How to send values from form.php to view.js?

Permalink
I have very simple script for mansory grid gallery. I want to control the number of cols from the form. "The problem" i dont know how to set the values dynamic like this.

Install like this:
<script type="text/javascript">
   Macy.init({
   container: '#macy-container',
   margin: 12,
   columns: 3,
   }
});   
</script>


If i install the script inside view.php it wont work. Get error:
"1087 Uncaught ReferenceError: Macy is not defined(…)"

There are several ways to do it. This is just one.

Attach them to a dom element as data attribute data-whatever="value", either individually or as a json string. Then in your js, look for the attribute and get the values from it.

Nice idea. Do you have some code example (i use jquery)?
