您可以使用ES6. 例如,在此情况下删除值“ 3” :

var array=['1','2','3','4','5','6']
var newArray = array.filter((value)=>value!='3');
console.log(newArray);

产出:

["1", "2", "4", "5", "6"]

我不知道你如何期待阵列.remove( int) 的行为。 我可以想到三种可能性, 你可能会想要。

要删除索引 i 中的数组元素:

array.splice(i, 1);

如果您想要从数组中删除带有数值数的每个元素 :

for (var i = array.length - 1; i >= 0; i--) {
 if (array[i] === number) {
  array.splice(i, 1);
 }
}

如果您只想在索引 I 中使元素不再存在, 但是您不想让其它元素的索引改变 :

delete array[i];

更现代的ECMAScript 2015(原称和谐或ES6)方法。

const items = [1, 2, 3, 4];
const index = 2;

然后:

items.filter((x, i) => i !== index);

弹出 :

[1, 2, 4]

您可以使用 Babel 和多填充服务,以确保浏览器之间有很好的支持。

只将前34岁从年龄上移走,不是所有34岁的人:

ages.splice(ages.indexOf(34), 1);

或者您可以在全球定义一种方法 :

function remove(array, item){
    let ind = array.indexOf(item);
    if(ind !== -1)
        array.splice(ind, 1);
}

将所有34岁的人除去:

ages = ages.filter(a => a !== 34);
