Using Ruby variable in Javascript (In App View)

Question

Currently, I have a ruby variable accessible by the view called @json (which contains information I need in JSON format)

However, I want to pass this into a script area such as

<script type="text/javascript" charset="utf-8">

//Want @json to be usable here

</script>

Is there any way to do this?

Answer 1

Assuming the script tag you mentioned is in a html erb view you can just use this:

<script type="text/javascript" charset="utf-8">
var json = <%= @json || 'null' %>;
</script>
