dynamically build list of objects
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);
});
here's a working example http://jsfiddle.net/b9f6Q/2/see console for output

Maybe you can create an array like this:
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]);
}

Going off of tbradley22's answer, but using .mapinstead:
离开 tbradley22 的答案，而是使用.map：
var a = ["car", "bike", "scooter"];
a.map(function(entry) {
var singleObj = {};
singleObj['type'] = 'vehicle';
singleObj['value'] = entry;
return singleObj;
});

So, I'm used to use
所以，我习惯使用
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.
这对我来说是这样的，但对你来说可能会有所不同，我建议观看一些关于脚本 API 的 Unity 教程。
