I have declared a JSON Object and added some key value pair in that like:
var obj = {};
并在其中添加了一些数据，如下所示:
obj = {
"1":"aa",
"2":"bb"
};
但我想在同一个对象中添加更多的键值对，如果我添加与上述相同的键值对，那么它将替换旧的键值对.那么，有谁能告诉我如何在同一个JSON对象(即obj)中添加数据.

Could you do the following:
obj = {
"1":"aa",
"2":"bb"
};
var newNum = "3";
var newVal = "cc";
obj[newNum] = newVal;
alert(obj["3"]); // this would alert 'cc'
