Question

好的，我对javascript不太满意，只是开始学习它。我所有的形式都可以使用，但是我想做的是，如果某人在1分钟内未回答此测验中的任何问题，它将提交未回答的值。让我们将该值称为“ e”。因此，在我的输入中，我具有值a，b，c，d，如果他们在一分钟内未回答，我希望它提交值“ e”。现在，表单已提交，但是我尝试了多种方法来尝试使其带有值，但是它不起作用

任何帮助将不胜感激。谢谢。

Answer 1

您可以添加
<input type="radio" name="answerv" value="e" style="display:none" checked>
在您的表单中无处不在。

经过一定时间后提交带有默认值的表单吗？
