我有,
[
{
_id: 60673d40ba14f617081bdf4d,
ImageName: 'Flowers',
ImagePath: './public/assets/img/1.jpg',
Description: 'A cool Image',
__v: 0
},
{
_id: 60673e099d76ef16a8ec4588,
ImageName: 'Water Bubble Colors',
ImagePath: './public/assets/img/2.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: 60673e39f10c4a12a0f4ea31,
ImageName: 'Egg Silhouette Wallpaper',
ImagePath: './public/assets/img/3.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: 60673e4a15d9bb18a01312df,
ImageName: 'Pencil BW ',
ImagePath: './public/assets/img/4.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: 60673e6c6de9bb1bf8c65d25,
ImageName: 'Water',
ImagePath: './public/assets/img/5.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: 60673e8a8af58b1fb8b11596,
ImageName: 'Dining Plate',
ImagePath: './public/assets/img/6.jpg',
Description: 'Wallpapers',
__v: 0
}
]
和 var id = req.params.id
基本上是 60673e8a8af58b1fb8b11596
。
现在如何使用我拥有的 id
变量过滤数组并获得具有 id 的整个对象?我想要带有 _id、ImageName、ImagePath、__v 和 Description 的整个对象。
我搜索了很多,找到了 array.filter
方法,但是它太复杂了,没有帮助我,我更加困惑了。
最佳答案
您可以尝试使用 Array.prototype.filter()
检查 ID:
var data = [
{
_id: '60673d40ba14f617081bdf4d',
ImageName: 'Flowers',
ImagePath: './public/assets/img/1.jpg',
Description: 'A cool Image',
__v: 0
},
{
_id: '60673e099d76ef16a8ec4588',
ImageName: 'Water Bubble Colors',
ImagePath: './public/assets/img/2.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: '60673e39f10c4a12a0f4ea31',
ImageName: 'Egg Silhouette Wallpaper',
ImagePath: './public/assets/img/3.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: '60673e4a15d9bb18a01312df',
ImageName: 'Pencil BW ',
ImagePath: './public/assets/img/4.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: '60673e6c6de9bb1bf8c65d25',
ImageName: 'Water',
ImagePath: './public/assets/img/5.jpg',
Description: 'Wallpapers',
__v: 0
},
{
_id: '60673e8a8af58b1fb8b11596',
ImageName: 'Dining Plate',
ImagePath: './public/assets/img/6.jpg',
Description: 'Wallpapers',
__v: 0
}
]
var id = '60673e8a8af58b1fb8b11596'; //req.params.id
var res = data.filter(d => d._id == id);
console.log(res);
