<script type="text/javascript"> 
function click1(obj) 
{ 
alert(obj.innerHTML); 
} 
</script> 
</head> 

<body> 
<div onclick="click1(this)" style="cursor:pointer">點(diǎn)擊我吧</div> 
</body> 
</html> 

this即div的上下文，點(diǎn)擊后會(huì)彈出<div>之間的內(nèi)容。
2.鼠標(biāo)移動(dòng)

復(fù)制代碼代碼如下:

<script type="text/javascript"> 
function mouse1(obj) 
{ 
obj.style.color = "#f00"; 
obj.style.fontSize = "18px" 
} 
function mouse2(obj) 
{ 
obj.style.color = "#000"; 
obj.style.fontSize = "16px" 
} 
</script> 
</head> 

<body> 
<div onmouseover="mouse1(this)" onmouseout="mouse2(this)">移動(dòng)到這兒</div> 
</body> 
</html> 

onmouseover鼠標(biāo)放到那兒時(shí)，會(huì)把字體變大，字體成為紅色，離開(kāi)時(shí)字體和顏色恢復(fù)。
3.with用法

復(fù)制代碼代碼如下:

 
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<meta name="Keywords" content=""> 
<meta name="Description" content=""> 

<script type="text/javascript"> 
with(document) 
{ 
write("niujiabin"+"<br/>"); 
write("maybe"+"<br/>"); 
write("gossip"+"<br/>"); 
} 
</script> 
</head> 
<body> 
</body> 
</html> 

效果與如下相同
