我不知道是否存在执行此操作的现有下划线方法，但您可以实现与普通javascript相同的结果。

I don't know if there is an existing underscore method that does this, but you can achieve the same result with plain javascript.

Array.prototype.getIndexBy = function (name, value) {
    for (var i = 0; i < this.length; i++) {
        if (this[i][name] == value) {
            return i;
        }
    }
    return -1;
}

然后你可以这样做：

var data = tv [tv.getIndexBy（id，2）]
