我有一个注册表单，应该根据我创建的每个函数（在validation.js文件中）检查输入数据，在一切正常之后，它应该将所有数据返回到.php文件，这将保存在phpmyadmin中数据库。
然而它无效
Test1：验证工作正常（单独不包括action = .php） Test2：未经验证，数据存储在数据库中（phpmyadmin） 测试3：通过验证并使用action = .php）它无法使用验证部分
请帮帮我。

答案 0 :(得分：0)
您的验证方法似乎总是返回false。如果onSubmit调用的代码返回false，则不会执行该操作。 onclick和其他事件函数也是如此。
一旦你评估了所有条件是有效的，你应该返回true告诉表单它可以接管并做它的事情。
