捕获两个特殊字符之间的单词

Question

I have a string like this:

"some string, some $special$ string, some string, some string, some $special$ string,..."

I need to capture all words between two $ notation and put words inside <code></code> tag. The result of above string should be this:

"some string, some <code>special</code> string, some string, some string, some <code>special</code> string,..."

How can I do this via javascript or jquery?

Answer 1

您可以使用替换功能和简单的正则表达式：

'your text ...'.replace(/\$(.+?)\$/g, '<code>$1</code>')

Answer 2

Use regex in replace as follow:

var myStr = "some string, some $special$ string, some string, some string, some $NotSospecial$ string,...";

myStr = myStr.replace(/\$(\w+)\$/g, '<code>$1</code>');

1. \\$ : This will escape $ for exact match
2. (\\w+) : Capturing group: will match any characters any no. of time
3. g : Global match. to continue even after first match
4. $1 : The match from capturing group

Answer 3

Using regex, and an overload of string.replace which takes a regular expression and a replacer function:

 var re = /\\$(.*?)\\$/g; var input = "some string, some $special$ string, some string, some string, some $special$ string,..."; var result = input.replace(re,function(match,g1){ return "<code>" + g1 + "</code>"; }); alert(result);
