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. });
