用法
¥Usage
ts
import { useSorted } from '@vueuse/core'
// general sort
const source = [10, 3, 5, 7, 2, 1, 8, 6, 9, 4]
const sorted = useSorted(source)
console.log(sorted.value) // [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
console.log(source) // [10, 3, 5, 7, 2, 1, 8, 6, 9, 4]
// object sort
const objArr = [{
name: 'John',
age: 40,
}, {
name: 'Jane',
age: 20,
}, {
name: 'Joe',
age: 30,
}, {
name: 'Jenny',
age: 22,
}]
const objSorted = useSorted(objArr, (a, b) => a.age - b.age)脏模式
¥dirty mode
脏模式会改变源数组。
¥dirty mode will change the source array.
ts
const source = ref([10, 3, 5, 7, 2, 1, 8, 6, 9, 4])
const sorted = useSorted(source, (a, b) => a - b, {
dirty: true,
})
console.log(source)// output: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10类型声明
