Question

我正在研究Ionic 1项目。我正试图在其中一个视图中设置一个带有后退按钮的导航栏，但它没有出现。我在Chrome上进行了检查，发现后退按钮的类变为hide。无论如何我可以让它出现吗？

这是我的代码：

<ion-view ng-controller="GuDetailCtrl">
 <ion-nav-bar class="bar-positive">
<ion-nav-back-button class="button-icon ion-arrow-left-c show">
</ion-nav-back-button>
 </ion-nav-bar>
 <ion-content class="padding">
<div class="list">
  <label class="item item-input">
    <span class="input-label">Name</span>
    <span>{{hotel.name}}</span>
  </label>
  <label class="item item-input">
    <span class="input-label">Locality</span>
    <span>{{hotel.locality}}</span>
  </label>
  <label class="item item-input">
    <span class="input-label">Amenities</span>
    <span>{{hotel.amenities}}</span>
  </label>
</div>
<button class="button button-positive" ng-click="modal.show()">
  Create Booking
</button>

<script id="templates/booking.html" type="text/ng-template">
  <ion-modal-view>
    <ion-header-bar class="bar bar-header bar-positive">
      <h1 class="title">New Booking</h1>
      <button class="button button-clear button-primary" ng-click="modal.hide()">Cancel</button>
    </ion-header-bar>
    <ion-content class="padding">
      <div class="list">
        <label class="item item-input">
          <span class="input-label">Check-in Date</span>
          <input ng-model="newBooking.inDate" type="date">
        </label>
        <label class="item item-input">
          <span class="input-label">Check-out Date</span>
          <input ng-model="newBooking.outDate" type="date">
        </label>
        <label class="item item-input">
          <span class="input-label">No. of Rooms</span>
          <input ng-model="newBooking.rooms" type="number">
        </label>
        <button class="button button-full button-positive" ng-click="createBooking(newBooking)">Create</button>
      </div>
    </ion-content>
  </ion-modal-view>
</script>

 </ion-content>
</ion-view>

Answer 1

您可以尝试使用此代码。默认情况下，标题有一个类，如果您没有明确指定，则后退按钮不会显示。你可以在课堂上使用 bar-light 或 bar-royal 。

<ion-nav-bar class="bar-royal">
    <ion-nav-back-button>Back</ion-nav-back-button>
</ion-nav-bar>
