jquery在調整大小之前保存寬度

Question

如何在此代碼中將一個子句添加到變量中，然後每次調整大小？

$(window).on('load resize', function() {   
     var w = $(window).width(); 
     var h = $(window).height(); 

     $('#right1').css('top' , w > 1250 ? -120 : -73); 

    }); 

Answer 1

var oldW = $(window).width(); 
var oldH = $(window).height(); 

$(window).on('load resize', function() { 
    var w = $(window).width(); 
    var h = $(window).height(); 

    $('#right1').css('top', w > 1250 ? -120 : -73); 

    //Finish what you want with oldH and oldW.... 
    oldH = h; 
    oldW = w; 
});
