我有一个活动日历。我遇到的问题是，每次将事件插入特定日期时，我的其他事件innerHTML也会更改。
我尝试过event.stopPropagation（）以及event.stopImmediatePropagation（）。
这似乎不起作用。
关于如何进行这项工作的任何建议？
提前谢谢！
let dates = document.querySelectorAll(".calendar-date button.date-item");
dates.forEach(function(date){
date.addEventListener("click",function(e){
let parentNode = e.currentTarget.parentNode;
let events = parentNode.querySelector(".calendar-events");
document.querySelector("#add-modal").classList.add("active");
let form = document.querySelector("#add-event").addEventListener("submit",function(formEvent){
formEvent.preventDefault();
document.querySelector("#add-modal").classList.remove("active");
let inputValue = this.querySelector("input[name='event-input']");
events.innerHTML = '<a class="calendar-event bg-success text-light" href="#calendars">'+inputValue.value+'</a>';
});
e.stopPropagation();
});

每次单击日期时，都会向“提交”操作中添加一个侦听器，以更改其内部html，因此您的日期最终将永远是该“提交”操作的监听。
一种解决此问题的快速方法是在完成innerHtml的编辑后将其删除，或将其设置为仅使用{once: true}触发一次。
let dates = document.querySelectorAll(".calendar-date button.date-item");
dates.forEach(function(date){
date.addEventListener("click",function(e){
let parentNode = e.currentTarget.parentNode;
let events = parentNode.querySelector(".calendar-events");
document.querySelector("#add-modal").classList.add("active");
let form = document.querySelector("#add-event").addEventListener("submit",function(formEvent){
formEvent.preventDefault();
document.querySelector("#add-modal").classList.remove("active");
let inputValue = this.querySelector("input[name='event-input']");
events.innerHTML = '<a class="calendar-event bg-success text-light" href="#calendars">'+inputValue.value+'</a>';
}, {once: true});
e.stopPropagation();
});
