jQuery 到 Javascript 用于引导模式

Question

我曾经在 jQuery 中编写了一行代码来打开引导模式$("#Modal").modal("show"); . 现在我正在尝试准备使用纯 JS，以便我的应用程序不再需要加载 jQuery。

不知何故，我能够打开 model 但关闭按钮和模式外的点击事件不起作用。

var div = document.getElementById("TestModel");
div.innerHTML += "<%= j render 'modal' %>";
div.classList.add("show");
div.style.display = "block";
document.body.innerHTML += "<div class='modal-backdrop fade show'></div>";
document.body.classList.add("mode-open");

请给我一个最好的选择。

嘿，这也应该对你有用。 它不使用 JQuery 或 Bootstrap

HTML：

<a id="gdx-lighbox-modal-unique-1" data-hover="true" type="button" class="gdx-lightbox-tooltip-open-modal lightbox-link gdx-lightbox-button" data-open="gdx-lighbox-modal-1">
Click Here
</a>

<div class="gdx-modal" id="gdx-lighbox-modal-1" data-animation="slideInOutLeft">
<div class="gdx-modal-dialog">
<header class="gdx-modal-header">   
<a class="gdx-close-modal" aria-label="close modal" data-close="">✕</a>  
</header>  
<section class="gdx-modal-content">
//Form would go here instead of the image (image just an example)
<img src="https://gdxdesigns.com/wp-content/uploads/2020/11/little-frog.jpg">  </section> 
<footer class="gdx-modal-footer"> <h3 class="gdx-modal-image-title"></h3></footer>

在反应中，以下代码在某种程度上起作用。

<div
  class={"modal fade " + (isShow ? "show" : "")}
  id="exampleModal"
  tabindex="-1"
  role="dialog"
  style={isShow ? { display: "block" } : null}
>
  <div class="modal-dialog">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Confirmation!</h5>
        <button type="button" class="close" onClick={handleNo}>
          <span aria-hidden="true">&times;</span>
        </button>
      </div>
      <div class="modal-body">{message}</div>
      <div class="modal-footer">
        <button type="button" class="btn btn-secondary" onClick={handleNo}>
          NO
        </button>
        <button type="button" class="btn btn-primary" onClick={handleYes}>
          Yes
        </button>
      </div>
    </div>
  </div>
</div>

当“isShow”为真时显示模态。
