CoffeeScripty code

gistfile1.coffee

$('#fixHead td.change').click (evt)->  # jQuery will automatically add the event handler to
                                       # every matching element, no need for $.each.
    evt.preventDefault()  # instead of returning false in an event handler
                          # (this is a general JS tip, not just CS)
    $this = $ this  # since you use $(this) twice, just keep it around
    $('#contactArea').load $this.data 'content'            # parentheses are optional...
    $("#ui-dialog-title-dialog").text($this.attr 'title')  # but still useful for clarity

    centerPopup()
    loadPopup()

    $('#popupContact').show()

    # P.S. Even if we were returning a value here the return keyword is optional--
    #      the value of the last expression is always returned in CoffeeScript.
