<div class="price"> <span v-html="goods.sale_price|format"></span> <span class="price-before">￥{{＂这里是价格数据＂}}</span></div>

filters:{  //数据过滤器 format:function(value){  var html,_val;  value =Number(value).toFixed(2);  if(value==0){   value=0;   return html = "￥<span>0</span>";  }else if(value.split('.')[1].substring(1)==0){   value = Number(value).toFixed(1);  }  _val = value.split('.');  return html = '￥<span>'+_val[0]+'</span><em>.'+_val[1]+'</em>'; }}
