请不要使用带有delete的变体-它会在数组中留下一个洞，因为它不会在删除的项之后重新索引元素。

> Array.prototype.remove=function(v){
...     delete this[this.indexOf(v)]
... };
[Function]
> var myarray=["3","24","55","2"];
undefined
> myarray.remove("55");
undefined
> myarray
[ '3', '24', , '2' ]

//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]]

如果你有唯一的值，顺序不重要，使用Set，它有delete():

var mySet = new Set(['three', 'seven', 'eleven']);
mySet.delete('seven'); // Returns true, successfully removed    
[...mySet];            // Returns ['three', 'eleven']

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;
    };
}

你要的是滤镜

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/filter

这将允许你做以下事情:

var ary = ['three', 'seven', 'eleven'];
var aryWithoutSeven = ary.filter(function(value) { return value != 'seven' });
console.log(aryWithoutSeven); // returns ['three', 'eleven']

这一点在其他地方也有注意到:https://stackoverflow.com/a/20827100/293492

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');
