javascript 函数,可以放在一个外部的common.js文件中

引入:<script src="http://www.cnblogs.com/js/common.js" type="text/JavaScript"></script>

openwindow(url,name,iWidth,iHeight)
{
  var iTop = (window.screen.availHeight-30-iHeight)/2;       //获得窗口的垂直位置;
  var iLeft = (window.screen.availWidth-10-iWidth)/2;           //获得窗口的水平位置;
window.open(url,name,'height='+iHeight+',innerHeight='+iHeight+',width='+iWidth+',innerWidth='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,status=no,scrollbars=no,resizable=no');
  //window.open(url,name,'height='+iHeight+',width='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,scrollbars=yes,resizeable=yes,location=no,status=yes');
}
function openwindowscroll(url,name,iWidth,iHeight)
{
  var iTop = (window.screen.availHeight-30-iHeight)/2;       //获得窗口的垂直位置;
  var iLeft = (window.screen.availWidth-10-iWidth)/2;           //获得窗口的水平位置;
window.open(url,name,'height='+iHeight+',innerHeight='+iHeight+',width='+iWidth+',innerWidth='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,status=no,scrollbars=yes,resizable=yes');
  //window.open(url,name,'height='+iHeight+',width='+iWidth+',top='+iTop+',left='+iLeft+',toolbar=no,menubar=no,scrollbars=yes,resizeable=yes,location=no,status=yes');
}

        function ___doPostBack(eventTarget, eventArgument)
        {
        var theform = document.forms['form1'];
        if (!theform)
        {
        theform = document.form1;
        }
        theform.__EVENTTARGET.value = eventTarget ;
        theform.__EVENTARGUMENT.value = eventArgument;
        theform.submit();
        }
   function openWindows(url, width, heigth)
   {
        var res=window.showModalDialog(url,window,"status:false;resizable:yes;dialogWidth:"+width+"px;dialogHeight:"+heigth+"px");
        if(res=="pleasefresh")
        {
         refresh();
        }
   }

在前台调用该函数:

   function OpenWindow()
   {

     var xn=document .getElementById ("ddlstXn");
     var xq=document .getElementById ("ddlstXq");
     var bh=document .getElementById ("txtBh");
     if(xn.selectedIndex==0||xq.selectedIndex==0||bh.value.length==0)
     {
        alert ("请输入学年+学期+班号");
        return false;
     }
     else
     {
        openwindow("CourseGradeRPT.aspx?xn="+xn.value+"&xq="+xq.value+"&bh="+bh.value+"", null ,900,600);
     }

   }

<asp:button  CssClass="bt_query"  text ="  综合查询" id="btnAllQueryGrade"  runat="server"  OnClientClick="OpenWindow();" />

--------------------------------------------------------------------------------------------------------------------------------------
在后台调用前台js函数:

function OpenWindowPrint(url)
   {
       openwindow(url ,null,800,600);
   }

1.string url = "GradeQueryClassRPT.aspx?xn=" + this.hidXn.Value + "&xq=" + this.hidXq.Value + "&bh=" + this.hidBh.Value+"&kc="+Server.UrlEncode(this.ddlstCourseCode.SelectedItem.Text);
Page.ClientScript.RegisterStartupScript(this.GetType(), "", " <script type='text/JavaScript'>OpenWindowPrint('" + url + "'); </script>");

2.Response.Write(" <script type='text/JavaScript'>window.open('" + url + "'); </script>");//按钮会变样

3.Page.ClientScript.RegisterStartupScript(this.GetType(), "", " <script type='text/JavaScript'>window.open('" + url + "'); </script>");

.hidBh.Value;
string url=" <script type='text/JavaScript'>OpenWindowPrint('" + urllink + "'); </script> "

this.btnOpen.Attributes.Add("onclick", OnAddClientClick);       //放在pageload里面

弹出模式对话框

/// <param name="page">要执行的页面对象</param>
        /// <param name="URL">要打开的页面地址</param>
        /// <param name="width">宽</param>
        /// <param name="height">高</param>
        public static string Fpage_f_win_opendialog_returnvalue(System.Web.UI.Page page, string URL, int width, int height)
        {
            string js2 = "javascript:";
            js2 += string.Format("res=window.showModalDialog(\"{0}\",window,\"status:no;resizable:no;dialogWidth:{1}px;dialogHeight:{2}px\");", URL, width.ToString(), height.ToString());
            js2 += "if (res==\"pleasefresh\")" + " {" + " refresh();" + "}";
            //js2 += string.Format("res=window.showModalDialog(\"{0}\",window,\"status:false;resizable:yes;dialogWidth:{1}px;dialogHeight:{2}px\");", URL, width.ToString(), height.ToString());
            return js2;
            //page.RegisterClientScriptBlock("can", js2);
        }

Onclick事件字符串
string OnAddClientClick = CommonPage.Fpage_f_win_opendialog_returnvalue(this.Page, "TeacherAdd.aspx", 850, 600);
//绑定新增按钮Onclick
this.btnAdd.Attributes.Add("onclick", OnAddClientClick);
