我查看了sizzle代码并查看了一个定义.
var chunker = /((?:\((?:\([^()]+\)|[^()]+)+\)|\[(?:\[[^\[\]]*\]|['"][^'"]*['"]|[^\[\]'"]+)+\]|\\.|[^ >+~,(\[\\]+)+|[>+~])(\s*,\s*)?((?:.|\r|\n)*)/g,
我想知道如何找出这个正则表达式匹配的字符串？
解决方法
请参见
this article.多行正则表达式中的说明：
var chunker = /
(
(?:
# One or more sets of parentheses that contain a string,or another set of
parentheses with a string
\(
(?:
\([^()]+\)
|
[^()]+
)+
\)
|
# Or one or more sets of brackets that contain a string,or another set of
brackets with a string
\[
(?:
\[[^\[\]]*\]
|
['"][^'"]*['"]
|
[^\[\]'"]+
)+
\]
|
# Or a backslash followed by any character
\\.
|
# Or one or more of any except these characters: > +~,([\
[^ >+~,(\[\\]+
)+
# or any one of these characters: >+~
|
[>+~]
)
# followed by zero or one commas,which may be surrounded by whitespace
(\s*,\s*)?
# followed by zero or more of anything,including line endings
((?:.|\r|\n)*)
/g
此表达式包含三个匹配组：“已验证”选择器表达式,最终逗号以及之后的所有内容.它将在选择器上连续调用以将其分成几部分,有关详细信息,请参阅Sizzle构造函数.
