• Bugzilla : No SASL mechanism found

  - by niteshsinha

  I am using Bugzilla on windows 7. I am using the unofficial Bugzilla installer. I followed the steps accordingly and gave valid credentials wherever required. I open Bugzilla and try to create a new account , but i get the following error. Software error: No SASL mechanism found at C:/Program Files/Bugzilla/perl/perl/site/lib/Authen/SASL.pm line 77 at C:/Program Files/Bugzilla/perl/perl/lib/Net/SMTP.pm line 143 i ran checksetup.pl and found that Authen::SASL and SMTP both are available on my machine.

• Google.com and clients1.google.com/generate_204

  - by David Murdoch

  I was looking into google.com's Net activity in firebug just because I was curious and noticed a request was returning "204 No Content." It turns out that a 204 No Content "is primarily intended to allow input for actions to take place without causing a change to the user agent's active document view, although any new or updated metainformation SHOULD be applied to the document currently in the user agent's active view." Whatever. I've looked into the JS source code and saw that "generate_204" is requested like this: (new Image).src="http://clients1.google.com/generate_204" No variable declaration/assignment at all. My first idea is that it was being used to track if Javascript is enabled. But the "(new Image).src='...'" call is called from a dynamically loaded external JS file anyway, so that would be pointless. Anyone have any ideas as to what the point could be? UPDATE "/generate_204" appears to be available on many google services/servers (e.g., maps.google.com/generate_204, maps.gstatic.com/generate_204, etc...). You can take advantage of this by pre-fetching the generate_204 pages for each google-owned service your web app may use. Like This: window.onload = function(){ var two_o_fours = [ // google maps domain ... "http://maps.google.com/generate_204", // google maps images domains ... "http://mt0.google.com/generate_204", "http://mt1.google.com/generate_204", "http://mt2.google.com/generate_204", "http://mt3.google.com/generate_204", // you can add your own 204 page for your subdomains too! "http://sub.domain.com/generate_204" ]; for(var i = 0, l = two_o_fours.length; i < l; ++i){ (new Image).src = two_o_fours[i]; } };

• jQuery live draggable / live droppable?

  - by Henk

  Hi all, Basically there are two tables: Companies and visitors. Currently it's possible to drag visitors to companies. Works great. As soon as the drop function occurs, there are two $.post's. The first one saves the drag to the database. The second one updates the visitors, because the information constantly changes. The problem, however is that as soon as the second $.post finishes, Firebug keeps popping the following error: d(this).data("draggable") is null Which occurs in the jQuery UI file. On line 56. about 400 times or so. So basically I'm looking for a way to do live() with draggable and droppable. The .draggables are in #visitors (an ul). The droppables are in #companies (a table). Thanks! $(".draggable").draggable({ revert:true }); $(".droppable").droppable({ drop: function(ev, ui) { $(this).text($(ui.draggable).text()); $.post('planning/save_visit', {user_id: $(ui.draggable).attr('id'), company_id: $(this).attr('id'), period: $('ul.periods li.active').attr('id')}); $.post('planning/' + $('ul.periods li.active').attr('id'), {visitors:true}, function(data){ $('#visitors').html(data); }); }, hoverClass: 'drophover' });

• ASP.NET MVC returning ContentResult using Ajax form - how to preserve whitespace?

  - by Ben

  In my application users can enter commands that are executed on the server. The results are added to a session object. I then stuff the session object into ViewData and add it to a textarea. When done with a standard HTML form whitespace is preserved. However, when I swap this out for an ajax form (Ajax.BeginForm) and return the result as ContentResult, the whitespace is removed. Controller Action: [HttpPost] public ActionResult Execute(string submitButton, string command) { if (submitButton == "Clear") { this.CurrentConsole = string.Empty; } if (submitButton == "Execute" && !string.IsNullOrEmpty(command)) { var script = new PSScript() { Name = "Ad hoc script", CommandText = command }; this.CurrentConsole += _scriptService.ExecuteScript(script); } if (Request.IsAjaxRequest()) { return Content(this.CurrentConsole, "text/plain"); } return RedirectToAction("Index"); } View: <fieldset> <legend>Shell</legend> <%=Html.TextArea("console", ViewData["console"].ToString(), new {@class = "console", @readonly = "readonly"})%> <% using (Ajax.BeginForm("Execute", new AjaxOptions { UpdateTargetId = "console", OnBegin = "console_begin", OnComplete = "console_complete"})) { %> <input type="text" id="command" name="command" class="commandtext" /> <input type="submit" value="Execute" class="runbutton" name="submitButton" /> <input type="submit" value="Clear" class="runbutton" name="submitButton" /> <%} %> </fieldset> How can I ensure that whitespace is preserved? When I inspect the response in FireBug it looks like the whitespace is transmitted, so can only assume it has something to do with the way in which the javascript handles the response data.

• jquery.ui.draggable.js and jquery.ui.widget.js conflict

  - by Daniel S

  hello I had a working application, which uses a jquery ui dialog. I wanted to make the dialog draggable. As far as I know the only thing needed is the jquery.ui.draggable.js script. So I added it to the scripts I am using, but know I get the following error (as shown in the firebug console): base is not a constructor The relevante line in jquery.ui.widget.js is: var basePrototype = new base(); This is how I am adding all the scripts: <script type="text/javascript" src="/media/development-bundle/jquery-1.4.2.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.core.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.widget.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.draggable.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.position.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.autocomplete.js"></script> <script type="text/javascript" src="/media/development-bundle/ui/jquery.ui.dialog.js"></script> Am I doing something wrong? or is this a problem with jquery? Thanks in advance for any help

• getJSON not working if the mvc model view controller has a parameter

  - by Paul

  I'm having an issue with a callback. I'm not even getting an error in Firebug. If I alert before and after the getjson call both alerts show but the getjson call doesn't fire. public ActionResult TestPage() { return View(); } public ActionResult LoadMapLonLats(int mapId) { //some code return Json(_myMaps); } $("#Search").click(function() { $.getJSON("LoadMapLonLats", { mapId: 73 }, loadDbMap); }); function loadDbMap(maps) { alert('m'); $.each(maps, function(i) { alert(maps[i]); }); } As long as I leave TestPage without a parameter is works. If I add a parameter to TestPage(int id) then the call back to LoadMapLonLats doesn't work. Seems odd. Of course TestPage is the page I'm loading so I need to do some work here before rendering the page. Not sure why adding a parameter to the view would break the callback to another function. //this breaks he callback to LoadMapLonLats public ActionResult TestPage(int id) { return View(); } Any ideas? Seems like this may be related, if not sorry I can post a new thread.

• Problem with jqGrid in Internet Explorer 8

  - by Dave Swersky

  I have developed an ASP.NET MVC (version 2 RC) application with a ton of jqGrids. It's working like a champ in Firefox, but I've discovered a problem in IE8. The "Main View" grids can be filtered by a search box or one of a few dropdowns above the grid. I use some javascript to reset the url for the grid, then trigger a reload, thusly: function filterByName(filter) { if (filter == 'All') { $('#list').setGridParam({ url: 'Application/GetApplications' }); $('#list').trigger("reloadGrid"); } else { $('#list').setGridParam({ url: 'Application/GetAppByName/' + filter + '/' }); $('#list').trigger("reloadGrid"); } } This works like magic in Firefox, but I'm getting an HTTP 400 Bad Request when I do this in IE8. The IE8 client-side debugger is like flint and tinder compared to Firebug's flamethrower, so I'm not having much luck figuring out why it breaks in IE8. Has anyone seen this? Also, the jqGrid "trigger" method here is swallowing the AJAX exception. Is there a way to get it to bubble up so I can get to the exception details? UPDATE: The problem was with the syntax in my "onchange" event for the dropdowns. I was using: onchange="filterByMnemonic($('#drpMnemonic')[0].value); Which Firefox apparently doesn't mind but IE sees that as nuthin'. This, however, works in both browsers: onchange = "filterByMnemonic($('#drpMnemonic > option:selected').attr('value'));"

• Jqgrid: navigation based on the selected row

  - by bsreekanth

  Hello, I was trying to enable navigation based on a selected row. So, the user select a row from jQgrid, and when press the show (is there a show button for the grid, I saw edit, add etc), it needs to go to a new page based on the url (part of the row). $(document).ready(function () { function getLink() { // var rowid = $("#customer_list").jqGrid('getGridParam', 'selrow'); var rowid = $("#customer_list").getGridParam('selrow'); var MyCellData = $("#customer_list").jqGrid('getCell', rowid, 'dataUrl'); return MyCellData; } $("#customer_list").jqGrid({ url:'mytestList', editurl:'jq_edit_test', datatype: "json", colNames:['Call Id','Title','dataUrl'], colModel:[ {name:'callId', width:80, search:false }, {name:'title', width:200, sortable:false }, {name:'dataUrl',hidden:true} ], rowNum:10, sortname:'lastUpdated', sortorder: 'desc', pager:'#customer_list_pager', viewrecords: true, gridview: true }).navGrid('#customer_list_pager', {add:true,edit:true,del:false,search:true,refresh:true}, {closeAfterEdit:true, afterSubmit:afterSubmitEvent }, // edit options {addCaption:'Create New something', afterSubmit:afterSubmitEvent, savekey:[true,13]}, // add options {afterSubmit:afterSubmitEvent} // delete options ); $("#customer_list").jqGrid('filterToolbar'); }); so, the url is passed for each row as dataUrl. I'm trying to read it and set to the button. Whn debug through firebug, the rowid was 223 (there were only 12 rows in the grid), and the cell value is empty. Currently the button is kept outside the grid, but it may better to be it part of the vavGrid thanks.

• Jquery.get() not returning any data

  - by David Waters

  Hi I am trying to scrape other people web pages (for the forces of good not evil). I am currently trying to do this with javascript/jquery from with in a browser. I am finding that the no data is returned from the jquery.get() success call back function. My code. $.get('http://www.google.co.uk/', function (data, textStatus, XMLHttpRequest){ alert("status " + textStatus); alert('data:' + data); window.data=data; window.textStatus=textStatus; window.httpReq = XMLHttpRequest}); In my mind this should simply do a get on google store the data in window.data and we are all good. What happens is we get textStatus == success and data == "". the status on the XMLHttpRequest is 4(success). I have looked at the network traffic using a transparent proxy (Charles) and everything looks find there http status 200 plenty of data being returned. I am running this just from the Firebug console in Firefox. Any ideas?

• HTML Agility Pack Screen Scraping XPATH isn't returning data

  - by Matthias Welsh

  I'm attempting to write a screen scraper for Digikey that will allow our company to keep accurate track of pricing, part availability and product replacements when a part is discontinued. There seems to be a discrepancy between the XPATH that I'm seeing in Chrome Devtools as well as Firebug on Firefox and what my C# program is seeing. The code I'm currently using is pretty quick and dirty... //This function retrieves data from the digikey private static List<string> ExtractProductInfo(HtmlDocument doc) { List<HtmlNode> m_unparsedProductInfoNodes = new List<HtmlNode>(); List<string> m_unparsedProductInfo = new List<string>(); //Base Node for part info string m_baseNode = @"//html[1]/body[1]/div[2]"; //Write part info to list m_unparsedProductInfoNodes.Add(doc.DocumentNode.SelectSingleNode(m_baseNode + @"/table[1]/tr[1]/td[1]/table[1]/tr[1]/td[1]")); //More lines of similar form will go here for more info //this retrieves digikey PN foreach(HtmlNode node in m_unparsedProductInfoNodes) { m_unparsedProductInfo.Add(node.InnerText); } return m_unparsedProductInfo; } Although the path I'm using appears to be "correct" I keep getting NULL when I look at the list "m_unparsedProductInfoNodes" Any idea what's going on here? I'll also add that if I do a "SelectNodes" on the baseNode it only returns a div... not sure what that indicates but it doesn't seem right.

• dijit tree and focus node

  Hello, I cannot get focusNode() or expandNode() get working. I also tried switching back to dojo 1.32 and even 1.3, no difference to 1.4.

• Integrating Google Analytics into GWT application

  - by Domchi

  This should be totally simple but I can't get it working no matter what I try. I'm trying to use Google Analytics with GWT application. From what I understood, there are two way to do it: First is synchronous, by inserting tracking code at the end of <head> section HTML page and then calling this method: public static native void recordAnalyticsHit(String pageName) /*-{ pageTracker._trackPageview(pageName); }-*/; Second is asynchronous, by inserting tracking code just after <body> tag and then calling this method: public static native void recordAnalyticsHit(String pageName) /*-{ _gaq.push(['_trackPageview(' + pageName + ')']); }-*/; When running each of those methods, however, I get this exceptions in hosted mode: [ERROR] [myproject] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): pageTracker is not defined [ERROR] [myproject] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (ReferenceError): _gaq is not defined When observing site in Firebug, I see that ga.js gets loaded, but that's about it. Did anyone get Analytics working with GWT? Also, does _gaq accept page name as trackPageview parameter, since all the examples I've seen use this call: _gaq.push(['_trackPageview()']); (Of course, that also doesn't work for me.)

• dojo.xhrPost and Zend Framwork action, no POST data, not using a form

  - by sims

  Hi all, I'm trying to send some data via dojo.xhrPost to an Zend Controller Action. I can see the data being sent in Firebug console. However, when inspecting the post data, the array is empty. I'm not sure if it is possible to send an arbitrary string of data via dojo.xhrPost without using a form. This is probably a very n00b mistake. In any case, I'll post my code here and see what you all think. In my layout script I have: <?php $sizeurl = $this->baseUrl() . '/account/uisize'; ?> function resizeText(multiplier) { if (document.body.style.fontSize == "") { document.body.style.fontSize = "1.0em"; } document.body.style.fontSize = parseFloat(document.body.style.fontSize) + (multiplier * 0.1) + "em"; var size = document.body.style.fontSize; var xhrArgs = { url: "<?= $sizeurl; ?>", postData: size, handleAs: "text" } dojo.xhrPost(xhrArgs); } Then my action is: public function uisizeAction() { $this->_helper->viewRenderer->setNoRender(); $this->_helper->layout->disableLayout(); print_r($_POST); $request = $this->getRequest(); if ($request->isXmlHttpRequest()) { $postdata = $request->getPost(); print_r($postdata); if ($postdata) { $user = new Application_Model_DbTable_User(); $user->updateSize($postdata); } } } I'm pretty sure that post data from a form is an array with the form elements' names as the keys. When looking at the dojo.xhrPost examples on the dojo campus web site (http://docs.dojocampus.org/dojo/xhrPost second one to be precise), it looks as if I can just send a string of data. How do I access this data from a Zend Controller Action? I'm using ZF 1.10 and Dojo 1.4.2 Thanks for your help! PS I'd try to ask on one of the related questions, but I cannot seem to comment.

• CSS positioning is weird when reducing the viewport

  - by Lars Hanke

  I have a little meditation for you ... I run a site using a liquid tri-col layout with a header. The layout runs nicely since more than a decade with all browsers I ever dared to try. It is based on absolute positioning in CSS. This page provides an example of the actual site. Watching the page from my tablet I found that the right column overlaps the center matter. Further investigation using Firebug showed that once the center content reaches 360px width, the right margin of the div shrinks. Why is that? Since Firefox and Android render the same, I guess that this is something, which is actually supposed to be. However, I tried to make virtue out of necessity and experimented setting min-width for body and content and made the body scroll overflow. The body actually scrolls, but the right column is positioned on the right edge of the viewport instead of the body element (Firefox). Is this intentional CSS standard? Any ideas how to solve the presentation on small displays? Thanks for your efforts,  – lars.

• jQuery upload file using jQuery's ajax method (without plugins)

  - by Daniil Harik

  Hello, At moment I want to implement picture upload without using any plug-ins. My upload form looks like this <form action="/Member/UploadPicture" enctype="multipart/form-data" id="uploadform" method="post"> <span style="display: none;"> <div class="upload" id="imgUpl"> <h3>Upload profile picture</h3> <div class="clear5"></div> <input type="file" name="file" id="file" /> <button class="btn-bl" id="upComplete"><span>Upload</span></button> </div> </span> </form> And my jQuery code is: $('#upComplete').click(function () { $('#up').hide(); $('#upRes').show(); var form = $("#uploadform"); $.ajax({ type: "POST", url: "/Member/UploadPicture", data: form.serialize(), success: function (data) { alert(data); } }); $.fancybox.close(); return false; }); If I open firebug, I can see that ajax() method does simple form post (not multi-part) and POST content is empty Is it possible to do files upload using jQuery ajax() method or should I do this in any other way? Thank You very much

• DOM: element created with cloneNode(true) missing element when added to DOM

  - by user149327

  I'm creating a tree control and I'm attempting to use a parent element as a template for its children. To this end I'm using the element.cloneNode(true) method to deep clone the parent element. However when I insert the cloned element into the DOM it is missing certain inner elements despite having an outerHTML value identical to its parent. Surprisingly I observe the same behavior is in IE, Firefox, and Chrome leading me to believe that it is by design. This is the HTML for the node I'm attempting to clone. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf> <IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> Once I've cloned the node using cloneNode(true) I examine the outerHTML property and find that it is indeed identical to the original. <SPAN class=node><A class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf><IMG class=nodeIcon alt="Taylor Swift" src="images/node.png"><SPAN class=nodeText>Taylor Swift</SPAN></A><SPAN class=nodeDescription>Taylor Swift is a swell gall who is realy great.</SPAN></SPAN> However when I insert it into the DOM and inspect the result using FireBug I find that the element has been transformed: <span class="node" style="top: 0px; left: 0px;"<a class=nodeLink href="/SparklerRestService2.aspx?q={0}" name=http://dbpedia.org/data/Taylor_Swift.rdf>Taylor Swift</a><span class="nodeDescription">It's great</span></span> Notice that the grandchildren of the node (the image tag and the span tag surrounding "Taylor Swift") are missing, although strangely the great grandchild "Taylor Swift" text node has made it into the tree. Can anyone shed some light on this behavior? Why would nodes disappear after insertion into the DOM, and why am I seeing the same result in all three major browser engines?

• Why is the UpdatePanel Response size changing on alternate requests?

  - by Decker

  We are using UpdatePanel in a small portion of a large page and have noticed a performance problem where IE7 becomes CPU bound and the control within the UpdatePanel takes a long time (upwards of 30 seconds) to render. We also noticed that Firefox does not seem to suffer from these delays. We ran both Fiddler (for IE) and Firebug (for Firefox) and noticed that the real problem lied with the amount of data being returned in update panel responses. Within the UpdatePanel control there is a table that contains a number of ListBox controls. The real problem is that EVERY OTHER TIME the response (from making ListBox selections) alternates from 30K to 430K. Firefox handles the 400+K response in a reasonable amount of time. For whatever reason, IE7 goes CPU bound while it is presumably processing this data. So irrespective of whether or not we should be using an UpdatePanel or not, we'd like to figure out why every other async postback response is larger by a factor of more than 10 than the previous one. When the response is in the 30K range, IE updates the display within a second. On the alternate times, the response time is well over 10 times longer. Any idea why this alternating behavior should be happening with an UpdatePanel?

• jQuery AJAX slow in Firefox, fast in IE

  - by Brandon Montgomery

  I'm using jQuery to post to an ASP .NET Web Service to implement a custom auto-complete function. The code works great, except it's slow in FireFox (can't get it to go faster than 1 second). IE is blazing fast - works great. I watch the post in Firefox using Firebug. Here's the service code: <ScriptService(), _ WebService(Namespace:="http://tempuri.org/"), _ WebServiceBinding(ConformsTo:=WsiProfiles.BasicProfile1_1), _ ToolboxItem(False)> _ Public Class TestWebSvc Inherits System.Web.Services.WebService <WebMethod(), _ ScriptMethod(ResponseFormat:=Script.Services.ResponseFormat.Json, UseHttpGet:=True)> _ Public Function GetAccounts(ByVal q As String) As Object 'Code taken out for simplicity Return result End Function End Class And the jQuery ajax call: $.ajax({ beforeSend: function (req) { req.setRequestHeader("Content-Type", "application/json"); }, contentType: "application/json; charset=utf-8", type: "GET", url: "http://localhost/Suggest/TestWebSvc.asmx/GetAccounts", data: "q='" + element.val() + "'", dataType: "json", success: testWebSvcSuccess }); As you can see, I've tried to use the HTTP GET verb instead in hopes that that would make the call faster. As it does not, I'll probably switch it back to using POST if I can. Right now I'm just focused on why it's super fast in IE and super slow in Firefox. Versions: jQuery 1.3.2; Firefox 3.0.11; IE 8.0.6001.18783 (64-bit) Thank you for any insight you can provide.

• Using a dynamic <script> (a <script> appended to the DOM by JavaScript) to load and initialize Click

  - by Bungle

  I'm creating an HTML/JavaScript widget to be used on third-party sites. This widget is generated by a <script> that our customers will insert on their page. The <script> creates an <iframe> in the customer's domain, and then creates and inserts all of that <iframe>'s content using JavaScript. It's important that this <iframe> contain Clicky's tracking code to monitor clicks on outbound links. Unfortunately, I'm not having any luck getting Clicky to work when I append the requisite <script> elements to the <iframe> using JavaScript. I first tried simply appending the Clicky tracking code to the <iframe> after appending some test outbound links, hoping that Clicky could attach to those automatically as it does on a static page. That didn't seem to work, so my next inclination was to use the "advanced_disable" custom option and use clicky.log() on the links I want to track. Here's a link to a test page that's along those lines: http://onespot.wsj.com/static/clicky_iframe_test.html When clicking a link on that test page, the action is not logged in Clicky, and a JavaScript error appears: clicky is not defined This ("clicky") appears to be defined in http://static.getclicky.com/js, which I confirmed through the Firebug console is indeed loading before I click a test outbound link. Has anyone successfully loaded Clicky in this way? If so, could you provide some sample code, a link to a working implementation, or some feedback on what's wrong with my code? I would also be interested to know if this is even possible. Thanks very much for any help or advice!

• empty response body in ajax (or 206 Partial Content)

  - by Nikita Rybak

  Hi guys, I'm feeling completely stupid because I've spent two hours solving task which should be very simple and which I solved many times before. But now I'm not even sure in which direction to dig. I fail to fetch static content using ajax from local servers (Apache and Mongrel). I get responses 200 and 206 (depending on the server), empty response text (although Content-Length header is always correct), firebug shows request in red. Javascript is very generic, I'm getting same results even here: http://www.w3schools.com/ajax/tryit.asp?filename=tryajax_first (just change document location to 'http://localhost:3000/whatever') So, it's probably not the cause. Well, now I'm out of ideas. I can also post http headers, if it'll help. Thanks!

• jQuery AutoComplete Plugin not working for JSON Response (sValue.substring is not a function)

  - by Sunday Ironfoot

  I'm trying to use the autocomplete plugin for jQuery (this one http://docs.jquery.com/Plugins/Autocomplete). My server is returning JSON string, which I'm trying to process on the client via AutoComplete plugin's 'parse' and 'formatItem' parameters, like so: $(document).ready(function() { $('.searchBox input.textbox').autocomplete('/DoSearch.aspx', { mustMatch: false, autoFill: true, minChars: 1, dataType: 'json', parse: function(data) { var array = new Array(); for (var i = 0; i < data.length; i++) { array[array.length] = { data: data[i], value: data[i].ID, result: data[i].ID }; } return array; }, formatItem: function(row, i, n) { return row.ID + ': ' + row.Title; } }); }); When I run this I get a 'sValue.substring is not a function' error thrown in Firebug. However, if I stick breakpoints on formatItem and parse function, they are hit as expected and contain valid data it seems. Here is an exact copy 'n' paste of the JSON text that gets returned from the server: [{"ID":140177,"Title":"Food Handling","Code":"J01.576.423.200"},{"ID":140178,"Title":"Food Handling","Code":"J01.576.423.200"},{"ID":140179,"Title":"Brain Infarction","Code":"C10.228.140.300.301.200"},{"ID":140180,"Title":"Cerebral Hemorrhage","Code":"C10.228.140.300.535.200"},{"ID":140182,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140183,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140184,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140186,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140188,"Title":"Insulin","Code":"D06.472.610.575"},{"ID":140189,"Title":"Sulfonylurea Compounds","Code":"D02.886.590.795"}] Please help, I've already searched Google and StackOverflow for help, but can't find anyone having else this error, cheers!

• jQuery Drag/Drop problem: mousemove Event not binding for some elements

  - by saturdayplace

  Using the latest jQuery/UI that are hosted at Google. I've got the following markup: <ul id="tree"> <li><a href="1/">One</a></li> <li><a href="2/">Two</a></li> </ul> And the following javascript: $(document).ready(function(){ // Droppable callbacks function dragOver(overEvent, ui_object) { $(this).mousemove(function(moveEvent){ console.log("moved over", this); }); } function drop_deactivate() { $(this).unbind(); } function drag_out() { $(this).unbind(); } // Actual dragging $("#treeContainer li").draggable({ revert: true, revertDuration: 0 }); // Actuall dropping $("a").droppable({ tolerance: "pointer", over: dragOver, deactivate: drop_deactivate, out: drag_out }); }); If I drag the first li down over the second, the mousemove function fires (and firebug logs the output). But if I drag the second li up over the first, the mousemove function doesn't fire. You can see this live at http://jsbin.com/ivala. Is there a reason for this? Should I be trapping the mousemove event in some other way? Edit: It appears as thought the mousemove() event isn't binding for earlier elements than the one currently being dragged (should be bound upon their mouseover).

• Still confused about JavaScript's 'this'.

  - by Nick Lowman

  I've been reading through quite a few articles on the 'this' keyword when using JavaScript objects and I'm still somewhat confused. I'm quite happy writing object orientated Javascript and I get around the 'this' issue by referring the full object path but I don't like the fact I still find 'this' confusing. I found a good answer here which helped me but I'm still not 100% sure. So, onto the example. The following script is linked from test.html with <script src="js/test.js"></script> if (!nick) { var nick = {}; } nick.lowman = function(){ var helloA = 'Hello A'; console.log('1.',this, this.helloA); var init = function(){ var helloB = 'Hello B'; console.log('2.',this, this.helloB); } return { init: init } }(); nick.lowman.init(); What kind of expected to see was 1. Object {} nick.lowman, 'Hello A' 2. Object {} init, 'Hello B' But what I get is this? 1. Window test.html, undefined 2. Object {} init, undefined I think I understand some of what's happening there but I would mind if someone out there explains it to me. Also, I'm not entirely sure why the first 'console.log' is being called at all? If I remove the call to the init function //nick.lowman.init() firebug still outputs 1. Window test.html, undefined. Why is that? Why does nick.lowman() get called by the window object when the html page loads? Many thanks

• AS3 "Loader" progress immediately goes to 100%

  - by Bart van Heukelom

  If you go to http://moederdagontbijtplacemat.nl/ you will see a progress bar. The application is loading a fairly large SWF from the server using the Loader class. Strangely enough, the progress bar immediately goes to 100% (but the loading still takes a while after that). The code is below, but you'll see it's basically too simple to break. It has worked when the application was on a different server, so I though maybe the new server wasn't sending the size of the large SWF in the http headers. Firebug does show a progress bar though, so that is not the case, the information should be available. It also works when I run the loader swf locally and change the URL (new URLRequest("Placemat.swf")) to the absolute URL of Placemat.swf on the server. var l:Loader = new Loader(); addChild(l); l.contentLoaderInfo.addEventListener(ProgressEvent.PROGRESS, function(e:ProgressEvent) { s.setProgress(e.bytesLoaded/e.bytesTotal); trace(Math.round(100 * e.bytesLoaded/e.bytesTotal), "%"); }); l.contentLoaderInfo.addEventListener(Event.COMPLETE, function() { removeChild(s); }); l.load(new URLRequest("Placemat.swf"));
