javascript - find the greatest number in string and its index -

Okay, my thirst for terrible oneliners is not exhausted yet ..

I have < / P>

  var a = "2: 3: 9: 5";  

I want to find the largest number and its index

In this case: 9 and index 2 .

What is the complex and terrible way to do this?

I tried:

  var _number = Math.max.apply (Math, a.split (':'));  

try it

  var a = "2 : 3: 9: 5 "; Var arr = a.split (":"); Var max = Math.max.apply (empty, arr); Var index = arr.indexOf (max.toString ());
