// 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 Expression matching spaces at the beginning and end: (^ s *) | (S * $) (TRIM function like VBScript)
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:
You can only enter Chinese characters using regular expressions: onkeyup = "value = value. replace (/[^ u4E00-u9FA5]/g, '')" onbeforepaste = "clipboardData. setdata ('text', clipboardData. getdata ('text '). replace (/[^ u4E00-u9FA5]/g ,''))"

1. you can only enter the full-width characters: 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. you can only enter numbers and English letters using regular expressions: onkeyup = "value = value. replace (/[w]/g, '')" onbeforepaste = "clipboardData. setdata ('text', clipboardData. getdata ('text '). replace (/[^ d]/g ,''))"

// Special effects for entering and exiting the page

Go to the <meta http-equiv = "Page-Enter" content = "revealtrans (duration = x, transition = y)">

Launch page <meta http-equiv = "Page-Exit" content = "revealtrans (duration = x, transition = y)">

This is some special effects of page loading and calling. Duration indicates the duration of the special effect, in seconds. Transition indicates
Which special effect is used? The value ranges from 1 to 23:
0 rectangular narrowing
1. rectangular enlargement
2 rounded down
3. Circular Expansion
4. Refresh from bottom to top
Refresh from top to bottom
6-left-right refresh
7. right-to-left refresh
8 vertical blinds
9 horizontal blinds
10 misplaced horizontal blinds
11 misplaced vertical blinds
Spread
Refresh from around 13 to the center
14. Refresh from center to left
15.
16 up to the middle
17 bottom right to top left
18 top right to bottom left
19 upper left to lower right
20 bottom left to top right
21 horizontal bars
22 vertical bars
