拓展Jquery对象，实现Post提交网页

$.extend({
            StandardPost:function(url,args){
                var body = $(document.body),
                    form = $("<form method=‘post‘></form>"),
                    input;
                form.attr({"action":url});
                $.each(args,function(key,value){
                    input = $("<input type=‘hidden‘>");
                    input.attr({"name":key});
                    input.val(value);
                    form.append(input);
                });

                form.appendTo(document.body);
                form.submit();
                document.body.removeChild(form[0]);
            }
        });
