问题:
This question already has an answer here: 这个问题已经在这里有了答案:
Let's say I have an array of four objects: 假设我有四个对象组成的数组:
var jsObjects = [
{a: 1, b: 2},
{a: 3, b: 4},
{a: 5, b: 6},
{a: 7, b: 8}
];
Is there a way that I can get the third object ( {a: 5, b: 6}
) by the value of the property b
for example without a for...in
loop? 有没有一种方法可以通过属性b
的值获取第三个对象( {a: 5, b: 6}
),例如,没有for...in
循环?
