ASP.net教程之vs2017 + miniUI + dapper 添加、修改、删除

A、数据库表引用先前建立的company 公司信息表。

B、建立文件：

views 》 Home 》 Company.cshtml（新建文件） ，代码如下（直接复制即可）

Layout = Layout = "~/Views/Shared/_Layout.cshtml"; ;

}

<tr>

</td>

</td>

</tr>

</table>

</div>

<div id="datagrid1" class="mini-datagrid" style="width:100%;height:280px;" allowResize="true" pageSize="10"

url="/Home/CompanyList" idField="id" multiSelect="true" pagesize="20" showpager="true">

</div>

mini.parse();

var grid = mini.get("datagrid1");

grid.load();

grid.on("drawcell", function (e) {

var record = e.record,

column = e.column,

field = e.field,

value = e.value;

//action列，超连接操作按钮

if (column.name == "action") {

e.cellStyle = "text-align:center";

e.cellHtml = '<a class="mini-button" style="width:60px;" href="javascript:edit(\'' + record.id + '\')">修改</a>  '

+ '<a class="mini-button" style="width:60px;" href="javascript:del(\'' + record.id + '\')" >删除</a>'

}

});

function search() {

var key = mini.get("key").value;

grid.load({ key: key });

}

$("#key").bind("keydown", function (e) {

if (e.keyCode == 13) {

search();

}

});

function del(rowid) {

if (rowid.length > 0) {

if (confirm("确定删除选中记录？")) {

grid.loading("操作中，请稍后......");

$.ajax({

url: "/Home/Delete?id=" + rowid,

type: "post",

success: function (text) {

grid.reload();

error: function () {

}

});

}

} else {

alert("请选中一条记录");

}

//添加、修改

function edit(rowid) {

mini.open({

targetWindow: window,

url: "/Home/CompanyEdit?Id=" + rowid,

title: "设置条件", width: 800, height: 600,

onload: function () {

var iframe = this.getIFrameEl();

var data = { action: "new" };

iframe.contentWindow.OpenContext = { parent: window, popwin: this };

ondestroy: function (action) {

loading();

grid.reload();

}

});

}

//新建

function add() {

mini.open({

targetWindow: window,

url: "/Home/CompanyEdit",

title: "添加菜单", width: 700, height: 300,

onload: function () {

var iframe = this.getIFrameEl();

var data = { action: "new" };

loading();

iframe.contentWindow.OpenContext = { parent: window, popwin: this };

ondestroy: function (action) {

grid.reload();

}

});

}

function loading() {

mini.mask({

el: document.body,

cls: 'mini-mask-loading',

html: '加载中...'

});

setTimeout(function () {

mini.unmask(document.body);

}, 1000);

}

</script>

views 》 Home 》CompanyEdit.cshtml（新建文件） ，代码如下（直接复制即可）

@model MiniUi_Dapper.Controllers.Company

ViewBag.Title = "CompanyEdit";

Layout = "~/Views/Shared/_Layout.cshtml";

}

<tr>

</tr>

<tr>

</tr>

<tr>

</tr>

</table>

</div>

</form>

mini.parse();

var form = new mini.Form("form1");

function SaveData() {

var form = new mini.Form("#form1");

var data = form.getData(); //获取表单多个控件的数据

//var json = mini.encode(data); //序列化成JSON

$.ajax({

url: "/Home/CompanySave",

type: "post",

data: data,

success: function (text) {

//alert("提交成功，返回结果:" + text);

//grid.reload();

CloseWindow("提交成功");

}

});

}

function GetData() {

var o = form.getData();

return o;

}

function CloseWindow(action) {

if (action == "close" && form.isChanged()) {

if (confirm("数据被修改了，是否先保存？")) {

return false;

}

if (window.CloseOwnerWindow) return window.CloseOwnerWindow(action);

else window.close();

}

function onOk(e) {

SaveData();

}

function onCancel(e) {

CloseWindow("cancel");

}

</script>
