JSON數據上的Angular JS中的光滑輪播無法正常工作

Question

我使用這個程序github.com/vasyabigi/angular-slick 。 它不適用於動態數據。 它僅適用於靜態數據。 在動態數據中，它顯示的是水平方向的垂直圖像，沒有旋轉木馬。請幫助我。 這是我的事

Answer 1

有一個稱為init-onLoad的屬性，只需使其正確即可。

<slick init-onload=true data="awesomeThings">
  ...
</slick>

Answer 2

以防萬一，使用以下設置對您不起作用。

init-onload = true data =“ awesomeThings”

改用它。

ng-if =“ awesomeThings.length”
