Set javascript variable from Ruby partial

Question

I have a very long operation that ends in a huge array. That array is passed as a Ruby object to a js.erb file which renders a partial using it:

$('#xxx').html("<%= escape_javascript(render('part', testVar: @fromServer)) %>");

This all goes well, but I'd like to be able to sort columns in the resulting table without having to re-do the entire operation. It should be easy, but I can't get the resulting variable in the partial to persist. My goal is to be able to have a script tag in the partial:

<script type="text/javascript">
    $("#column").click(function(){
        $.ajax({
              type : 'POST',
              url : '/sort_column',
              data : {data: jsVar},
              dataType : 'script'
        });
    });
</script>

How would I go about doing this?

Just wrap what you need from ruby in <%= %>. Like that:

data : {data: "<%= testVar %>"},

Since document will be send to ruby interpreter it will contain your testVar value. Also please use snake case notation instead of camel case. It's common agreement in ruby.

For whatever reason, the script just isn't being rendered. Is there some rule in Ruby about rendering scripts in partials?

If you don't getting errors then probably your controller logic works not as expected and not responding with js, could you add controller method to the question?
