creating list of objects in Javascript

Is it possible to do create a list of your own objects in Javascript? This is the type of data I want to store :

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

最佳答案

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);

动态生成对象列表

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

这里有一个工作示例 < a href = “ http://jsfiddle.net/b9f6Q/2/”rel = “ norefrer”> http://jsfiddle.net/b9f6q/2/ 参见控制台输出

也许你可以创建一个这样的数组:

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的回答，但改用 .map:

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

所以，我习惯了

var nameOfList = new List("objectName", "objectName", "objectName")

This is how it works for me but might be different for you, I recommend to watch some Unity Tutorials on the Scripting API.

实例化数组

  list = new Array()

将未定义的值推送到列表

    var text = list.forEach(function(currentValue, currentIndex, listObj) {
if(currentValue.text !== undefined)
{list.push(currentValue.text)}
});
