用html5js实现浏览器全屏

时间:2021-07-01 10:21:17 帮助过:16人阅读

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. //W3C

  3. if (docElm.requestFullscreen) {

  4. docElm.requestFullscreen();

  5. }

  6. //FireFox

  7. else if (docElm.mozRequestFullScreen) {

  8. docElm.mozRequestFullScreen();

  9. }

  10. //Chrome等

  11. else if (docElm.webkitRequestFullScreen) {

  12. docElm.webkitRequestFullScreen();

  13. }

  14. //IE11

  15. else if (elem.msRequestFullscreen) {

  16. elem.msRequestFullscreen();

  17. }


退出全屏


  1. if (document.exitFullscreen) {

  2. document.exitFullscreen();

  3. }

  4. else if (document.mozCancelFullScreen) {

  5. document.mozCancelFullScreen();

  6. }

  7. else if (document.webkitCancelFullScreen) {

  8. document.webkitCancelFullScreen();

  9. }

  10. else if (document.m**itFullscreen) {

  11. document.m**itFullscreen();

  12. }


事件监听


  1. document.addEventListener("fullscreenchange", function () {

  2. fullscreenState.innerHTML = (document.fullscreen)? "" : "not ";}, false);



  3. document.addEventListener("mozfullscreenchange", function () {

  4. fullscreenState.innerHTML = (document.mozFullScreen)? "" : "not ";}, false);



  5. document.addEventListener("webkitfullscreenchange", function () {

  6. fullscreenState.innerHTML = (document.webkitIsFullScreen)? "" : "not ";}, false);

  7. document.addEventListener("msfullscreenchange", function () {

  8. 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. background: red;

  3. }



  4. html:-webkit-full-screen {

  5. background: red;

  6. }



  7. html:fullscreen {

  8. background: red;

  9. }
