js 将一个二维数组 转为 一个对象

[Nirvanaxumm]

如将：
var dataset = [["长沙市",100,300,400],["株洲市",150,350,500],["湘潭市",80,275,355],["衡阳市",100,379,479],["郴州市",44,44,88],["常德市",58,80,138],["益阳市",730,800,830],["娄底市",135,500,635],["邵阳市",1,23,43],["湘西土家族苗族自治州",23,50,90],["张家界市",100,103,103],["怀化市",100,300,355],["永州市",100,300,400],["岳阳市",88,90,120]];
将数组第一项转对象键值，最后转为：
var dataset = {"长沙市":{100,300,400},"株洲市":{150,350,500},"湘潭市":{80,275,355},"衡阳市":{100,379,479},"郴州市":{44,44,88},"常德市",{58,80,138},"益阳市":{730,800,830},"娄底市":{135,500,635},"邵阳市":{1,23,43},"湘西土家族苗族自治州":{23,50,90},"张家界市":{100,103,103},"怀化市":{100,300,355},"永州市":{100,300,400},"岳阳市":{88,90,120}};

有点怪：）

[讨厌走开啦]

let translate = (data) => {
    let re = {};
    data.forEach(function (item) {
        re[item[0]] = item.slice(1);
    });
    return re;
}

大概是这么个思路，没测过，要用的话测试一下。

补充一下，返回的对象是{"长沙市":[100,300,400]}这样的，没有{100,300,400}这样的对象。

错了，是转成： var dataset = {"长沙市":{1:100,2:300,3:400},"株洲市":{1:150,2:350,3:500},"湘潭市":{1:80,2:275,3:355},"衡阳市":{1:100,2:379,3:479},"郴州市":{1:44,2:44,3:88},"常德市":{1:58,2:80,3:138},"益阳市":{1:730,2:800,3:830},"娄底市":{1:135,2:500,3:635},"邵阳市":{1:1,2:23,3:43},"湘西土家族苗族自治州":{1:23,2:50,3:90},"张家界市":{1:100,2:103,3:103},"怀化市":{1:100,2:300,3:355},"永州市":{1:100,2:300,3:400},"岳阳市":{1:88,2:90,3:120}};

var dataset = [["长沙市",100,300,400],["株洲市",150,350,500],["湘潭市",80,275,355],["衡阳市",100,379,479],["郴州市",44,44,88],["常德市",58,80,138],["益阳市",730,800,830],["娄底市",135,500,635],["邵阳市",1,23,43],["湘西土家族苗族自治州",23,50,90],["张家界市",100,103,103],["怀化市",100,300,355],["永州市",100,300,400],["岳阳市",88,90,120]];
var obj = {};

	var t = {};
	for (var i = 1; i < v.length; i++)
		t[i] = v[i];
	obj[v[0]] = t;

alert(JSON.stringify(obj));

引用 1 楼 讨厌走开啦 的回复:

let translate = (data) => {
    let re = {};
    data.forEach(function (item) {
        re[item[0]] = item.slice(1);
    });
    return re;
}

可以不用ES6帮我实现下吗？我不是程序员，套下这个格式有用。呵呵。

还有一种方法，用正则表达式把花中括号换成大括号，在进行一个格式转换，存成文本，在用evel函数调用
