Character	Description
	A backslash causes a specific character to be matched. Remember to escape backslashes. For example: Copy Code     match("ab$cd","ab$cd");    //returns 0     match("ab$cd","ab$cd");   //returns 0 - the backslash is not escaped     match("ab\$cd","ab$cd");  //returns 1 - the backslash and dollar sign are escaped
< or ^	A 'less than'(<) sign or a circumflex (^) at the start of an expression is used to match the start of a line. For example: 以什么打头的 Copy Code     match("<abc","abcdef"); //returns 1     match("<abc","defabc"); //returns 0     match("^abc","abcdef"); //returns 1     match("^abc","defabc"); //returns 0
>	A 'greater than'(>) sign at the end of the expression is used to match the end of a line. For example: 以什么结尾 Copy Code     match("abc>","abcdef"); //returns 0     match("abc>","defabc"); //returns 1
? or .	A question mark (?) or a full stop (.) will match any character. For example: Copy Code通配符     match("abc.def","abc#def"); //returns 1     match("colou?r","colouXr"); //returns 1
:a	Sets the match to letters. For example: 字母 Copy Code     match("ab:acd","ab#cd");   //returns 0     match("ab:acd","abxyzcd"); //returns 0     match("ab:acd","abxcd");   //returns 1
:d	Sets the match to numeric characters. For example: 数字 Copy Code     match("ab:dcd","ab3cd");   //returns 1     match("ab:dcd","ab123cd"); //returns 0     match("ab:dcd","abcd");    //returns 0
:n	Sets the match to alphanumeric characters. For example: 数字或字符 Copy Code     match("ab:ncd","ab%cd"); //returns 0     match("ab:ncd","ab9cd"); //returns 1     match("ab:ncd","abXcd"); //returns 1
:SPACE	Where SPACE is the character ' '. Sets the match to blanks, tabulations, and control characters such as Enter (new line). For example: 空格，表格，控制符（回车） Copy Code     match("ab: cd","ab cd");   //returns 1     match("ab: cd","ab cd");  //returns 1     match("ab: cd","ab cd");  //returns 1     match("ab: cd","ab   cd"); //returns 0 - only the first space is matched
*	An expression followed by an asterisk requires a match for none, one, or more occurrences of the preceding expression. For example: 全部由*前的字符串中的没有，一个，多个组成 Copy Code     match("abc*d","abd");    //returns 1     match("abc*d","abcd");   //returns 1     match("abc*d","abcccd"); //returns 1     match("abc*d","abxd");   //returns 0
+	An expression followed by a plus (+) sign requires a match for one or more occurrences of the preceding expression. For example: 全部由*前的字符串中的一个，多个组成 Copy Code     match("abc+d","abd");    //returns 0     match("abc+d","abcd");   //returns 1     match("abc+d","abcccd"); //returns 1     match("abc+d","abxd");   //returns 0
-	An expression followed by a minus (-) sign requires a match for one or no occurrences of the preceding expression. Basically, the preceding expression is optional. For example: 全部由*前的字符串中的没有，一个组成 Copy Code     match("colou-r","color");  //returns 1     match("colou-r","colour"); //returns 1
[]	Matches a single character with any character contained within the brackets.A range of characters can be specified by two characters separated by '-' (minus). For example, "[a-z]" matches all letters between a and z, [0-9] matches a digit, [0-9a-f] matches a hexadecimal digit. 字符串范围 Copy Code     match("[abc]","apple");   //returns 1 - matches the 'a' in apple     match("[abc]","kiwi");    //returns 0 - kiwi does not contain an a, b, or c     match("gr[ae]y","grey");  //returns 1 - also matches "gray"     match("gr[ae]y","graey"); //returns 0 - only one character between "gr" and "y" is matched.
[^]	If the first character in a text within square brackets is a circumflex (^), the expression matches all characters except those contained within the brackets. 不包括字符串范围 Copy Code     match("[^bc]at","bat"); //returns 0     match("[^bc]at","hat"); //returns 1     match("[^abc]","bat");  //returns 1 - anything but a, b, or c is matched. The t is matched
