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：οnkeyup= "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： οnkeyup= "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：οnkeyup= "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：οnkeyup= "value=value.replace(/[/W]/g,'') "onbeforepaste= "clipboardData.setData('text',clipboardData.getData('text').replace(/[^/d]/g,''))"
