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())    ));
