window.open返回值实例详解(子窗口向父窗口回显)

window.open实例：

1、父页面：

<script language="javascript" type="text/javascript">
   var wd;
   var winTimer;//计时器变量, 监听窗口关闭 
   function openWindow() 
         wd = window.open("test2.html",null," height=300,width=450,  Left=300px,Top=20px, menubar=no,titlebar=no,scrollbar=no,toolbar=no, status=no,location=no");
         if (wd)  
          window.wd.focus();//判断窗口是否打开,如果打开,窗口前置  
          winTimer=window.setInterval("wisclosed()",500);
   
   function wisclosed()
    if(wd.closed)  
      alert(window.returnVaule);//子窗体返回值  
      //这里可以做赋值操作  
      window.clearInterval(winTimer);  
      
   
 </script>
</head>
<body>
 <input type="button" id="btnShow" onclick="openWindow();"  value="显示子窗口"/>
</body>

2、子页面：

<script language="javascript" type="text/javascript">
   function doclose() 
    window.opener.window.returnVaule="ok";  
    parent.window.close(); 
  
</script>
</head>
<body>
 <input type="button" id="btnSelect" onclick="doclose();"  value="关闭"/> 
</body>

下面是实例代码：index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";

         if (wd)  
          window.wd.focus();//判断窗口是否打开,如果打开,窗口前置  
          winTimer=window.setInterval("wisclosed()",500);
   
   function wisclosed()
    if(wd.closed)  
      alert("回显1111111111111111"+window.returnVaule);//子窗体返回值  
      //这里可以做赋值操作  
      window.clearInterval(winTimer);  
      
   
 </script>
  </head>
  
  <body>
  <input type="button" id="btnShow" onclick="openWindow();"  value="显示子窗口"/>

index2.jsp

下面讲一个在项目中的回显例子：window.open

这是父窗口zhibiaoAll.jsp 这个页面的

我需要拿到子窗口teaAll.jsp，传回来的值，用于教师的选择，然后进行  document.getElementById("tea_id").value=window.returnVaule;  进行数据的回显（把回显值赋值在老师那个输入框中）

那么怎么做呢？

这是在zhibiaoAll.jsp，父窗口的js代码

<script language="javascript" type="text/javascript">
   var wd;
   var winTimer;//计时器变量, 监听窗口关闭 
   function openWindow() 
         wd = window.open("<%=path %>/tea?type=teaAll",null," height=300,width=450,  Left=300px,Top=20px, menubar=no,titlebar=no,scrollbar=no,toolbar=no, status=no,location=no");
         if (wd)  
          window.wd.focus();//判断窗口是否打开,如果打开,窗口前置  
          winTimer=window.setInterval("wisclosed()",500);
   
   function wisclosed()
    if(wd.closed)  
      alert("回显1111111111111111"+window.returnVaule);//子窗体返回值  
      //这里可以做赋值操作  
        document.getElementById("tea_id").value=window.returnVaule;
      window.clearInterval(winTimer);  
      
   
   
          function StringBuffer()
             
			   this._strs = new Array; 
			 
			StringBuffer.prototype.append = function (str) 
			 
			   this._strs.push(str); //添加
			 
			StringBuffer.prototype.pop = function (str) 
			 
			   this._strs.pop(str); //删除最后一个
			 
			StringBuffer.prototype.toString = function()
		     
			   return this._strs.join(","); 
			
		    
		    var sb = new StringBuffer();
		    <c:forEach items="$requestScope.zhibiaoList" var="zhibiao">
		        sb.append($zhibiao.id)
		    </c:forEach>
		    
		  
   
    function check()
            
                if(document.getElementById("tea_id").value=="")
		        
		            alert("请选择老师");
		            return false;
		        
                document.getElementById("zhibiao_id").value=sb.toString();
                
                document.formAdd.submit();
            
            
            
            
       
 </script>

这是在teaAll.jsp，子窗口的js代码

        <script language="javascript">
            function StringBuffer()
             
			   this._strs = new Array; 
			 
			StringBuffer.prototype.append = function (str) 
			 
			   this._strs.push(str); //添加
			 
			StringBuffer.prototype.pop = function (str) 
			 
			   this._strs.pop(str); //删除最后一个
			 
			StringBuffer.prototype.toString = function()
		     
			   return this._strs.join(","); 
			
            
            function queding()
            
                 var sb = new StringBuffer(); 
                 
                 var object=document.getElementsByName("tea_id");//返回的obeject是数组
				 for(i=0;i<object.length;i++)
				 
				      if(object[i].checked==true)
					  
					      sb.append(object[i].value); 
					  
				 
				 //alert("值"+sb.toString());				         
		          window.opener.window.returnVaule=sb.toString();  
                  parent.window.close(); 
            
        </script>
