<!DOCTYPE HTML><HTML><Head><MetaCharSet= "Utf-8"/><Metaname= "Author"content= "http://www.softwhy.com/" /><title>Onblur and onfocus events-Ant Tribe</title><styletype= "Text/css">Li{Height:30px;List-style:None;font-size:12px;}Li input{width:120px;Height:15px;}</style><Scripttype= "Text/javascript">functionFocush () { This. Style.backgroundcolor="#CCC"; This. Style.color="Green";}functionBlurh () { This. Style.backgroundcolor="Red"; This. Style.color="Yellow";} Window.onload=function(){ varUserName=document.getElementById ("UserName"); varPW=document.getElementById ("PW"); Username.onfocus=Focush; Username.onblur=Blurh; Pw.onfocus=Focush; Pw.onblur=Blurh;}</Script></Head><Body><Div> <ul> <Li>Name:<inputtype= "text"ID= "UserName" /></Li> <Li>Password:<inputtype= "Password"ID= "PW" /></Li> </ul></Div></Body></HTML>
