django: how to pass template variable to javascript onclick routine?

This works

<div onclick="myFunction('{{ myVar }}')">

The only thing is that your myVar will become a string,

So if you need it as an object, an array... that's not what you need.

My solution:

1. create button pass this below properties

   <button type="button" onclick="check(varsize = '{{ size.sizeDes}}' ); return false type="btsize">`
   

2. write script on header part

   {% block javascript %}
   <script>
   function check(varsize) {
       document.getElementById("sizeid").value = varsize;
   }
   </script>
   {% endblock %}
