prototypejs - How do I create a Hash from an Array using the Prototype JavaScript framewor? -

I have an array ['red', 'green', 'blue']

  {' red ': true'  

prototype What is the best way to achieve the goal of using it?

Just rearrange the array and then create hash:

  Obj = {}; (Var i = 0, l = colors.length; i & lt; l; i ++) {obj [color [i]] = true; } Has hash = new hash (obje);  

You can also create a new hash object from the beginning:

  var hash = new hash (); (Var i = 0, l = colors.length; i & lt; l; i ++) {hash.Set (color [i] is true); }  

I recommend
