jquery creating two dimensional array
提问by Stephen S.
Edit: It appears I was a bit confused on what I was trying to accomplish. For those that took the time to explain this, thank you.
编辑：看来我对我想要完成的事情有点困惑。对于那些花时间解释这一点的人，谢谢。
I'm trying to create a two dimensional array in Jquery/Javascript. I've done a decent amount of searching, testing and more searching but i'm unable to find a solution that really makes sense to me. (it's been a very long week already....)
我正在尝试在 Jquery/Javascript 中创建一个二维数组。我已经做了大量的搜索、测试和更多的搜索，但我无法找到对我来说真正有意义的解决方案。（这已经是很长的一周了......）
Below is the desired format of the array.
以下是所需的数组格式。
{"product":[{"attribute":"value","attribute":"value"}]}

That's not a 2D array, but rather an object. Also, your product array contains only one object. I think you need something like this:
那不是一个二维数组，而是一个对象。此外，您的产品数组仅包含一个对象。我认为你需要这样的东西：
var obj = {};
obj.product = [];
for(var i=0; i < someObj.length; i++) {
obj.product.push[{"attribute": someObj[i]}]
}
This will produce an array inside the productproperty:
这将在product属性内生成一个数组：
{"product":[{"attribute":"value"}, {"attribute":"value"}]}

You can't create a two dimensional array in Javascript, arrays can only have one dimension. Jagged arrays, i.e. arrays of arrays, are used instead of two dimensional arrays.
您不能在 Javascript 中创建二维数组，数组只能有一个维度。锯齿状数组，即数组的数组，用于代替二维数组。
Example:
例子：
var a = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
];
The desired format that you show is neither a two dimensional array nor a jagged array, instead it's an object containing a property that is an array of objects. However, the object in the array has two properties with the same name, so I assume, you meant that as having two objects in the array:
您显示的所需格式既不是二维数组也不是锯齿状数组，而是一个包含对象数组属性的对象。但是，数组中的对象有两个同名的属性，所以我假设，你的意思是数组中有两个对象：
var o = {
product: [
{ attribute: "value" },
{ attribute: "value" }
]
};
You can create an object like that using a literal object like above, or you can create it by adding properties and array items afterwards:
您可以使用像上面这样的文字对象创建这样的对象，也可以通过添加属性和数组项来创建它：
var o = {};
o.product = [];
o.product.push({ attribute: "value" });
o.product.push({ attribute: "value" });

$(".adddiv").each(function(){
tasks = [];
$(".subtasktask"+len).each(function() {
var raw = $(".subtasktask"+len).children().size();
for(var l =0;l
datas.push(milestone);
alert("now show json milestone array : ");
alert(milestone.month + ":" + milestone.title +":" + milestone.task. );
len++
});

This is my solution.
这是我的解决方案。
var optionArr = []
optionArr = {"product": [{"id":1, "name":"abc"}, {"name":"value"}]}
var data = optionArr['product'][0]['name']
alert(data)

Try this:
尝试这个：
{"product":[ [{"attribute":"value"},{"attribute":"value"}]]}
