网上有不少文章给出了Composition代替Minix的方式和优点,但是本人没有找到如何方法中使用props。下面的例子给出了link作为composition如何在cell中使用
link minix
import { computed, toRefs } from 'vue'
export default function (instance: any, props: any): any {
const { to, replace, target, append } = toRefs(props)
const router = instance?.appContext.config.globalProperties.$router
const linkUrl = computed(() => {
const type = typeof to?.value
if (type !== 'string') {
return null
}
if ((to?.value as string).includes('//')) {
/* Absolute URL, we do not need to route this */
return to?.value
}
if (router) {
const current = router.currentRoute
const route = router.resolve(to?.value, current, append.value)
return route ? route.href : to?.value
}
return to?.value
})
const handleClick = (newWindow = false) => {
if (newWindow) {
let toOpen = to?.value
if (router) {
const current = router.currentRoute
const route = router.resolve(to?.value, current, append.value)
toOpen = route ? route.href : to?.value
}
window.open(toOpen as string)
} else {
if (router) {
if ((typeof to?.value === 'string') && to.value.includes('//')) {
window.location.href = to.value
} else {
replace.value ? router.replace(to?.value) : router.push(to?.value)
}
} else {
window.location.href = to?.value as string
}
}
}
const handleCheckClick = (event: any, newWindow = false) => {
if (to?.value) {
if (target.value === '_blank') {
return false
} else {
event.preventDefault()
handleClick(newWindow)
}
}
}
return {
linkUrl,
handleClick,
handleCheckClick
}
}
