php - 菜鸟: display err_msg on page (pt. 2)

标签 php javascript jquery error-handling validation

我昨天发布了此邮件，如果您对此做出了回应，并再次看到此邮件感到沮丧，我深表歉意!但是该表格现在根本无法使用，并且希望能为解决该问题提供帮助。

我有一个将数据发送到数据库并需要验证的表单。昨天至少可以正确验证，但是今天我什至无法正确连接到我的操作页面。这是两个页面:

带表格的页面:

最佳答案

我承认我没有彻底阅读您的代码，但是以下任何一个都可能是您的问题:

  • 在调用脚本中的MM_validateForm()时，我认为您需要传递HTML表单字段的名称，但是尽管每个参数似乎都是正确的，但第一个是“名称”，它似乎不是有效的表单字段。
  • addValidation()中的MM_validateForm()函数是什么，它有什么作用？由于我看不到它的定义，因此我认为它可能在您的JS中产生错误。
  • 在MM_validateForm()中，在行号之后。 3＆4，似乎变量errors永远不会为空，从而阻止您提交表单？

    • 我不清楚您停留在哪一点-您的表格根本没有提交吗？您是否尝试在errors的末尾发出MM_validateForm()变量的警报。也许有帮助。
