我们先来分析分析要制作Excel导出功能的思路
从功能上
1.导出全部
导出全部没有条件
2.导出部分
导出部分是特殊的导出全部,就是加条件进行筛选
步骤一
我们做Excel功能肯定要用到NPOI这个包,我们直接用Nuget包管理进行把NPOI的东西加进去
步骤二
在controller中把导出excel方法写好,然后调用sevice层中对数据的筛选
步骤三
在html中,就是前端中进行调用
那好,我们来看看代码是怎么实现的
步骤一直接省略
步骤二的代码实现功能
导出全部

导出全部的数据:
var list = _iAssetManageService.GetAssetManageModel("", "", "", "", "", 0, "");
参数都是空或0
导出部分的数据
var list = _iAssetManageService.GetAssetManageModel(search, startdate, enddate, startdate1, enddate1, radiotype, users);其中,service层中对数据进行筛选我们就不细说了 就是取数据把取得的数据进行改变而已
步骤三就是去调用咯
调用就是用对应的方法,把对应的参数传过去就行了
导出全部
Html代码
<button class="btn btn-success btn-sm btn-export" onclick="exportexcelall();">导出全部到Excel</button>
对应的js
function exportexcelall() { location.href = '@Url.Action("ExportIndex")'; }
导出部分
Html代码
<button class="btn btn-success btn-sm btn-export" onclick="exportexcelpart();">导出筛选后到Excel</button>
对应的js
function exportexcelpart() { var search = $('#txtSearch').val().trim(); var startdate = $('.start-date').val().trim(); var enddate = $('.end-date').val().trim(); var startdate1 = $('.start-date1').val().trim(); var enddate1 = $('.end-date1').val().trim(); var radiotype = $('input[name="inlineRadioOptions"]:checked').val(); var users = $('.users-id').val(); location.href = '@Url.Action("ExportIndexpart")' + '?search=' + search + '&startdate=' + startdate + '&enddate=' + enddate + '&startdate1=' + startdate1 + '&enddate1=' + enddate1 + '&radiotype=' + radiotype + '&users=' + users; }
