Is there away to get something unique on a client computer? I read about ActiveX but it is only works on IE. I need something that can work on other browsers also, maybe on PHP or on Javascript.

<p>Current Images Inside Gallery <br /> <?php foreach($rows as $row): ?> <div class="t"> <table class="table2"> <tr> <td class="table2"><?php echo $row["id"]; ?></td> </tr> <tr> <td><img src="images/<?php echo $row["photo"] ; ?>" alt="" width="130" height="130" /></td> </tr> <tr> <td><textarea class="js-copyfilename" readonly="readonly" ><?php echo $row["photo"];?></textarea> <button class="js-copyfilenamebtn">Copy Filname</button> </td> </tr> </table> </div> <?php endforeach;?> </div> <script type="text/javascript"> var copyfilenameBtn = document.querySelector('.js-copyfilenamebtn'); copyfilenameBtn.addEventListener('click', function(event) { var copyfilename = document.querySelector('.js-copyfilename'); copyfilename.select(); try { var successful = document.execCommand('copy'); var msg = successful ? 'successful' : 'unsuccessful'; console.log('Copying text command was ' + msg); } catch (err) { console.log('Oops, unable to copy'); } }); </script> I am trying to create a button so the user can copy `$filename` then paste it into a field (this part I will code after this is sorted) I have this code which works but it only works for the first row I understand that I will need array the that this is because I would probably need to array the js-copyfilename and js-copyfilenamebtn classes so each one is different but i know very little about JavaScript so would know where to start Thanks in advance

I have some routines I use over and over Is there a way to put the error section in a file of its own For example I use a routine below <script type="text/javascript"> $('.MYTRIGGER').live('change', function() { var MyData=''; $("#jq_tab").val('0'); var NameData=$(this).attr('name'); var IdData=$(this).attr('id'); MyData=MyData+'CID='+NameData;; MyData=MyData+'&Field='+IdData; MyData=MyData+'&FieldValue='+$(this).val(); $.ajax( { cache:false, timeout:28000, url : 'MyPhp.php', type : 'post', data : MyData, success : function( resp ) { $("#jq_tab").val('1'); return(false); }, error: function(xhr, status, error) { var stat = $("#jq_tab").val(); $("#main_page_div").unmask_div(); if(stat!='1'){ if (xhr.status === 0) { alert('Unable to connect to Network'); } else if (xhr.status == 404) { alert('Requested page not found. [404]'); } else if (xhr.status == 500) { alert('Internal Server Error [500].'); } else if (exception === 'parsererror') { alert('Requested JSON parse failed.'); } else if (exception === 'timeout') { alert('System Timeout (Internet Congestion or server slow)'); } else if (exception === 'abort') { alert('Ajax request aborted.'); } else { alert('Unspecified Error #' + xhr.responseText); } } return false; } // eof error function }); }); </script> Since the below is common error: function(xhr, status, error) { var stat = $("#jq_tab").val(); $("#main_page_div").unmask_div(); if(stat!='1'){ if (xhr.status === 0) { alert('Unable to connect to Network'); } else if (xhr.status == 404) { alert('Requested page not found. [404]'); } else if (xhr.status == 500) { alert('Internal Server Error [500].'); } else if (exception === 'parsererror') { alert('Requested JSON parse failed.'); } else if (exception === 'timeout') { alert('System Timeout (Internet Congestion or server slow)'); } else if (exception === 'abort') { alert('Ajax request aborted.'); } else { alert('Unspecified Error #' + xhr.responseText); } } return false; } // eof error function Is there a way to store the error function in a common file?

I have tried other players and am now testing the mediaelement.js player, which works in all browsers, playing the video, and shows the 'poster' image in all browsers, except no 'poster' image appears in IE8. As I know the "poster' isn't supported by IE8, I'm looking for help with a work-around to place a thumbnail image as a substitute (for IE8) for the 'poster' image. Any help will be appreciated. Here's my current code: <video id="video" poster="http://www.-domain-.com/img/testImage.jpg" preload="none" controls="controls" width="240" height="220" > <source type="video/mp4" src="http://www.-domain-.com/video/testVideo.mp4"/> <object width="240" height="220" type="application/x-shockwave-flash" data="http://www.-domain-.com/mediaelement/flashmediaelement.swf"> <param name="movie" value="http://www.-domain-.com/mediaelement/flashmediaelement.swf" /> <param name="flashvars" value="controls=true&file=http://www.-domain-.com/video/testVideo.mp4" /> <!-- Image as a last resort --> <img src="http://www.-domain-.com/img/testImage.jpg" width="240" height="220" title="No video playback capabilities" /> </object> </video>

Hi all, I need some guidance on how I can build an AJAX/PHP chat application, sort of like an instant messaging thing like the one on Facebook. It doesn't have to be anything fancy as long as it works. I have some ideas as to how I can build it but I've never tried to do anything like this before so I'm a bit lost. I'm confident I can build the entire PHP side of things up until I have to use AJAX, then I'm stuck. The main concern I have is the affect it will have on the server, lets say I have a Javascript timer to check for new messages sent at certain intervals, wouldn't that have a massive affect on the server? I can only think of using a timer to get new messages for each user, I can't come up with any other way to get it to work. I just don't want to kill the server with AJAX requests if that's even possible. So really my question is, would it be okay to use a timer to get new messages of each user at certain intervals, or is there another way of doing it? Hope this makes sense Thanks, Adam

Hello, I could not figure wether this question should be posted in the javascript forum or here. I am building a simple blog commenting application that displays a comment reply box whose textarea has a dynamically generated ID when a reply link is clicked Take a look at my html code below: <div> <div> Some message over here </div> <div style = "height:10px;"> <a class="reply" id="myHeader1" href="javascript:showonlyone('newboxes1');" >Reply</a></div> </div> <div class ="replymsgbox" id="newboxes1"> <form method="POST"> <textarea id="" class="content"></textarea> </form> </div> <div> <div> Some message over here </div> <div style = "height:10px;"> <a class="reply" id="myHeader2" href="javascript:showonlyone('newboxes2');" >Reply</a></div> </div> <div class="replymsgbox" id="newboxes2"> <form method="POST"> <textarea id="" class="content" ></textarea> </form> </div> And this is the javascript dynamically generating the ID: The javascript script below uses the parent(); children() and next() jquery methods to traverse the DOM and select the textarea element of the displayed form so as to assign the 'ID attribute' to it. <script type="text/javascript"> $('a.reply').on("click", function(e){ $(this).parent("div").parent("div").next("div").children('form').children('textarea').attr( "id", "ckeditor" ); }); </script> When the reply link is clicked, the comment box with a form is toggled using the jquery show() and hide() functions. See code snippet below: <script src="views/js/jquery-1.11.2.min.js" type="text/javascript"></script> <script type="text/javascript"> function showonlyone(thechosenone) { $('.replymsgbox').each(function(index) { if ($(this).attr("id") == thechosenone) { $(this).show(200); } else { $(this).hide(600); } }); } </script> I then wish to replace the dynamic (textarea id="comment") with a CKEditor instance using the code below: <script src="libraries/ckeditor/ckeditor.js"></script> <script type="text/javascript"> $(document).ready(function() { if(CKEDITOR) { // Replace the <textarea id= "ckeditor"> with a CKEditor instance. CKEDITOR.replace('ckeditor'); } }); </script> However, when I toggle the comment form, (the id="ckeditor") attribute is assigned, but what appears is a simple textarea not with ckeditor enabled on it. How can I make each new dynamically created textareas use CKeditor? or Why is the CKEDITOR replace() method not detecting the textarea ID? Perhaps someone here may have any clues? Note: that when I hardcode the id='ckeditor' attribute value pair into any of the text areas, that textarea is converted into a rich text editor.
