用另一个数组过滤一个数组 - JavaScript
javascriptweb developmentfront end technologyobject oriented programming更新于 2026/1/1 0:44:17
假设，我们有一个数组和类似以下的对象 −
const main = [
{name: "Karan", age: 34},
{name: "Aayush", age: 24},
{name: "Ameesh", age: 23},
{name: "Joy", age: 33},
{name: "Siddarth", age: 43},
{name: "Nakul", age: 31},
{name: "Anmol", age: 21},
];
const names = ["Karan", "Joy", "Siddarth", "Ameesh"];
我们需要编写一个 JavaScript 函数，该函数接受两个这样的数组，并就地过滤第一个数组，使其仅包含第二个数组中包含其 name 属性的对象。
示例
以下是代码 −
const main = [
{name: "Karan", age: 34},
{name: "Aayush", age: 24},
{name: "Ameesh", age: 23},
{name: "Joy", age: 33},
{name: "Siddarth", age: 43},
{name: "Nakul", age: 31},
{name: "Anmol", age: 21},
];
const names = ["Karan", "Joy", "Siddarth", "Ameesh"];
const filterUnwanted = (main, names) => {
for(let i = 0; i < main.length; ){
if(names.includes(main[i].name)){
i++;
continue;
};
main.splice(i, 1);
};
};
filterUnwanted(main, names);
console.log(main);
这将在控制台上产生以下输出 −
[
{ name: 'Karan', age: 34 },
{ name: 'Ameesh', age: 23 },
{ name: 'Joy', age: 33 },
{ name: 'Siddarth', age: 43 }
]
