Regex for mustache-style double braces?

rated 0 times [ 14] [ 3] / answers: 1 / hits: 18684 / 11 Years ago, tue, march 19, 2013, 12:00:00

I'm using Mustache-style tags inside of AngularJS. What's the best regex to use to return an array of just the text inside the mustache braces?

Sample data:

This could {{be }} a {{ string.with.dots_and_underscores }} of {{ mustache_style}} words which {{could}} be pulled.

Expected output:

['be','string.with.dots_and_underscores','mustache_style','could']

If you use a global search with .match, JavaScript won't give the capture groups in its array output. As such, you need to do it twice: Once to find the {{...}} pairs, then again to extract the names from within them:

str.match(/{{s*[w.]+s*}}/g)

   .map(function(x) { return x.match(/[w.]+/)[0]; });
