Question

我已经制作了一个webform，我有一个脚本用于处理这个表单（php）这个脚本工作正常，但我也做了一个javascript错误检查器，现在当我尝试在该脚本中获取一些php时，它不知何故，错误，并没有检查我的错误，在JavaScript，

下面你会发现我为错误handeling写的代码，我还没有完成，但我现在卡住了，因为我需要去我的数据库检查一些东西，并且javascript错误处理程序错误。

快速漫步：为了测试这个错误处理，我自己有0业力。我点击提交，即使我没有填写我的用户名，它没有显示错误。并直接将我带到php处理程序，它确实发现错误。

我看不出问题是什么，或者为什么它不起作用，因为我在javascript中还不够熟练。
