working for a dynamic amount of persons as I can not hard code the dialogs and the links. My question is, how can I create this dialogs programmatically and assign the right widgetVar variable to the onClick method of the Links?

我们非常感谢您的帮助， 尼古拉斯欢呼

推荐答案

您可以尝试以下操作:

<h:form id="form">
    <p:dataList value="{gameBean.persons}" var="person" itemType="disc">  
        Name: #{person.getName()}, Age: #{person.getAge()}, 
        <p:column>
            <p:commandLink value="Hobbies" actionListener="#{gameBean.onPersonSelect(person)}" 
                       oncomplete="dlg1.show();" update=":form:hobbiesDlg" />
        </p:column>
    </p:dataList>

    <p:dialog header="Hobbies" id="hobbiesDlg" widgetVar="dlg1" modal="true"height="100">
        //iterate through hobbies of gameBean.person to show here
    </p:dialog>
</h:form>

@ManagedBean
@ViewScoped
public class GameBean {
   private Person person;

   public void onPersonSelect(Person person) {
      this.person = person;
   }
}
