前端代码：
1 <!--导入数据开始--> 2 <div class='container-fluid' style="color: white;"> 3 <div class='row-fluid' id='content-wrapper' style="display: block;"> 4 <div class="modal-add hide fade in" id="modal-addsubject" role="dialog" aria-hidden="false" style="display:none;height:20%;"> 5 <div class="modal-header" style="border-bottom:0;"> 6 <button class="close" data-dismiss="modal" type="button" style="color:white;opacity:1;">×</button> 7 <h3 style="color: white;"><div class="icon-edit"></div> 导入数据</h3> 8 </div> 9 <div class="modal-body" id="add_modify_subject"> 10 <form id='upload' enctype='multipart/form-data' action='' method='post' style='text-align:left;'> 11 <input name="fileBuildInfo1" id='fileBuildInfo1' class='big' type='file' mutiple="multiple" /> 12 </form> 13 </div> 14 <div class="modal-footer" style="border-top:0;box-shadow:none;-webkit-box-shadow:none;"> 15 <button class="btn btn-primary" style="background-color:#09abeb;border-style:solid;border-width:0.2px;border-color:#7cf8ff;" onclick="uploadFile()"><i class="icon-save"></i> 保存</button> 16 </div> 17 </div> 18 </div> 19 </div> 20 <!--导入数据结束-->
js方法：
1 //上传excel数据文件 2 function uploadFile(){ 3 $('#upload').ajaxSubmit({ 4 url: "/UploadFiles/uploadexcelfile", 5 data: { 6 'filetype': "excel表格", 7 'type':case_type 8 }, 9 cache: false, 10 dataType: 'json', 11 success: function(data) { 12 if (data.result == "success") { 13 layer.msg('上传成功！', { 14 icon: 1 15 }); 16 } else { 17 layer.msg('上传失败！', { 18 icon: 2 19 }); 20 } 21 }, 22 error: function() { 23 layer.msg('错误！', { 24 icon: 2 25 }); 26 } 27 }); 28 if(case_type=="ms"){ 29 select_btn(1); 30 }else if(case_type=="xs"){ 31 select_btn(2); 32 }else{ 33 select_btn(3); 34 } 35 $("#modal-addsubject").modal("hide"); 36 }
