在Javascript中创建对象列表

Question

是否可以创建list自己的对象Javascript？这是我想要存储的数据类型:

Date : 12/1/2011   Reading : 3   ID : 20055    
Date : 13/1/2011   Reading : 5   ID : 20053    
Date : 14/1/2011   Reading : 6   ID : 45652

Answer 1

var list = [
    { date: '12/1/2011', reading: 3, id: 20055 },
    { date: '13/1/2011', reading: 5, id: 20053 },
    { date: '14/1/2011', reading: 6, id: 45652 }
];

然后访问它:

alert(list[1].date);

Answer 2

动态构建对象列表

var listOfObjects = [];
var a = ["car", "bike", "scooter"];
a.forEach(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    listOfObjects.push(singleObj);
});

这是一个工作示例http://jsfiddle.net/b9f6Q/2/ 请参阅控制台输出

Answer 3

也许你可以像这样创建一个数组:

     var myList = new Array();
     myList.push('Hello');
     myList.push('bye');

     for (var i = 0; i < myList .length; i ++ ){
        window.console.log(myList[i]);
     }

关闭tbradley22的答案,但.map改为使用:

var a = ["car", "bike", "scooter"];
a.map(function(entry) {
    var singleObj = {};
    singleObj['type'] = 'vehicle';
    singleObj['value'] = entry;
    return singleObj;
});
