向函数内的对象添加值

我需要创建几个滑块实例。每个滑块有两个参数:一个元素ID和一个包含不同选项的对象。除一个选项(以下示例中的速度)外,所有滑块的所有选项都相同。

var swiper1 = new Swiper ('#swiper1', {
    width: 200,
    distance: 10,
    slides: 5,
    preventClick: true
    // ... many others options
    speed: 300 
});

var swiper2 = new Swiper ('#swiper2', {
    width: 200,
    distance: 10,
    slides: 5,
    preventClick: true
    // ... many others options
    speed: 500 
});

// ... many others instances of Swiper

为了缩短代码长度并避免多次复制/粘贴,我可以这样做:

var options = {
    width: 200,
    distance: 10,
    slides: 5,
    preventClick: true
    // ... many others options
    speed: 500 
}

var swiper1 = new Swiper ('#swiper1', options)
var swiper2 = new Swiper ('#swiper2', options)
var swiper3 = new Swiper ('#swiper3', options)
// ...

但是正如我所提到的,每个实例之间只有一个参数不同,所以我需要这样做:

var options = {
    width: 200,
    distance: 10,
    slides: 5,
    preventClick: true
    // ... many others options
}

var swiper1 = new Swiper ('#swiper1', {options, speed: 500})
var swiper2 = new Swiper ('#swiper2', {options, speed: 700})
var swiper3 = new Swiper ('#swiper3', {options, speed: 300})
// ...

但我不知道正确的方法是什么
