用html5 js实现点击一个按钮达到浏览器全屏效果
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googlechrome15+,safri5.1+,firfox10+,IE11支持
全屏
vardocElm=document.documentElement;
//W3C
if(docElm.requestFullscreen){
docElm.requestFullscreen();
}
//FireFox
elseif(docElm.mozRequestFullScreen){
docElm.mozRequestFullScreen();
}
//Chrome等
elseif(docElm.webkitRequestFullScreen){
docElm.webkitRequestFullScreen();
}
//IE11
elseif(elem.msRequestFullscreen){
elem.msRequestFullscreen();
}
退出全屏
if(document.exitFullscreen){
document.exitFullscreen();
}
elseif(document.mozCancelFullScreen){
document.mozCancelFullScreen();
}
elseif(document.webkitCancelFullScreen){
document.webkitCancelFullScreen();
}
elseif(document.msExitFullscreen){
document.msExitFullscreen();
}
事件监听
document.addEventListener("fullscreenchange",function(){
fullscreenState.innerHTML=(document.fullscreen)?"":"not";},false);
document.addEventListener("mozfullscreenchange",function(){
fullscreenState.innerHTML=(document.mozFullScreen)?"":"not";},false);
document.addEventListener("webkitfullscreenchange",function(){
fullscreenState.innerHTML=(document.webkitIsFullScreen)?"":"not";},false);
document.addEventListener("msfullscreenchange",function(){
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
html:-moz-full-screen{
background:red;
}
html:-webkit-full-screen{
background:red;
}
html:fullscreen{
background:red;
}
