// Regular Expression matching
Regular Expression matching Chinese characters: [\ u4e00-\ u9fa5]
Match double-byte characters (including Chinese characters): [^ \ x00-\ xFF]
Regular Expression for matching empty rows: \ n [\ s |] * \ r
Regular Expressions matching HTML tags:/<(. *)>. * <\/\ 1> | <(. *) \/>/
Regular Expressions matching spaces at the beginning and end: (^ \ s *) | (\ s * $) (TRIM functions like VBScript)
The regular expression matching the email address: \ W + ([-+.] \ W +) * @ \ W + ([-.] \ W + )*\. \ W + ([-.] \ W + )*
The regular expression matching the URL: http: // ([\ W-] + \.) + [\ W-] + (/[\ W -./? % & =] *)?
The following is an example:
Use regular expressions to restrict text box input in a webpage form:
Use a regular expression to restrict Chinese characters only: onkeyup = "value = value. Replace (/[^ \ u4e00-\ u9fa5]/g ,'')"
Onbeforepaste = "clipboardData. setdata ('text', clipboardData. getdata ('text'). Replace (/[^ \ u4e00-\ u9fa5]/g ,''))"

1. Use a regular expression to limit that only full-width characters can be entered: onkeyup = "value = value. Replace (/[^ \ uff00-\ Uffff]/g ,'')"
Onbeforepaste = "clipboardData. setdata ('text', clipboardData. getdata ('text'). Replace (/[^ \ uff00-\ Uffff]/g ,''))"

2. Use a regular expression to limit that only numbers can be entered: onkeyup = "value = value. Replace (/[^ \ D]/g ,'')
"Onbeforepaste =" clipboardData. setdata ('text', clipboardData. getdata ('text'). Replace (/[^ \ D]/g ,''))"

3. Use a regular expression to limit that only numbers and English letters can be entered: onkeyup = "value = value. Replace (/[\ W]/g ,'')
"Onbeforepaste =" clipboardData. setdata ('text', clipboardData. getdata ('text'). Replace (/[^ \ D]/g ,''))"
