JavaScript javascript regular expression to replace Math.cos trouble javascript regular expression tester,javascript regular expression match,javascript regular

I want to replace some math functions with Math.sin. This is what I've tried. I expect the results to be that Math.cos would be replaced by Math.sin

  re=/[Math\.cos|Math\.tan]/g;
  s="Math.cos(0)+Math.cos(0)";
  s=s.replace(re,"Math.sin");
  alert(s);

The result I would expect would be Math.sin(0)+Math.sin(0) instead it is

Math.sinMath.sinMath.sinMath.sinMath.sinMath.sinMath.sinMath.sin(0)+Math.sinMath.sinMath.sinMath.sinMath.sinMath.sinMath.sinMath.sin(0)

I'm not sure what to try to fix the code.

Answer:1

The square brackets radically change the meaning of your regular expression. Get rid of them.

re = /Math\.cos|Math\.tan/g;
Answer:2
