Question

I am having issues getting JQuery to be parsed by ruby.

For instance, the following line of code is supposed to add the @user’s username after the div with id ‘title.’

$('#title').after('<%= escape_javascript(@user.first.username') %>);

However, the output that I receive is a string that hasn’t been parsed at, complete with <

I haven’t found anything specifically posted on this on Stack Overflow and I’ve followed several tutorials unsuccessfully.

Thanks in advance for your help!

Answer 1

erb is parsed before the page loads, so this is inserting the erb code during javascript execution, which doesn’t get parsed at all. A better way to do this one would be to insert JS to set a variable, and then use that variable:

<script>
var myObj = "<%= escape_javascript(@user.first.username) %>";
$('#title').after(myObj);
</script>
