js部分
就這樣咯!/** * Created by Clam on 2016/7/14. */ $(function(){ // 滾動條發生滾動 //noinspection JSUnresolvedFunction $(window).scroll(function(){ /*在這裡做一些事情*/ //noinspection JSValidateTypes var top; //noinspection JSValidateTypes top = $(document).scrollTop(); var menu = $("#menu"); var items = $("#content").find(".item"); var currentId = ""; //當前所在的樓層(item) #id items.each(function () { var m = $(this); var itemTop = m.offset().top; /* console.log(itemTop);*/ if(top > itemTop-200){ currentId = '"#'+ m.attr("id")+'"'; } else { return false; } }) //給相應的樓層a設定class:crrent,取消其他連結的crrent var currentLink = menu.find(".current"); if(currentId && currentLink.attr("href") != currentId){ currentLink.removeClass("current"); menu.find('[href='+ currentId + ']').addClass("current"); } }) });
