如何将JSON数组转换为JavaScript 2D数组 [英] how to convert JSON array into JavaScript 2D array

问题描述

我想将以下JSON转换为JS 2D数组，但是我不确定如何在html中执行此操作。

I want to convert the following JSON into a JS 2D array, but I am not sure how to do this in html.

[{"fields": {"diameter": 23.0, "neighbourhood": "WEST END"}, "model": "hug.tree", "pk": 345}, 
 {"fields": {"diameter": 14.0, "neighbourhood": "MOUNT PLEASANT"}, "model": "hug.tree", "pk": 484}]

结果应类似于：

[[23.0, 'WEST END'], [14.0, 'MOUNT PLEASANT']]

非常感谢！ p>

Thank you so much!

推荐答案

这将适用于字段的所有字段，不仅适用于直径 或邻居。

This will work with all fields of "fields", not only for diameter or neighborhood.

演示：

var items = [{"fields": {"diameter": 23.0, "neighbourhood": "WEST END"}, "model": "hug.tree", "pk": 345}, {"fields": {"diameter": 14.0, "neighbourhood": "MOUNT PLEASANT"}, "model": "hug.tree", "pk": 484}];

var i = 0, result = [];

while(i < items.length){
    result.push([])
    for(var key in items[i].fields){
        result[result.length-1].push(items[i].fields[key])	
    }
    i++
}

document.write(JSON.stringify(result, null, 4));
