前言:前段时间一直都好忙也就好久没有写些东西了,最近手上的事刚好告些段落了,把以前空写的写插件都拿出来分享下吧,希望对大家有些帮助,也希望有高手能帮忙指点下我的写不足和错误,一直以来自己写的东西都是在用,性能方面个人只能尽量靠近问题还很多……真心求指点;
插件简介:执行渐隐等动画效果,可以这个插件为一个附加插件 可以配合前面我发的一个弹出层 等等之类的东西用增加js展示的趣味性,
使用方法:在下面的js代码里面前面写了,大家可以看看直接复制粘贴就可以用了有问题可以联系我</p
JS代码如下 展示方式可以复制下面的HTML查看
/* createByTommy_20110525 emial:@csslife@163.com 用途: 执行渐隐等动画效果 传入参数说明: 1、第一个参数为需要变换对象或ID; 2、第二个参数为一个对象包含: 1)、sty->变换对象需要改变的属性,默认为改变宽度(也可以传非style的属性比如scrollTop等) 2)、curClass->变换对象完成改变后需要添加的当前类,默认为空 3)、maxVal->改变属于的最大值,默认为0(如果curClass为宽高等style属性表示隐藏),当这个要改变的属性值达到时停止动画 4)、effect->执行的动画效果默认为outQuad,如需弹跳效果将其值设置为2 3、最后个参数为可选参数表示当动画执行完毕后运行的回调函数 */ //animation var ani = function(){this.init.apply(this,arguments)} ani.prototype = { _id:function(i){ if(!i) return; return typeof i != "string" && i.nodeType === 1 ? i : document.getElementById(i); }, init:function(e,s,callback){ this.e = this._id(e); this.setInit(s||{}); var maxS = parseInt(this.s.maxVal),speed = maxS==0?Math.max(this.getSty(this.e,this.s.sty),1):maxS/5; this.fun(speed,maxS,callback) }, formula:function(x){ var f; switch(this.s.effect){ case 0: f = "outQuad"; break; case 1: f = "inQuad"; break; case 2: f = "bounce"; break; default: f = "easeInBack"; } this.tween ={ outQuad:function(pos){return Math.pow(pos, 2)},//outQuad inQuad:function(pos){return -(Math.pow((pos-1),2)-1)},//inQuad bounce:function(pos){//bounce if (pos < (1 / 2.75)) { return (7.5625 * pos * pos); } else if (pos < (2 / 2.75)) { return (7.5625 * (pos -= (1.5 / 2.75)) * pos + .75); } else if (pos < (2.5 / 2.75)) { return (7.5625 * (pos -= (2.25 / 2.75)) * pos + .9375); } else { return (7.5625 * (pos -= (2.625 / 2.75)) * pos + .984375); } }, easeInBack:function(pos){var s = 1.70158;return (pos) * pos * ((s + 1) * pos - s);} }; return this.tween[f](x); }, findAry:function(attr){ var rg = ["width","height","top","bottom","left","right","margin","padding"]; for(var z in rg){ if(rg[z]==attr) return true; } return false; }, setInit:function(s){ this.s = { sty:"width", curClass:"", maxVal:0,//效果最大值 effect:1//执行效果 } for(i in s) this.s[i] = s[i]; }, setSty:function(x){ var attr = this.s.sty; if(this.findAry(attr)){ this.e.style[attr] = x + 'px'; var isIE6 = navigator.appVersion.indexOf("MSIE 6")>-1; isIE6&&attr=="top"&&(this.e.style[attr] = x + document.documentElement.scrollTop + 'px'); }else if(attr=="opacity"){ this.s.maxVal===1&&(this.e.style.display = "block"); this.e.style.opacity = x; this.e.style.filter = "alpha(opacity="+x*100+")"; }else{ this.e[this.s.sty] = x } }, getSty:function(e,s){ var val = e.currentStyle?e.currentStyle[s]:document.defaultView.getComputedStyle(e,null)[s]; return parseInt(val)||0; }, fun:function(f,m,callback){ var D = Date,t = new D,e,T = 500,_this = this; return e = setInterval(function() { var z = Math.min(1, (new D - t) / T), c = _this.s.curClass, curC = _this.e.className; _this.setSty( + f + (m - f) * _this.formula(z)); if (z == 1) { if (callback && typeof callback == 'function') callback(); _this.s.maxVal==0&&(_this.e.getAttribute("style"))&&(_this.e.style.display="none"); if(c!=""&&curC.indexOf(c)<0)_this.e.className += c; clearInterval(e); } },10); } }
这是这个js展示的第一个DEMO1:
<!DOCTYPE HTML> <html> <head> <meta charset="gbk"> <title>test</title> <style> div,h6,body{padding:0;margin:0;} div,h6{font:bold 12px/24px 'Tahoma';text-indent:15px;} .car-mod{position:relative;width:200px;} .car-menu{width:200px;background:#c06;cursor:pointer;color:#fff;} .car-box{border:2px solid #c06;width:300px;display:none;} .car-box h6{background-color:#f5f5f5;background-image:-moz-linear-gradient(#f5f5f5,#fff);} .things{border-top:1px solid #ccc;padding:50px 15px;} </style> </head> <body> <div class="car-mod" id="J_car_mod"> <div class="car-menu">购物车</div> <div class="car-box" id="J_car_box"> <h6>我的购物车</h6> <div class="things"></div> </div> </div> <script src="animation.source.js"></script> <script> (function(){ //线上调用这个插件的时候直接调用animation.js这个是压缩了的 var D = document,carMod = D.getElementById("J_car_mod"),carBox = D.getElementById("J_car_box"),carControl=true; //移入显示 carMod.onmouseover = function(even){ var even = even || window.event,target = even.target || even.srcElement; if(target.className=="car-menu"){ !!carControl&&(carObj = new ani(carBox,{maxVal:1,sty:"opacity"},function(){carControl=false;})); carObj = null; } //移出隐藏 this.onmouseout = function(even){ var e = even || window.event, reltg = e.relatedTarget ? e.relatedTarget : e.type == 'mouseout' ? e.toElement : e.fromElement; while (reltg && reltg != this){reltg = reltg.parentNode;} if(reltg != this){ !carControl&&(carObj1 = new ani(carBox,{maxVal:0,sty:"opacity"},function(){carControl=true;})); carObj1 = null; } } } })() </script> </body> </html>
这个是基于前面的那个弹出层的demo版本的效果,这个效果必须复制前面的弹出层的js哦地址为?http://blog.csdn.net/nx8823520/article/details/8059445HTML部分代码如下
<!DOCTYPE HTML> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312"> <title>弹出层事例</title> <style> div{padding:0;margin:0;} .wra{margin:0 auto;width:1000px;overflow:hidden;} .menu{border:1px solid #ccc;background:#000;color:#fff;width:250px;height:30px;font:14px/30px '微软雅黑';text-align:center;text-shadow:1px 1px 2px #f5f5f5;cursor:pointer;} .con{border:1px solid #000;background:#fff;padding:30px;width:500px;height:200px;position:fixed;top:-150%;left:50%;margin:-100px 0 0 -250px;display:none;z-index:999;} .close{display:block;position:absolute;right:10px;top:10px;cursor:pointer;font:bold 14px Arial;-moz-transition:-moz-transform .5s ease-in 0s;} .close:hover{-moz-transform:rotate(360deg);} </style> <style> </style> </head> <body> <div class="wra"> <div id="J_popup" class="menu">点击弹出层</div> <div id="J_popup_con" class="con"> <span id="J_colse" class="close" title="关闭">X</span> 弹出层内容 </div> <script src="popup.js"></script> <script src="animation.source.js"></script> <script> var D = document,m = D.getElementById("J_popup"),con = D.getElementById("J_popup_con"),cl = D.getElementById("J_colse"); new Popup(m,con,cl,{addFun:function(){new ani("J_popup_con",{sty:"top",maxVal:"350",effect:2})},callBack:function(){con.style.display="block";new ani("J_popup_con",{sty:"top",maxVal:"0"})}}) </script> </div> </body> </html>
