Answer 1

有两种方法可以解决问题:注意:如果使用" showModalDialog ",则IE不支持" window.opener " .

1)使用" window.open " 代替" window.showModalDialog "

2)如果要使用" window.showModalDialog ",请执行以下操作:

<script language="javascript" type="text/javascript">
    function YourFunction()
    {
        var opener = null;

        if (window.dialogArguments) // Internet Explorer supports window.dialogArguments
        { 
            opener = window.dialogArguments;
        } 
        else // Firefox, Safari, Google Chrome and Opera supports window.opener
        {        
            if (window.opener) 
            {
                opener = window.opener;
            }
        }       
        // write you code and refer "opener"
        window.close();
    }
</script>

您可以将参数传递给showModalDialog函数.只需将window对象作为参数传递即可.

window.showModalDialog(theURL, window);

Yo可以使用dialogArguments从模态窗口访问参数.请参阅:http://msdn.microsoft.com/en-us/library/ms533723%28VS.85%29.aspx

var openerWindow = window.dialogArguments;
