Javascript：刪除父元素

Question

如何使用事件偵聽器刪除子元素的父元素。

我有一個 html 表單，提交時運行 makeNewBook function 並將包含表單信息的 object 推送到名為 myLibrary 的數組。 然后它創建一個容器 div，顯示來自該表單的信息，該表單放置在一個名為shelf(bookshelf) 的預定義div 中。 該容器中還有一個刪除按鈕。

刪除按鈕有一個事件偵聽器，可以從數組中刪除 object，但是我怎樣才能使用最后一個事件偵聽器從頁面中刪除容器？ 謝謝

Java腳本：

function makeNewBook() {
    let x = new Book(bookInput.value, authorInput.value, pagesInput.value, readInput.value)   //create a new book using the input vals
    myLibrary.push(x)                                                                         //push the new book object to the books array;
    console.table(myLibrary)


    let container = document.createElement('div')    //create a container for all the info
    container.setAttribute('class', 'container')

    let titlePara = document.createElement('p')
    titlePara.textContent += 'Title: ' + x.title;
    let authorPara = document.createElement('p')
    authorPara.textContent += 'Author: ' + x.author;
    let pagesPara = document.createElement('p')
    pagesPara.textContent += 'Pages: ' + x.pages;
    let readPara = document.createElement('p')
    readPara.textContent += 'Read: ' + x.read


    // delete button
    let deleteBtn = document.createElement('input');
    deleteBtn.setAttribute('class','delete')
    deleteBtn.type = 'submit';
    deleteBtn.value = 'Delete'



    // append everyhting to the container div to be put on the shelf
    container.appendChild(titlePara)
    container.appendChild(authorPara)
    container.appendChild(pagesPara)
    container.appendChild(readPara)
    container.appendChild(deleteBtn)
    container.setAttribute('class', `container ${x.title}`)
    shelf.append(container)




    deleteBtn.addEventListener('click',()=>{
        let index= myLibrary.indexOf(x); 
        myLibrary.splice(index,1);       //delete that object from the myLibrary array

        document.body.remove(deleteBtn.parentElement)    //This does not work
    })

}

您必須在節點本身上調用remove

deleteBtn.parentElement.remove();
