优点：兼容性很好，而且俺觉得不应该有什么拦截工具可以拦截下来
优点：代码非常短
缺点：必须在页面点击后才会弹出
demo:
运行代码框
<head>
<style>
#link001 img { border-style:none; }
</style>
<script>
function cancelOpenNew(){
if(!window.event){setTimeout(cancelOpenNewA,1000);return;}
var obj=window.event.srcElement;
if(!obj)return;
if(!obj.tagName)return;
if(String(obj.tagName).match(/input|select|option|textarea/i))return;
setTimeout(cancelOpenNewA,1000);
}
function cancelOpenNewA(){document.body.appendChild(document.getElementById('MainDiv001'));}
</script>
</head>
<body>
<a href="http://www.blueidea.com" target="_blank" onclick="cancelOpenNew();" id="link001" style="color:black; text-decoration:none; cursor:default; display:block;" hidefocus="true">
<div id="MainDiv001">

I try to put something here.<br>
<input />

<ol>
<li><img src="http://www.blueidea.com/articleimg/bbsimg/closedb.gif"/> And this</li>
<li><img src="http://www.blueidea.com/articleimg/bbsimg/closed.gif"/> is a list</li>

[Ctrl+A 全部选择 提示：你可先修改部分代码，再按运行]
说明：
1.为了保证页面中的 img 不会出现丑陋的边框
<style>
#link001 img { border-style:none; }
</style>
2.保证窗口只弹出一次
<script>
function cancelOpenNew(){
if(!window.event){setTimeout(cancelOpenNewA,1000);return;}
var obj=window.event.srcElement;
if(!obj)return;
if(!obj.tagName)return;
if(String(obj.tagName).match(/input|select|option|textarea/i))return;
setTimeout(cancelOpenNewA,1000);
}
function cancelOpenNewA(){document.body.appendChild(document.getElementById('MainDiv001'));}
</script>
3.这个结构是弹窗的根本－－－其实只不过是个 target="_blank" 的链接而已，拦截程序要是连这个都要拦，俺也无话可说
<body>
<a href="http://www.blueidea.com" target="_blank" onclick="cancelOpenNew();" id="link001" style="color:black; text-decoration:none; cursor:default; display:block;" hidefocus="true">
<div id="MainDiv001">
4.千万不要忘记在页面结束的地方加上:
</div>
</a>
</body>
