用html5 js实现浏览器全屏

项目中需要将后台浏览器的窗口全屏，也就是我们点击一个按钮要实现按F11全屏的效果。 在HTML5中,W3C制定了关于全屏的API，就可以实现全屏幕的效果，也可以让页面中的图片，视频等全屏目前只有google chrome 15 +, safri5.1+,firfox10+,IE11支持。


全屏

1. var docElm = document.documentElement;
   
2. 
   
3. //W3C
   
4. 
   
5. if (docElm.requestFullscreen) {
   
6. 
   
7. docElm.requestFullscreen();
   
8. 
   
9. }
   
10. 
    
11. //FireFox
    
12. 
    
13. else if (docElm.mozRequestFullScreen) {
    
14. 
    
15. docElm.mozRequestFullScreen();
    
16. 
    
17. }
    
18. 
    
19. //Chrome等
    
20. 
    
21. else if (docElm.webkitRequestFullScreen) {
    
22. 
    
23. docElm.webkitRequestFullScreen();
    
24. 
    
25. }
    
26. 
    
27. //IE11
    
28. 
    
29. else if (elem.msRequestFullscreen) {
    
30. 
    
31. elem.msRequestFullscreen();
    
32. 
    
33. }

复制代码

退出全屏

1. if (document.exitFullscreen) {
   
2. 
   
3. document.exitFullscreen();
   
4. 
   
5. }
   
6. 
   
7. else if (document.mozCancelFullScreen) {
   
8. 
   
9. document.mozCancelFullScreen();
   
10. 
    
11. }
    
12. 
    
13. else if (document.webkitCancelFullScreen) {
    
14. 
    
15. document.webkitCancelFullScreen();
    
16. 
    
17. }
    
18. 
    
19. else if (document.m**itFullscreen) {
    
20. 
    
21. document.m**itFullscreen();
    
22. 
    
23. }

事件监听

1. document.addEventListener("fullscreenchange", function () {
   
2. 
   
3. fullscreenState.innerHTML = (document.fullscreen)? "" : "not ";}, false);
   
4. 
   
5. 
   
6. 
   
7. document.addEventListener("mozfullscreenchange", function () {
   
8. 
   
9. fullscreenState.innerHTML = (document.mozFullScreen)? "" : "not ";}, false);
   
10. 
    
11. 
    
12. 
    
13. document.addEventListener("webkitfullscreenchange", function () {
    
14. 
    
15. fullscreenState.innerHTML = (document.webkitIsFullScreen)? "" : "not ";}, false);
    
16. 
    
17. document.addEventListener("msfullscreenchange", function () {
    
18. 
    
19. fullscreenState.innerHTML = (document.msFullscreenElement)? "" : "not ";}, false);

全屏样式设置


在浏览器全屏的使用我们还可以进行样式设置

1. html:-moz-full-screen {
   
2. 
   
3. background: red;
   
4. 
   
5. }
   
6. 
   
7. 
   
8. 
   
9. html:-webkit-full-screen {
   
10. 
    
11. background: red;
    
12. 
    
13. }
    
14. 
    
15. 
    
16. 
    
17. html:fullscreen {
