Latex

Javascript backslash

For all equations written in javascript, remember to escape the \ with another \. \ by itself is an escape delimiter.

LaTeX.js

Code:

<!DOCTYPE html>

<head>

</head>

<body>

var text = 'The fraction is as such: $\\frac{\\sqrt{2}}{2}$'

var generator = new latexjs.HtmlGenerator({ hyphenate: false })

generator = latexjs.parse(text, { generator: generator })

document.head.appendChild(

generator.stylesAndScripts("https://cdn.jsdelivr.net/npm/latex.js@0.12.4/dist/"))

document.body.appendChild(generator.domFragment())

</script>

</body>

</html>

Code:

<!DOCTYPE html>

<html>

<head>

</head>

<body>

katex.render("c = \\pm\\sqrt{a^2 + b^2}", document.getElementById("container"), {

displayMode: true

});

</script>

</body>

</html>
