Assign Ruby string value to Javascrip variable?

[cz]

Hi:

Is it possible to assign a ruby string value to a javascript variable?
I can display the ruby value on the browser. It looks fine, but when I
try to pass the value to a javascript variable, an error ocurrs
(unterminated string literal). The code snippet below is my attempt.

var str = '<%= #{@str} %>';

I also tried the Ajax approach and that didn't work either. I am knew
to Ruby, Sinatra, and Haml. That being said, I am surprised at how
difficult this stuff is. Java and pHP were much easier. Any help or
hints would be greatly appreciated. Thanks in advance.

yes you can, but where you are doing it, in the view.js.erb file?

i did something like these

<span class='progressBar' id='element<%= todo.id %>'
so the name id=elementWhatevercomefromdatabase

I expect this to work pretty will even in view.html.erb. As I write, I am
able to do this without problems as follows:

var userName = "<%= @user.name%>";

The question might be what is firing the bug, is it JS or Ruby? I suspect
the Ruby string that is being passed is incorrect.

I'm guessing the problem is that you're using string interpolation
syntax (#{...}), but outside of a double-quoted string. (Even if you
were to use double quotes in your JavaScript here, it wouldn't could,
because the erb expression is still not in Ruby quotes.) Just use:
