javascript - 根据与另一个数组的重合对对象数组进行排序 JS REACT REDUX

Question

我有 2 个数组。 首先看起来像:

const arrOjObjects = [
{text: "HUF", value: 300.3803314317},
{text: "GBP", value: 0.7925201485},
{text: "IDR", value: 14127.9996377796},
{text: "ILS", value: 3.5020374898},
{text: "DKK", value: 6.7633795164}]

第二个看起来像:

const arr = ["ILS, "DKK"]

我需要按某种规则对arrOjObjects进行排序，如果对象文本的元素与数组arr的元素匹配，则该对象必须位于第一个，所有其他对象位于其后面

我需要一些排序规则，它将我的 arr 排序为这种状态:

const arrOjObjects = [
{text: "ILS", value: 3.5020374898}, // ILS is in arr
{text: "DKK", value: 6.7633795164} //  DKK is in arr
{text: "HUF", value: 300.3803314317},
{text: "GBP", value: 0.7925201485},
{text: "IDR", value: 14127.9996377796},
]

感谢您的解答!

Answer 1

您可以使用Array.prototype.sort

const arrOjObjects = [
	{text: "HUF", value: 300.3803314317},
	{text: "GBP", value: 0.7925201485},
	{text: "IDR", value: 14127.9996377796},
	{text: "ILS", value: 3.5020374898},
	{text: "DKK", value: 6.7633795164}]

	const arr = ["ILS", "DKK"];

	arrOjObjects.sort((a, b) => arr.includes(b.text) - arr.includes(a.text));

	console.log(arrOjObjects);
