在javascript中设置焦点 [英] setting focus in javascript

问题描述

Hiii全部，

请查看以下javascript:

Hiii All,

Please have a look at the following javascript:

if((document.getElementById("TextBox1").value == "") || (document.getElementById("TextBox1").value == "__/__/____"))
   {
            alert ( "Invalid Date" );
            document.getElementById("TextBox1").value="__/__/____";
            document.form1.TextBox1.focus();
            return false;
    }

在这里，我针对TextBox1的textchanged事件及其工作情况提供了此脚本，但是当我们按Tab键时，它不关注TextBox1..



问候，

here, I am giving this script on textchanged event of TextBox1 and its working but its not focusing on TextBox1 when we press tab ..



Regards,

推荐答案

尝试一下...

try this...

document.getElementById("<%=txtName.ClientID%>").focus();

请参见此 [

var id = document.getElementById('TextBox1');
if((id.value == "") || (id.value == "__/__/____"))
   {
            alert ( "Invalid Date" );
            id.value="__/__/____";
            id.focus();
            return false;
   }
