But it still captures preceding comma.

No, it matches the preceding comma, but it doesn't capture it:

 var regex = /\\,([-+]?(\\d*[.])?\\d*)/g; var str = "testing,123"; var match = regex.exec(str); console.log("The match was : " + match[0]); // ",123" console.log("But the capture was: " + match[1]); // "123"
