layui中form表单提交数据的方式

<form class="layui-form">
  <div class="layui-form-item">
    <input type="text" id="subTitle" name="subTitle" lay-verify="required" class="layui-input">
  </div>
  <div class="layui-form-item">
    <button class="layui-btn" lay-submit lay-filter="formDemo">添加</button>
  </div>
</form>

form标签上添加上 class="layui-form" 属性

button按钮添加上 lay-filter = "formDemo" 属性

form.on('submit(formDemo)', function (data) {
              layer.msg(JSON.stringify(data.field));
 
              //JSON.stringify(data.field)   这是表单中所有的数据
              
              var articleFrom = data.field.articleFrom;
 
              var articleSummary = data.field.articleSummary;
})
