基于javascript的在火狐里面强制换行字符

效果演示代码:
<！DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>firefox-break-word</title> <style type="text/css"> <！[CDATA[/*> </style> </head> <body>If there were less sympathy in the world, there would be less trouble in the world. （ O. Wilde ）<script> function toBreakWord（intLen）{ var obj=document.getElementById（"ff"）; var strContent=obj.innerHTML; var strTemp=""; while（strContent.length>intLen）{ strTemp+=strContent.substr（0,intLen）+""; strContent=strContent.substr（intLen,strContent.length）; } strTemp+=""+strContent; obj.innerHTML=strTemp; } if（document.getElementById && ！document.all） toBreakWord（37） </script> </body> </html>
[Ctrl+A 全选注:如需引入外部Js需刷新才能执行]
