Showing Image in full screen - using JavaScript/HTML5

google-chrome, html, internet-explorer, javascript

Solution

So, found the solution after some trial...

The solution is in the style section: - width, height, margin are set to 'auto', - but also marked as '!important' - this allows you to override the inline styling of the image on the webpage - when in fullscreen mode.

<!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>

Problem

I have an image on a web page. When I click on it, it should display full screen. I have the following code: ``` <!doctype html> <html> <head> <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> Click Image to display Full Screen...</br> <img id="theImage" style="width:400px; height:auto;" src="pic1.jpg" onClick="makeFullScreen()"></img> </body> </html> ``` Problem I am facing - In full screen mode: - The image displays in small size (i.e same as the size on browser page), not its original size - on all browsers. - In IE - The image is not centered, it shows up on left side of the full screen (why not centered?). In Chrome - it is centered - as desired.
