//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,''))"

//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,''))"
