javascript function inArray

Question

I need a javascript function that can take in a string and an array, and return true if that string is in the array..

 function inArray(str, arr){
   ...
 }
         


        

Answer 1

You could just make an array prototype function ala:

Array.prototype.hasValue = function(value) {
  var i;
  for (i=0; i

Note the use of '===' instead of '==' you could change that if you need less specific matching... Otherwise [3].hasValue('3') will return false.
