I'm able to render partial inside a modal using escape_javascript in js.erb file code:

$("body").append("<%= escape_javascript(render partial: 'example_partial') %>");
$('#my_modal').modal('show');

However, I can't seem to get results for:

console.log(<%= @error %>)

• 1 You need to put inverted mas around the ruby helper. console.log('<%= @error %>') – Sinan Guclu Commented Jul 15, 2016 at 9:23

ERB will output a plain string. JS needs inverted mas around a string for it to be recognized. You have missed them on your console.log() statement.

Change it to:

console.log('<%= @error %>');

You may also find the raw helper useful. This will call .to_s and .html_safe on any erb output:

console.log('<%= raw @error %>');
