Question

我有一个用于验证用户输入的自定义方法，但是我的表单似乎没有提交。另外，URL在我第一次提交后就会更改，并且jquery仅在URL更改后才运行。

此代码的目的是检查提交的信息是否在数据库中。该函数运行，但是名称字段的值似乎在提交时未存储，因此我不断收到名称错误。

这是我的代码：

Answer 1

您在val之后没有（）的名字，就像在其他变量上一样。

将var userName = $('#text').val;更改为var userName = $('#text').val();

这将解决您的姓名问题。

还注意到，您在#的jquery选择器中没有selection。

将var selection = $("list").val();更改为var selection = $("#list").val();

jQuery表单提交不存储值？
