Javascript数组问题

Question

var data = [];
var id = 23;
var num = 12;
var dog_trialset = 15;
var cat_trialset = 23;

来自这里的问题

data.push({id:{num:num, dog_trialset:dog_trialset, cat_trialset:cat_trialset}});

ajax发布到php

[data] => Array
    (
        [0] => Array
            (
                [id] => Array
                    (
                        [num] => 12
                        [dog_trialset] => 15
                        [cat_trialset] => 34
                    )

            )

    )

我希望[id] => Array(...)能够[23] => Array(...);

您可以使用下标运算符将变量用作键：

var row = {};
row[id] = {num:num,dog_trialset:dog_trialset,cat_trialset:cat_trialset};
data.push(row);
