js循环匹配组合成新对象或js循环组合新数据

var Arry=[

{name: "vehicleTravelLicenseCopyBack", id: "a1"},

{name: "vehicleTravelLicenseCopyFront", id: "a2"},

{name: "idCardBack", id: "a3"},

{name: "idCardFront", id: "a4"}

]

为了把上面的东西便成下面的

var ImgObj={

idCardBack: "a1",

idCardFront: "a2",

vehicleTravelLicenseCopyBack: "a3",

vehicleTravelLicenseCopyFront: "a4"

}

1. 以前的做法定义一个全量对象

 Img: {

vehicleTravelLicenseCopyBack: void 0,

vehicleTravelLicenseCopyFront: void 0,

idCardBack: void 0,

idCardFront: void 0,

}

for (let v of Arry) {

for (let n in this.Img) {

if (v.name === n) {

ImgObj[n] = v.id

}

}

}

 2、我这是有多惨，今天才发现最快是这样的

for (let v of Arry) {

imgObj[v.name] = v.id

}

为什么当时用了两个数组，脑子进水了。。。
