javascript - 根据字符串数组过滤对象数组 "with partial match"

Question

我有一个对象数组，我想根据另一个字符串数组的值过滤它，并删除不包含任何字符串的对象。

我尝试对字符串数组使用 split 并在 forEach 中搜索每个术语，但它没有用，然后尝试了以下用作过滤器的方法，但它过滤的是完全匹配而不是部分匹配。

var employees = [
  {"name": "zxc asd", "age":"30"},
  {"name": "asd", "age":"24"},
  {"name": "qwe", "age":"44"},
  {"name": "zxc", "age":"28"},
];

var keepNames = ["asd", "qwe"];

keepNames = keepNames.map(name => {
  return name.toLowerCase();
});


var filteredEmployees = employees.filter(emp => {
  return keepNames.indexOf(emp.name.toLowerCase()) !== -1;
});

console.log( filteredEmployees );

Expected Output[  
  {"name": "zxc asd", "age":"30"},
  {"name": "asd", "age":"24"},
  {"name": "qwe", "age":"44"}];

Actual Output [
  {"name": "asd", "age":"24"},
  {"name": "qwe", "age":"44"}]

如果有任何帮助，我将不胜感激。提前致谢

您还需要使用名称 keep 迭代数组并检查值。

var employees = [{ name: "zxc asd", age: "30" }, { name: "asd", age: "24" }, { name: "qwe", age: "44" }, { name: "zxc", age: "28" }],
    keep = ["asd", "qwe"],
    filtered = employees.filter(({ name }) =>
        keep.some(n => name.toLowerCase().includes(n))
    );

console.log(filtered);
