移动端 动画函数 的 封装_html/css_WEB-ITnose

移动端 单页有时候 制作只用到简单的css3动画即可，我们简单封装一下，没必要引入zepto框架。

上面图片对应的 js

var leftsbox=document.getElementById("leftsbox");	  var boxdiv=leftsbox.getElementsByTagName("div");	  leftsbox.onclick=function(){		   for(var i=0;i
再看看另外一种 常见的 如下图
    
  
    
上面对用的 js 代码
    
var nav=document.querySelector(".nav");			var nava=nav.getElementsByTagName("li");			var content=document.querySelector(".content");			var ulcontent=document.getElementById("ulcontent");			ulcontent.style.width=nav.offsetWidth*nava.length+'px';			for(var i=0;i

基于zepto动画独立出来，语法类似zepto 动画
    
$("#some_element").animate(    {        opacity:0.25,        left:'50px',        color:'#abcdef',        rotateZ:'45deg',        translate3d:'0,10px,0'    },    500,    'ease-out'，function(){  alert('回调'); })
    
改写后 独立与zepto的 动画函数 语法如下
    
transform(element,{ translate3d:'220px,10px,0',left:'1em',opacity:0.2,perspective:'400px', rotateY:'30deg'},duration,'linear',fn,delay);
    
关于兼容性：几乎与zepto一致 ，但是不支持 动画帧 keyframe，个人觉得  keyframe移动端 兼容性不是很好，尤其手机自带的浏览器（原生app 调用 内嵌H5页面，小问题还是蛮多的）；
    
 源码如下 
    
//transform(obj,{translateX:'150px',left:'1em',opacity:0.2,perspective:'400px', rotateY:'40deg'},duration,'linear',fn,delay);               				;(function(window,document,undefined){var prefix = function() {  var div = document.createElement('div');//建立临时DIV容器  var cssText = '-webkit-transition:all .1s;-moz-transition:all .1s; -Khtml-transition:all .1s; -o-transition:all .1s; -ms-transition:all .1s; transition:all .1s;';  div.style.cssText = cssText;  var style = div.style;  var dom='';  if (style.webkitTransition) {	  dom ='webkit';  }  if (style.MozTransition) {    dom='moz';  }   if (style.khtmlTransition) {    dom='Khtml';  }    if (style.oTransition) {    dom='o';  }  if (style.msTransition) {    dom='ms';  }   div=null; ////去掉不必要的数据存储，便于垃圾回收   if(dom){////style.transition 情况	  return {		dom: dom,		lowercase: dom,		css: '-' + dom + '-',		js: dom[0].toUpperCase() + dom.substr(1)	  };   }else{	  return false;   }}();//alert(prefix.js);var transitionEnd=function () {  var el = document.createElement('div');  var transEndEventNames = {    WebkitTransition : 'webkitTransitionEnd',    MozTransition    : 'transitionend',    OTransition      : 'oTransitionEnd',    msTransition    : 'MSTransitionEnd',    transition       : 'transitionend'  };  for (var name in transEndEventNames) {    if (el.style[name] !== undefined) {	    return  transEndEventNames[name] ;    }  }    el=null;  return false;  }();//alert('支持'+transitionEnd);var supportedTransforms = /^((translate|rotate|scale)(X|Y|Z|3d)?|matrix(3d)?|perspective|skew(X|Y)?)$/i; //变形检测var dasherize=function (str) {    return str.replace(/::/g, '/') //将：：替换成/    .replace(/([A-Z]+)([A-Z][a-z])/g, '$1_$2') //在大小写字符之间插入_,大写在前，比如AAAbb,得到AA_Abb    .replace(/([a-z\d])([A-Z])/g, '$1_$2') //在大小写字符之间插入_,小写或数字在前，比如bbbAaa,得到bbb_Aaa    .replace(/_/g, '-') //将_替换成-    .toLowerCase() //转成小写  }var transform=function (obj,properties, duration, ease, callback, delay){			 if (!obj) return;	//参数修正		  if (typeof duration == 'function')      callback = duration, ease = undefined, duration = 400,delay=delay      if (typeof ease == 'function')  //传参为function(properties,duration，callback)        callback = ease, ease = undefined,delay=delay           if (duration) duration = typeof duration == 'number' ? duration :400;		  delay = (typeof delay == 'number') ? delay :0;	       	//参数修正	var nowTransition=prefix.js+'Transition';	var nowTransform=prefix.js+'Transform';	var prefixcss=prefix.css;	if(!prefix.js){		nowTransition='transition';	    nowTransform='transform';		prefixcss='';  //-webkit-transition >> transition  	}		var transitionProperty, transitionDuration, transitionTiming, transitionDelay;//过渡	var key, cssValues = {}, cssProperties, transforms = "";    // transforms 变形   cssValues设置给DOM的样式	var transform;     //变形    var cssReset = {};	var css='';	var cssProperties = [];			  transform = prefixcss + 'transform';       //变形    cssValues[transform]	  cssReset[transitionProperty = prefixcss + 'transition-property'] =	  cssReset[transitionDuration = prefixcss + 'transition-duration'] =	  cssReset[transitionDelay    = prefixcss + 'transition-delay'] =	  cssReset[transitionTiming   = prefixcss + 'transition-timing-function']='';		      // CSS transitions	     for (key in properties){       //如果设置 的CSS属性是变形之类的       if (supportedTransforms.test(key)) transforms += key + '(' + properties[key] + ') '       else cssValues[key] = properties[key], cssProperties.push(dasherize(key))	 } //for end        if (transforms) cssValues[transform] = transforms, cssProperties.push(transform)	          if (duration > 0 && typeof properties === 'object') {         cssValues[transitionProperty] = cssProperties.join(', ')         cssValues[transitionDuration] = duration + 'ms'         cssValues[transitionTiming] = (ease || 'linear')		 cssValues[transitionDelay] = delay + 'ms'       }                      for(var attr in cssValues){				  css += dasherize(attr) + ':' + cssValues[attr]+ ';'							  }						obj.style.cssText=obj.style.cssText+css;						    	  		if(!callback){return } //没有回调函数 return	    var fired = false;		var handler = function () {				 callback && callback.apply(obj,arguments);				 fired=true;				  				if(obj.removeEventListener)				 obj.removeEventListener(transitionEnd,arguments.callee,false)				        };          		  if(obj.addEventListener){	       obj.addEventListener(transitionEnd, handler,false);		  }				  if(!transitionEnd||duration    
唯一的缺点  scrollTop 缓动不支持； 这里有个简易的  函数 类似jquery  语法几乎一样

tops

上图相关js

  document.getElementById("gpTop").onclick=function(e){              var  that=this;                 startMove(that,{"scrollTop":0},function(){                    that.innerHTML='到顶了';                     });  //width: 206px; height: 101px; opacity: 0.3;                }                                                var inner=document.getElementById("inner");                var inlione=inner.getElementsByTagName("li");                var box=document.querySelectorAll(".boxs");                                for(var i=0;i
如果通过原生js  获取  jquey的offset().top  的值呢 如下  这里
    
  var getOffest=function (obj){var top=0,left=0;if(obj){ while(obj.offsetParent){      top += obj.offsetTop;      left += obj.offsetLeft;      obj = obj.offsetParent;   } }  return{  top : top,  left : left  }}
    
 startMove基于 requestAnimationFrame  兼容ie8+    
    
语法如下
    
startMove(element,{"left":1300,"opacity":90},2000,'easeOut',function sa(){			  console.log('回调函数');			 });  //  width: 201px; height: 135px; opacity: 0.8;  只有宽是对的  其他未达到目标
