How to target specific letter/word with jquery?

As a mere example, I want to apply the class "fancy" to all occurrences of the sign "&" in the document.

The CSS:

.fancy { font-style: italic; }

So a text that looks like this:

Ben & Jerry's

would be manipulated by jquery to this:

Ben <span class="fancy">&amp;</span> Jerry's

Is there a function to target specific words/phrases/letters like this?

There's a "highlight" plugin that does almost exactly what you describe:

Regex is commonly used for this:

This isn't something that jQuery is generally helpful with--it works more at the node level than the text/html level. However, this might help (source):

$('p:contains(&)').each(function(){
  $(this).html(
    $(this).html().replace('&amp;','<span class=\'fancy\'>&amp;</span>')
  );
});

Obviously if you can restrict the initial search to something better than all paragraphs, it'd perform better. You should also test it to see if the :contains filter actually helps.

It's not pretty but it seems to work.
