Lauiui でフロントエンドとバックエンドのインタラクションを実装する方法

<code class="javascript">layui.use(['jquery'], function($){
  $.ajax({
    url: '/api/get_data',
    success: function(data) {
      console.log(data);
    }
  });
});</code>

<code class="javascript">layui.use(['request'], function(request){
  request.post('/api/save_data', {name: 'layui'})
    .then(function(data){
      console.log(data);
    });
});</code>

<code class="html"><form id="myForm">
  <label>姓名：</label>
  <input name="name">
</form>

<script>
layui.use(['form', 'jquery'], function($, form){
  form.on('submit(submitForm)', function(data){
    $.post('/api/save_user', data.field, function(data){
      console.log(data);
    });
  });
});
</script></code>

<code class="html"><div class="layui-upload">
  <button type="button" class="layui-btn" id="uploadBtn">上传图片</button>
  <input type="file" name="file" accept="image/*" multiple hidden>
</div>

<script>
layui.use(['upload'], function(upload){
  upload.render({
    elem: '#uploadBtn',
    url: '/api/upload_image',
    done: function(res){
      console.log(res);
    }
  });
});
</script></code>
