在下拉列表中传递多维数组值

Question

I'm creating an ajax function to retirieve product details from mongoDb

and the array structure is:

Array
(
   [PRD20160830063407] => Array
    (
        [_id] => PRD20160830063407
        [tpl] => Array
            (
                [ProductName] => Adidas Agro-Yellow,Gray
            )

    )

[PRD20160831104319] => Array
    (
        [_id] => PRD20160831104319
        [tpl] => Array
            (
                [ProductName] => sera xv001s
            )

    )

)

Need to pass _id, ProductName in a Select Box value and data part, I do not know how to retrieve the multidimensional array..

Appreciate for any helps. Thanks!

If I understand the question correctly (I'm not aware of the notation you used to show us the array), you're actually having problems with accessing the associative array because the data is not in array[0], array[1], etc. but in array[PRD20160830063407], etc; which means that you cannot iterate using the common for-loop.

You need Object.keys(array) to iterate over them.

var IDs = [];
Object.keys(array).forEach(key => {
    IDs.push(array[key]['_id']);
});
