该页面顶部和左边有用户自定义控件，其中左边控件是用于查询的，希望当在左侧输入查询条件后直接回车即响应“查询”按钮，但每次响应的却是顶部控件的第一个按钮。
我在该页面使用JAVASCRIPT：
function document.onkeydown()
{
var e=event.srcElement;
if(event.keyCode==13)
{
document.getElementById( "LeftMenu_btn_inquery ").click();
return false;
}
}
“LeftMenu_btn_inquery”是左侧控件“查询”按钮（服务器控件）的clientid，试过直接使用其id，也不对。
希望大家帮帮我吧~~~“查询”不和回车联系，客户用起来总感觉不流畅啊~~
------解决方案--------------------------------------------------------
try:
function document.onkeydown()
{
var ctlId = " <%=LeftMenu_btn_inquery.ClientID%> ";
var e=event.srcElement;
if(event.keyCode==13)
{
document.getElementById(ctlId ).click();
return false;
}
}
