layui实现动态和静态分页
开发管理后台是每一个开发人员都要熟悉的一个环节，作为后端程序员，公司的所有机密数据都掌握在我们手上，所以这个时候，如果不是公司的核心成员，是不能接触到某些数据的，这个时候所有的工作都落到了我们的手上，从PS到Linux都需要我们亲历亲为，还好发现了layui这个前端框架，很大程度上减轻了我们的压力．
今天我们先来学习一下layui实现动态数据表，静态数据表，以及表格的分页，其中还涉及到动态刷新数据表,数据表工具栏使用,表单提交等功能，这个静态分页同样适用在信息类网站,我的工作开发环境是debian桌面版，所以所有的实验也是在debian基础上测试

实现过程
业务逻辑我都写到注释里面了，这样大家也友好一些，避免一会看代码，一会看说明容易分神

表格模块：http://www.layui.com/doc/modules/table.html
调试的时候可以打开chrome,firefox 的 console 和 network进行查看，仔细研究分析
数据表工具条事件
工具栏是指在行单元格内可以操作对应的行，因为使用layui的元素监听，很容易就获取到相应对应整行的数据.
比如获取表单的数据,只需要监听表单提交事件，直接就可以一次获取到所有的参数和值：
<script>
layui.use(['form','jquery'],function(){
let form = layui.form,
$ = layui.$;
form.on('submit(fuck-submit)', function(data){
if(data.field.password && data.field.password.length < 5){
layer.msg('密码不能小于５位');
return false;
}
$.post('index.php?&a=adminEdit&op=update&uid='+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();
}
},'json'
);
return false;
});
});
</script>
这里是官方文档的：
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。
});
我们今天要操作的数据表也是要采用这种方式，首先我们看看看怎样生成和渲染出工具条：
只需要在body部分插入一个容器,注意这里的javascript的type是text/html,这个是供layui解析用的，在这里的d也就是我们在渲染表格的时候的数据,所有的字段的值都可以在这个d里面获取到
<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>
