在全局函数中，我们不能直接传递自定义值，但有很多方法，如下所示

 var ary = ['three', 'seven', 'eleven'];
 var index = ary.indexOf(item);//item: the value which you want to remove

 //Method 1
 ary.splice(index,1);

 //Method 2
 delete ary[index]; //in this method the deleted element will be undefined

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;
    };
}

ES6路。

const commentsWithoutDeletedArray = commentsArray.filter(comment => comment.Id !== commentId);

另一个变化:

if (!Array.prototype.removeArr) {
    Array.prototype.removeArr = function(arr) {
        if(!Array.isArray(arr)) arr=[arr];//let's be nice to people who put a non-array value here.. that could be me!
        var that = this;
        if(arr.length){
            var i=0;
            while(i<that.length){
                if(arr.indexOf(that[i])>-1){
                    that.splice(i,1);
                }else i++;
            }
        }
        return that;
    }
}

它又是循环中的indexOf()，但前提是要删除的数组相对于要清理的数组较小;每次移除都会缩短while循环。

CoffeeScript + jQuery变体:

arrayRemoveItemByValue = (arr,value) ->
  r=$.inArray(value, arr)
  unless r==-1
    arr.splice(r,1)
  # return
  arr

console.log arrayRemoveItemByValue(['2','1','3'],'3')

它只移除一个，而不是全部。

//编辑感谢MarcoCI的建议

试试这个:

function wantDelete(item, arr){
  for (var i=0;i<arr.length;i++){
    if (arr[i]==item){
      arr.splice(i,1); //this delete from the "i" index in the array to the "1" length
      break;
    }
  }  
}
var goodGuys=wantDelete('bush', ['obama', 'bush', 'clinton']); //['obama', 'clinton']
