你要监听的对象错误了。你要监听的是fixedDom

var fixedDom = document.getElementById('fixed');
fixedDom.addEventListener('scroll',winScroll,false);
function winScroll(e){
        debugger
        if(fixedDom.offsetLeft < document.body.scrollLeft){
    
        };
        if(fixedDom.offsetLeft > document.body.scrollLeft){
    
        };
}
