jquery - Applying Slidesjs slide on Knockout binded image list -


when try apply slidesjs (carousel-like) slide animation on image list (shown below), error appears , images stacked on no slide animation. tried image slider on knockout binded image list fed web api?

uncaught typeerror cannot read property 'style' of undefined (at slidescontrol[0].style[transform] below)

 if (this.data.vendorprefix) {       prefix = this.data.vendorprefix;       transform = prefix + "transform";       duration = prefix + "transitionduration";       timing = prefix + "transitiontimingfunction";       error line-->slidescontrol[0].style[transform] = "translatex(" + direction + "px)";       ...[script goes on]

error occurs because there no style attribute on slidescontainer[0], there no slidescontainer either beacuse set as: 

slidescontrol = $(".slidesjs-control", $element)

so problem why slidesjs-control not generated slidesjs plugin. idea?

edit (a hint)

i have discovered when slidesjs plugin initializes, there no element in #slider div. knockout should have filled before slidesjs starts. because knockout code comes first. when typed $("#slider") on console in init method of slidesjs , hit enter:

<div id="slider" data-bind="foreach: banners" style="overflow:hidden;"></div>

my html:

<div class="webtv">   <div class="slidebox">     <div id="slider" data-bind="foreach: banners">       <a data-bind="attr: { href: $data.href, target: $data.target }">         <img data-bind="attr: { src: $data.imageurl }" width="728" height="288" alt="" />       </a>     </div>   </div> </div>

my slidesjs script:

$(window).load(function() {   $('#slider').slidesjs({     width: 728,     height: 288   }); });

my knockout script:

function bannerviewmodel() {   var self = this;   self.banners = ko.observablearray([]);   var baseuri = '/api/home/getsliderbanners';   $.getjson(baseuri, function (data) {     self.banners(data.sliderbanners);   }); }  $(document).ready(function () {   ko.applybindings(new bannerviewmodel(), document.getelementbyid('slider')); });

i try following , see if can data first , pass in constructor view model. 

function bannerviewmodel(sliderbanners) {   var self = this;   self.banners = ko.observablearray(sliderbanners); }  $(document).ready(function () {   var baseuri = '/api/home/getsliderbanners';   var sliderbanners;   $.getjson(baseuri, function (data) {     sliderbanners = data.sliderbanners);   });   ko.applybindings(new bannerviewmodel(sliderbanners), document.getelementbyid('slider')); });

getjson asynchronous may have check returns data before applybindings.

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/
