火狐与IE浏览器文本兼容技巧：innerText vs innerHTML

这是其中一个，我觉得很不错的。
原理:采用innerText 或者 innerHTML 
<script language=”javascript”> 
var stock_code = stockcode.innerText; 
var stock_code = stockcode.innerHTML; 
</script> 
<div id="stockcode" style="display:none"> 
test 
</div> 

innerText 跟 innerHTML是两个非DOM标准的方法
其区别如图所示：
（图中应该为innerText）

在IE中 innerText 跟 inner HTML 两个方法都能正常运行
但是FF里面的innerText不可用，但是有一个替代方法: textContent
IE: oDiv.innerText = aString; oDiv.innerHTML = aString;
FF: oDiv.textContent = aString; oDiv.innerHTML = aString;
Ajax in action 的作者之一Eric 用正则表达式 实现了 一个兼容方法，比较有趣
Hope this helps
A little smirk 
One day a secretary is leaving on her lunch break, and she notices her boss standing in front of a shredder with a clueless look on his face. The secretary walks up to him and asks if he needs help. 
"Yes!" he says looking and sounding relieved, "This is very important." 
Glad to help, she turns the shredder on and inserts the paper. Then her boss says, "Thanks, I only need one copy." 
Create function like innerText 
As you may have figured out innerText is IE only. That means that browsers like Mozilla, Firefox, and Netscape will return undefined. If you do not know what innerText does, it strips out all of the tags so you only see the text. 
For example, if a div contains the HTML <span id='span1'>Eric</span>, innerHTML would return <span id='span1'>Eric</span> while innerText will return Eric. 
Now to make innerHTML act the same we need to use some regular expressions with the strings replace() method. 
Now the basic pattern we need to match is or or or 
Now the regular expression we need to use is /<\/?[^>]+>/gi
