JS模态窗口返回值兼容问题解决方案

1、打开弹出窗口时把 window 作为第二个参数传入。

 var result = window.showModalDialog(url, window, "dialogWidth=" + width + "px;dialogHeight=" + height + "px;resizable:yes;")

 if (typeof (result) == 'undefined') {

         result = window.ReturnValue;

     }

     return result;

2、在弹出窗口中，执行如下JS，以接收传入的window

 if (typeof (window.opener) == 'undefined') window.opener = window.dialogArguments;

3、弹出窗口关闭前，调用如下JS赋返回值

 window.retureValue = vals;

        if (window.opener && window.opener != null)

                window.opener.ReturnValue = vals;

        window.close();
