Question

I’ve included a script in jQuery, but it doesn’t seem to work. Can you take a look at the code and enlighten me?

<div id="foo"></div>

$('#foo').append('<script> some code </script>');

Answer 1

Seeing as you are using javascript to insert some javascript, why not just run the javascript snippet:

!function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs");

Where you have:

$('#foo').append(...);

Just insert that code from Twitter. It will do the same thing.
