NodeList事件不起作用
NodeList事件不起作用
提问于 2018-08-13 19:07:55
我有活动日历。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()。
这似乎不管用。
有什么建议可以让我这样做吗？
提前谢谢你！
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();

每次单击某个日期时，都会向"Submit“操作添加一个侦听器，该操作将更改其内部html，因此您的日期最终将永远侦听此"submit”操作。
解决这个问题的一个快速方法是在编辑完innerHtml之后删除侦听器，或者使用{once: true}将其设置为只触发一次。
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();
});
