JSON到对象数组，并向每个对象添加项目

Question

I am trying to retrieve data from a JSON file and creating an array of objects (works fine), but I also want to add an item to each object in the array while doing so.

This is my code:

var linklist = [];
$.getJSON('links.json').success(function (json) {
        $.each(json, function(i, obj) {
            linklist.push(obj);
            $(obj).extend({
                status:'Downloaded'
            });
        });
        })

If I try to output data in status, I get 'undefined' as a value.

Do this.

var linklist = [];
$.getJSON('links.json').success(function (json) {
    $.each(json, function(i, obj) {

        // add status property to current object
        obj.status = 'Downloaded';

        // add updated object to array
        linklist.push(obj)

    });
});
