Question

obj = [
    { "name": "john", "age": "25" },  
    { "name": "jose", "age": "30" }, 
    { "name": "mark", "age": "32" }
]

var country = [USA, UK, China]

这是我目前的对象。我必须将另一个数组中的国家/地区添加到每个项目Ep>中

obj = [
    { "name": "john", "age": "25", "country": "USA" }, 
    { "name": "jose", "age": "30", "country": "UK" }, 
    { "name": "mark", "age": "32", "country": "China" }
]

Answer 1

试试这个，

obj = [
    { "name": "john", "age": "25" },  
    { "name": "jose", "age": "30" }, 
    { "name": "mark", "age": "32" }
]

var country = ['usa','china'];


for (var i = 0; i < country.length; i++) {
   obj[i].country=country[i];

}

console.log(obj);

Answer 2

if(obj.length==country.length){
    for(i=0; i<obj.length; i++){
        obj[i].country=country[i];
    }
}

此外，您还需要在国家/地区名称旁边添加引号。

Answer 3

尝试：

$(country).each(function (i,e) {
    obj[i].country = e;
});

它遍历数组，i是索引，e是元素。如果您需要向对象添加属性，您可以只分配它，因此obj[i]将为您提供对象，以指定仅为其分配的country属性。

我必须在javascript中将新项添加到对象中
