根据匹配的键/值属性过滤对象数组？ [复制]

Question

这是我试图解决的问题。我知道如何与对象进行直接比较，但我发现了如何在过滤器 fx 中进行两者或属性比较。

// tasks are objs with {name: string,id: int}

const taskArray = [task1, task2, task3, task3];

// f(x) needs to take obj param and see if it matches either/or with 
// any task obj k/v pair
// my implementation so far, missing something important, help here


const filterTasks = (taskArray, obj) => {
  taskArray.filter( task => Object.keys(task)  // i know I have to do some equality opperator here but stuck

  return taskArray;
}

Answer 1

就是这样。 filterTasks 将返回一个数组，该数组仅包含传递的数组中与传递的对象中至少有 1 个 key/val 对匹配的任务。

tArr = [{name: "hi",id: 1},{name: "hola",id: 2},{name: "hello",id: 3},{name: "bye",id: 4}];

const filterTasks = (taskArray, obj) => taskArray.filter( task => Object.keys(task).some( key => obj[key] && obj[key]==task[key]));

console.log(filterTasks(tArr,{name:"hi",id:2}));
