前言
近几年基本都是开发SPA
应用,朋友找我帮忙做一个简单的后台管理的模块,是传统的ASP.NET
WEB
页面,不过我这次还是写独立的前端界面的,只是会基于他们系统使用的框架去开发(jq+bootstrap
)。
任务
- 列表页(搜索、表格展示、分页)
- 表单提交页(新增/编辑)
技术框架
例子:https://blog.csdn.net/weixin_...
开发笔记
原项目用的是v3
版本的bootstrap
表格
原项目中表格有用bootstrapTable
插件(功能看着挺齐全),由于其官网例子很多加载不出来(控制台报错),自己对它不熟悉,且任务时间紧担心用了后面要扩展不方便,我就没用它的。
表格我是请求数据后,直接用art-template模版引擎去渲染,简单的示例界面如下:
界面:
<!DOCTYPE html>
<html lang="en">

<meta charset="UTF-8">

<title>art-Templat例子</title>
<script src="./lib/art-template/template-web.js"></script>
<style>
table {
border-collapse: collapse;
border-spacing: 0;
}
table .th {
background-color: #f5f5f5;
font-size: 12px;
font-weight: bold;
}
table tr {
border-top: 1px solid #dfdfdf;
}
table tr:last-child {
border-bottom: 1px solid #dfdfdf;
}
table tr td {
padding: 4px 6px;
font-size: 12px;
}
</style>
</head>
<body>
<!--列表-->
<table class="table">
<tbody id="table-tbody">
</tbody>
</table>
<!--列表内容模版-->
<script id="tpl-table-tbody" type="text/html">
<tr class="th">
<td>ID</td>
<td>订单号</td>
<td>收货人</td>
<td>手机号</td>
<td>状态</td>
<td>创建人</td>
<td>创建时间</td>
</tr>
{{each list}}
<tr>
<td>{{$value.id}}</td>
<td>{{$value.orderNo}}</td>
<td>{{$value.receiver}}</td>
<td>{{$value.phone}}</td>
<td>{{$value.status}}</td>
<td>{{$value.creator}}</td>
<td>{{$value.createTime}}</td>
</tr>
{{/each}}
</script>
</body>
</html>
对应JS:
var html = template('tpl-table-tbody', {
list: [{
id: 'XK001',
orderNo: 'ORD202205180001',
receiver: '张三',
phone: '13512341234',
status: '待发货',
creator: '管理员',
createTime: '2022-03-20 15:30:22'
}, {
id: 'XK002',
orderNo: 'ORD202205180002',
receiver: '张三',
phone: '13512341234',
status: '已完成',
creator: '管理员',
createTime: '2022-03-02 18:30:22'
}, {
id: 'XK003',
orderNo: 'ORD202205180003',
receiver: '张三',
phone: '13512341234',
status: '待收货',
creator: '管理员',
createTime: '2022-03-16 20:30:22'
}]
});
document.getElementById('table-tbody').innerHTML = html;
分页
由于表格是单独渲染了,就得再单独考虑分页。
想要的效果:
我试了一下boostrapPagination
,效果和想要的差别有点大,如下图所示,页数很多时没有考虑...
的展示,且首尾页时默认隐藏头尾按钮。
最后,自己基于网上的一个简单的例子重写了一个分页的小插件,效果如下。
demo页面:

最后
好久没有这样比较“原生态”的写前端了,哈哈哈,写写小工具小插件,还是觉得挺好玩的,这篇文章只是记录了:
- 页面渲染使用的是
art-template
模版引擎 - 简单封装了一个分页小插件的
KPagination.js
本次开发任务的笔记待续哦,后面还会补充其他功能的一些总结。
