前端实体列表页面框架修改
前端页面为DemoObjectController的Index方法对应的Index.cshtml视图，页面结构修改参考UserController的Index方法对应的Index.cshtml,分为两大块，查询表单和datatable列表。
查询表单部分包括简单查询和高级查询，具体参考下面代码，有注释说明
@using EDU.SIS.Web.Areas.app.Startup
@using EDU.SIS.Authorization
@{
ViewBag.CurrentPageName = appPageNames.Common.Demo;
}
@section Styles
{
<link rel="stylesheet" href="/view-resources/Areas/app/Views/Demo/index.css" />
}
@section Scripts
{
<script src="/view-resources/Areas/app/Views/Demo/index.js" ></script>
}

编写js代码实现数据列表，实现列表功能,分页，排序功能
-
- 首先需要获取datatable对象，并获取后台接口服务，还有权限列表
//数据列表对象
var _$demoObjectTable = $("#DemoObjectTable");
//后台接口服务对象
var _demoObjectService = abp.services.app.demoObject;
//权限列表
var _permissions = {
create: abp.auth.hasPermission('Pages.Demo.Create'),
edit: abp.auth.hasPermission('Pages.Demo.Create'),
'delete': abp.auth.hasPermission('Pages.Demo.Create')
};-
- 初始化dataTable数据，并添加操作方法列，调用
_demoObjectService.getAll方法获取后台数据，并添加分页，过滤排序参数的传递
- 初始化dataTable数据，并添加操作方法列，调用
var dataTable = _$demoObjectTable.DataTable({
paging: true, //分页操作栏
serviceSide: true, //服务端进行分页处理
processsing: true, //处理数据等待提示
listAction: {
ajaxFunction: _demoObjectService.getAll,//获取后台数据
inputFilter: function () { //输入参数，过滤选项
return {
filter: $("#DemoObjectTableFilter").val(),
nameFilter: $("#NameFilterId").val()
};
}
},
columnDefs: [
{
className: 'control responsive',
orderable: false,
render: function () {
return '';
},
targets: 0
},
{
targets: 1,//数据列顺序值
data: null,//数据内容体
orderable: false,//是否允许排列
autoWidth: false,//自动列宽
defaultContent: '',//默认显示内容
rowAction: {
text: '<i class="fa fa-cog"></i> ' + app.localize('Actions') + ' <span class="caret"></span>',
items: [
{
text: app.localize('View'),
visible: function () { return true;}, //注意这里visible必须是函数，不能是简单的true或false
action: function () {
console.log('view'); //这里只是占位，下一节实现具体功能
}
},
{
text: app.localize('Edit'),
visible: function () {
return _permissions.edit; //根据权限决定是否显示改操作方法
},
action: function () {
console.log('edit');
}
},
{
text: app.localize('Delete'),
visible: function () {
return _permissions.delete;
},
action: function () {
console.log('delete');
}
}
]
}
},
{
targets: 2,
orderable: false,
data:"demoObject.name"
},
{
targets: 3,
data: "demoObject.age"
},
{
targets: 4,
data: "demoObject.isVip",
render: function (isVip) { //自定义显示数据
if (isVip) {
return '<div class="text-center"><i class="fa fa-check-circle" title="True"></i></div>'
}
return '<div class="text-center"><i class="fa fa-times-circle" title="False"></i></div>'
}
},
{
targets: 5,
data: "demoObject.endDateTime",
render: function (endDateTime) {
if (endDateTime) {
return moment(endDateTime).format('YYYY-MM-DD HH:mm:ss'); //时间格式化
}
return "";
}
}
]
});
js代码实现查询功能
接下来是处理查询按钮点击事件，和高级查询的显示和隐藏
//刷新数据
function getDemoObject() {
dataTable.ajax.reload();
}
//查询按钮事件
$("#GetDemoObjectButton").click(function (e) {
e.preventDefault();
getDemoObject();
});
//显示高级查询
$('#ShowAdvancedFiltersSpan').click(function () {
$('#ShowAdvancedFiltersSpan').hide();
$('#HideAdvancedFiltersSpan').show();
$('#AdvacedAuditFiltersArea').slideDown();
});
//隐藏高级查询
$('#HideAdvancedFiltersSpan').click(function () {
$('#HideAdvancedFiltersSpan').hide();
$('#ShowAdvancedFiltersSpan').show();
$('#AdvacedAuditFiltersArea').slideUp();
});效果：
