您只需要按元素或索引过滤 :

var num = [5, 6, 5, 4, 5, 1, 5]; var result1 = num.filter((el, index) => el != 5) // for remove all 5 var result2 = num.filter((el, index) => index != 5) // for remove item with index == 5 console.log(result1); console.log(result2);

使用$.inAray, 以其价值删除一个元素:

$(document).ready(function(){
    var arr = ["C#","Ruby","PHP","C","C++"];
    var itemtoRemove = "PHP";
    arr.splice($.inArray(itemtoRemove, arr),1);
});

我设定了一个函数:

function pop(valuetoremove, myarray) {
    var indexofmyvalue = myarray.indexOf(valuetoremove);
    myarray.splice(indexofmyvalue, 1);
}

并用它这样:

pop(valuetoremove, myarray);

我还有一个从阵列中移除的好办法:

var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]

除了所有这些解决方案之外, 它也可以用阵列来完成. 减量...

const removeItem = 
    idx => 
    arr => 
    arr.reduce((acc, a, i) =>  idx === i ? acc : acc.concat(a), [])

const array = [1, 2, 3]
const index = 1

const newArray = removeItem(index)(array) 

console.log(newArray) // logs the following array to the console : [1, 3]

...或者一个循环函数(诚实地说不是那么优雅...也许有人有更好的循环解决方案? ? )...

const removeItemPrep = 
    acc => 
    i => 
    idx => 
    arr => 

    // If the index equals i, just feed in the unchanged accumulator(acc) else...
    i === idx ? removeItemPrep(acc)(i + 1)(idx)(arr) :

    // If the array length + 1 of the accumulator is smaller than the array length of the original array concatenate the array element at index i else... 
    acc.length + 1 < arr.length ? removeItemPrep(acc.concat(arr[i]))(i + 1)(idx)(arr) : 

    // return the accumulator
    acc 

const removeItem = removeItemPrep([])(0)

const array = [1, 2, 3]
const index = 1

const newArray = removeItem(index)(array) 

console.log(newArray) // logs the following array to the console : [1, 3]

使用数组过滤法 :

let array = [1, 2, 3, 4, 511, 34, 511, 78, 88];

let value = 511;
array = array.filter(element => element !== value);
console.log(array)
