我正在创建一个“社交媒体评论部分”(您可以通过在底部的评论框中输入内容来添加您自己的评论。)我想添加一个编辑按钮,该按钮可以更改为对于单击编辑按钮的任何评论。我非常不熟悉如何做到这一点。我尝试添加一个单击功能,该功能创建一个文本框,您可以在其中输入文本,但它会在每个具有编辑按钮的评论上创建文本框。 如何使“编辑”按钮更具体地显示所点击的评论?
$(document).ready(function(){ let value; let storeValues = [] let storeValueName; let storeValueComment; $('#addComment').click(function(){ storeValueName = getName(); storeValueComment = getComment(); storeValues.push(storeValueName); storeValues.push(storeValueComment); value = getName() + getComment(); function getName(){ let grabName; $('#name').val(function(i, v){ grabName = v; }) return grabName; } function getComment(){ let grabComment; $('#bodyText').val(function(i, v){ grabComment = v; }) return grabComment } console.log(storeValues); $('.eachComment').prepend('<div class="comments">' +'<img class="imgClass" src="userImage.jpg">'+'<p class="nameVal">' + storeValueName +'</p>' + '<p class="commentVal">'+ storeValueComment +'</p>'+ '<input type="button" id="edit" value="Edit" />'+ '<input type="button" id="delete" value="Delete" />' + '</div>'); $('#edit').click(function(){ }) }) })

从一般意义上回答你的问题......
当您添加事件侦听器时,特定元素将显示在事件的 target
属性上。所以,如果我们有这样的东西:
我们实际上可以向 div 添加一个 click
处理程序,因为 事件“冒泡”直到它。
document.querySelector('.posts').addEventListener('click' (e) => { console.log(e.target.textContent); // Button 1, Button 2, etc. });
