Quickly get started with the front-end framework layui
layui (homophone: UI-like) is a front-end UI framework written using its own module specifications. It follows the writing and organizational form of native HTML/CSS/JS. The threshold is extremely low and can be used out of the box.
1. Introduction
Before using layui, we must first understand layui What is it?
I think it can be summarized in one sentence of the author Xianxin: a front-end framework designed for back-end programmers.
A more detailed description is: This is a front-end framework that encapsulates various css, js, Ajax, etc. Its degree of encapsulation is so high that sometimes it is not even friendly to programmers. But for people with average front-end technology, layui is a good tool.
2. Start using layui
How to use: After downloading, import the project and then quote it
<script th:src="@{/jquery-3.3.1.min.js}"></script>
<script th:src="@{/layui/layui.js}"></script>
<link rel="stylesheet" th:href="@{/layui/css/layui.css}" />First reference jquery, then reference layui.js and layui.css.
Why does it have to be local? No CDN?
As mentioned above, layui is too encapsulated "good" and the programmer's autonomy is limited. At this time, the source code of layui needs to be modified, such as the style of css - this is also the case with layui. Correct usage, not just simple use.
layui modules: layui is modular, including form, layer, laydate, laypage and other modules. It is these modules that make up the complete layui. When using layui, you need to specify the module you are using.
Start using layui:
<script>
layui.use(['mod1', 'mod2'],function(args){
var mo1 = layui.mod1
,mo2 = layui.mod2;
});
</script>3. Layui form
The following is a demonstration of the most common form form in HTML The use of layui.
html part:
<fieldset class="layui-elem-field layui-field-title" style="margin-top:30px;">
<legend style="text-align:center;">注册新账户</legend>
</fieldset>
<form id="reform" class="layui-form layui-form-pane" th:action="@{/user/register.html}" method="POST">
<div class="layui-form-item">
<label class="layui-form-label">邮箱</label>
<div class="layui-input-block">
<input type="text" name="email" lay-verify="email" placeholder="请输入" autocomplete="off" class="layui-input" />
</div>
</div>
<div class="layui-form-item">
<label class="layui-form-label">用户名</label>
<div class="layui-input-block">
<input type="text" name="name" lay-verify="required" placeholder="请输入" autocomplete="off" class="layui-input" />
</div>
</div>
<div class="layui-form-item">
<label class="layui-form-label">密码</label>
<div class="layui-input-block">
<input type="password" name="password" lay-verify="pass" placeholder="请输入密码" autocomplete="off" class="layui-input" />
</div>
</div>
<div class="layui-form-item">
<label class="layui-form-label">重复密码</label>
<div class="layui-input-block">
<input type="password" name="repassword" lay-verify="repass" placeholder="请输入密码" autocomplete="off" class="layui-input" />
</div>
</div>
<div class="layui-form-item">
<button class="layui-btn layui-btn-fluid" lay-submit="" lay-filter="demo1">注册</button>
</div>
<div style="text-align:center;margin-top:15px;">
<input type="checkbox" name="agree" lay-skin="primary" checked=""/>
我已阅读并同意
<a href="#" id="agreementLink">《隐私条款》</a>
</div>
</form>javscript part:
<!-- js for form input and submit -->
<script>
layui.use(['form'], function(){
var form = layui.form;
//自定义验证规则
form.verify({
pass: [/(.+){6,12}$/, '密码必须6到12位']
,repass:function(value){
var pvalue = $("input[name='password']").val();
if(pvalue!=value){
return "两次输入的密码不一致";
}
}
});
//监听提交
form.on('submit(demo1)', function(data){
var agreeChecked = data.field.agree;
if(agreeChecked!="on"){
msg("未同意隐私条款");
return false;//阻止表单提交
}
});
});
</script>Rendering:
## 4. Layui pop-up layer
Let’s talk about the pop-up layer. Pop-up can be said to be a very common thing, but basic HTML/JS only has the ugly alert("") method. layui contains a pop-up layer module called layer.Two ways to use layer:
1. Just like using the form module above, declare layui.use, and then use it in the function after use ;2. Import the independent layer module file, and then use it directly;The first method will not be discussed, and the second method will be introduced here. First, download the layer file from the layer official website, unzip it and put it into your own project, then

What is the difference between layui and vue?
Apr 04, 2024 am 03:54 AM
The difference between layui and Vue is mainly reflected in functions and concerns. Layui focuses on rapid development of UI elements and provides prefabricated components to simplify page construction; Vue is a full-stack framework that focuses on data binding, component development and state management, and is more suitable for building complex applications. Layui is easy to learn and suitable for quickly building pages; Vue has a steep learning curve but helps build scalable and easy-to-maintain applications. Depending on the project needs and developer skill level, the appropriate framework can be selected.
How layui implements self-adaptation
Apr 26, 2024 am 03:00 AM
Adaptive layout can be achieved by using the responsive layout function of the layui framework. The steps include: referencing the layui framework. Define an adaptive layout container and set the layui-container class. Use responsive breakpoints (xs/sm/md/lg) to hide elements under specific breakpoints. Specify element width using the grid system (layui-col-). Create spacing via offset (layui-offset-). Use responsive utilities (layui-invisible/show/block/inline) to control the visibility of elements and how they appear.
How to transfer data in layui
Apr 26, 2024 am 03:39 AM
The method of using layui to transmit data is as follows: Use Ajax: Create the request object, set the request parameters (URL, method, data), and process the response. Use built-in methods: Simplify data transfer using built-in methods such as $.post, $.get, $.postJSON, or $.getJSON.
