            var setTimelineWidth;//this is going to be your function based on device
            function IsMobile() {
              var Uagent = navigator.userAgent||navigator.vendor||window.opera;

      if(typeof window !== 'undefined'){
            var ua = 'navigator' in window && 'userAgent' in navigator &&
                navigator.userAgent.toLowerCase() || '';
        }     
       var judge = {
                isMobile: function () {
                            return !!ua.match(/(iPhone|iPod|android|ios|iPad|windows 
                phone|tablet)/i);
                        },
                        isPc: function () {
                            return !judge.isMobile();
                        }
            }           
    
            if(judge.isMobile()){
            //mobile
            }else(judge.isPc()){
            //pc
            }
    

    另外,我还写了一个NPM软件包用于判断,https://github.com/hawx1993/judge
