在java脚本中获取错误 [英] getting error in java script

问题描述

嗨我在javascript中得到以下错误：



Microsoft JScript运行时错误：'scrollLeft'为null或不是对象



只有在我将ClientIDMode =AutoID此属性添加到子页面指令时才会出现错误



这是脚本：

Hi i am getting below error in javascript:

Microsoft JScript runtime error: 'scrollLeft' is null or not an object

Error is getting only when I have added ClientIDMode="AutoID" this property to child page directive

this is the script:

window.moveTo(0, 0);
       window.resizeTo(screen.availWidth, screen.availHeight);
       var xPos, yPos;
       var prm = Sys.WebForms.PageRequestManager.getInstance();
       prm.add_beginRequest(BeginRequestHandler);
       prm.add_endRequest(EndRequestHandler);
       function BeginRequestHandler(sender, args) {
           xPos = $get('contentPanel').scrollLeft;
           yPos = $get('contentPanel').scrollTop;
       }
       function EndRequestHandler(sender, args) {
           $get('contentPanel').scrollLeft = xPos;
           $get('contentPanel').scrollTop = yPos;
       }

请指导我解决此问题。

推荐答案

get（' contentPanel'）。scrollLeft;
yPos =

get('contentPanel').scrollLeft; yPos =

get（' contentPanel' ）.scrollTop;
}
function EndRequestHandler（sender，args）{

get('contentPanel').scrollTop; } function EndRequestHandler(sender, args) {

get（' contentPanel'）。scrollLeft = xPos;

get('contentPanel').scrollLeft = xPos;
