在jquery中为对象数组中的对象赋值

Question

我有一个对象数组

对象将采用以下格式

var newUserDetail={"Age":"21","name":"Vicky","UserId":"198303"};

现在我正在尝试比较UserId并替换值

//usersList contains array of newUserDetail kind of objects

jQuery(usersList).each(function(){
if(this.UserId==newUserDetail.UserId){
this=newUserDetail;
}
});

但它会抛出错误

Invalid left-hand side in assignment

Answer 1

设置数组条目：

jQuery(usersList).each(function (i) {
    if (this.UserId == newUserDetail.UserId) {
        usersList[i] = newUserDetail;
        return false; //if you want to break the loop
    }
});
