不是使用索引，类似于来自Rahul Tripathi的评论链接答案，我会使用修改后的版本拉取对象按名称而不是传递整个对象。

Rather than use index of, similar to the comment linked answer from Rahul Tripat I would use a modified version to pull the object by name rather than pass the entire object.

function pluckByName(inArr, name, exists)
{
    for (i = 0; i < inArr.length; i++ )
    {
        if (inArr[i].name == name)
        {
            return (exists === true) ? true : inArr[i];
        }
    }
}

用法

// Find whether object exists in the array
var a = pluckByName(objectArray, 'A', true);

// Pluck the object from the array
var b = pluckByName(objectArray, 'B');
