遍历数组并获取具有特定字符串的对象

Question

ex:

{
  "data": [
    {
      "name": "grape",
      "color": "purple"
    },
    {
      "name": "apple",
      "color": "green"
    }
  ]
}

Let's say I ONLY want to get objects with the color of purple. How would I do this?

Answer 1

Something like this? You can use JavaScript's Array.filter() .

 const obj = { "data": [ { "name": "grape", "color": "purple" }, { "name": "apple", "color": "green" } ] }; const result = obj.data.filter(element => element.color === 'purple'); console.log(result); 

This filters through the array and returns a list of objects with the color of purple.
