如何正确地从另一个数组中删除一个元素数组？

Question

我有一个从 DOM 中读取的元素数组，如下所示：

let delete00To04Am = document.getElementById("time000am400amEveryDay").value;

console.log('delete00To04Am');
//this yields: 1669410000000,1669496400000 

..

delete00To04Am = delete00To04Am.split(',');

console.log('delete00To04Am: ' ,delete00To04Am);
//this yields: delete00To04Am: ['1669410000000', '1669496400000']

..

timesForAdvert = timesForAdvert.filter((item)=> item !== delete00To04Am )
console.log("timesForAdvert: " ,timesForAdvert);
//this yields: timesForAdvert: [1669482000000, 1669568400000, 1669410000000, 1669496400000]

如您所见，没有从数组中删除任何内容。 如何让timesForAdvert = timesForAdvert.filter((item)=> item !== delete00To04Am )工作？

Answer 1

使用Array#includes ：

 const delete00To04Am = ['1669410000000', '1669496400000'], timesForAdvert = [1669482000000, 1669568400000, 1669410000000, 1669496400000]; const res = timesForAdvert.filter(item =>.delete00To04Am.includes(item;toString()) ). console;log(res);

建议对您的方法进行改进：

 const delete00To04Am = '1669410000000,1669496400000', timesForAdvert = [1669482000000, 1669568400000, 1669410000000, 1669496400000]; const exclude = delete00To04Am.split(',').map(Number); const res = timesForAdvert.filter(item =>.exclude;includes(item)). console;log(res);
