自定义模式对话框

虽然 htmx 非常适合使用 CSS 框架（如 Bootstrap 和 UIKit ）内置的对话框，但 htmx 还可以轻松从头开始构建模式对话框。下面是构建模式对话框的一种方法的简单示例。

高级用法

我们将创建一个按钮，用于从服务器加载远程内容，然后在模态对话框中显示它。模态内容将添加到 <body> 元素末尾名为 #modal 的 div 中。

在这个演示中，我们将在 CSS 中定义一些漂亮的动画，然后在用户完成后使用一些Hyperscript 从 DOM 中删除模式。Hyperscript 不是 htmx 的必需项，但两者设计为一起使用，并且它比 JavaScript 更适合编写异步和面向事件的代码，这就是我们为这个示例选择它的原因。

主页 HTML

<button class="btn primary" hx-get="/modal" hx-target="body" hx-swap="beforeend">Open a Modal</button>

模态 HTML 片段

<div id="modal" _="on closeModal add .closing then wait for animationend then remove me">
    <div class="modal-underlay" _="on click trigger closeModal"></div>
    <div class="modal-content">
        <h1>Modal Dialog</h1>
        This is the modal content.
        You can put anything here, like text, or a form, or an image.
        <br>
        <br>
        <button class="btn danger" _="on click trigger closeModal">Close</button>
    </div>
</div>

自定义样式表

/***** MODAL DIALOG ****/
#modal {
    /* Underlay covers entire screen. */
    position: fixed;
    top:0px;
    bottom: 0px;
    left:0px;
    right:0px;
    background-color:rgba(0,0,0,0.5);
    z-index:1000;

    /* Flexbox centers the .modal-content vertically and horizontally */
    display:flex;
    flex-direction:column;
    align-items:center;

    /* Animate when opening */
    animation-name: fadeIn;
    animation-duration:150ms;
    animation-timing-function: ease;
}

#modal > .modal-underlay {
    /* underlay takes up the entire viewport. This is only
    required if you want to click to dismiss the popup */
    position: absolute;
    z-index: -1;
    top:0px;
    bottom:0px;
    left: 0px;
    right: 0px;
}

#modal > .modal-content {
    /* Position visible dialog near the top of the window */
    margin-top:10vh;

    /* Sizing for visible dialog */
    width:80%;
    max-width:600px;

    /* Display properties for visible dialog*/
    border:solid 1px #999;
    border-radius:8px;
    box-shadow: 0px 0px 20px 0px rgba(0,0,0,0.3);
    background-color:white;
    padding:20px;

    /* Animate when opening */
    animation-name:zoomIn;
    animation-duration:150ms;
    animation-timing-function: ease;
}

#modal.closing {
    /* Animate when closing */
    animation-name: fadeOut;
    animation-duration:150ms;
    animation-timing-function: ease;
}

#modal.closing > .modal-content {
    /* Animate when closing */
    animation-name: zoomOut;
    animation-duration:150ms;
    animation-timing-function: ease;
}

@keyframes fadeIn {
    0% {opacity: 0;}
    100% {opacity: 1;}
}

@keyframes fadeOut {
    0% {opacity: 1;}
    100% {opacity: 0;}
}

@keyframes zoomIn {
    0% {transform: scale(0.9);}
    100% {transform: scale(1);}
}

@keyframes zoomOut {
    0% {transform: scale(1);}
    100% {transform: scale(0.9);}
}
