總結(jié)

本篇文章就到這里了，希望能夠給你帶來幫助，也希望您能夠多多關(guān)注腳本之家的更多內(nèi)容！

數(shù)組發(fā)生變化時，動態(tài)加載相應(yīng)數(shù)據(jù)

場景：點擊不同組件名稱，界面顯示相應(yīng)組件

步驟一：導(dǎo)入所需組件

步驟二：點擊 tab 選項卡，將對應(yīng)組件名添加進(jìn)數(shù)組

步驟三：使用動態(tài)組件，:is 屬性綁定組件名

<div v-for="(item, index) in componentData" :key="index">
  <components :is="item.componentName"/>
</div>
