js 弹出子页面和父页面交互

//此代码放在主页面main.aspx脚本区域里
// 点击主页面的添加 跳转到JCXMUPDATE页面
function AddNewData() {
          
                //居中显示
                var Url = "JCXMUPDATE.aspx?action=" + actionmethod;
                var height = 280;
                var width = 600;
                var win = OpenWin(Url, height, width, "no");
                win.focus(); //使弹出的页面得到焦点
                return false; //防止刷新页面
          
            }

//弹出页面
function OpenWin(Url, height, width) {
    var top = (screen.availHeight - height) / 2;
    var left = (screen.availWidth - width) / 2;
    var title = Url.split('.aspx')[0].replace("..", "");
    if (title.indexOf('/') != -1) {
        var begin = title.lastIndexOf('/');
        sTitle = title.substr(begin + 1, title.length - begin); //文件名
        title = sTitle;
    }
    var win = window.open(Url, title, 'height=' + height + ', width=' + width + ',top=' + top + ',left=' + left + ',  toolbar=no, menubar=no, scrollbars=yes, resizable=yes,location=no, status=no');
    return win; //使弹出的页面得到焦点
    //return false;//防止刷新页面
}

//主页面刷新方法 提供给子页面调用
function AddRefresh() //AddRefresh(id) 
{ 
 
//document.getElementById("ctl00_PageBody_Button2").click();//触发按钮的查询事件
 document.form1.submit(); 
}

 

//============JCXMUPDATE.aspx页面 子页面===============================

//子页面关闭
