一、导入
1、js
/*导入*/
upload.render({
//允许上传的文件后缀
elem: '#uploadEventFile'
,url: '/billopenb/importExcel'
,accept: 'file'
,exts: 'xlsx|xls'
,method: 'post'
,field: 'file'
,data: {
istax: function(){
var istax=$('input:radio[name="tax"]:checked').val();
if(istax=='含税'){
sfhs=1;
}else if(istax=='不含税'){
sfhs=0;
}
return sfhs;
}
}
,before: function(){
}
,headers:{"token":localStorage.token}
,done: function(res) {
if (res.success == true) {
console.log("导入成功");
//导入成功,先清本地数据
dataList[curId].splice(0,dataList[curId].length);
dataList[curId].push(JSON.parse(JSON.stringify(trData)));
//list=list.concat(res.body.vtBillopenb)
list = res.body.vtBillopenb;
// var list = res.body.vtBillopenb;
for (var i = 0;i<list.length;i++) {
list[i].rowno = i+1;
// list[i].taxrate = list[i].taxrate;
}
//如果子表>8行主表清单标识为1,否则清单标识为0
initForm(list);
dataList[curId] = list;
sessionStorage.setItem('spList',JSON.stringify(list));
}else{
layer.alert(res.msg);
}
}
,error: function(res){
layer.msg('上传失败,请您检查该文件格式/模板是否正确。');
}
})
2、java
controller
@ResponseBody
@RequestMapping(value = "billopenb/importExcel", method = RequestMethod.POST)
public AjaxJson importExcel(@RequestParam("file") MultipartFile file,
@ApiParam("含税标识 0否 1是") @RequestParam(required = true, value = "istax") String istax) throws Exception {
List<Map<String, Object>> result = vtbillopenBService.readExcelFile(file, istax);
return AjaxJson.ok("导入成功!").put("vtBillopenb", result);
}
