let removeAnElement = (arr, element)=>{
    let findIndex = -1;
    for (let i = 0; i<(arr.length); i++){
        if(arr[i] === element){
            findIndex = i;
            break;
        }
    }
    if(findIndex == -1){
        return arr;
    }
    for (let i = findIndex; i<(arr.length-1); i++){
        arr[i] =  arr[i+1];
    }
    arr.length -= 1;
    return arr;
}

let array = ['apple', 'ball', 'cat', 'dog', 'egg'];
let removeElement = 'ball';

let tempArr2 = removeAnElement(array, 'dummy');
console.log(tempArr2);
// ['apple', 'cat', 'dog', 'egg']

let tempArr = removeAnElement(array, removeElement);
console.log(tempArr);`enter code here`
// ['apple', 'cat', 'dog', 'egg']

检查一下这个代码 每个代码都有效主浏览器.

remove_item = function(arr, value) {
 var b = '';
 for (b in arr) {
  if (arr[b] === value) {
   arr.splice(b, 1);
   break;
  }
 }
 return arr;
};

var array = [1,3,5,6,5,9,5,3,55]
var res = remove_item(array,5);
console.log(res)

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

我对JavaScript很新,需要这个功能。我只是写了这个:

function removeFromArray(array, item, index) {
  while((index = array.indexOf(item)) > -1) {
    array.splice(index, 1);
  }
}

然后,当我想使用它:

//Set-up some dummy data
var dummyObj = {name:"meow"};
var dummyArray = [dummyObj, "item1", "item1", "item2"];

//Remove the dummy data
removeFromArray(dummyArray, dummyObj);
removeFromArray(dummyArray, "item2");

输出 - 如预期的那样。 [“项目1”、“项目1”]

你可能跟我有不同的需要,所以你可以轻易地修改,以适合他们。我希望这能帮助别人。

let array = [5,5,4,4,2,3,4]    
let newArray = array.join(',').replace('5','').split(',')

如果您想要删除一个当前项目, 此示例将有效 。

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