This article mainly introduces the implementation of dynamic and static data table paging in layui. It has a certain reference value. Now I share it with you. Friends in need can refer to it.
The development management background is every development This is a link that everyone should be familiar with. As back-end programmers, all the company’s confidential data is in our hands, so at this time, if you are not a core member of the company, you cannot access certain data. At this time, all the confidential data of the company are in our hands. All the work fell into our hands, from PS to Linux, we needed to do it ourselves. Fortunately, we discovered layui, a front-end framework, which relieved our pressure to a great extent.
Today we will first learn layui to implement dynamic data tables, static data tables, and table paging, which also involves dynamic refresh of data tables, use of data table toolbars, and form submission This static paging is also applicable to information websites. My working development environment is the debian desktop version, so all experiments are also tested on the basis of debian

and network# of chrome, firefox ##Check and carefully study and analyzeData table toolbar events
For example, to obtain form data, you only need to listen to the form submission event, and you can directly obtain all parameters and values at once: <pre class="brush:php;toolbar:false;"><script>
layui.use([&#39;form&#39;,&#39;jquery&#39;],function(){
let form = layui.form,
$ = layui.$;
form.on(&#39;submit(fuck-submit)&#39;, function(data){
if(data.field.password && data.field.password.length < 5){
layer.msg(&#39;密码不能小于５位&#39;);
return false;
}
$.post(&#39;index.php?&a=adminEdit&op=update&uid=&#39;+data.field.uid,{
username:data.field.username,
password:data.field.password,
level:data.field.level,
is_enabled:data.field.is_enabled
}, function(responseText){
//console.log(responseText);
if(responseText.errno === 8){
layer.msg(responseText.errstr,{icon:6});
return false;
} else {
layer.msg(responseText.errstr,{icon:5});
location.reload();
}
},&#39;json&#39;
);
return false;
});
});
</script></pre> Here is the official document:
form.on('submit(*)', function(data){
console.log(data.elem) //被执行事件的元素DOM对象，一般为button对象
console.log(data.form) //被执行提交的form对象，一般在存在form标签时才会返回
console.log(data.field) //当前容器的全部表单字段，名值对形式：{name: value}
return false; //阻止表单跳转。如果需要表单跳转，去掉这段即可。
}); The data table we are going to operate today also uses this method. First, let’s take a look at how to generate and render the toolbar:
You only need to insert a container in the body part. Note that the type
javascript here is text/html, this is forlayuiIt is used for analysis. The d here is the data when we render the form. The values of all fields can be obtained in this d
<table class="layui-hide" lay-filter="fucktest" id="test"></table>
<script type="text/html" id="barDemo">
<a class="layui-btn layui-btn-xs" user_id="{{d.admin_id}}" lay-event="edit">编辑</a>
</script> // 这里就是我们渲染表格字段的地方，和上面的容器进行绑定，容器里面可以通过d.fixed来获取到
{fixed: 'right', width:158,title:'操作', align:'center', toolbar: '#barDemo'} Then we can bind events to the toolbar. Here I only use the edit event table.on('tool(fucktest)', function(obj){ //注：tool是工具条事件名，test是table原始容器的属性 lay-filter="对应的值"
var data = obj.data; //获得当前行数据
var layEvent = obj.event; //获得 lay-event 对应的值（也可以是表头的 event 参数对应的值）
var tr = obj.tr; //获得当前行 tr 的DOM对象
if(layEvent === 'detail'){ //查看
//do somehing
} else if(layEvent === 'del'){ //删除
layer.confirm('真的删除行么', function(index){
obj.del(); //删除对应行（tr）的DOM结构，并更新缓存
layer.close(index);
//向服务端发送删除指令
});
} else if(layEvent === 'edit'){ //编辑
// 开始根据用户id来进行获取用户进入新窗口
var index = layer.open({
type: 2,
title:'编辑管理员',
area: ['700px', '560px'],
maxmin: true,
content: 'index.php?c=adminUser&a=editUser&uid='+data.admin_id
});
layer.full(index);
}
}) so that the corresponding event can be activated after clicking edit. Here we open a new full-screen pop-up window. Modify administrator information
After the modification is completed, if you just want to simply reload the data table, you can use the method we used earlier. If you want to refresh the page, use it directlylocation.reload()
// 重载数据表
var active = {
reload:function(){
var demoReload = $("#demoReload");
var dateReload = $("#dateReload");
table.reload('testReload',{
where:{
username:demoReload.val(),
dates:dateReload.val()
}
});
}
};
$("#fresh-btn").click(function(){active.reload();});
$("#fresh-page-btn").click(function(){location.reload();});Here is the official example toolbar-binding column toolbarThe template corresponding to toolbar, which can be stored anywhere on the page: <script type="text/html" id="barDemo">
<a class="layui-btn layui-btn-xs" lay-event="detail">查看</a>
<a class="layui-btn layui-btn-xs" lay-event="edit">编辑</a>
<a class="layui-btn layui-btn-danger layui-btn-xs" lay-event="del">删除</a>
<!-- 这里同样支持 laytpl 语法，如： -->
{{# if(d.auth > 2){ }}
<a class="layui-btn layui-btn-xs" lay-event="check">审核</a>
{{# } }}
</script>
注意：属性 lay-event="" 是模板的关键所在，值可随意定义。Rendering toolbar: table.render({
cols: [[
{field:'id', title:'ID', width:100}
,{fixed: 'right', width:150, align:'center', toolbar: '#barDemo'} //这里的toolbar值是模板元素的选择器
]]
});
等价于：
<th lay-data="{field:'id', width:100}">ID</th>
<th lay-data="{fixed: 'right', width:150, align:'center', toolbar: '#barDemo'}"></th>Toolbar binding event: //监听工具条
table.on('tool(test)', function(obj){ //注：tool是工具条事件名，test是table原始容器的属性 lay-filter="对应的值"
var data = obj.data; //获得当前行数据
var layEvent = obj.event; //获得 lay-event 对应的值（也可以是表头的 event 参数对应的值）
var tr = obj.tr; //获得当前行 tr 的DOM对象
if(layEvent === 'detail'){ //查看
//do somehing
} else if(layEvent === 'del'){ //删除
layer.confirm('真的删除行么', function(index){
obj.del(); //删除对应行（tr）的DOM结构，并更新缓存
layer.close(index);
//向服务端发送删除指令
});
} else if(layEvent === 'edit'){ //编辑
//do something
//同步更新缓存对应的值
obj.update({
username: '123'
,title: 'xxx'
});
}
});For a more detailed introduction, please read the official documentation carefully layui table moduleStatic table And paging In many cases, excessive use of dynamic rendering on the APIMixed parsing for display:and the requiredparam, so we still recommend using static tables for programs with higher security requirements, whether through template engines, or directly using back-end dynamic language mixing. Users can only see it in the end. The parsed page is also necessary for program protection. One of myhackerfriends exploits loopholes in this way when performing penetrationI directly use the static form herephp

layui.use('laypage', function(){
var laypage = layui.laypage;
laypage.render({

,count: <?php echo $log_num;?> // 数据总数，从服务端得到
,curr: <?php echo $currpage;?> // 服务器端回传当前页
,jump: function(obj, first){
//obj包含了当前分页的所有参数，比如：
console.log(obj.curr); //得到当前页，以便向服务端请求对应页的数据。
console.log(obj.limit); //得到每页显示的条数
//首次不执行,使用原始的curr,后面需要自己通过回传来更新
var curr = obj.curr;
if(!first){
location.href='index.php?&a=adminLogList&page='+obj.curr;
}
}
});
});
</script>
</body>
<?php $this->import('foot');?>The principle here is very simple , mainly using the layui, using jump to trigger events
public function adminLogList()
{ // 接收当前页，如果没有收到默认是第一页
$page = $this->request->getGet('page','intval',1);
// 设置limit查找起始，DEFAULT_PER_PAGE为全局变量，设置的是每页显示10条
$start = ($page-1)*DEFAULT_PER_PAGE;
// 获取总日志数量
$adminlog_num = adminLogs::getItemsNumber();
// 分页查找，其他查询条件暂时不传
$admin_log_list = adminLogs::getItems('','','','','',$start);
$log_list = array();
foreach($admin_log_list as $kk => $vv){
if($vv['admin_id'] > 0){
try{
$admins = admins::getItemById($vv['admin_id']);
$log_list[$kk]['username'] = $admins['username'];
} catch (exception2 $e){
logexception($e->format_stack_trace());
}
} else {
$log_list[$kk]['username'] = 'Tourists';
}
$log_list[$kk]['log_id'] = $vv['log_id'];
$log_list[$kk]['control'] = $vv['control'];
$log_list[$kk]['action'] = $vv['action'];
$log_list[$kk]['is_success'] = $vv['is_success'];
$log_list[$kk]['client_ip'] = ip2location($vv['client_ip']);
$log_list[$kk]['remark'] = $vv['remark'];
$log_list[$kk]['date'] = $vv['date'];
$log_list[$kk]['title'] = $vv['title'];
unset($admin_log_list[$kk]);
}
self::$view->setVar('currpage',$page);
self::$view->setVar('log_num',$adminlog_num);
self::$view->setVar('log_list',$log_list);
self::$view->render('default_addloglist');
}最终效果，已经完成静态分页，此部分功能也适用于信息类网站：
