I have been making pages for two years. I have also done a lot of page effects, which are simple and complex. Today I will share a special effect on navigation scrolling to content.
We usually do navigation and scroll to the content through the anchor. After a click, we jump directly to the content without any scrolling effect, and there will be a "little tail" at the end of the url link ", today, I will introduce a special rolling effect made by jquery, which can set the rolling speed and there is no "Small Tail" on the url link ".
Html:
<!DOCTYPE HTML>Jquery. scrollto. js:
jQuery.getPos = function (e){ var l = 0; var t = 0; var w = jQuery.intval(jQuery.css(e,'width')); var h = jQuery.intval(jQuery.css(e,'height')); var wb = e.offsetWidth; var hb = e.offsetHeight; while (e.offsetParent){ l += e.offsetLeft + (e.currentStyle?jQuery.intval(e.currentStyle.borderLeftWidth):0); t += e.offsetTop + (e.currentStyle?jQuery.intval(e.currentStyle.borderTopWidth):0); e = e.offsetParent; } l += e.offsetLeft + (e.currentStyle?jQuery.intval(e.currentStyle.borderLeftWidth):0); t += e.offsetTop + (e.currentStyle?jQuery.intval(e.currentStyle.borderTopWidth):0); return {x:l, y:t, w:w, h:h, wb:wb, hb:hb};};jQuery.getClient = function(e){ if (e) { w = e.clientWidth; h = e.clientHeight; } else { w = (window.innerWidth) ? window.innerWidth : (document.documentElement && document.documentElement.clientWidth) ? document.documentElement.clientWidth : document.body.offsetWidth; h = (window.innerHeight) ? window.innerHeight : (document.documentElement && document.documentElement.clientHeight) ? document.documentElement.clientHeight : document.body.offsetHeight; } return {w:w,h:h};};jQuery.getScroll = function (e) { if (e) { t = e.scrollTop; l = e.scrollLeft; w = e.scrollWidth; h = e.scrollHeight; } else { if (document.documentElement && document.documentElement.scrollTop) { t = document.documentElement.scrollTop; l = document.documentElement.scrollLeft; w = document.documentElement.scrollWidth; h = document.documentElement.scrollHeight; } else if (document.body) { t = document.body.scrollTop; l = document.body.scrollLeft; w = document.body.scrollWidth; h = document.body.scrollHeight; } } return { t: t, l: l, w: w, h: h };};jQuery.intval = function (v){ v = parseInt(v); return isNaN(v) ? 0 : v;};jQuery.fn.ScrollTo = function(s) { o = jQuery.speed(s); return this.each(function(){ new jQuery.fx.ScrollTo(this, o); });};jQuery.fx.ScrollTo = function (e, o){ var z = this; z.o = o; z.e = e; z.p = jQuery.getPos(e); z.s = jQuery.getScroll(); z.clear = function(){clearInterval(z.timer);z.timer=null}; z.t=(new Date).getTime(); z.step = function(){ var t = (new Date).getTime(); var p = (t - z.t) / z.o.duration; if (t >= z.o.duration+z.t) { z.clear(); setTimeout(function(){z.scroll(z.p.y, z.p.x)},13); } else { st = ((-Math.cos(p*Math.PI)/2) + 0.5) * (z.p.y-z.s.t) + z.s.t; sl = ((-Math.cos(p*Math.PI)/2) + 0.5) * (z.p.x-z.s.l) + z.s.l; z.scroll(st, sl); } }; z.scroll = function (t, l){window.scrollTo(l, t)}; z.timer=setInterval(function(){z.step();},13);};Call method:
$ (Id). ScrollTo (speed); // id indicates the id of the content to jump to. speed indicates the rolling speed. The larger the value, the slower the scrolling speed.
