javascript - how to create this type of JSON array dynamically -


hardcoded:

    var imageinfocols = [{         "location" : "https://dl.dropboxusercontent.com/u/42060851/imagegrid/1.jpg",         "title" : "movie 1"     }, {         "location" : "https://dl.dropboxusercontent.com/u/42060851/imagegrid/2.jpg",         "title" : "movie 2"     }, {         "location" : "https://dl.dropboxusercontent.com/u/42060851/imagegrid/3.jpg",         "title" : "movie 3"     } ];

each item has 2 properties, location , title.

i want create object 2 properties , push onto json array. best way using loop?

var objectarray = []; var field1 = 'location'; // dynamically set field name var field2 = 'title'; // same second field var length = 3;  (var = 0; < length; i++) {     object = {};      // javascript object properties can acccessed     // , set dynamically index notation     object[field1] = 'https://dl.dropboxusercontent.com/u/42060851/imagegrid/' + + '.jpg';     object[field2] = 'movie ' + i;      objectarray.push(object); }; // json actual json string var json = json.stringify(objectarray);
