layui.use(['jquery'], function($){ $.ajax({ url: '/api/get_data', success: function(data) { console.log(data); } }); });
2. Using custom requests
layui also allows sending through custom request objects Request:
layui.use(['request'], function(request){ request.post('/api/save_data', {name: 'layui'}) .then(function(data){ console.log(data); }); });
3. Use the Form control
layui provides the Form control, which can easily handle form submission and data validation:
<form id="myForm"> <label>姓名:</label> <input name="name"> </form> <script> layui.use(['form', 'jquery'], function($, form){ form.on('submit(submitForm)', function(data){ $.post('/api/save_user', data.field, function(data){ console.log(data); }); }); }); </script>
4. Use the Upload control
layui provides the Upload control to easily upload files:
<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>
