Dynamic google-code-prettify doesn't work

问题

Is it possible for a button to call a function that would 'prettify' a dynamic <code><pre>? I can't get it to work.

After the page loads, the initial <code> is prettified(?), but when I change it and call prettyPrint() afterwards, it no longer works.

Example: http://jsfiddle.net/uwBjD/2/

Edit: Sorry, I was using a local prettify.js. Updated it, still encountered the same error.

回答1:

Apparently after the code is prettified, an additional class is added which is prettyprinted. Anything with the class of prettyprinted is not re-prettified. You need to remove that class before recalling the function:

$('input[type=button]').click( function() {
    $("#jsExample").text("    var user = 'private'; //Do NOT store your API Key on a script.")
        .parent().removeClass("prettyprinted");

   prettyPrint();
});
