jquery trigger for window resize

I am positioning an element on the screen using jquery. I would like it to move when the window is resized.

Right now I have thi code, which works, but I was wondering if anyone knew how to rewrite it using .trigger so that I don't have to write the positioning twice.

var w = $(window).width();
var h = $(window).height(); 

$(".tour").css({"top": 50, "left" : (w - 950)/2}).click(function(){
    
    location.href = "guided-tour.php";
});    

$(window).resize(function(){
    w = $(window).width();
    h = $(window).height();
    $(".tour").css({"top": 50, "left" : (w - 950)/2});
});

Open in new window


Thanks!

Method 1:
var w = $(window).width();
var h = $(window).height(); 

a=function(){
$(".tour").css({"top": 50, "left" : (w - 950)/2}).click(function(){   
    location.href = "guided-tour.php";
});    
}

$(window).resize(a);
a();

Open in new window



Method 2 (I think it is better):
$(function () {
$(".tour").click(function(){
    location.href = "guided-tour.php";
});    
a=function(){
var w = $(window).width();
var h = $(window).height(); 
.css({"top": 50, "left" : (w - 950)/2})
}

$(window).resize(a);
$(window).trigget('resize');
})

I figured it out:

for anyone interested...

// define widths and heights globally for re-use...
var w = $(window).width();
var h = $(window).height();
var dh = $(document).height();

// position elements inside the resize, 
// and trigger resize to establish positioning on load.
$(window).resize(function(){

    w = $(window).width();
    h = $(window).height();

    $(".tour").css({"top": 50, "left" : (w - 950)/2});
    $(".navigation").css({"top": 100, "right" : (w - 950)/2});
    
}).trigger("resize");

// other functions...
$(".tour").click(function(){
    location.href = "guided-tour.php";
});
