[SOLVED] How can I show multiple id as latex equation by using mathquill?

How can I show multiple id as latex equation by using mathquill?

I am trying to make a symbol palette where there will be an input field and I will click on a button that contains a latex symbol that will be the input in the field. As there will be multiple symbols, I am trying to use multiple buttons and MQ.StaticMath to show the latex equation. But the first id is accepting my latex output. Unfortunately, not the rest ids. I tried with class instead of id and using getElementByClassName in the script but not working as well. Here I am sharing my code and screenshots. Hoping someone can help me out with it.

<body>

<button id="symbol">\sqrt{}</button>
<button id="symbol">\frac{1}{2}</button>
<script>
    var symbols = document.getElementById('symbol');
    MQ.StaticMath(symbols);
</script>


</body>

And the output if I comment on one line another works perfectly but I need both or more to work.

As it's visible only one is working.

Solution

You have multiple button elements to handle. So you need to use js forEach.

<script>
   var MQ = MathQuill.getInterface(2);
   var symbols = document.querySelectorAll('#symbol');
   symbols.forEach(MQ.StaticMath);
</script>
