rendering $..$ and macros not work

See original GitHub issue

Hi. I have followed all the instructions to render with $ .. $ and it does not work. And neither when creating my macros

<body> <script> $(document).ready(function() { katex.render(formula, element, { delimiters: [ {left: "$$", right: "$$", display: true}, {left: "\\[", right: "\\]", display: true}, {left: "$", right: "$", display: false}, {left: "\$", right: "\$", display: false} ], macros: { // Algebra-Precal "\\lcm": "\\mathop{\\mathrm{lcm}}", "\\sen" "\text{sen}\\", // Calculus "\\dd": "\\mathop{\\mathrm{d} #1}", "\\abs": "\\lvert#1\\rvert", } }); }); </script> </body>

the page with this problem is https://prob.matematicauniversitaria.com/

in the CSS I only have:

p{ font-family: times new roman; /*Latin Modern Math*/ font-size: 100% } .katex{ font-size: 1.10em; /*1.16em dicen q es el 100%*/ }

and in the head I have the same thing that it provides https://katex.org/docs/autorender.html

What should I correct? Thanks in advance.

Thank you. Now I can see that it renders perfectly with the macros.

I used

  renderMathInElement(document.body, {
    delimiters: [
    {left: "$$", right: "$$", display: true},
    {left: "\\[", right: "\\]", display: true},
    {left: "$", right: "$", display: false},
    {left: "\\(", right: "\\)", display: false} ],
    macros: {
      // Algebra-Precal
      "\\lcm": "\\mathop{\\mathrm{lcm}}",
      "\\sen": '\\text{sen}\\,',
      // Calculus
      "\\dd": "\\mathop{\\mathrm{d} #1}",
      "\\abs": "\\lvert #1 \\rvert",
      }
  });
 }); </script>

in the <body>

Best regards!

You aren’t loading katex properly with your document.ready code, it looks like you aren’t loading jquery so you can’t use $(document).ready(. I have put a fixed version below. You should also remove onload="renderMathInElement(document.body);" or maybe even the whole katex auto-render load line, as currently you are loading katex twice.

  document.addEventListener("DOMContentLoaded", function() {
  renderMathInElement(document.body, {
    delimiters: [
    {left: "$$", right: "$$", display: true},
    {left: "\\[", right: "\\]", display: true},
    {left: "$", right: "$", display: false},
    {left: "\\(", right: "\\)", display: false} ],
    macros: {
      // Algebra-Precal
      "\\lcm": "\\mathop{\\mathrm{lcm}}",
      "\\sen": '\\text{sen}\\,',
      // Calculus
      "\\dd": "\\mathop{\\mathrm{d} #1}",
      "\\abs": "\\lvert #1 \\rvert",
      }
  });
 });
