//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：-./?%=]*)?
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,))
