我有一个对象数组,其中包含很多重复/无用的数据。我需要根据客户ID进行过滤,并选择具有最新日期的对象。数据看起来像这样:
let data = [
{
CUSTOMER_PERMANENT_ID: "2495",
EMAIL: "abs@gmail.com",
EVENT_ACTIVATION_TIME: "2019-10-25 13:57:38.79",
},
{
CUSTOMER_PERMANENT_ID: "2495",
EMAIL: "abs@gmail.com",
EVENT_ACTIVATION_TIME: "2019-10-28 20:04:49.016",
},
{
CUSTOMER_PERMANENT_ID: "2495",
EMAIL: "abs@gmail.com",
EVENT_ACTIVATION_TIME: "2019-10-28 20:04:49.019",
},
{
CUSTOMER_PERMANENT_ID: "5995",
EMAIL: "John@gmail.com",
EVENT_ACTIVATION_TIME: "2019-10-28 17:24:10.98",
}
]
我尝试了以下功能,但是仅当有两个重复的对象时才起作用,如果有两个以上的对象,它将返回所有对象。
public fixDcppSelectedClientData() {
let result = [];
for (let item of this.arr) {
for (let checkingItem of this.arr) {
if (
this.arr.indexOf(item) !=
this.arr.indexOf(checkingItem) &&
item.CUSTOMER_PERMANENT_ID == checkingItem.CUSTOMER_PERMANENT_ID &&
new Date(item.EVENT_ACTIVATION_TIME).getTime() <
new Date(checkingItem.EVENT_ACTIVATION_TIME).getTime()
) {
if (result.indexOf(checkingItem) == -1) {
result.push(checkingItem);
}
}
}
}
console.log("filtered data is ", result);
}
我需要对这个话题进行更多的研究,但是如果有人可以同时提供帮助,那就太好了。

display: inline-block; // show element when you have the class name 'show'

此代码过滤器重复ID
$keyboard = new Keyboard(...$titles);
