How to add an error notice with jquery?

Question

Been trying to add a custom error notice with jquery, but so far the div looks funky

jQuery('h1').prepend('<div class=\"error\">Start</div>');

Any tips how to get this to work? As I understand Drupal uses the error div.

Answer 1

Drupal uses messages as the 'base' class for messages so this should work:

jQuery('h1').prepend('<div class="messages error">Start</div>');

Note that you shouldn't escape double quotes inside a string unless the string is actually wrapped in double quotes.
