我正在創建一個「社交媒體評論部分」(您可以透過在底部的評論框中輸入內容來添加您自己的評論。)我想添加一個編輯按鈕,該按鈕可以更改為對於單擊編輯按鈕的任何評論。我非常不熟悉如何做到這一點。我嘗試添加一個單擊功能,該功能創建一個文本框,您可以在其中輸入文本,但它會在每個具有編輯按鈕的評論上創建文本框。 如何讓「編輯」按鈕更具體地顯示所點擊的評論?
$(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(){ }) }) })

從一般意義上回答你的問題...
當您新增事件偵聽器時,特定元素將顯示在事件的 target
屬性上。所以,如果我們有這樣的東西:
我們實際上可以為 div 添加一個 click
處理程序,因為 事件「冒泡」直到它。
document.querySelector('.posts').addEventListener('click' (e) => { console.log(e.target.textContent); // Button 1, Button 2, etc. });
