//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,''))"//消除图像工具栏
