对象Javascript循环的动态属性名称 [英] Dynamic property names for loop of object Javascript

问题描述

在Javascript中是否有一种巧妙的方法来遍历数组中对象的属性名称？

In Javascript is there a clever way to loop through the names of properties in objects in an array?

我有多个属性的对象，包括guest1到guest100。除了下面的循环之外，我还想要另一个循环遍历guestx属性而不必长时间写出来的循环。如果我必须将下面的代码编写成结果[i] .guest100，这将是一个非常长的列表，这将是一些丑陋的代码。

I have objects with several properties including guest1 to guest100. In addition to the loop below I'd like another one that would loop through the guestx properties without having to write it out long hand. It's going to be a very long list if I have to write the code below to results[i].guest100, that is going to be some ugly looking code.

for (var i = 0; i < results.length; i++) {
if (results[i].guest1 != "") {
    Do something;
}
if (results[i].guest2 != "") {
    Do something;
}
if (results[i].guest3 != "") {
    Do something;
}
etcetera...
}

推荐答案

试试这个：

for (var i = 0; i < results.length; i++) {
    for (var j=0; j <= 100; j++){
        if (results[i]["guest" + j] != "") {
            Do something;
        }
    }
}
