//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,'))"
