Question

Working through “Agile Web Development with Rails” edition 4 and hit the section on beginning AJAX. (Chapter 11 iteration F2). In the example code, the book using Rails 3.0 recommends creating:

app/views/line_items/create.js.rjs with the file only containing:

page.replace_html('cart', render(@cart))

What would an equivalent implementation for rails 3.1 using jQuery be?

app/views/line_items/create.js.erb?

$('#cart').html(?something magical here?)

Answer 1

You’d better do:

$('#cart').html("<%= escape_javascript(render(@cart)) %>");
