ion-nav-bar可欣赏视图

Question

我正在从事一个离子1项目。我试图在其中一个视图中有一个带有后背按钮的Nav-bar，但它没有出现。我在Chrome上检查了一下，发现后面按钮的类变成了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

您可以尝试此代码。默认情况下，标题为类，如果您没有明确指定一个代码，则返回按钮不会显示。您可以在班级中使用 bar-light 或 bar-royal 。

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