Introduction:
The development of aviation service platforms has become a major trend in modern society. One of the indispensable and important platforms. Users need to conduct ticket enquiry, booking and payment through the aviation service platform. This article will give you specific steps and code examples to teach you how to use the Layui framework to develop an aviation service platform that supports instant query and booking of air tickets.

Preparation:
Before starting development, you need to ensure that the Layui framework has been installed. First, download the Layui compressed package and unzip it. Then, include Layui’s CSS and JS files in your HTML file. The following is a sample code:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8">
    <title>航空服务平台</title>
    <link rel="stylesheet" href="layui/css/layui.css">
</head>
<body>
    <!-- 页面内容 -->
    <script src="layui/layui.js"></script>
</body>
</html>

Build a query page:
Add an input box and a query button to your HTML file. Users can enter flight information and click the button to query. . The following is a sample code:

<div class="layui-form-item">
    <input type="text" name="flight" placeholder="请输入航班号" autocomplete="off" class="layui-input">
</div>
<div class="layui-form-item">
    <button class="layui-btn" lay-filter="search" lay-submit>查询</button>
</div>

Write query code:
Use Layui's form module to process the form, and request the back-end interface through ajax to query flight information. The following is a sample code:

<script>
layui.use(['form', 'jquery'], function(){
    var form = layui.form;
    var $ = layui.jquery;
    
    form.on('submit(search)', function(data){
        var flight = data.field.flight;
        
        // 发起ajax请求查询航班信息
        $.ajax({
            url: '/api/search_flight',
            type: 'POST',
            data: {flight: flight},
            success: function(res){
                // 处理查询结果
                if (res.code === 0) {
                    layer.msg('查询成功');
                    // 显示查询结果
                    // ...
                } else {
                    layer.msg('查询失败');
                }
            },
            error: function(){
                layer.msg('网络错误');
            }
        });
        
        return false;
    });
});
</script>

Display query results:
Use Layui's table module to display the queried flight information. The following is a sample code:

<table class="layui-table" id="flightTable"></table>

<script>
layui.use(['table', 'jquery'], function(){
    var table = layui.table;
    var $ = layui.jquery;
    
    // 渲染表格
    table.render({
        elem: '#flightTable',
        height: 500,
        url: '/api/get_flight_list',
        method: 'POST',
        cols: [[
            {field: 'flightNo', title: '航班号'},
            {field: 'departure', title: '出发地'},
            {field: 'destination', title: '目的地'},
            {field: 'departureTime', title: '出发时间'},
            {field: 'arrivalTime', title: '到达时间'},
            {title: '操作', toolbar: '#flightToolbar'}
        ]]
    });
    
    // 监听表格工具栏按钮点击事件
    table.on('tool(flightTable)', function(obj){
        var data = obj.data;
        if(obj.event === 'book'){
            // 跳转到预订页面
            window.location.href = '/booking?flight=' + data.flightNo;
        }
    });
});
</script>

Implementing the booking function:
After jumping to the booking page, the user can fill in personal information and click the booking button to complete the ticket booking. The following is the sample code:

<form class="layui-form" action="">
    <div class="layui-form-item">
        <label class="layui-form-label">航班号</label>
        <div class="layui-input-block">
            <input type="text" name="flight" value="{{flight}}" readonly class="layui-input">
        </div>
    </div>
    <div class="layui-form-item">
        <label class="layui-form-label">姓名</label>
        <div class="layui-input-block">
            <input type="text" name="name" placeholder="请输入姓名" class="layui-input">
        </div>
    </div>
    <div class="layui-form-item">
        <button class="layui-btn" lay-submit lay-filter="book">预订</button>
    </div>
</form>

<script>
layui.use(['form', 'jquery'], function(){
    var form = layui.form;
    var $ = layui.jquery;
    
    form.on('submit(book)', function(data){
        var flight = data.field.flight;
        var name = data.field.name;
        
        // 发起ajax请求进行机票预订
        $.ajax({
            url: '/api/book_flight',
            type: 'POST',
            data: {flight: flight, name: name},
            success: function(res){
                if (res.code === 0) {
                    layer.msg('预订成功');
                    // 跳转至支付页面
                    window.location.href = '/payment?order=' + res.orderId;
                } else {
                    layer.msg('预订失败');
                }
            },
            error: function(){
                layer.msg('网络错误');
            }
        });
        
        return false;
    });
});
</script>
