I am using MathJax to display some equations in an HTML document. What I want to do is explained in the following snippet:
<!DOCTYPE html>
<html>
<head>
<title>Math in HTML</title>
<meta charset="utf-8">
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']]
},
svg: {
fontCache: 'global'
}
};
</script>
<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>
</head>
<body>
<h1>Mathematic equations</h1>
<p>I cannot select this equation:
$$\intop_0^1f(x)dx=\pi$$
nor this one $x^2 + 3x - 2 = \zeta$.
</p>
<p>I would like that when someone copy-pastes the previous paragraph he/she would get:
<code>I cannot select this equation:
$$\intop_0^1f(x)dx=\pi$$
nor this one $x^2 + 3x - 2 = \zeta$.</code>
</body>
</html>
Basically I would like to make the math selectable and when copied into the clipboard to get the Latex code. Is this possible?

I am trying to learn JQuery running sample codes dealing with SetInterval or Settimeout I find on the Internet, but they won't run or work. For instance, I have the following simple code, but it won't run or even give me error message.
<!DOCTYPE html>
<html>
<head>
<title>testing</title>
<script type="text/javascript">
$(document).ready(function(){
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 333);
$('#here').load(number);
},
1000);
});
</script>
</head>
<body>
<div id="here">dynamic content ?</div>
</body>
</html>
You first missed to add jquery library and second you should use .text() function rather than .load() function.
.load() function should use for ajax method.
One of the essential rules that should keep in mind that always put javascript code at the end of the page and before the end of the body tag
$(document).ready(function() {
setInterval(function() {
var number = 1 + Math.floor(Math.random() * 333);
$('#here').text(number);
}, 1000);
});

I am using Mathjax to display equations in an HTML. This is my code:
<!DOCTYPE html>
<html>
<head>
<title>Math in HTML</title>
<meta charset="utf-8">
<script>
MathJax = {
tex: {
inlineMath: [['$', '$'], ['\\(', '\\)']]
},
svg: {
fontCache: 'global'
}
};
</script>
<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>
</head>
<body>
<h1>Mathematic equations</h1>
<p>I cannot select this equation:
$$\intop_0^1f(x)dx=\pi$$
nor this one $x^2 + 3x - 2 = \zeta$.
</p>
</body>
</html>
The problem is that I cannot select the equations. Previously I was using this in the header:
<script type="text/javascript" src="https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML"></script>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: {
inlineMath: [ ['$','$'], ["\\(","\\)"] ],
processEscapes: true
}
});
</script>
which produces "selectable equations" but raises a deprecation warning. (I tried to insert another snippet with this working example but StackOverflow complained it was too much code.)
I cannot find out how to convert the equations into "selectable".
You are correct that MathJax output can't be copied directly from the page in version 3. Version 3 uses CSS with content properties in order to insert the characters into the page, and content text is not selectable in the page.
In general, copying MathJax output would only be reliable with the simplest of expressions (nothing involving super- or subscripts, fractions, roots, arrays, multi-character stretchy delimiters, accents, etc.), so this was never a supported feature for MathJax.
On the other hand, it would be possible for MathJax to insert the characters directly rather than use content CSS, and an extension to implement that would be possible. Example code for doing that is available in the MathJax User's Forum.
So I am trying to make a binomial squared using code for a massive program I was attempting to get help with earlier. Since the code for the other program is huge I made a sub program to demonstrate what I am having issues with

var b = document.getElementById("Value_B").value
document.getElementById("Output").innerHTML = "$$(" + a + "-" + b + ")^2$$"
}
</script>

It runs in a browser just fine, but I cannot get the mathjax lib to work correctly after outputting the new equation
I needed to add in a piece of code that was missing

Took a while to find it, but I found it. Hopes this helps someone in the future it is the Mathjax piece of code you need
Hi I am new in reactjs when i am running server.js file from terminal it show blank page on browser. The code of index.html file is:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<script src="https://cdnjs.cloudflare.com/ajax/babel-
core/5.8.23/browser.min.js"></script>
<script

<script

</head>
<body>
<div id="app"></div>
<script type="text/babel">
ReactDOM.render(
<h1>Hello React!</h1>,
document.getElementById('app')
);
</script>
</body>
</html>
Thanks in advance.
This is a working example.
In your code, the wrong part is the CDN link to babel-core. You may always check your console when working with JS (on Google Chrome: Ctrl + shift + J on Windows, Cmd + Opt + J on IOS).
On the other hand, I thought this was a good opportunity to also introduce components (see ).
<!DOCTYPE html>
<html lang="en">

I am trying to learn how to display math equations with MathJax. I tweaked this code from codepen and this works fine:
`<!DOCTYPE html>
<head>
<script src='https://cdn.mathjax.org/mathjax/latest/MathJax.js?config=TeX-AMS-MML_HTMLorMML'></script>
<style>
p {
font-size: 22px;
}
</style>
</head><body>
<script type="text/x-mathjax-config">
MathJax.Hub.Config({
tex2jax: { inlineMath: [['$', '$']] },
elements: ['math']
});
</script>
<p id="math">
Find the value of:
$\Huge{\frac {3.41 \times 10^3}{1.80 \times 10^2}}$
and enter the answer within the box.
</p>
`
However, when I add one more paragraph and enter math in there, it does not display as math. It just displays like text. Any suggestions? Thank you.
Include your next paragraph id in the elements: ['math'] array in your MathJax config.
