Small iteration in javascript

Hey guys I have a slight problem.

Can somebody show me how I would be able to separate this string into a json formatted data?

one:apple;two:orange;three:bananna;four:pears

To look like this

{
  one: apple,
  two: orange,
  three: bananna,
  four: pears
}

Use Array#forEach over String#split

var str = "one:apple;two:orange;three:bananna;four:pears";
var obj = {};
str.split(';').forEach(function(el) {
  var x = el.split(':');
  obj[x[0]] = x[1];
});
console.log(obj);

Or using Array#reduce

The comma operator evaluates each of its operands (from left to right) and returns the value of the last operand.

var str = "one:apple;two:orange;three:bananna;four:pears";
var obj = str.split(';').reduce(function(a, b) {
  var x = b.split(':');
  return a[x[0]] = x[1], a;
}, {});
console.log(obj);

DEMO

var str = "one:apple;two:orange;three:bananna;four:pears";
var arr = str.split(';'), obj = {}, i = 0;
for(; i < arr.length; i++){
  var x = arr[i].split(':');
  obj[x[0]] = x[1]
};
console.log(obj);
x = null;

You can use regex to do this.

var str = "one:apple;two:orange;three:bananna;four:pears"

var obj = '{"'+ str.replace(/;/g, ',').replace(/[:+,]/g, '"$&"') + '"}'
console.log(JSON.parse(obj))
