MpxUsecreateGlobalState
保持全局范围中的状态，以便在Mpx实例之间重用。
用法
例子
js
// store.js
import { ref } from '@mpxjs/core'
import { createGlobalState } from '@mpxjs/mpxuse-core'
export const useGlobalState = createGlobalState(
() => {
const count = ref(0)
return { count }
}
)
// store.js
import { ref } from '@mpxjs/core'
import { createGlobalState } from '@mpxjs/mpxuse-core'
export const useGlobalState = createGlobalState(
() => {
const count = ref(0)
return { count }
}
)
复杂例子
js
// store.js
import { computed, ref } from '@mpxjs/core'
import { createGlobalState } from '@mpxjs/mpxuse-core'
export const useGlobalState = createGlobalState(
() => {
// state
const count = ref(initialValue)
// getters
const doubleCount = computed(() => count.value * 2)
// actions
function increment() {
count.value++
}
return { count, doubleCount, increment }
}
)
// store.js
import { computed, ref } from '@mpxjs/core'
import { createGlobalState } from '@mpxjs/mpxuse-core'
export const useGlobalState = createGlobalState(
() => {
// state
const count = ref(initialValue)
// getters
const doubleCount = computed(() => count.value * 2)
// actions
function increment() {
count.value++
}
return { count, doubleCount, increment }
}
)
