序列的数组索引

Question

我有一组这样的对象

0: {slot_id: 'slot_8848241006_1657877963_1657886201'}
2: {slot_id: 'slot_8848241006_1657877963_1657886978'}
4: {slot_id: 'slot_9495414200_1657194770_1657877482'}
6: {slot_id: 'slot_9495414200_1657194770_1657886410'}
8: {slot_id: 'slot_9495414200_1657194770_1657886563'}

我想要这样

0: {slot_id: 'slot_8848241006_1657877963_1657886201'}
1: {slot_id: 'slot_8848241006_1657877963_1657886978'}
2: {slot_id: 'slot_9495414200_1657194770_1657877482'}
3: {slot_id: 'slot_9495414200_1657194770_1657886410'}
4: {slot_id: 'slot_9495414200_1657194770_1657886563'}

在如何更改数组的索引值方面需要帮助？

Answer 1

//empty array
var array = [0, 1, 2, 3, , 3,,,,,, 4,, 4,, 5,, 6,,,,];

var filtered = array.filter(function (el) {
return el != null;
});
console.log(filtered);
