angularjs - Angular Js，检查 Angular js中逗号分隔字符串中的子字符串

Question

我从 localstorage 得到了以下结果，

HD, TA, DI

现在在 angular js 中，我想根据这些数据显示 div:

HD      : Only display Home Delivery Button.
HD, TA  : Display Home Delivery and Take Away Buttons.
HD,TA,DI: Display Home Delivery, Take Away, dine In Buttons.

<div ng-if="result==What should be here"></div>

Answer 1

可以直接在ng-if中使用($scope.items='HD, TA, DI')

  <button ng-if="items.indexOf('HD')>=0">HD</button>
  <button ng-if="items.indexOf('TA')>=0">TA</button>
  <button ng-if="items.indexOf('DI')>=0">DI</button>
