Question

我有一个从弹出对话框中获取输入的应用程序。当用户在弹出对话框的文本字段中输入文本时。我需要将该文本传递给另一个类中的另一个方法。如何实现这一点。我的代码如下所示。

viewRoles.jsp

    <%@page contentType="text/html"  import="com.model.Data" pageEncoding="UTF-8"%>
<!DOCTYPE html>
<html>
    <head>
       <link href="bootstrap.css" type="text/css" rel="stylesheet">
       <script>
          window.onload=function()
          {
                var el=document.getElementById('btnAddNewRole');
                el.onclick=function()
                {
                var my_text=prompt('Enter text here');
                if(my_text){
                    $.ajax({
                    url: '/com.model/Data/addRole('+my_text+')',
                    success: function(my_text){
                    alert("Inserted")
                    }, error: function(){
                    // when got error
                    }
                    });
                }
                }
          }
        </script>
        <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
        <title>View Roles</title>
    </head>
    <body><br><br>
           <button id="btnAddNewRole" class="btn btn-info">Add New Role</button>
    </body>
</html>

com.model包中的Data.java

package com.model;


import javax.faces.bean.ManagedBean;
import javax.faces.bean.SessionScoped;
import org.hibernate.Session;

@ManagedBean
@SessionScoped
public class Data {
    private Roles r;
    private HibernateUtil helper;
    private Session session;

    public void addRole(String roleTitle){
        r=new Roles(roleTitle);
        session = helper.getSessionFactory().openSession();
        session.beginTransaction();
        session.save(r);
        session.getTransaction().commit();
        session.close();
    }

如何在javascript中的不同java类中调用方法
