//正则匹配 匹配中文字符的正则表达式： [/u4e00-/u9fa5]
匹配双字节字符(包括汉字在内)：[^/x00-/xff]
匹配空行的正则表达式：/n[/s| ]/r
匹配html标记的正则表达式：/< (.)> .< ///1> |< (.) //> /
匹配首尾空格的正则表达式：(^/s)|(/s$)（像vbscript那样的trim函数）
匹配email地址的正则表达式：/w+([-+.]/w+) /w+([-.]/w+)/./w+([-.]/w+)
匹配网址url的正则表达式：http://([/w-]+/.)+[/w-]+(/[/w- ./?& =])?
以下是例子：
利用正则表达式限制网页表单里的文本框输入内容：
用正则表达式限制只能输入中文：onkeyup=" value=value.replace(/[^/u4e00-/u9fa5]/g ' ' )" onbeforepaste=" clipboarddata.setdata(' text' clipboarddata.getdata(' text' ).replace(/[^/u4e00-/u9fa5]/g ' ' ))"
1.用正则表达式限制只能输入全角字符： onkeyup=" value=value.replace(/[^/uff00-/uffff]/g ' ' )" onbeforepaste=" clipboarddata.setdata(' text' clipboarddata.getdata(' text' ).replace(/[^/uff00-/uffff]/g ' ' ))"
2.用正则表达式限制只能输入数字：onkeyup=" value=value.replace(/[^/d]/g ' ' ) " onbeforepaste=" clipboarddata.setdata(' text' clipboarddata.getdata(' text' ).replace(/[^/d]/g ' ' ))"
3.用正则表达式限制只能输入数字和英文：onkeyup=" value=value.replace(/[/w]/g ' ' ) " onbeforepaste=" clipboarddata.setdata(' text' clipboarddata.getdata(' text' ).replace(/[^/d]/g ' ' ))"
