我需要使用 javascript 在网页上创建一个模式对话框。通常这很容易，因为我可以使用 jQueryUI 或 BlockUI 之类的东西，但这里需要注意的是我不允许使用 jQuery，并且我需要支持 IE9 怪癖模式（即没有 html5 doctype）。我在网上找不到任何与我需要的东西有关的东西。有人会有建议吗？谢谢。

用一个居中的 div 做覆盖怎么样？
您可以拥有可以隐藏的 div（使用 javascript）：
<div id="overlay">
<div>
<p>Content you want the user to see goes here.</p>
</div>
</div>
叠加层的 CSS 样式可能如下所示：
#overlay {
visibility: hidden;
position: absolute;
left: 0px;
top: 0px;
width:100%;
height:100%;
text-align:center;
z-index: 1000;
}
然后你可以使用 JavaScript 来切换 overaly div 中内容的可见性：
function overlay() {
el = document.getElementById("overlay");
el.style.visibility = (el.style.visibility == "visible") ? "hidden" : "visible";
}

我创建了一个名为tomloprodModal的库，它可以满足您的需求。它是一个简单且可配置的 javascript 库，用于创建响应式和极简主义的模态窗口，没有依赖关系。
我希望它对你有帮助。
安装：
只需下载tomloprodModel.css和tomloprodModel.js并将其添加到您的网站。
您也可以使用bower :bower install tomloprodModal或使用npm：npm install tomloprodModal
初始化：
Javascript：
TomloprodModal.start({
closeOut: true,
bgColor: "#FFFFFF",
textColor: "#333333"
});
模态窗口示例：
<div class="tm-modal tm-effect tm-draggable" id="logInPopUp">
<div class="tm-wrapper">
<div class="tm-title">
<span class="tm-XButton tm-closeButton"></span>
<h3 class="tm-title-text">Lorem Ipsum...</h3>
</div>
<div class="tm-content" >
<div style="text-align:center">
<img width="250" src="http://s3.favim.com/orig/47/animal-cat-cute-kitty-surprise-Favim.com-434324.jpg"/>
</div>
<p>
Lorem ipsum dolor sit amet, consectetuer adipiscing elit. Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et magnis dis parturient montes, nascetur ridiculus mus. Donec quam felis, ultricies nec, pellentesque eu, pretium quis, sem. Nulla consequat massa quis enim. Donec pede justo, fringilla vel, aliquet nec, vulputate eget, arcu. In enim justo, rhoncus ut, imperdiet a, venenatis vitae, justo. Nullam dictum felis eu pede mollis pretium. Integer tincidunt. Cras dapibus. Vivamus elementum semper nisi. Aenean vulputate eleifend tellus. Aenean leo ligula, porttitor eu, consequat vitae, eleifend ac, enim. Aliquam lorem ante, dapibus in, viverra quis, feugiat a, tellus. Phasellus viverra nulla ut metus varius laoreet. Quisque rutrum. Aenean imperdiet. Etiam ultricies nisi vel augue. Curabitur ullamcorper ultricies nisi. Nam eget dui. Etiam rhoncus. Maecenas tempus, tellus eget condimentum rhoncus, sem quam semper libero, sit amet adipiscing sem neque sed ipsum. Nam quam nunc, blandit vel, luctus pulvinar, hendrerit id, lorem. Maecenas nec odio et ante tincidunt tempus. Donec vitae sapien ut libero venenatis faucibus. Nullam quis ante. Etiam sit amet orci eget eros faucibus tincidunt.
</p>
</div>
</div>
</div>
结果：
或者，您可以创建没有任何 HTML 的模式窗口：
TomloprodModal.create({
bgColor: "#FFFFFF",
textColor: "#333333",
title: "Hi!",
content: "Nothing to say",
closeTimer: 1000
});

为此，我编写了一些简单的 JavaScript 函数，以及一个演示页面来向您展示如何使用它们。您可以在http://www.interbit.com/demos/modal.html查看。
我编写的函数称为 MsgBox()、YesNo() 和 YesNoCancel()。他们做他们名字所暗示的事情。
要使用它们，只需在上面的链接中复制 JavaScript 文件，并将其包含在您的 HTML 中。请不要只链接到文件。相反，复制它，因为我可以随时更改或删除它。
样品：
MsgBox("This is a message for the user.", "This is the title");
MsgBox("This is a message for the user.", "This is the title", "JSSnippetToCall();");
YesNo("Are you sure you want to do this?", "Please Confirm", "JSSnippetToCallOnYes();", "JSSnippetToCallOnNo();");
YesNoCancel("Are you sure you want to do this?", "Please Confirm", "JSSnippetToCallOnYes();", "JSSnippetToCallOnNo();", "JSSnippetToCallOnCancel();");
我还包含了一个名为 JavaScriptError() 的函数，它接受一个 JavaScript 错误对象并将其格式化以显示给用户，适合在 try/catch 块中使用：
try {
<your JavaScript code here>
} catch (e) {
JavaScriptError(e);
}
这是代码的完整列表，正如其中一位评论者所建议的那样。您可以将它包含在您的所有项目中。对于我希望你如何给予我信任，我有一些刻薄的评论，但实际上我所要求的只是普通的礼貌。我真的不打算起诉任何人，除非你窃取代码并声称是你编写的。

我不是 JavaScript 的粉丝，但这里有一个不错的跨浏览器模式窗口，它使用纯 HTML 和更简单的 JavaScript 来实现您所需要的：
- 此代码不需要 JQuery 或 Bootstrap
- 此代码适用于新旧浏览器，包括Internet Explorer 9
- 这段代码使用了几乎适用于所有浏览器的普通、老式的 JavaScript！
- 此代码使用新的 HTML5
<dialog>元素，并为不知道该元素的旧浏览器提供了简单的后备代码（在 2021 年，这将是一个相当长的列表！）
只需粘贴下面的 HTML 和 JavaScript 块并根据需要进行自定义。
