javascript - Test if string contains brackets with integer in it -

i want test if string in javascript contains normal brackets integer in it

var str="(12) test"; var pat=/(([\d]+))/; if (pat.test(str)) alert("true");

works fine, returns true when string looks this

var str="12) test"; var str="(12 test";

which should homecoming false.

escape brackets \:

/\([\d]+\)/.test(str);
