内咖啡冲咖啡:

my_array.splice(idx, 1) for ele, idx in my_array when ele is this_value

非就地解决办法

arr.slice(0,i).concat(arr.slice(i+1));

let arr = [10, 20, 30, 40, 50]

let i = 2 ; // position to remove (starting from 0)
let r = arr.slice(0,i).concat(arr.slice(i+1));

console.log(r);

您可以在 JavaScript 以多种方式完成此任务

1. 如果您知道该值的索引:在此情况下,您可以使用复数

   var arr = [1,2,3,4]
   // Let's say we have the index, coming from some API
   let index = 2;
   // splice is a destructive method and modifies the original array
   arr.splice(2, 1)
   

2. 如果您没有索引, 并且只有数值: 在此情况下, 您可以使用过滤器

   // Let's remove '2', for example
   arr = arr.filter((value)=>{
       return value !== 2;
   })
   

const arr = [1, 2, 3, 4, 5]
console.log(arr) // [ 1, 2, 3, 4, 5 ]

假设你想从Arr删除3号

const newArr = arr.filter(w => w !==3)
console.log(newArr) // [ 1, 2, 4, 5 ]

从字符串阵列中查找和删除一个特定的字符串:

var colors = ["red","blue","car","green"];
var carIndex = colors.indexOf("car"); // Get "car" index
// Remove car from the colors array
colors.splice(carIndex, 1); // colors = ["red", "blue", "green"]

 const Delete = (id) => {
      console.log(id)
     var index = Array.map(function(e){
      return e.id;
     
     }).indexOf(id);
     Array.splice(index,1);
     
}
