Question

If I have the following string:

mickey mouse WITH friend:goofy WITH pet:pluto

What is the best way in javascript to take that string and extract out all the “key:value” pairs into some object variable? The colon is the separator. Though I may or may not be able to guarantee the WITH will be there.

Answer 1

var array = str.match(/\w+\:\w+/g);

Then split each item in array using ":", to get the key value pairs.

Here is the code:

function getObject(str) {
  var ar = str.match(/\w+\:\w+/g);
  var outObj = {};
  for (var i=0; i < ar.length; i++) {
    var item = ar[i];
    var s = item.split(":");
    outObj[s[0]] = s[1];
  }
  return outObj;  
}
