問:如何 Vue3 ㇐次就上手 答:只要把 2 改成 3,就好了
程式進入點
v-model component props 更名 vue2 v-model props : ['value'] v-model
更新是 $emit('input') vue3 v-model props : ['modelValue'] v-model 更新是 $emit('update:modelValue')
更新用 更新用 同 vue3 移除 .sync, 統㇐使用 v-model:[name]
lifecycle 更名
不會觸發更新 可以直接寫 Reactivity in depth
無 Teleport
無 Fragments
Vue3 composition-api 超香
composition - reactive
適合用到 這樣寫就有點麻煩 composition - ref 適合用到 也不錯寫喔 Kuro 大說:使用 ref,
template 裡都不需要寫 value
composition - ScriptSetup 二種寫法,大大滿足
composition - ScriptSetup setup props, import component
新的 不需要像 加 會自動判斷,讚 這裡只 所以 更新時並不會發生 略 watch and
watchEffect
composition - livecycle
composition custom hooks
不能這樣寫 composition custom hooks
composition custom hooks
css variables
Vue3 有二個功能目前做不到
IE 不能動
Vue3 Render 只能在指定的 DOM 裡 Vue2 可以直接取代指定的 DOM https://www.gogoro.com/tw/
當然也是可以把 Vue3 寫爛掉
這裡叫不到 裡的 這裡可以呼叫 裡的 看呀,這裡也不用加 data + setup 混搭
學習不需要為公司、⾧官或同事, 不需要為別人,只為你自己。 五倍紅寶石 高見龍
