Js regexp 变量以获取字符串中的所有匹配项

Question

There is the following code:

s.match(/\+[A-Za-z0-9_]+/);

I use it to get all Jade mixins from string. It works good for one Jade mixins in string ("+article"), but doesn't work for 2 mixins in string("+article +b") - it returns array with first item only. What did I do wrong? Thanks! Also it will be good to get array with values without plus!

Answer 1

Add global flag g in your regex

s.match(/\+[A-Za-z0-9_]+/g);

---

UPDATE : Demo with removed + symbol

 s = '+abc +4kk +ttt'; var res = s.match(/\\+[A-Za-z0-9_]+/g).map(function(v) { return v.substring(1) // get string after `+` }); document.write('<pre>' + JSON.stringify(res, null, 3) + '</pre>');

Or regex with captured group

 var s = '+abc +4kk +ttt'; var reg = /\\+([A-Za-z0-9_]+)/g; var matches, res = []; while (matches = reg.exec(s)) { res.push(matches[1]); // get captured group value } document.write('<pre>' + JSON.stringify(res, null, 3) + '</pre>');
