How to use the Layui framework to develop a travel application that supports instant navigation and location sharing

In recent years, travel applications have become an indispensable part of our daily lives. Whether traveling or dining at a nearby restaurant, people rely on navigation to help them find their destination. Additionally, an emerging trend is location sharing to facilitate our communication with others and make it easier to find our location. In order to meet these needs, this article will introduce readers to how to use the Layui framework to develop a travel application that supports real-time navigation and location sharing.

First, we need to introduce the Layui framework into our project. It can be introduced in the following way:

<link rel="stylesheet" href="https://cdn.staticfile.org/layui/2.6.8/css/layui.css">
<script src="https://cdn.staticfile.org/layui/2.6.8/layui.js"></script>

Then, we need to create a basic HTML structure to host our travel application. In the tag of HTML, add the following code:

<div class="layui-layout layui-layout-admin">
  <div class="layui-header">
    <!-- 导航栏内容 -->
  </div>
  <div class="layui-side">
    <!-- 侧边栏内容 -->
  </div>
  <div class="layui-body">
    <!-- 主要内容 -->
  </div>
</div>

Next, we need to use the components provided by Layui to implement navigation and location sharing functions. First, we need to add a search box and a button to the navigation bar to trigger the location sharing function. In the <div class="layui-header"> tag in the navigation bar, add the following code: <pre class='brush:html;toolbar:false;'>&lt;div class=&quot;layui-container&quot;&gt; &lt;div class=&quot;layui-row&quot;&gt; &lt;div class=&quot;layui-col-md3&quot;&gt; &lt;!-- 搜索框 --&gt; &lt;input type=&quot;text&quot; id=&quot;searchInput&quot; placeholder=&quot;搜索目的地&quot; class=&quot;layui-input&quot;&gt; &lt;/div&gt; &lt;div class=&quot;layui-col-md1&quot;&gt; &lt;!-- 分享按钮 --&gt; &lt;button class=&quot;layui-btn&quot; id=&quot;shareButton&quot;&gt;分享位置&lt;/button&gt; &lt;/div&gt; &lt;/div&gt; &lt;/div&gt;</pre><p>Then, we need to add a map to the sidebar, Used to display navigation and location sharing results. In the <code><div class="layui-side"> tag in the sidebar, add the following code: <pre class='brush:html;toolbar:false;'>&lt;div class=&quot;layui-side-scroll&quot;&gt; &lt;!-- 地图 --&gt; &lt;div id=&quot;map&quot;&gt;&lt;/div&gt; &lt;/div&gt;</pre><p>Next, we need to use Layui's JavaScript module to implement Navigation and location sharing features. In the <code><script></script> tag of HTML, add the following code:

layui.use(['layer', 'form'], function(){
  var layer = layui.layer;
  var form = layui.form;

  // 监听分享按钮的点击事件，并获取当前位置
  $('#shareButton').on('click', function(){
    getLocation();
  });

  // 获取当前位置的函数
  function getLocation() {
    if (navigator.geolocation) {
      navigator.geolocation.getCurrentPosition(showPosition);
    } else { 
      layer.msg("您的浏览器不支持地理定位。");
    }
  }

  // 展示位置的函数
  function showPosition(position) {
    var lat = position.coords.latitude;
    var lng = position.coords.longitude;
    var map = new BMap.Map('map');
    var point = new BMap.Point(lng, lat);
    map.centerAndZoom(point, 15);
    map.enableScrollWheelZoom(true);
    var marker = new BMap.Marker(point);
    map.addOverlay(marker);
  }
});

In the above code, we used Layui’s layer and formModule performs related operations. Among them, the layer module is used to display prompt information, and the form module is used to monitor the operation of form elements. In the getLocation() function, we use HTML5’s navigator.geolocation object to get the user’s current location, and use Baidu Map in the showPosition() function API displays location.

Finally, we need to introduce Baidu Map API to display the location on the map. In the tag of HTML, add the following code:

<script src="https://api.map.baidu.com/api?v=3.0&ak=yourAk"></script>

You need to replace yourAk in the above code with your own Baidu Map API key .

Through the above steps, we can use the Layui framework to develop a travel application that supports real-time navigation and location sharing. Users can enter their destination in the search box and share their location by clicking the share button. Through the map display, users can see the navigation route between their location and destination.

It should be noted that this article is just an example, and other functions and logic processing may be required in actual development. However, by using the Layui framework and Baidu Map API, we can easily implement a basic travel application.

I hope this article can help readers understand how to use the Layui framework to develop a travel application that supports instant navigation and location sharing, and provides some specific code examples. For more details and functions, it is recommended to consult the official documentation of Layui and Baidu Map API. Happy development!
