      2  
      
       3   
       
        {
   {item.content}}
       4   
       
        删除

wxss代码：

1 .touch-item { 2  font-size: 14px; 3  display: flex; 4  justify-content: space-between; 5  border-bottom:1px solid #ccc; 6  width: 100%; 7  overflow: hidden 8 } 9 .content {10  width: 100%;11  padding: 10px;12  line-height: 22px;13  margin-right:0;14  -webkit-transition: all 0.4s;15  transition: all 0.4s;16  -webkit-transform: translateX(90px);17  transform: translateX(90px);18  margin-left: -90px19 }20 .del {21  background-color: orangered;22  width: 90px;23  display: flex;24  flex-direction: column;25  align-items: center;26  justify-content: center;27  color: #fff;28  -webkit-transform: translateX(90px);29  transform: translateX(90px);30  -webkit-transition: all 0.4s;31  transition: all 0.4s;32 }33 .touch-move-active .content,34 .touch-move-active .del {35  -webkit-transform: translateX(0);36  transform: translateX(0);37 }

js代码：
