HTML5+React全屏方法实践

实现全屏的条件

• JavaScript实现

• click、mousedown、mouseup事件触发

• 全屏的方法

  • 全屏元素.requestFullscreen(),如果想做到浏览器的兼容，可在requestFullscreen()前加上前缀，火狐为mozRequestFullScreen,chrome为webkitRequestFullScreen()

• 取消全屏的方法

  • 取消全屏元素.cancleFullscreen,兼容办法：在其前加上前缀，火狐为mozCancelFullScreen(),chrome为webkitCancelFullScreen()

一个事例的代码片段

import React from 'react';

class SmartSeller extends React.Component {
	state = {
		data: '点击全屏'
	}
	// 全屏
	requestFullScreen = () => {
        const ele = document.documentElement;
        if (ele.requestFullscreen) {
            ele.requestFullscreen();
        } else if (ele.mozRequestFullScreen) {
            ele.mozRequestFullScreen();
        } else if (ele.webkitRequestFullScreen) {
            ele.webkitRequestFullScreen();
        }
    }
    //退出全屏
    exitFullscreen = () => {
	    if (document.exitFullscreen) {
	      document.exitFullscreen();
	    } else if (document.mozCancelFullScreen) {
	      document.mozCancelFullScreen();
	    } else if (document.webkitCancelFullScreen) {
	      document.webkitCancelFullScreen();
	    }
  	};
  	// button的点击事件，通过state数据判断全屏状态，调用不同的函数
	handleClick = () => {
		const {data} = this.state;
		let result = '';
		if (data === '点击全屏') { // 点击时进入全屏，改变data数据
			this.requestFullScreen();
			result = '退出全屏';
		} else if (data === '退出全屏') { // 点击时退出全屏，变化data数据
			this.exitFullscreen();
			result = '点击全屏';
		}
		this.setState({
			data: result
		})
	}
    render(){
    	const {data} = this.state;
        return(
            {data}
        )
    }

}

export default SmartSeller;
