以下是看到的一个例子：
1.父窗体main.html：
1 <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> 2 <HTML> 3 <head> 4 <script type="text/javascript"> 5 function OpenChildWindow () { 6 window.open ("sub.html", "OpenerTest", "width=300, height=200"); 7 //window.showModalDialog("sub.html", window); 8 } 9 </script> 10 </head> 11 <body> 12 <button id="childOpener" onclick="OpenChildWindow();">Open child window!</button> 13 <br /><br /> 14 </body> 15 </HTML>
2.子窗体sub.html：
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="utf-8" /> 5 <title>Modeless window example</title> 6 <script type="text/javascript"> 7 function ChangeOpener (selectTag) { 8 //if(window.opener == undefined) { 9 // alert("undefined"); 10 //} 11 var openerWindow = window.opener; 12 var button = openerWindow.document.getElementById ("childOpener"); 13 button.style.color = selectTag.options[selectTag.selectedIndex].text; 14 } 15 </script> 16 <body> 17 Change the color of the button in the opener window: 18 <select onchange="ChangeOpener(this)"> 19 <option>black</option> 20 <option>red</option> 21 <option>blue</option> 22 <option>green</option> 23 </select> 24 </body> 25 </html>
在chrome下折腾了一阵子，始终没有效果，IE、FF没问题，论坛中看到一位朋友解释如下(未测)：
“本地file浏览器测试不要用chrome（webkit核心的浏览器），不能互相操作”。
