见下面的工作代码。 为代码说明添加了注释

$(document).ready(function(){
	$(".l-right").click(function(){
	  debugger;
	  $(".menu-overlay").show();
	});
	$(".icon-close").click(function(){
	  debugger;
	  $(".menu-overlay").hide();
	});
  /** SCROLL **/
  $(window).scroll(function() {    
    var scroll = $(window).scrollTop();
     
    if (scroll >= 50) {
        //clearHeader, not clearheader - caps H
        $("header").addClass("sticky");
    }
    else{
      $("header").removeClass("sticky");       
    }
    /* You can adjust on scroll behaviour here */
