MpxUseuseProjection
从一个范围到另一个范围的响应式数字映射。
用法
ts
import { useProjection } from '@mpxjs/mpxuse-math'
const input = ref(0)
const projected = useProjection(input, [0, 10], [0, 100])
input.value = 5 // projected.value === 50
input.value = 10 // projected.value === 100
import { useProjection } from '@mpxjs/mpxuse-math'
const input = ref(0)
const projected = useProjection(input, [0, 10], [0, 100])
input.value = 5 // projected.value === 50
input.value = 10 // projected.value === 100
