Javascript Split String On Every Other Symbol

I have a string in the form of ':x1:y1:x2:y2x3:y3:...:' and the keys and values Xn and Yn are arbitrary values so i can't use the length of the strings i would like to split this

Solution 1:

Try this:

var obj = (function(str){
  var result = {};

  str.replace(/([^\:]+)\:([^\:]+)/g, function($0, $1, $2){
    result[$1] = $2;
  });  

  return result;
})('x1:y1:x2:y2:x3:y3');
