layui form 拦截提交事件

Posted 2023-05-01

参考技术A 不需要表单自己提交，而是拦截表单提交事件后，通过ajax提交。
出现问题是：拦截提交事件失败。
原因：
1、form组件未引入
2、<form></form>上未添加 lay-filter="*****"
3、<button class="layui-btn" type="submit">立即提交</button> 上未添加lay-filter="***"
4、<button class="layui-btn" type="submit">立即提交</button>上未添加lay-submit="" （注意，引号里面的值可以不填）
