动画统计图

帮朋友做了个小功能，顺便分享下。

这是一个统计图，页面加载的时候带有动画效果。

效果图：

html:

<div class="transaction-amount">
    <div class="transaction-amount-con typePage">
        <div class="columnar" id="investAgain">
            <div id="columnar-item-1" class="columnar-item  columnar-item-1">

css:

@charset "utf-8";

.transaction-amount-con,.repayment-amount-con{height:620px;background:#fff;margin-top:30px;}
.repayment-amount-con{margin-bottom:30px;}

.columnar{  padding-left: 10px; position: relative; width:994px;height: 400px; margin:40px auto;}
.columnar-item{ position: relative; float:left; margin-right:20px; width: 63px; height: 100%; }
.columnar-label{ display: block; position: absolute; bottom:-15px; left:-10px; width: 84px; height: 14px; font-size:12px; border:1px solid #000;border-right:none;border-bottom:none;text-align: center; color: #474e5d; }
.columnar-time{display: block;padding-top:18px;}
.columnar-color{background: #9bc5ec; position: absolute; bottom:0; width: 63px; *width: 62px; height: 4%; transition: all 0.4s ease-in-out 0.2s;  }
.columnar-value{ width:58px;height:53px;position: absolute; top: -60px; left:2px; font-size: 14px; line-height:44px;text-align: center;}

.clearfix:before,.clearfix:after{content:"";display:table}
.clearfix:after{clear:both}
.clearfix{*zoom:1}

需要自行先引入jq库。

js:

var els = $('.transaction-amount .columnar-color') ;
            increase(els);        
            function increase(obj){
                //console.log(obj)
                var data = [
                            {'money':1600},
                            {'money':500},
                            {'money':120},
                            {'money':200},
                            {'money':300},
                            {'money':11000},
                            {'money':5000},
                            {'money':20}
                        ]
                var maxNum = 0;
                for(var i in data){
                    maxNum += parseFloat(data[i].money);;
                } 
                for(var i in data){
                    var money = parseFloat(data[i].money);
                    var objChild = $(obj[i]).find(".columnar-value");
                    objChild.html(money);
                    var present = money/maxNum;
                    if(present<0.01){
                        present = 0.01;
                    }
                    //console.log(maxNum)
                    $(obj[i]).css({"height":present*100+"%"});
                }   
            }
