javascript - NodeList 事件不起作用

我有一个事件日历。我遇到的问题是每次将事件插入到特定日期时,我的其他事件 innerHTML 也会发生变化。

我已经尝试过 event.stopPropagation() 以及 event.stopImmediatePropagation()。

这似乎行不通。

关于我如何使这项工作有什么建议吗?

提前致谢!

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();
});
});

最佳答案

每次您点击一个日期时,您都会向更改其内部 html 的“提交”操作添加一个监听器,因此您的日期最终会永远监听此“提交”操作。

解决此问题的一种快速方法是在编辑完 innerHtml 后删除监听器,或者使用 {once: true} 将其设置为仅触发一次。

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();
});
});
