拓展Jquery对象，实现Post提交并跳转

$.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]);

            }

        });
