var remove = function(array, value) {
    var index = null;

    while ((index = array.indexOf(value)) !== -1)
        array.splice(index, 1);

    return array;
};

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');

真的，我不明白为什么不能用

arr = arr.filter(value => value !== 'seven');

或者你可能想使用普通的JS

arr = arr.filter(function(value) { return value !== 'seven' });

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')

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')
