javascript - 用对象属性替换数组元素

Question

我的对象

var person = [{ FIrstName: "", LastName: "", MiddleName: "" }];

我的数据

var names = [
    "Steve", "Mark", "John",     // person 1
    "James", "Andrew", "wells",  // person 2
    "Clarke", "Finche", "Gomes"  // person 3
];

所以我想将 names 数组推送到 person 对象中。

$(names).each(function (index, item) {
    //Here I need to push the values
}); 

如您所见，我没有单独的姓氏和中间名数组。

我希望我的输出为:

[
    { "FIrstName": "Steve", "LastName": "Mark", "MiddleName": "John" },
    { "FIrstName": "James", "LastName": "Andrew", "MiddleName": "wells" },
    { "FIrstName": "Clarke", "LastName": "Finche", "MiddleName": "Gomes" }
]

请帮助我。

Answer 1

这是您想要实现的目标。

var names = ["Steve","Mark","John","James","Andrew", "wells","Clarke","Finche","Gomes"];
var person = [];

for(var i=0; i<names.length; i+=3) {
    person.push({
    	FIrstName: names[i],
    	LastName: names[i+1],
    	MiddleName: names[i+2]
    });
}

document.write(JSON.stringify(person));

您也可以首先将数组拆分为 block 数组..

var names = ["Steve","Mark","John","James","Andrew", "wells","Clarke","Finche","Gomes"];
var chunks = [];

while(names.length) {
	chunks.push(names.splice(0, 3));
}

var result = chunks.map(function(person) {
	return {
    	FIrstName: person[0],
    	LastName: person[1],
    	MiddleName: person[2]
    }
});

document.write(JSON.stringify(result));
