css - 图像未显示在设备上(Ionic2 应用程序)

Question

我正在 Ionic2 中开发一个应用程序。行的背景中有一张图片。我还在行中放置了一张图片。图像在浏览器上看起来很好( ionic 服务)。但是，只有背景图像显示在一个真正的移动设备。会是什么原因。

Answer 1

在您的 html 中，您的相对路径不正确。

html 中的每个 Assets 都从路径中检索:'./assets/' 所以你的文件看起来像:

<ion-grid> 
       <ion-row class="menurow">
           <ion-col class="img2">
              <img src="./assets/images/noun_683380_cc.png">
              <h4 class="text text-center">OUR SERVICIES</h4>
           </ion-col>
        </ion-row>
        <ion-row class="menurow">
          <ion-col class="img3">
              <img src="./assets/images/news.png">
              <h4 class="text text-center">REFERENCES</h4>
          </ion-col>
        </ion-row>
        <ion-row class="menurow">
          <ion-col class="img4">
               <img src="./assets/images/photo.png">
               <h4 class="text text-center">PHOTOS</h4>
          </ion-col>
        </ion-row>
        <ion-row class="menurow">
          <ion-col class="img5">
              <img src="./assets/images/video.png">
              <h4 class="text text-center">VIDEOS</h4>
          </ion-col>
        </ion-row>
        <ion-row class="menurow">
          <ion-col class="img6">
              <img src="./assets/images/contact.png">
              <h4 class="text text-center">CONTACT</h4>
          </ion-col>
        </ion-row>

</ion-grid>
