JS 实现获取打开一个界面中输入的值

需求

在一个界面中打开另一个界面，通过JS获取在另一个界面中用户输入的值。

示例：

Index.html

   1:  <html>
   2:  <head>
   3:  <meta http-equiv="content-type" content="text/html; charset=gbk">
   4:      <title>主页</title>
   5:     <script type="text/javascript">
   6:         function EntryPoint() {
   7:             var style = 'dialogHeight:600px;dialogWidth:800px;status:no;help:0;scrool:yes';
   8:             var a = window.showModalDialog('other.html', '', style);
   9:   
  10:             if (a == undefined) {
  11:                 a = window.returnValue;
  12:             }
  13:            // debugger;
  14:             if (a != null && a.length > 0) {
  15:                 document.getElementById("name").value = a[0];
  16:                 document.getElementById("age").value = a[1];
  17:             }
  18:         }
  19:  </script>
  20:  </head> 
  21:  <body>
  22:  <input type="button" value="调用" onclick="EntryPoint()"/><br/>
  23:  <input type="text" name="name" id="name" /><br/>
  24:  <input type="text" name="age" id="age" />
  25:  </body>
  26:  </html>

另一个界面：

other.html

   1:  <html>
   2:  <head>
   3:      <title>操作界面</title>
   4:       
   5:      <meta http-equiv="content-type" content="text/html; charset=gbk">
   6:       
   7:     <script type="text/javascript">
   8:         function postValue() {
   9:             var name = document.getElementById("name").value;
  10:             var age = document.getElementById("age").value;
  11:             var a = new Array();
  12:             a[0] = name;
  13:             a[1] = age;
  14:             //debugger;
  15:             if (window.opener != undefined) {
  16:                 //for chrome
  17:                 window.opener.returnValue = a;
  18:             }
  19:             else {
  20:                 window.returnValue = a;
  21:             }
  22:             window.close();
  23:         }
  24:  </script>
  25:  </head> 
  26:  <body>
  27:  <input type="button" value="确定" onclick="postValue();"/><br/>
  28:  名字:<input type="text" name="name" id="name" /><br/>
  29:  年龄:<input type="text" name="age" id="age" />
  30:  </body>
  31:  </html>

 

在该DEMO中遇到一个问题，那就是chrome中window.close()方法不起作用。最后通过，window.opener来解决chrome和IE的冲突。
