javascript - multiple instances of valums file uploader -


i'm trying multiple instances of valum file uploader working on site. works great 1 instance anytime loop on initialization code, wanting multiple buttons don't see buttons. here's code:

<cfoutput query="gettopics">  <script>             function createuploader(){                     var uploader = new qq.fileuploader({             element: document.getelementbyid('file-uploader#reftopicid#'),             action: 'components/projectbean.cfc',             params: {method: 'upload',                     topicid: #reftopicid#,                     count: #evaluate("session.#reftopicabv#count")#,                     topicname: '#reftopicabv#'                     },             encoding: 'multipart'         });                }      // in app create uploader dom ready     // don't wait window load       window.onload = createuploader;      </script>  <div class="row" id="file-uploader#reftopicid#">         </div>

any idea how multiple instance? in advance!

you're creating javascript function inside of loop. in other words you're defining multiple times.

instead should move createuploader function outside of loop. , within loop, call multiple times each of topics.

something this:

<script>             function createuploader(elementid, topicid, topiccount, topicname){                     var uploader = new qq.fileuploader({             element: document.getelementbyid(elementid),             action: 'components/projectbean.cfc',             params: {method: 'upload',                     topicid: topicid,                     count: topiccount,                     topicname: topicname                     },             encoding: 'multipart'         });                }    </script>  <cfoutput query="gettopics"> <script>             createuploader('file-uploader#gettopics.reftopicid#', #gettopics.reftopicid#, #session[gettopics.reftopicabv & "count"]#, '#gettopics.reftopicabv#');    </script>  <div class="row" id="file-uploader#gettopics.reftopicid#"> </div> </cfoutput>

nb: i'm assuming values come query gettopics, i've prefixed them query name scope them properly. isn't essential, it's practice performance reasons (among other things).

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/
