//正则匹配
匹配中文字符的正则表达式： [\一-\龥]
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="val=val.replace(/[^\一-\龥]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\一-\龥]/g,''))"
1.用正则表达式限制只能输入全角字符： onkeyup="val=val.replace(/[^\?-\?]/g,'')" onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\?-\?]/g,''))"
2.用正则表达式限制只能输入数字：onkeyup="val=val.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="val=val.replace(/[\W]/g,'') "onbeforepaste="clipboardData.setData('text',clipboardData.getData('text').replace(/[^\d]/g,''))"
