【问题描述】：
我做了一个申请，让人们填写申请表。我做了一些表单验证，但现在我想确保当用户点击提交按钮时，它会检查以确保所有字段都已填写。我被卡住了，无法弄清楚这个难题的最后一部分。
我相信完成这项工作所需要的只是一个 Application.js 如果有人可以看看这个并让我知道如果我遗漏了什么怎么办。我没有包括 CSS 表或照片。感谢您抽出宝贵时间提供帮助。
这是表格。 “应用程序.html”

看看这个stackoverflow.com/questions/7410063/…相信是你要找的。正如其他人告诉您的那样，在服务器端进行验证并记住您必须永远信任客户端
-
@Andres 这是什么类型的表格？也是一个.js？我喜欢我阅读的内容，但对它所需的表单类型（css、php、js）并不十分熟悉。

在该示例中，您将使用您的申请表（它是它的 id），它会在提交表单之前调用一个函数来验证它，但如果您出于安全目的这样做，则不是这样有效
