我正在尝试在node.js中使用fullcalendar，其中开始和结束时间的参数是从带有JSON.parse的字符串中提取的
我已经尝试过将对象数组（代表事件的开始和结束时间）手动输入到events函数中，并且效果很好。
这是我当前的代码：
<!DOCTYPE html>
<html lang="en">
<head>
<title>Title</title>
<script async src="https://www.googletagmanager.com/gtag/js?id=UA-74664112-6"></script>
<script>
window.dataLayer = window.dataLayer || [];
function gtag() {
dataLayer.push(arguments);
}
gtag('js', new Date());
gtag('config', 'UA-74664112-6');
</script>

如果运行正确，则事件应显示在日历上，而没有任何错误-但是，当我运行代码时，错误消息显示“无法读取未定义的Type的属性'hasTime'：无法读取未定义的属性'hasTime'”发生。这是确切的错误：

答案 0 :(得分：0)
大多数情况下，此 hastime 错误会在您的事件属性的开始或结束日期没有值或其中包含空值时显示
