//This function allows remove even array from array
var removeFromArr = function(arr, elem) { 
    var i, len = arr.length, new_arr = [],
    sort_fn = function (a, b) { return a - b; };
    for (i = 0; i < len; i += 1) {
        if (typeof elem === 'object' && typeof arr[i] === 'object') {
            if (arr[i].toString() === elem.toString()) {
                continue;
            } else {                    
                if (arr[i].sort(sort_fn).toString() === elem.sort(sort_fn).toString()) {
                    continue;
                }
            }
        }
        if (arr[i] !== elem) {
            new_arr.push(arr[i]);
        }
    }
    return new_arr;
}

使用实例

var arr = [1, '2', [1 , 1] , 'abc', 1, '1', 1];
removeFromArr(arr, 1);
//["2", [1, 1], "abc", "1"]

var arr = [[1, 2] , 2, 'a', [2, 1], [1, 1, 2]];
removeFromArr(arr, [1,2]);
//[2, "a", [1, 1, 2]]

你可以使用underscore.js。这真的让事情变得简单。

例如，用这个:

var result = _.without(['three','seven','eleven'], 'seven');

结果是[' 3 '，' 11 ']。

在你的情况下，你必须写的代码是:

ary = _.without(ary, 'seven')

它减少了你编写的代码。

鉴于没有一个漂亮的ES6函数，这里有一个简单且可重用的ES6函数。

const removeArrayItem = (arr, itemToRemove) => {
  return arr.filter(item => item !== itemToRemove)
}

用法:

const items = ['orange', 'purple', 'orange', 'brown', 'red', 'orange']
removeArrayItem(items, 'orange')

方法1

var ary = ['three', 'seven', 'eleven'];
var index = ary.indexOf('seven'); // get index if value found otherwise -1

if (index > -1) { //if found
  ary.splice(index, 1);
}

方法2

一条衬垫

var ary = ['three', 'seven', 'eleven'];
filteredArr = ary.filter(function(v) { return v !== 'seven' })


// Or using ECMA6:
filteredArr = ary.filter(v => v !== 'seven')

这样看看:

for(var i in array){
    if(array[i]=='seven'){
        array.splice(i,1);
        break;
    }
}

在函数中:

function removeItem(array, item){
    for(var i in array){
        if(array[i]==item){
            array.splice(i,1);
            break;
        }
    }
}

removeItem(array, 'seven');

这可以是一个全局函数或一个自定义对象的方法，如果你不允许添加到本机原型。它从数组中删除与任何参数匹配的所有项。

Array.prototype.remove = function() {
    var what, a = arguments, L = a.length, ax;
    while (L && this.length) {
        what = a[--L];
        while ((ax = this.indexOf(what)) !== -1) {
            this.splice(ax, 1);
        }
    }
    return this;
};

var ary = ['three', 'seven', 'eleven'];

ary.remove('seven');

/*  returned value: (Array)
three,eleven
*/

使之成为全球性的

function removeA(arr) {
    var what, a = arguments, L = a.length, ax;
    while (L > 1 && arr.length) {
        what = a[--L];
        while ((ax= arr.indexOf(what)) !== -1) {
            arr.splice(ax, 1);
        }
    }
    return arr;
}
var ary = ['three', 'seven', 'eleven'];
removeA(ary, 'seven');


/*  returned value: (Array)
three,eleven
*/

并照顾IE8及以下-

if(!Array.prototype.indexOf) {
    Array.prototype.indexOf = function(what, i) {
        i = i || 0;
        var L = this.length;
        while (i < L) {
            if(this[i] === what) return i;
            ++i;
        }
        return -1;
    };
}
