jQuery buttons?

gistfile1.js

$(document).ready(function(){
    var aInputs = $(":button");
    for(var i=0;i<aInputs.length;i++){
        var obj = $(aInputs[i]);
        if(obj.hasClass("vhm_btn_xsmall") || obj.hasClass("vhm_btn_small") || obj.hasClass("vhm_btn_medium") || obj.hasClass("vhm_btn_large")){
            obj.mousedown(function(){
                var o = $(this);
                var sClass = o.attr("class").toLowerCase();
                o.removeClass(sClass);
                o.addClass(sClass + "_on");
            });
            obj.mouseup(function(){
                var o = $(this);
                var sClass = o.attr("class").toLowerCase();
                o.removeClass(sClass);
                o.addClass(sClass.replace("_on",""));
            });
        }
    };
    var aInputs = $(":submit");
    for(var i=0;i<aInputs.length;i++){
        var obj = $(aInputs[i]);
        if(obj.hasClass("vhm_btn_xsmall") || obj.hasClass("vhm_btn_small") || obj.hasClass("vhm_btn_medium") || obj.hasClass("vhm_btn_large")){
            obj.mousedown(function(){
                var o = $(this);
                var sClass = o.attr("class").toLowerCase();
                o.removeClass(sClass);
                o.addClass(sClass + "_on");
                
            });
            obj.mouseup(function(){
                var o = $(this);
                var sClass = o.attr("class").toLowerCase();
                o.removeClass(sClass);
                o.addClass(sClass.replace("_on",""));
            });
        }
    }
});
