我有一个似乎无法解决的问题。我正在创建一个个性测试,当我提交表单时,它会暂时在“答案”框中显示代码,但随后会快速刷新页面并清除所有数据。我想知道问题是否出在我的javascript函数“ tabulateanswers”上,但我看不到是什么原因引起的。我以前在javascript中添加了一个弹出框,以尝试强制停止刷新,我可以看到结果是否正在显示,但是经过一些调整后,我再也无法显示该框。如果有人可以看一下我的JavaScript并指出正确的方向/告诉我我在哪里出错?抱歉,如果无法回答,我找不到它。

答案 0 :(得分:0)
如果您在提交时调用了tabulateAnswers
,则可以在其结尾处return false;
并阻止这种行为
由于您使用的是onclick,因此您还希望prevent the default这样的操作不会发生:
function tabulateAnswers(_event) {
...
_event.preventDefault();
return false;
}
另一种选择是使用button
输入类型,而不触发表单提交。

只需使用jQuery:
<form id="form">
<input type="submit" value="Submit" />
</form>
<script>
$("#form").submit(e => {
e.preventDefault();
// Handle form
});
</script>
