[英]How to toggle between components in vue.js?
我開發了一個名為 Dashboard.vue 的頁面,該頁面包含三個子組件(Display、sortBooksLowtoHigh、sortBooksHightoLow)。 儀表板組件還包含一個選擇選項,其中有兩個選項“價格:從高到低和價格:從低到高”,
如果我點擊 price:LowToHigh 選項,那么它會隱藏 Display 組件並顯示 sortBooksLowtoHigh 組件,它工作正常,
現在,當我單擊“價格:從高到低”選項時,我又導入了一個名為 sortBooksHightoLow 的組件,它應該隱藏 DisplayComponent 並顯示 sortBooksHightoLow 組件。如何實現這件事請幫幫我

emmmm... HightoLow => HighToLow。
在我看來,可以有幾種方法來實現我認為您的問題所要求的組件的條件渲染。 其中兩個非常有用的是:
v-if
和v-else
必須定義一個標志來處理組件渲染的邏輯。 此外,將它們包裝在過渡標簽中是一個好主意,可以通過過渡進行切換。<transition>
<component1 v-if="flag" />
<component2 v-else />
</transition>
component
標簽和is
。 然后可以使用組件的名稱切換組件。<component is="nameofComponent" />
您可以在 vuejs 文檔中閱讀更多關於動態組件的信息。
雖然動態組件看起來很整潔,但帶有過渡的開關可能是一個不錯的補充。
