How would i sequence the following code so one line runs after the previous ?

```
$('#jqNav li a').click(function(e){

    if($(this).parent().is(".nav1")){ $('.landing .main .nav ul').css({ "background-position" : "0 -50px" });} 
    else if($(this).parent().is(".nav2")) { $('.landing .main .nav ul').css({ "background-position" : "0 -100px" });}
    else if($(this).parent().is(".nav3")) { $('.landing .main .nav ul').css({ "background-position" : "0 -150px" });}
    else if($(this).parent().is(".nav4")) { $('.landing .main .nav ul').css({ "background-position" : "0 -200px" });};

    stopAnim = true;
    $page = $(this).attr('href');
    var $hashTag = $(this).attr('name');
    window.location.hash = $hashTag;
    loadData();
    $(window).scrollTop(0);
    e.preventDefault();

});

```
