Question

我想将以下JSON转换为JS 2D数组，但我不知道如何在html中执行此操作。

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

结果应该是这样的：

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

非常感谢你！

Answer 1

这适用于“字段”的所有字段，不仅适用于diameter或neighborhood。

<强>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));

Answer 2

对于json中的每个项目，将diameter和neighborhood的新数组推送到结果数组中。

var json = [{"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 done = [];
json.forEach(function(object){
    done.push([object.fields.diameter,object.fields.neighbourhood]);
});

console.log(done);
