JavaScript making an array of key value object from a string

Question

I have a string like this

var information = 'name:ozil,age:22,gender:male,location:123 street';

I want to make an array of key value object like this

var informationList=[
    {
       'key':'name',
       'value':'ozil'
    },
    {
       'key':'gender',
       'value':'male'
    },
    {
       'key':'location',
       'value':'123 street'
    },

]

And what have tried so far? SO is not a code-request community. — Yoshi, Nov 25 '14 at 11:46
Naive approach: `'name:ozil,age:22,gender:male,location:123 street'.split(',').map(function(el) { var p = el.split(':'); return {key: p[0], value: p[1]}; })` — dfsq, Nov 25 '14 at 11:49

Using split and map:

var information = 'name:ozil,age:22,gender:male,location:123 street',
    result = information.split(',').map(function(item){
      var arr = item.split(':');
      
      return {
        key: arr[0],
        value: arr[1]
      }
    });


document.write(JSON.stringify(result));

You can try this:

var list = [];
var pairs = information.split(',');
for (var i = 0; i < pairs.length; i++) {
    var p = pairs[i].split(':');
    list.push({
        key: p[0],
        value: p[1]
    });
}

This should do it:

var input = "name:ozil,age:22,gender:male,location:123 street";
var temp = input.split(",");
var result = [];
for(var i=0; i < temp.length; i++) {
    var temp2 = temp[i].split(":");
    result.push({key:temp2[0], value:temp2[1]});
}
console.log(result);

result now contains what you specified.
