Javascript onSubmit函数无法调用其中的函数
我正在做一个表格。我想让它检查单选按钮，看看他们是否被点击，如果没有有一个消息给用户检查一个 我试着只输入它，然后我试着继续我的else if语句，其中有错误消息，然后我试着在onsubmit函数中创建一个函数，它根本没有启动，然后我试着在onsubmit函数之外创建一个函数，并试图调用它，但它没有启动。我甚至尝试将函数移动到onsubmit函数的上方或下方 我取消了提交，看看问题是否出在radioB功能上，但这两个功能都不会启动 我陷入了绝望。请帮忙 这是代码Javascript onSubmit函数无法调用其中的函数,javascript,html,function,onsubmit,Javascript,Html,Function,Onsubmit,我正在做一个表格。我想让它检查单选按钮，看看他们是否被点击，如果没有有一个消息给用户检查一个 我试着只输入它，然后我试着继续我的else if语句，其中有错误消息，然后我试着在onsubmit函数中创建一个函数，它根本没有启动，然后我试着在onsubmit函数之外创建一个函数，并试图调用它，但它没有启动。我甚至尝试将函数移动到onsubmit函数的上方或下方 我取消了提交，看看问题是否出在radioB功能上，但这两个功能都不会启动 我陷入了绝望。请帮忙 这是代码 <!DOCTYPE htm

它之所以不能工作，是因为您的Javascript完全错误
}
radioB();
else // <--- what does it mean?
return true;
将侦听器放在表单的提交处理程序上，而不是按钮上，因为表单可以在不单击提交按钮的情况下提交。好的，我已经完成了您的建议。我下载了Google Chrome并编辑了我的代码，直到没有错误。我仍然无法使这些函数工作。我把编辑过的代码放在我的第一篇文章中。如果你还有什么建议，请告诉我。
else if (radioButton ! = true) {
// <-- you have else if, but there is no if block and it is != not ! =
