我使用driver.js生成弹出窗口来显示页面。虽然MathJax适用于基本元素,但我不知道如何在弹出窗口上使用它。我跟踪了this answer,并试图在弹出窗口生成时重新运行MathJax,但我无法使其工作。
这里有一个小例子来描述这个问题:
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Files for MathJax -->
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
<!-- Files for driver.js -->
<script src="https://unpkg.com/driver.js/dist/driver.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/driver.js/dist/driver.min.css">
</head>
<body>
<p>
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
</p>
<button id="btn">Click to show popover</button>
<script>
// Define the popover
const driver = new Driver();
driver.defineSteps([
{
element: '#btn',
popover: {
title: 'Test MathJax',
description: 'When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]',
position: 'bottom'
}
}
]);
let btn = document.querySelector('#btn');
// When button is clicked, popover should appear and MathJax should re-run so that the math in the popover is correctly displayed
btn.addEventListener('click', function(){
driver.start();
MathJax.Hub.Queue(["Typeset", MathJax.Hub, "driver-popover-item"]);
});
</script>
</body>
</html>这可能是由于driver.js的构建方式造成的,但我在JavaScript方面没有足够的知识来亲自检查这一点,而且GitHub代码库目前看起来相当不活跃。
有没有人有主意?

虽然Eduardo Poco的答案适用于单一的popover,但它不适用于巡演中随后的popover的MathJax。此外,当执行“下一步”和“上一步”时(因此返回到应用MathJax的第一个弹出窗口),不再应用MathJax。
要将MathJax应用于所有driver.js弹出窗口(我猜其他导览库也有类似的功能),您可以使用onHighlighted在每个突出显示的弹出窗口上应用MathJax。
因此,我帖子中的示例变成了:
<!DOCTYPE html>
<html lang="en">
<head>
<!-- Files for MathJax -->
<script src="https://polyfill.io/v3/polyfill.min.js?features=es6"></script>
<script id="MathJax-script" async src="https://cdn.jsdelivr.net/npm/mathjax@3/es5/tex-mml-chtml.js"></script>
<!-- Files for driver.js -->
<script src="https://unpkg.com/driver.js/dist/driver.min.js"></script>
<link rel="stylesheet" href="https://unpkg.com/driver.js/dist/driver.min.css">
</head>
<body>
<p>
When \(a \ne 0\), there are two solutions to \(ax^2 + bx + c = 0\) and they are \[x = {-b \pm \sqrt{b^2-4ac} \over 2a}.\]
</p>
<button id="btn">Click to show popover</button>
<p id = "test2">Some text</p>
<script>
const driver = new Driver({
onHighlighted: () => {
setTimeout(function() {
MathJax.typeset();
}, 400);
}
});
driver.defineSteps([
{
element: '#btn',
popover: {
title: 'Test MathJax',
description: '\\(a \\ne 0\\), there are two solutions to \\(ax^2 + bx + c = 0\\) and they are \\[x = {-b \\pm \\sqrt{b^2-4ac} \\over 2a}.\\]',
position: 'bottom'
}
},
{
element: '#test2',
popover: {
title: 'Test MathJax',
description: '\\(a \\ne 0\\)',
position: 'bottom'
}
}
]);
let btn = document.querySelector('#btn');
btn.addEventListener('click', function(){
driver.start();
});
</script>
</body>
</html>注意:我将延迟设置为400ms,因为如果我设置一个较低的值,MathJax的应用速度太快(在弹出内容出现之前),因此内容不会被修改。这个值可能会为您更改(我尝试了几次才找到它)。

一些观察结果:
反斜杠()需要进行转义,以便它们出现在javascript中的字符串中。在HTML标记中不需要这样做。
在最新版本中重新运行MathJax的命令是MathJax.typeset()。我推迟了,这样司机就有机会让盒子出现。
