Google不兼容ShowModalDialog()弹出对话框的解决办法

<script type="text/javascript">
        //弹窗函数
        function openDialog() {
            var url = "https://www.xxxx.com/UI/Test.aspx?uid=111&Userid=luke";
　　　　　　　//调用实例　
            var modalReturnValue = myShowModalDialog(url, window, 450, 500);
            //alert(modalReturnValue.name);
        }
        //弹出框google Chrome执行的是open
        function myShowModalDialog(url, args, width, height) {
            var tempReturnValue;
            if (navigator.userAgent.indexOf("Chrome") > 0) {
                var paramsChrome = \'height=\' + height + \', width=\' + width + \', top=\' + (((window.screen.height - height) / 2) - 50) +
                    \',left=\' + ((window.screen.width - width) / 2) + \',toolbar=no, menubar=no, scrollbars=no, resizable=no, location=no, status=no\';
                window.open(url, "newwindow", paramsChrome);
            }
            else {
                var params = \'dialogWidth:\' + width + \'px;dialogHeight:\' + height + \'px;status:no;dialogLeft:\'
                            + ((window.screen.width - width) / 2) + \'px;dialogTop:\' + (((window.screen.height - height) / 2) - 50) + \'px;\';
                tempReturnValue = window.showModalDialog(url, args, params);
            }
            return tempReturnValue;
        }
    </script>

返回值写法

            protected void Page_Load(object sender, EventArgs e)
            {
                if (!Page.IsPostBack)
                {
                    Response.Write("<script>window.returnValue = \'返回值OK\'; </script> ");
                }
            }
