如何在JavaScript中将JSON数组转换为JSON对象 [英] How to convert json array to json object in javascript

问题描述

我有一个json数组，如下图所示:

I have a json array like in the below image:

JSon数组

我希望它是onyl json对象而不是数组.就像我做JSON.stringify一样，我得到了:[{"total_exec_qty":"286595","total_notional":"21820771.72","total_wt_arr_last_slp":"2.4364","total_num_ords":"1630","total_wt_ivwap_slp":"6.0969","total_wt_arr_slp":"1.7889","total_ord_qty":"576991"}]

I want it to be onyl json object and not array. Like when I do JSON.stringify I get this: [{"total_exec_qty":"286595","total_notional":"21820771.72","total_wt_arr_last_slp":"2.4364","total_num_ords":"1630","total_wt_ivwap_slp":"6.0969","total_wt_arr_slp":"1.7889","total_ord_qty":"576991"}]

但是我只想要这样:{"total_exec_qty":"286595","total_notional":"21820771.72","total_wt_arr_last_slp":"2.4364","total_num_ords":"1630","total_wt_ivwap_slp":"6.0969","total_wt_arr_slp":"1.7889","total_ord_qty":"576991"}

我怎么得到的?

更新:现在已经这样做了:

UPDATE: Doing this right now already:

var json_temp = JSON.stringify(json4);
    console.log("json_temp")
    console.log(json_temp);
    var json_temp1 = json_temp[0];
    console.log("json temp1");
    console.log(json_temp1);

但是在console.log中得到以下内容: 解决此问题

But getting the following in console.log: Getting this problem

推荐答案

仅引用这样的对象:

var array = [{"total_exec_qty":"286595","total_notional":"21820771.72","total_wt_arr_last_slp":"2.4364","total_num_ords":"1630","total_wt_ivwap_slp":"6.0969","total_wt_arr_slp":"1.7889","total_ord_qty":"576991"}];

var object = array[0];

或者，您可以复制对象并将其重新分配给相同的变量，如下所示，请注意:第二种方法要贵一些.

Alternatively you could copy the object and reassign it to the same variable like the following, note: This second method is a bit more expensive.

var data = [{"total_exec_qty":"286595","total_notional":"21820771.72","total_wt_arr_last_slp":"2.4364","total_num_ords":"1630","total_wt_ivwap_slp":"6.0969","total_wt_arr_slp":"1.7889","total_ord_qty":"576991"}];

data = JSON.parse(JSON.stringify(data[0]));

此处是一个可行的示例.
