Question

我想从 JSON 数组中获取 key ？这是我的 JSON 数组

****JAVASCRIPT****
var employees = [
                 { "firstName":"John" , "lastName":"Doe" }, 
                 { "firstName":"Anna" , "lastName":"Smith" }, 
                 { "firstName":"Peter" , "lastName": "Jones" }

试试这个:

http://jsfiddle.net/NJMyD/1072/

var employees = '[{"firstName":"John","lastName":"Doe" },{"firstName":"Anna","lastName":"Smith" },{"firstName":"Peter","lastName":"Jones"}]';

var myData = JSON.parse(employees);

$(document).ready(function() {
    $.each(myData, function() {
        $('<li>' + this.firstName + ' ' + this.lastName + '</li>').appendTo("#groups");
    });
});
