wordpress - Keep track of button hits for an rss feed carousel with jquery -


i'm making carousel puts posts various rss feeds number of divs (slides). 1 slide shows @ time, , have left , right button uses animate() move slides in appropriate direction. i'm showing 10 slides (numbered 0 9). i'd stop left button working when slide 9 displayed, , stop right button working when slide 0 displayed in order avoid whitespace showing. works far, can't find way keep track of slide i'm on in jquery script. here's have far: script included in section on wordpress site. id #1 refers carousel #1; #left , #right refer buttons.

$(document).ready(function(){  $("#1").data("slide_num",0);      $("#1 #left").click(function(){     if($("#1").data("slide_num") < 9){         $("#1 .item").animate({left: "-=800px"}, 250);         $("#1").html(function(){             var $this = $(this);             var $slide_num = $this.data("slide_num") + 1;             $this.data("slide_num",$slide_num);         });     }); });  $("#1 #right").click(function(){     if($("#1").data("slide_num") > 0){         $("#1 .item").animate({left: "+=800px"}, 250);           $("#1").html(function(){             var $this = $(this);             var $slide_num = $this.data("slide_num") - 1;             $this.data("slide_num",$slide_num);         });     }); });  });

what doing wrong? need store , keep track of variable on server-side? tried using variable named slide_num instead of .data() method, didn't work either. i'd appreciate on one.

php - Accessing static methods using newly created $obj or using class Name -

see class definition below: i using 5.3.9 version of php class a{ static function ab(){ echo "static function ab<br>"; } public function xy(){ echo "public function xy<br>"; } } $obj = new a(); $obj->ab(); a::ab(); both functions call give same output without error static function ab static function ab how possible static method can called class object? because static method calls using class name only?! now difference between accessing these 2 ways call static method ? referring php.net website declaring class properties or methods static makes them accessible without needing instantiation of class. property declared static can not accessed instantiated class object (though static method can). a big difference is because static methods callable without instance of object created, pseudo-variable $this not available inside method declared static. refer page php.net/manual/en/
