Question

我创建了一个表单来在数据库中添加记录，因此插入记录和所有记录都运行良好。

我想对表单进行验证，现在发生了什么，虽然我已根据需要设置了字段，然后在单击提交按钮后表单正在提交，空白值正在插入数据库。

我已将此链接用于验证：

但不知何故它不适合我。

请帮助，谢谢..

Answer 1

需要参考jquery validate

  <script src="https://cdn.jsdelivr.net/jquery.validation/1.16.0/jquery.validate.min.js"></script>

然后需要初始化插件，演示示例 -

  $('#postForm').validate({
    submitHandler: function (form) { // for demo
        userAction('add');
    }
});

删除您正在提交的onclick，需要从submitHandler调用userAction

Answer 2

提交按钮的类型应该是“提交”。希望这会有所帮助。

表单未获得验证
