Jquery string filtering
===

I'm doing a little fancy snippet of js to automatically copy the value of a textbox into a later span.

    <input name="data[ask_admin_name]" onkeyup=
        "$("#admin_name").html($(this).val())"
    type="text" id="ask_admin_name">

and then, later, 

    <span id="admin_name"></span>

What is the fastest, easiest, most jquery-est way to strip html-related tags out of this, like `<` and `>`?

I could do it using some more lines of js, but I'm wondering if there's a specific function for this task, for example, `$(this).val().strip('<>');`?
