如何在循环中添加“或”运算？

Question

我想循环下面的代码。如何将列名保留在数组中并通过循环返回？ return Students.filter((singleItem) => {   singleItem["id"].toLowerCase().includes(value.toLowerCase()) ||   singleItem["name"].toLowerCase().includes(value.toLowerCase()) ||   singleItem["class"].toLowerCase().includes(value.toLowerCase())  });例如：  var columns= ["id","name","class"];  return Students.filter((singleItem) => {   columns.map(data=>{   singleItem[data].toLowerCase().includes(value.toLowerCase()); //I have to use the "||" operation here. How can I use it in the loop?     }) });

Answer 1

您可以迭代给定的键并使用 提前退出Array#some。

var columns = ["id", "name", "class"];

return Students.filter(singleItem =>

    ["id", "name", "class"].some(key =>

        singleItem[key].toLowerCase().includes(value.toLowerCase())

    )

);
