样式上面是时间轴的呈现效果。

有两种思路进行设计,第一种是时间线的长短跟时间点的位置跟数量都是动态生成的,但是我考虑到时间线的长短动态生成的话,时间点的位置可能不太好控制,尤其是最最后一个时间点跟时间线终点能否连接,加上屏幕大小的变化,还得控制整个时间轴的位置不动,着实有些头疼。然后采取了另外一种,将时间线的长度固定,时间点的数量动态生成,时间点的位置动态控制,这样还是蛮靠谱的,因为最后一个时间点是向右浮动的原因,最后的两个时间点的li层就不允许重合了,不然样式会错乱。

html代码:

<div class="timeLineDiv" v-if="timeLineDataList.length>0">		
	<hr id="timeLineHr">							
	<ul class="timeLineUl">		
		<li class="timeLineli" v-for="(item,index) in timeLineDataList">
			<div class="liTop"></div>
			<div class="liMid"><div><img :src="contextPath+'images/timeLine'+item.color+'.png'"></div></div>
			<div class="liBottom"></div>
		</li>								
	</ul>							
</div>	

css代码:

<style type="text/css">
	.timeLineDiv{
		margin-left:1%;
		margin-top:10px;
		overflow:hidden;
	}
	
	#timeLineHr{
		/*控制时间轴的长度*/			
		width:900px;
		float:left;
		margin-left:90px;
		margin-top:98px;
	}
	
	.timeLineUl{		
		float:left;
		margin-top:-105px;
		list-style:none;
		padding-left:20px;
	}
	.timeLineUl li{
		float:left;
		width:100px;
		text-align:center;
		font-weight:bold; 
	}
	
	li:first-child{
		margin-left:0px;
	}		
	
	.liTop{			
		height:80px;
		overflow:hidden;
	}
			
	.liMid{
		height:34px;
	}
		
	.timeLineUl li .liMid>div{
		background-color:white;
	    width:24px;
	    height:24px;
	    border-radius:12px;
	    float:left;
	    margin-left:38px;
	    margin-top:5px;
	}
	
	.timeLineUl li .liMid>div>img{
		width:28px;
		float:left;
		margin-left:-2px;
		margin-top:-2px;
	}
	
	li>div>p{						
		width:100px;
		float:left;
	}		
</style>

data代码:

data: {	
	timeLineDataList: [],//时间轴展示数据           
    reTime:false,//控制锁。加这个锁是因为选择日期的时候会弹出时间选择的组件,这样会使页面的DOM发生变化,会走Vue的updated方法。updated方法中存在着时间轴样式的控制,所以防止选择日期的时候时间轴样式控制代码的执行,加这个锁。
},

methods中调用加载时间轴代码:

load: function(){	
	//开锁
	vm.reTime = true;
	vm.initTimeLine();
},

加载时间轴:

//加载时间轴--A比今天小:蓝,B等于今天:绿,C大于今天:黄
initTimeLine: function(){

},

时间比较方法:

//时间比较方法
compareTime: function(time){
	return function(a,b){
		var time1 = vm.formatDate(a.time);
		var time2 = vm.formatDate(b.time);
		return time1-time2;
	}					
},

日期类型字符串转时间戳:

//将日期类型字符串 转为1970毫秒
formatDate: function(str){
	return new Date(str.replace(/-/g,'/')).getTime();
},

updated方法中时间轴样式的控制代码:

if(vm.reTime){
	if(vm.timeLineDataList.length>0){	
		//处理li的间距
		var timeLineLi = document.getElementsByClassName("timeLineli");						
		var days = parseInt((vm.formatDate(vm.timeLineDataList[vm.timeLineDataList.length-1].time)-vm.formatDate(vm.timeLineDataList[0].time))/(1000*60*60*24));
		var m = parseInt(900/days);	
		//控制位置																	
		for(var i=1;i<timeLineLi.length;i++){

			var mm = m*day;
			var realw = 0;
			//时间比较
			var f = mm-100;
			var xf = -50-f;
		 	if(xf>0){
				realw = -50;
			}else{

			}						
			timeLineLi[i].style.marginLeft = realw+"px";
		}						
		var hrlW = timeLineLi[timeLineLi.length-1].offsetLeft-timeLineLi[0].offsetLeft;
		var hr = document.getElementById("timeLineHr");

		//控制内容
		for(var i=0;i<timeLineLi.length;i++){

	//关锁

总结:哎,还是让美工画个图简单。。。嘤嘤嘤.
