var index,
    input = [1,2,3],
    indexToRemove = 1;
    integers = [];

for (index in input) {
    if (input.hasOwnProperty(index)) {
        if (index !== indexToRemove) {
            integers.push(result); 
        }
    }
}
input = integers;

此解决方案将需要一系列输入, 并将通过输入查找要删除的值。 这将在整个输入数组中循环, 结果将是第二个已经删除了特定索引的数组整数组。 然后将整数组复制到输入数组中 。

我还有一个从阵列中移除的好办法:

var words = ['spray', 'limit', 'elite', 'exuberant', 'destruction', 'present'];

const result = words.filter(word => word.length > 6);

console.log(result);
// expected output: Array ["exuberant", "destruction", "present"]

从数组中删除一个特定元素/字符串可在单班条中进行:

theArray.splice(theArray.indexOf("stringToRemoveFromArray"), 1);

此处:

阵列:要从

将字符串从矩阵中移除:要删除的字符串,而1是要删除的元素数量。

注 注 注 注 注注:如果“字符串要从阵列中移除”不位于数组中,这将删除数组的最后一个元素。

在移除该元素之前先检查该元素是否存在于您的阵列中, 总是很好的做法 。

if (theArray.indexOf("stringToRemoveFromArray") >= 0){
   theArray.splice(theArray.indexOf("stringToRemoveFromArray"), 1);
}

取决于客户电脑上是否有新版或旧版的剪贴条:

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

或

var array = ['1','2','3','4','5','6'];
var newArray = array.filter(function(item){ return item !== '3' });

“ 3” 是您想要从数组中删除的值。 然后, 数组将变成 :['1','2','4','5','6']

您可以使用Set,然后使用delete函数 :

const s = Set;
s.add('hello');
s.add('goodbye');
s.delete('hello');

Array.prototype.remove = function(x) {
    var y=this.slice(x+1);
    var z=[];
    for(i=0;i<=x-1;i++) {
        z[z.length] = this[i];
    }

    for(i=0;i<y.length;i++){
        z[z.length]=y[i];
    }

    return z;
}
