這篇文章主要介紹了vue19 組建 Vue.extend component、組件模版、動(dòng)態(tài)組件的實(shí)例代碼,非常不錯(cuò)，具有一定的參考借鑒價(jià)值，需要的朋友可以參考下

具體代碼如下所示：

下面看下vue component動(dòng)態(tài)組件

動(dòng)態(tài)組件

通過component標(biāo)簽的is屬性來(lái)進(jìn)行組件的切換

is的屬性值決定要顯示的組件，所以將is的屬性值設(shè)置為data中的值，以便于動(dòng)態(tài)變化

<template>
  <div class="app">
      <component :is="組件名稱">
 
      </component>
  </div>
</template>
