Regular match

Regular expressions that match Chinese characters: [\U4E00-\U9FA5]
Match double-byte characters (including kanji): [\x00-\xff]
Regular expression that matches a blank line: \n[\s|]\ r
Regular expression matching HTML markup:/< (. *);.<\/\1>|< (. *) \/>/
Regular expression matching the leading and trailing spaces: (\s)| (\s$) (Trim function like VBScript)
Regular expression matching email address: \w+ ([-+.] \w+)@\w+ ([-.] \w+). \w+ ([-.] \w+)
Regular expression matching URL URL:/http ([\w-]+.) +[\w-]+ (/[\w-./?%&=])?
Here is an example:
Use regular expressions to restrict the entry of text boxes in Web Forms:
Use regular expression restrictions to enter only Chinese: onkeyup= "value=value.replace (/[\u4e00-\u9fa5]/g,") "Onbeforepaste=" Clipboarddata.setdata (' text ' , Clipboarddata.getdata (' text '). Replace (/[\u4e00-\u9fa5]/g, ')) "
1. Restrict input of full-width characters with regular expressions: onkeyup= "Value=value.replace (/[\uff00-\uffff]/g,") "Onbeforepaste=" Clipboarddata.setdata (' Text ', Clipboarddata.getdata (' text '). Replace (/[\uff00-\uffff]/g, ')) "
2. Use regular expression restrictions to enter only numbers: onkeyup= "Value=value.replace (/[\d]/g,") "Onbeforepaste=" Clipboarddata.setdata (' text ', Clipboarddata.getdata (' text '). Replace (/[\d]/g, ')) "
3. Use regular expression restrictions to enter only numbers and English: onkeyup= "Value=value.replace (/[\w]/g,") "Onbeforepaste=" Clipboarddata.setdata (' text ', Clipboarddata.getdata (' text '). Replace (/[^\d]/g, ')) "
