使用单一功能全屏制作多张图片

Question

我在 Stack Overflow 上的一个问题中发现了一个完整制作图像的代码screen.But该代码仅适用于一张图像。

<!doctype html>
<html>
  <head>
     <style>
      .fullscreen:-webkit-full-screen {
      width: auto !important;
      height: auto !important;
      margin:auto !important;
  }
     .fullscreen:-moz-full-screen {
      width: auto !important;
      height: auto !important;
      margin:auto !important;
  }
     .fullscreen:-ms-fullscreen {
      width: auto !important;
      height: auto !important;
      margin:auto !important;
  }     
     </style>
     <script>
        function makeFullScreen() {
         var divObj = document.getElementById("theImage");
       //Use the specification method before using prefixed versions
      if (divObj.requestFullscreen) {
        divObj.requestFullscreen();
      }
      else if (divObj.msRequestFullscreen) {
        divObj.msRequestFullscreen();               
      }
      else if (divObj.mozRequestFullScreen) {
        divObj.mozRequestFullScreen();      
      }
      else if (divObj.webkitRequestFullscreen) {
        divObj.webkitRequestFullscreen();       
      } else {
        console.log("Fullscreen API is not supported");
      } 

    }
     </script>

  </head>
  <body>
    Hello Image...</br>

    <img id="theImage" style="width:400px; height:auto;"  class="fullscreen" src="pic1.jpg" onClick="makeFullScreen()"></img>

  </body>
</html>

能否将此函数转换为适用于多幅图像（而不是为每幅图像创建一个函数）。

Answer 1

这只需将 onClick 处理程序添加到多个图像元素并将事件参数分配给每个函数调用即可。

<img src="picA.jpg" onClick="makeFullScreen(event)">
<img src="picB.jpg" onClick="makeFullScreen(event)">
<img src="picC.jpg" onClick="makeFullScreen(event)">

在 makefullScreen 回调函数中，您可以获得触发点击事件的元素 - 因此是您的图像 - 并使用现有代码将其全屏显示。

function makeFullScreen(e) {
  var divObj = e.currentTarget;
  //Use the specification method before using prefixed versions
  if (divObj.requestFullscreen) {
    divObj.requestFullscreen();
  } else if (divObj.msRequestFullscreen) {
    divObj.msRequestFullscreen();
  } else if (divObj.mozRequestFullScreen) {
    divObj.mozRequestFullScreen();
  } else if (divObj.webkitRequestFullscreen) {
    divObj.webkitRequestFullscreen();
  } else {
    console.log("Fullscreen API is not supported");
  }
}

使用单一功能全屏制作多张图片

Make multiple images in full screen with a single function

javascript

html

css

fullscreen
