封装获取浏览器版本的方法

		function getBrowserVersions() {
	         const userAgent = navigator.userAgent;
	         let version = "";
	         console.log(userAgent)
	         // 判断是否为 Chrome 浏览器
	         if (/Chrome\/(\S+)/.test(userAgent)) {
	             version = userAgent.match(/Chrome\/(\S+)/)[1];
	         }
	         // 判断是否为 Firefox 浏览器
	         else if (/Firefox\/(\S+)/.test(userAgent)) {
	             version = userAgent.match(/Firefox\/(\S+)/)[1];
	         }
	         // 判断是否为 Safari 浏览器
	         else if (/Safari\/(\S+)/.test(userAgent)) {
	             version = userAgent.match(/Version\/(\S+)/)[1];
	         }
	         // 判断是否为 Edge 浏览器
	         else if (/Edg\/(\S+)/.test(userAgent)) {
	             version = userAgent.match(/Edg\/(\S+)/)[1];
	         }
	         // 判断是否为 Internet Explorer 浏览器
	         else if (/MSIE (\S+);/.test(userAgent)) {

     let browserVersions = getBrowserVersions();
