模式未显示在按钮单击上 - 香草 JavaScript

Question

我正在尝试使用vanilla JS切换模式，但是显示按钮不起作用。我希望模式在单击显示按钮时添加一个类 - 位于项目框的右下角。显示类将模态显示为 100vhx100vw 框。这是我的代码：// Variableslet buttonOne = document.getElementById("project-1-button");let modalOne = document.getElementById("project-1-modal");let closeOne = document.getElementById("project-1-close");// Functionsfunction modalOneShow() {  modalOne.classList.add("show");}function modalOneRemove() {  modalOne.classList.remove("show");}// Event ListenersbuttonOne.addEventListener("onclick", modalOneShow);closeOne.addEventListener("onclick", modalOneRemove);.projects-section {  height: auto;  width: 100%;  display: flex;  align-items: center;  justify-content: center;}.projects-container {  height: 90%;  width: 90%;  display: flex;  align-items: center;  justify-content: center;  flex-direction: column;  margin: 100px 0;}.projects-heading {  height: auto;  width: 90%;  display: flex;  align-items: center;  justify-content: center;  margin: 30px 0;}.project-box {  height: 400px;  width: 800px;  display: flex;  align-items: center;  justify-content: center;  position: relative;  background-color: yellow;}.project-button {  height: 10%;  width: 40%;  display: flex;  align-items: center;  justify-content: flex-end;  position: absolute;  bottom: 5px;  right: 20px;}.project-button h4 {  border-bottom: 1px solid #000;  cursor: pointer;}.project-modal {  height: 100vh;  width: 100%;  align-items: center;  justify-content: center;  z-index: 10;  background-color: #e8ead3;  position: fixed;  top: 0;  left: 0;}.project-modal-content {  height: 90%;  width: 90%;  display: flex;  align-items: center;  justify-content: center;  flex-direction: column;  position: relative;}.project-close {  height: 40px;  width: 40px;  position: absolute;  top: 0;  right: 10px;  cursor: pointer;}#project-1-modal {  display: none;}如果有人能为我指出我做错了什么的正确方向，那就太好了。谢谢！

Answer 1

您已添加而不是 ：onclickclick

target.addEventListener(type, listener [, options]);

有关参考文档types

应按照您的情况进行更正：

buttonOne.addEventListener("click", modalOneShow);

Answer 2

尝试更改单击以单击事件列表。

buttonOne.addEventListener("click", modalOneShow);
closeOne.addEventListener("click", modalOneRemove);

Answer 3

原因已知（“点击”应为“点击”）。只是为了好玩：使用事件委派和classList.toggle

document.addEventListener("click", toggleModal);

function toggleModal(evt) {

  const originBttn = evt.target.closest("#project-1-button");

  const originModalOpen = evt.target.closest("#project-1-modal");

  

  if (!originBttn && !originModalOpen) { return; }

  

  const modalNode = document.querySelector("#project-1-modal");

  modalNode.classList.toggle("show"); 

}
