• Java Script – Content delivery networks (CDN) can bit you in the butt.

  - by Ryan Ternier

  As much as I love the new CDN’s that Google, Microsoft and a few others have publically released, there are some strong gotchas that could come up and bite you in the ass if you’re not careful. But before we jump into that, for those that are not 100% sure what a CDN is (besides Canadian).   Content Delivery Network. A way of distributing your static content across various servers in different physical locations.  Because this static content is stored on many servers around the world, whenever a user needs to access this content, they are given the closest server to their location for this data. Already you can probably see the immediate bonuses to a system like this: Lower bandwidth Even small script files downloaded thousands of times will start to take a noticeable hit on your bandwidth meter. Less connections/hits to your web server which gives better latency If you manage many servers, you don’t need to manually update each server with scripts. A user will download a script for each website they visit. If a user is redirected to many domains/sub-domains within your web site, they might download many copies of the same file. When a system sees multiple requests from the same  domain, they will ignore the download   Those are just a handful of the many bonuses a CDN will give you. And for the average website, a CDN is great choice. Check out the following CDN links for their solutions: Google AJAX Library: http://code.google.com/apis/ajaxlibs/ Microsoft Ajax library: http://www.asp.net/ajaxlibrary/cdn.ashx The Gotcha There is always a catch. Here are some issues I found with using CDN’s that hopefully can help you make your decision. HTTP / HTTPS If you are running a website behind SSL, make sure that when you reference your CDN data that you use https:// vs. http://. If you forget this users will get a very nice message telling them that their secure connection is trying to access unsecure data. For a developer this is fairly simple, but general users will get a bit anxious when seeing this. Trusted Sites Internet Explorer has this really nifty feature that allows users to specify what sites they trust, and by some defaults IE7 only allows trusted sites to be viewed.  No problem, they set your website as trusted. But what about your CDN? If a user sets your websites to trusted, but not the CDN, they will not download those static files. This has the potential to totally break your web site. Pedantic Network Admins This alone is sometimes the killer of projects. However, always be careful when you are going to use a CDN for a professional project. If a network / security admin sees that you’re referencing an outside source, or that a call from a website might hit an outside domain.. panties will be bunched, emails will be spewed out and well, no one wants that.

• SWFObject and IE6 causing hair-pulling agony

  - by Piet

  I recently used SWFObject to display a flash header on a website. I chose SWFObject because: Instead of displaying an annoying ‘Install flash now’ message, it claims to be able to show alternate content. In this case: the original header image. It claims to be compatible with more or less every browser out there. Implementation went fine, until someone tested it on IE6 and got the following error: Internet explorer cannot open the Internet site http://www….. Operation aborted Which basically means that the site just can’t be visited with IE6 (still used a lot in business environments), it even seems as if there’s something wrong with your internet connection. Now, since about 10% of visitors to this site are still using IE6 (why does everyone still use Internet Explorer ???? Do YOU know that these days most people do NOT use Internet Explorer anymore ?) Now after some googling, I found the suggestion to defer loading of the SWFObject.js as follows: <script type="text/javascript" defer=”defer” src=”http://ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js” </script> <script type=”text/javascript” defer=”defer” swfobject.registerObject(”myId”, “9″, “”); </script> What this does according to W3C: When set, this boolean attribute provides a hint to the user agent that the script is not going to generate any document content (e.g., no “document.write” in javascript) and thus, the user agent can continue parsing and rendering. I don’t know exactly why, but: HURRAY! It works now!!! Only… IE6 and IE7 (didn’t try IE8) now gave the following error: Line: 19 Char: 1 Error: ’swfobject’ is undefined Code: 0 URL: http://www… But the flash was still running fine. Still, such an error isn’t clean, especially since almost half of the site’s visitors are using one of these Internet Explorer versions. Now, wanting a quick fix I decided to do the following: <script type="text/javascript" defer="defer" if (typeof(swfobject) != "undefined") swfobject.registerObject("myId", "9", ""); </script> I admit this is a bit of a weird ‘fix’. You’d suspect the flash to stop working on IE6/IE7, which it doesn’t. Not planning on diving into it’s inner bowels, I regard this a ‘mission accomplished’ until someone somewhere posts a better solution (for which I setup some Google alerts). Do you have a better solution? What would be the impact on the webdev economy (or your life) if all browsers were compatible? Addendum Because the above turned out not to work with the new Firefox 3.5.3 (strangely, was OK with 3.5.2 when I tested it) I decided to cut the crap and use the ‘Dynamic Publishing’ way. Ok, so it won’t work for people who have javascript disabled, but who on earth would have flash installed AND javascript disabled? To avoid the IE6 error with the ‘Dynamic Publishing’ way, I call swfobject.embedSWF right after the div that will be replaced with the flash content. Calling swfobject.embedSWF in the <head> would otherwise give me the above error in IE6 again.

• Mandatory look back at 2010

  - by Bertrand Le Roy

  Yeah, it's one of those posts, sorry. First, the mildly depressing: the most popular post on this blog this year with 47,000 hits was a post from last year about a fix to a bug in ASP.NET. A content-less post except for that link to the KB article that people should have found by going directly to the support site in the first place. Then, the really depressing: the second most popular post this year with 34,000 hits was a post from 2005 about how to display message boxes on a web page. I mean come on. This was kind of fun five years ago and it did solve one of the most common n00b mistakes VB programmers trying to move to the web were making. But come on, we've traveled about 4.7 billion miles around the Earth since then. Do people still do that kind of stuff? I should probably put a big red banner on top of this post. Oh [supernatural entity of your choice]. Hand me that gun, please. Third most popular post with 24,000 hits is from 2004. It's about how to set a session variable before redirecting. That problem has been fixed a long time ago. Oh well. Fourth most popular post. 21,000 hits. 2007. How to work around a stupid bug in ASP.NET Ajax 1.0. Fixed in ASP.NET 3.5? ASP.NET Ajax 1.0? Need I say more? The fifth one (20,000 hits) is an old post as well but I'm kind of fond of it: it's about that photo album handler I've been organically growing for a few years. It reminds me that I need to refresh it and make a new release. Good SEO title too. Back to insanity with the sixth one (16,000) that's about working around a bug in IE6. IE6. Please just refuse to pander to that browser any more. It's about time. Let's move on, please. Actually, the first post from 2010 is 15th in the list. We have a trio of these actually with server-side image resizing and FluentPath. So what happened? Well, I like the ad money, but not to the point that I'm going to write my stuff to inflate it. Actually I think if I tried I would fail miserably (I mean, I would fail worse). What really happened this year was new stuff: Orchard, FluentPath and the stuff with the Netduino. That stuff needs time to get off the ground but my hope is that it's going to be useful in the long run and that five years from now I'll be lamenting on how well those posts are still doing. So, no regret. 2010 was a good year. Oh, and I was on This Developer's Life this year! Yay! Anyways, thank you all for reading me. Please continue doing that. And happy 2011!

• Can you/should you develop components for ASP.NET MVC?

  - by Vilx-

  Following from the previous question I've started to wonder - is it possible to implement "Components" in ASP.NET MVC (latest version)? And should you? Let's clarify what I mean with a "component". With that I mean a "control" (aka "widget"), similar to those that ASP.NET webforms is built upon. A gridview might be a good example. In webforms I can place on my form a datasource component (one line of code), a gridview component (another line of code) and bind them together (specify an attribute on the gridview). In the codebehind file I fill the datasource with data (a few lines of DB-querying code), and I'm all set. At this point the gridview is a fully functional standalone component. I can open the form, and I'll see all the data. I can sort it by clicking on the column headers; it is split into several pages; I can drag the column headers around and rearrange columns; I can turn on "grouping" mode; etc. And I don't need to write another line of code for any of it. The gridview, as a component, already has all the code tucked away in its classes and assemblies. I just place it on the form, initialize it, and it Just Works. At some times (like sorting or navigation to a different page) it will also perform ajax callbacks to the server, but those too will be handled internally, with my code having no knowledge at all about it. And then there are also events that I can attach if I want to get notified when something happens. In MVC I cannot see a way of doing this cleanly. Sure, there are the partial views, but those only handle half of the problem - they render the initial HTML. Some more can be achieved with client-side Javascript (like column re-arranging), but when the grid needs to do an ajax callback (say, to fetch the next page of data), my code will have to get involved and process that request. At best I guess I can provide some helper methods to process it, but I'll have to write the code that calls them, and also provide a controller method with signature matching the arguments of that callback. I guess that I could make some hacks with global events or special routes or something, but that just seems... hackish. Unelegant. Perhaps this is not the MVC way? Although I've completed one project in it, I'm still far from being an MVC expert. But then what is? In the intranet application that we're building there are dozens upon dozens of such grids. Naturally I want them all to have a unified look & behavior, and I don't want to repeat the same code all over the place. So what's the "MVC" approach to this problem?

• Using 3rd Party JavaScript Plugins Hardwired With &lsquo;document.write&rsquo;

  - by ToStringTheory

  Introduction Have you ever had the need to implement a 3rd party JavaScript plugin, but your needs didn’t fit the model and usage defined by the API or documentation of the plugin?  Recently I ran into this issue when I was trying to implement a web snapshot plugin into our site.  To use their plugin, you had to include a script tag to the plugin on their server with an API key.  The second part of the usage was to include a <script> tag around a function call wherever you wanted a snapshot to appear. The Problem When trying to use the service, the images did not display.  I checked a couple of things and didn’t find anything wrong at first..  It wasn’t until I looked at the function that was called by the inline script did I find the issue – a call to the webservice, followed by a call to ‘document.write’ in its callback.  The solution in which I was trying to implement the plugin happened to be in response to an AJAX call after the document had completely loaded.  After the page has loaded, document.write does nothing. My first thought for a solution was to just cache the script from the service, and edit it do something like a return function or callback that I could use to edit the document from.  However, I quickly discovered that there is no way to cache the script from the service, as it had a hash in the function where it would call the server.  The hash was updated every few seconds/minutes, expiring old hashes.  This meant that I wouldn’t be able to edit the script and upload a new version to my server, as the script would not work after a few minutes from originally getting the script from the service. Solution The solution eluded me until I realized that this was JavaScript I was dealing with.  A language designed so that you could do just about anything to any library, function, or object…  At this point, the solution was simple – take control of the document.write function.  Using a buffer variable, and a simple function call, it is eerily simple to perform: //what would have been output to the document var buffer = ""; //store a reference to the real document.write var dw = document.write; //redefine document.write to store to our buffer document.write = function (str) {buffer += str;} //execute the function containing calls to document.write eval('{function encapsulated in <script></script> tags}'); //restore the original document.write function (just in case) document.write = dw; That’s it.  Instead of using the script tags where I wanted to include a snapshot, I called a function passing in the URL to the page I wanted a snapshot of.  After that last line of code, what would have been output to the document (or not in the case of the ajax call) was instead stored in buffer. Conclusion While the solution itself is simple, coming from a background much more footed in the .Net platform, I believe that this is a prime example of always keeping the language that you are working in in mind.  While this may seem obvious at first, as I KNEW I was in JavaScript, I never thought of taking control of the document.write function because I am more accustomed to the .Net world.  I can’t simply replace the functionality of Console.WriteLine.

• JavaScriptSerializer().Serialize(Entity Framework object)

  - by loviji

  May be, it is not so problematic for you. but i'm trying first time with json serialization. and also read other articles in stackowerflow. I have created Entity Framework data model. then by method get all data from object: private uqsEntities _db = new uqsEntities(); //get all data from table sysMainTableColumns where tableName=paramtableName public List<sysMainTableColumns> getDataAboutMainTable(string tableName) { return (from column in _db.sysMainTableColumns where column.TableName==tableName select column).ToList(); } my webservice: public string getDataAboutMainTable() { penta.DAC.Tables dictTable = new penta.DAC.Tables(); var result = dictTable.getDataAboutMainTable("1"); return new JavaScriptSerializer().Serialize(result); } and jQuery ajax method $('#loadData').click(function() { $.ajax({ type: "POST", url: "WS/ConstructorWS.asmx/getDataAboutMainTable", data: "{}", contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { $("#jsonResponse").html(msg); var data = eval("(" + msg + ")"); //do something with data }, error: function(msg) { } }); }); problem with data, code fails there. and i think i'm not use JavaScriptSerializer().Serialize() method very well. Please, tell me, what a big mistake I made in C# code?

• jQuery "Microsoft JScript runtime error: Object expected"

  - by Oskar Kjellin

  I have the below code that does not seem to work at all :( I keep getting: Microsoft JScript runtime error: Object expected The error seems to occur when the timeout is done. So if I raise the timeout with 10 seconds the error holds for another 10 seconds. I want to be able to update the number of friends online async. The number is shown with the following html: <a href="" id="showChat" >Friends online <strong id="friendsOnline">(?)</strong></a> The friends part is set at the first run, but when the timeout calls back it does not fire again. Also, I cannot see on which line the error occurs because if I want to break on the error it just shows "no source code" etc. The code below is the code I'm using. Thanks! <script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.3.2.js" type="text/javascript"></script> <script src='/Scripts/MicrosoftAjax.js' type="text/javascript"></script> <script src='/Scripts/MicrosoftMvcAjax.js' type="text/javascript"></script> <script src='/Scripts/jquery.autocomplete.js' type="text/javascript"></script> <script type="text/javascript"> $(document).ready(function() { UpdateFriendsOnline(); function UpdateFriendsOnline() { window.setTimeout("UpdateFriendsOnline()", 1000); $.get("/Account/GetFriendsOnline", function(data) { $("#friendsOnline").html("(" + data + ")"); }); } }); </script>

• How to do server-side validation using Jqgrid?

  - by Eoghan

  Hi, I'm using jqgrid to display a list of sites and I want to do some server side validation when a site is added or edited. (Form editing rather than inline. Validation needs to be server side for various reasons I won't go into.) I thought the best way would be to check the data via an ajax request when the beforeSubmit event is triggered. However this only seems to work when I'm editing an existing row in the grid - the function isn't called when I add a new row. Have I got my beforeSubmit in the wrong place? Thanks for your help. $("#sites-grid").jqGrid({ url:'/json/sites', datatype: "json", mtype: 'GET', colNames:['Code', 'Name', 'Area', 'Cluster', 'Date Live', 'Status', 'Lat', 'Lng'], colModel :[ {name:'code', index:'code', width:80, align:'left', editable:true}, {name:'name', index:'name', width:250, align:'left', editrules:{required:true}, editable:true}, {name:'area', index:'area', width:60, align:'left', editable:true}, {name:'cluster_id', index:'cluster_id', width:80, align:'right', editrules:{required:true, integer:true}, editable:true, edittype:"select", editoptions:{value:"<?php echo $cluster_options; ?>"}}, {name:'estimated_live_date', index:'estimated_live_date', width:120, align:'left', editable:true, editrules:{required:true}, edittype:"select", editoptions:{value:"<?php echo $this->month_options; ?>"}}, {name:'status', index:'status', width:80, align:'left', editable:true, edittype:"select", editoptions:{value:"Live:Live;Plan:Plan;"}}, {name:'lat', index:'lat', width:140, align:'right', editrules:{required:true}, editable:true}, {name:'lng', index:'lng', width:140, align:'right', editrules:{required:true}, editable:true}, ], height: '300', pager: '#pager-sites', rowNum:30, rowList:[10,30,90], sortname: 'cluster_id', sortorder: 'desc', viewrecords: true, multiselect: false, caption: 'Sites', editurl: '/json/sites' }); $("#sites-grid").jqGrid('navGrid','#pager-sites',{edit:true,add:true,del:true, beforeSubmit : function(postdata, formid) { $.ajax({ url : 'json/validate-site/', data : postdata, dataType : 'json', type : 'post', success : function(data) { alert(data.message); return[data.result, data.message]; } }); }});

• jQuery WCF Service MVC2 VS2010 .NET 4.0 call with parameters fails

  - by AUSTX_RJL

  In Visual Studio 2010 I created a new Ajax enabled WCF Service [ServiceContract(Namespace = "TestWCFAjax.Bridge")] [AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)] public class Bridge { [OperationContract] public string DoWork() { return "jQuery WCF call without parameters from MVC2 works." ; } [OperationContract] public string DoWork1(string parm) { return parm + " jQuery WCF call with parameters from MVC2 fails"; } In the Home Controllers Index.aspx view I add the jQuery: function CallWebMethod() { $.ajax( { type: "POST", contentType: "application/json; charset-utf-8", url: "http://localhost:1452/Bridge.svc/DoWork1", dataType: "json", data: '{"parm":"test"}', error: jqueryError, success: function (msg) { alert("back"); var divForResult = document.getElementById("test"); divForResult.innerHTML = "Result: <b>" + msg.d + "</b>"; } }) } function jqueryError(request, status, error) { alert(request.responseText + " " + status + " " + error); } (using the built-in Web Server in VS 2010) When I call DoWork, it works fine. When I call DoWork1 it always returns "error undefined" and the WCF call never happens. I've tried every combination of: [WebInvoke(Method = "POST", BodyStyle = WebMessageBodyStyle.WrappedRequest, ResponseFormat = WebMessageFormat.Json, RequestFormat = WebMessageFormat.Json)] I can think of and it does not help. I must be missing something simple. There are MANY posting about how to make this work, and other than the "no parameter" version, none have worked for me. Can anyone post a sample MVC2 jQuery 1.4 .NET 4.0 WCF VS2010 working sample or spot the likely error? Thanks.

• Model validation with enumerable properties in Asp.net MVC2 RTM

  - by Robert Koritnik

  I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors.

• Django - The included urlconf doesn't have any patterns in it

  - by unsorted

  My website, which was working before, suddenly started breaking with the error "ImproperlyConfigured at / The included urlconf resume.urls doesn't have any patterns in it" The project base is called resume. In settings.py I have set ROOT_URLCONF = 'resume.urls' Here's my resume.urls, which sits in the project root directory. from django.conf.urls.defaults import * # Uncomment the next two lines to enable the admin: from django.contrib import admin admin.autodiscover() urlpatterns = patterns('', # Example: # (r'^resume/', include('resume.foo.urls')), # Uncomment the admin/doc line below and add 'django.contrib.admindocs' # to INSTALLED_APPS to enable admin documentation: (r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin: (r'^admin/', include(admin.site.urls)), (r'^accounts/login/$', 'django.contrib.auth.views.login'), #(r'^employer/', include(students.urls)), (r'^ajax/', include('urls.ajax')), (r'^student/', include('students.urls')), (r'^club/(?P<object_id>\d+)/$', 'resume.students.views.club_detail'), (r'^company/(?P<object_id>\d+)/$', 'resume.students.views.company_detail'), (r'^program/(?P<object_id>\d+)/$', 'resume.students.views.program_detail'), (r'^course/(?P<object_id>\d+)/$', 'resume.students.views.course_detail'), (r'^career/(?P<object_id>\d+)/$', 'resume.students.views.career_detail'), (r'^site_media/(?P<path>.*)$', 'django.views.static.serve', {'document_root': 'C:/code/django/resume/media'}), ) Anyone know what's wrong? This is driving me crazy. Thanks,

• Extjs Dynamic Grid

  - by rkenshin

  Hi, I'm trying to create a dynamic grid using Extjs. The grid is built and displayed when a click event is fired then an ajax request is sent to the server to fetch the columns, records and records definition a.k.a Store Fields. Each node could have different grid structure and that depends on the level of the node in the tree. The only way i came up with so far is function showGrid(response, request) { var jsonData = Ext.util.JSON.decode(response.responseText); var grid = Ext.getCmp('contentGrid'+request.params.owner); if(grid) { grid.destroy(); } var store = new Ext.data.ArrayStore({ id : 'arrayStore', fields : jsonData.recordFields, autoDestroy : true }); grid = new Ext.grid.GridPanel({ defaults: {sortable:true}, id:'contentGrid'+request.params.owner, store: store, columns: jsonData.columns, //width:540, //height:200, loadMask: true }); store.loadData(jsonData.records); if(Ext.getCmp('tab-'+request.params.owner)) { Ext.getCmp('tab-'+request.params.owner).show(); } else { grid.render('grid-div'); Ext.getCmp('card-tabs-panel').add({ id:'tab-'+request.params.owner, title: request.params.text, iconCls:'silk-tab', html:Ext.getDom('grid-div').innerHTML, closable:true }).show(); } } The function above is called when a click event is fired 'click': function(node) { Ext.Ajax.request({ url: 'showCtn', success: function(response, request) { alert('Success'); showGrid(response,request); }, failure: function(results, request) { alert('Error'); }, params: Ext.urlDecode(node.attributes.options); } The problem i'm getting with this code is that a new grid is displayed each time the showGrid function is called. The end user sees the old grids and the new one. To mitigate this problem, I tried destroying the grid and also removing the grid element on each request, and that seems to solve the problem only that records never get displayed this time. if(grid) { grid.destroy(true); } The behavior i'm looking for is to display the result of a grid within a tab and if that tab exists replaced the old grid. Any help is appreciated. Thank you

• jQuery UI autocomplete not working in IE

  - by Peter Di Cecco

  Hi all, I've got the new autocomplete widget in jQuery UI 1.8rc3 working great in Firefox. It doesn't work at all in IE. Can someone help me out? HTML: <input type="text" id="ctrSearch" size="30"> <input type="hidden" id="ctrId"> Javascript: $("#ctrSearch").autocomplete({ source: "ctrSearch.do", minLength: 3, focus: function(event, ui){ $('#ctrSearch').val(ui.item.ctrLastName + ", " + ui.item.ctrFirstName); return false; }, select: function(event, ui){ $('#ctrId').val(ui.item.ctrId); return false; } }); Result (IE 8): The red box is the <ul> element created by jQuery. I also get this error: Line: 116 Error: Invalid argument. When I open it in the IE8 script debugger, it highlights f[b]=d on line 116 of jquery.min.js. Note that I'm using version 1.4.2 of jQuery hosted on Google's servers (https://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js). I've tried removing some of the options, but even when I call .autocomplete() with no options, or with only the source option, I still get the same result. Once again, it's working in Firefox, but not in IE. Any suggestions? Thanks.

• Pagination in Tab Content of Jquery UI

  - by DR.GEWA

  I am making a page with Jquery UI TABS. In one of tabs I want to make pagination for comments. I want such thing. When user clicks on the number of the page, the data of the page , which is linked will load via ajax in the tab. Here is my code <script type="text/javascript"> $(function() { $("#tabs").tabs(); }); $('#demo').tabs({ load: function(event, ui) { $('a', ui.panel).click(function() { $(ui.panel).load(this.href); return false; }); } }); </script> How can I change this , so that any link inside the content with lets say with id "pagination" <a href="/coments?page=12&user_id=12" id="pagination">12</a> ?? Thanks beforehand I tried recently like this even and no luck. This is from http://www.bannerite.com/jquerytest/index2.php Here it work <script type="text/javascript"> $(function() { $("#tabs").tabs(); var hijax = function(panel){ $('a', panel).click(function() { /**makes children 'a' on panel load via ajax, hence hijax*/ $(panel).load(this.href, null, function(){ /**recursively apply the hijax to newly loaded panels*/ hijax(panel); }); /**prevents propagation of click to document*/ return false; }); $('form', panel).css({background: 'yellow'}).ajaxForm({ target: panel, }); }; $('#demo ul').tabs({ /**initialize the tabs hijax pattern*/ load: function(tab, panel) { hijax(panel); } }); }); </script> HEre are the HTML part as Karl gived , but no succes.

• Strings in array are no longer strings after jQuery.each()

  - by Álvaro G. Vicario

  I'm pretty confused with the behaviour of arrays of strings when I loop them through the jQuery.each() method. Apparently, the strings become jQuery objects inside the callback function. However, I cannot use the this.get() method to obtain the original string; doing so triggers a this.get is not a function error message. I suppose the reason is that it's not a DOM node. I can do $(this).get() but it makes my string become an array (from "foo" to ["f", "o", "o"]). How can I cast it back to string? I need to get a variable of String type because I pass it to other functions that compare the values among them. I enclose a self-contained test case (requires Firebug's console): <!DOCTYPE html> <html> <head><title></title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript"><!-- $(function(){ var foo = []; var $foo = $(foo); foo.push("987"); $foo.push("987"); foo.push("654"); $foo.push("654"); $.each(foo, function(i){ console.log("foo[%d]: object=%o; value=%s; string=%o", i, this, this, $(this).get()); // this.get() does not exist }); $foo.each(function(i){ console.log("$foo[%d]: object=%o; value=%s; string=%o", i, this, this, $(this).get()); // this.get() does not exist }); }); //--></script> </head> <body> </body> </html>

• Chart controls for ASP.NET

  - by tolism7

  I am looking people's opinion and experience on using chart controls within an ASP.NET application (web forms or MVC) primarily but also in any kind of project. I am currently doing my research and I have a pretty big list of controls to evaluate. My list includes (in no particular order): ASP.NET controls: DevExpress XtraCharts (http://demos.devexpress.com/XtraChartsDemos/) Dundas Chart for .NET (http://www.dundas.com/) Telerik RadChart for ASP.NET AJAX (http://www.telerik.com/) ComponentArt Charting & Visualization for ASP.NET (http://www.componentart.com/) Infragistics WebChart (http://www.infragistics.com/dotnet/netadvantage/aspnet.aspx#Overview) .net Charting (http://www.dotnetcharting.com/) Chart Control for .Net Framework (Microsoft's) (http://weblogs.asp.net/scottgu/archive/2008/11/24/new-asp-net-charting-control-lt-asp-chart-runat-quot-server-quot-gt.aspx) Flash controls: FusionCharts v3 (http://www.fusioncharts.com/) XML/SWF Charts (http://www.maani.us/xml%5Fcharts/index.php) amCharts (http://www.amcharts.com/) AnyChart (http://www.anychart.com/home/) Javascript: Flot (http://code.google.com/p/flot/) Flotr (http://solutoire.com/flotr/) jqPlot (http://www.jqplot.com/index.php) (If I missed some that worth to be compared against the above please let me know.) What I am looking is opinions on using any of the above so I can form my own and help others do the same, based on what I read here. I do not care which one is better. What I care for is why someone likes one of the above and what do these controls offer as a distinct advantage. I am interested in developer's opinion and I would like to find out which things are difficult doing with any of the above controls and which things are easy to achieve. AJAX compatibility (build in to the controls but also manual), ASP.NET compatibility, input capabilities, data binding options, performance, how much code does one need to write in order to create a chart, are some of the things that I would want to read about. I have already done my research on StackOverflow for relevant questions but there is nothing on the level of detail that I would want to read in order to make a responsible decision.

• Text mining on large database (data mining)

  - by yox

  Hello, I have a large database of resumes (CV), and a certain table skills grouping all users skills. inside that table there's a field skill_text that describes the skill in full text. I'm looking for an algorithm/software/method to extract significant terms/phrases from that table in order to build a new table with standarized skills.. Here are some examples skills extracted from the DB : Sectoral and competitive analysis Business Development (incl. in international settings) Specific structure and road design software - Microstation, Macao, AutoCAD (basic knowledge) Creative work (Photoshop, In-Design, Illustrator) checking and reporting back on campaign progress organising and attending events and exhibitions Development : Aptana Studio, PHP, HTML, CSS, JavaScript, SQL, AJAX Discipline: One to one marketing, E-marketing (SEO & SEA, display, emailing, affiliate program) Mix marketing, Viral Marketing, Social network marketing. The output shoud be something like : Sectoral and competitive analysis Business Development Specific structure and road design software - Macao AutoCAD Photoshop In-Design Illustrator organising events Development Aptana Studio PHP HTML CSS JavaScript SQL AJAX Mix marketing Viral Marketing Social network marketing emailing SEO One to one marketing As you see only skills remains no other representation text. I know this is possible using text mining technics but how to do it ? the database is realy large.. it's a good thing because we can calculate text frequency and decide if it's a real skill or just meaningless text... The big problem is .. how to determin that "blablabla" is a skill ? thanks

• Autocomplete or Select box? (design problem)

  - by Craig Whitley

  I'm working on a comparison website, so needless to say the search function is the primary feature of the site. I have two input text boxes and a search button. At the moment, the input text boxes use Ajax to query the database and show a drop-down box, but I'm wondering if it would be more intuitive to use a select box instead? The second box is dependant on the first, as when the first is selected theres another ajax query so only the available options for the first selection appear in the autocomplete box. Autocomplete Pros: - "Feels" right? - Looks more appealing than a select box (css design)? Cons: - the user has to be instructed on how to use the search (made to think?) - Only really works off the bat with javascript enabled. - The user may get confused if they type in what they want and no box appears (i.e., no results) Select Box Pros: - Can bring up the list of options / know whats there from the outset. - We use select boxes every day (locations etc.) so we're used to how they work. (more intuitive?) Cons: - Can look a little unaesthetic when theres too many options to choose from. I'm thinking maybe at most around 100 options for my site over time. Any thoughts on how I could go about this would be appreciated!

• Parsing XML via jQuery, nested loops

  - by Coughlin

  I am using jQuery to parse XML on my page using $.ajax(). My code block is below and I can get this working to display say each result on the XML file, but I am having trouble because each section can have MORE THAN ONE and im trying to print ALL grades that belong to ONE STUDENT. Here is an example of the XML. <student num="505"> <name gender="male">Al Einstein</name> <course cid="1">60</course> <course cid="2">60</course> <course cid="3">40</course> <course cid="4">55</course> <comments>Lucky if he makes it to lab, hopeless.</comments> </student> Where you see the I am trying to get the results to print the grades for EACH student in each course. Any ideas on what I would do? Thanks, Ryan $.ajax({ type: "GET", url: "final_exam.xml", dataType: "xml", success: function(xml) { var student_list = $('#student-list'); $(xml).find('student').each(function(){ $(xml).find('course').each(function(){ gradeArray = $(this).text(); console.log(gradeArray); }); var name = $(this).find("name").text(); var grade = $(this).find("course").text(); var cid = $(this).find("course").attr("cid"); //console.log(cid); student_list.append("<tr><td>"+name+"</td><td>"+cid+"</td><td>"+grade+"</td></tr>"); }); } });

• Model validation with enumerations

  - by Robert Koritnik

  I'm using DataAnnotations attributes to validate my model objects. My model class looks similar to this: public class MyModel { [Required] public string Title { get; set; } [Required] public List<User> Editors { get; set; } } public class User { public int Id { get; set; } [Required] public string FullName { get; set; } [Required] [DataType(DataType.Email)] public string Email { get; set; } } My controller action looks like: public ActionResult NewItem(MyModel data) { //... } User is presented with a view that has a form with: a text box with dummy name where users enter user's names. For each user they enter, there's a client script coupled with ajax that creates an <input type="hidden" name="data.Editors[0].Id" value="userId" /> for each user entered (enumeration index is therefore not always 0 as written here), so default model binder is able to consume and bind the form without any problems. a text box where users enter the title Since I'm using Asp.net MVC 2 RTM which does model validation instead of input validation I don't know how to avoid validation errors. The thing is I have to use BindAttribute on my controller action. I would have to either provide a white or a black list of properties. It's always a better practice to provide a white list. It's also more future proof. The problem My form works fine, but I get validation errors about user's FullName and Email properties since they are not provided. I also shouldn't feed them to the client (via ajax when user enters user data), because email is personal contact data and is not shared between users. If there was just a single user reference on MyModel I would write [Bind(Include = "Title, Editor.Id")] But I have an enumeration of them. How do I provide Bind white list to work with my model?

• How to refactor this Javascript anonymous function?

  - by HeavyWave

  We have this anonymous function in our code, which is part of the jQuery's Ajax object parameters and which uses some variables from the function it is called from. this.invoke = function(method, data, callback, error, bare) { $.ajax({ success: function(res) { if (!callback) return; var result = ""; if (res != null && res.length != 0) var result = JSON2.parse(res); if (bare) { callback(result); return; } for (var property in result) { callback(result[property]); break; } } }); } I have omitted the extra code, but you get the idea. The code works perfectly fine, but it leaks 4 Kbs on each call in IE, so I want to refactor it to turn the anonymous function into a named one, like this.onSuccess = function(res) { .. }. The problem is that this function uses variables from this.invoke(..), so I cannot just take it outside of its body. How do I correctly refactor this code, so that it does not use anonymous functions and parent function variables?
