HTML代码
<div id="credential-photo" class="mui-input-row" style="height: 60px;padding-top: 8px; display: none;"> <label><i>* </i>证书照片</label> <div> <div id="userfile" style="display: inline-block;"> </div> <a id="addfile" href="#picture"><img src="img/toggle-expand.png"/></a> </div> </div> <div id="picture" class="mui-popover mui-popover-action mui-popover-bottom"> <ul class="mui-table-view"> <li class="mui-table-view-cell"> <a id="getImage" href="#">拍照</a> </li> <li class="mui-table-view-cell"> <a id="getAlbum" href="#">相册</a> </li> </ul> <ul class="mui-table-view"> <li class="mui-table-view-cell"> <a href="#picture"><b>取消</b></a> </li> </ul> </div>
然后是简单的CSS
#userfile>.img-item{
position: relative;
margin: 0;
padding: 0;
display: inline-block;
}
#userfile>.img-item>.img-close{
position: absolute;
right: 0px;
background-color: red;
display: inline-block;
14px;
height: 14px;
border-radius: 7px;
color: #FFFFFF;
text-align: center;
font-size: 14px;
font-weight: bold;
cursor: pointer;
}
