  • Jquery live() vs delegate()

    - by PeeHaa
    I've read some posts here and on the web about the differences of live() and delegate(). However I haven't found the answer I'm looking for (if this is a dupe please tell me). I know the difference between live and delegate is that live can not be used in a chain. As I also read somewhere delegate is in some case faster (better performance). So I am wondering is there a situation where you would use live instead of delegate?

  • jQuery see if next element (not sibling) exists

    - by DevlshOne
    Here's my HTML code: <select class="grid_3 required jobData valid" id="clli" name="clli" style="font-size: 10px; border: none;"> <option value="0">Select One...</option> <option value="905"></option> <option value="931">0</option> <option value="1">ABRDMSES</option> </select> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <img alt="This data has been changed!" title="This data has been changed!" src="images/caution.png"> <select class="grid_3 required jobData" id="job_status" name="job_status" style="font-size: 10px; border: none;"> <option value="0">Select One...</option> </select> When a $('#clli').change(); occurs, I slap a caution image next to it to warn the user that there are changes to be saved. However, if they make more than one change to the same element, I first want to see if there is already a caution image there before sending a new one. Any theories/methods on how to just scope out the next (but not $.next()) element?

  • How to get jquery to append output immediately after each ajax call in a loop

    - by david_nash
    I'd like to append to an element and have it update immediately. console.log() shows the data as expected but append() does nothing until the for loop has finished and then writes it all at once. index.html: ... <body> <p>Page loaded.</p> <p>Data:</p> <div id="Data"></div> </body> test.js: $(document).ready(function() { for( var i=0; i<5; i++ ) { $.ajax({ async: false, url: 'server.php', success: function(r) { console.log(r); //this works $('#Data').append(r); //this happens all at once } }); } }); server.php: <?php sleep(1); echo time()."<br />"; ?> The page doesn't even render until after the for loop is complete. Shouldn't it at least render the HTML first before running the javascript?

  • animate each child jquery

    - by Martavis P.
    It's amazing how simple this should be but I can't get it to work. I'm looking to animate a set of divs one at a time. I am using animate.css for those familiar with it. I thought I may have found the answer here but jsFiddle is not working at the moment. Anywho, the code is $('.elements').each(function(i) { $(this).addClass('animated slideInLeft').delay(500); }); The problem is that when I debug and step through each element, the animation is happening for each element but when I let it run, it appears to all do it at once. What is needed to actually show the animation one at a time? Thanks EDIT: jsFiddle is back up and that link provided below did not help. The answer did not include looping through elements, but looping the animation itself. EDIT 2 Here is a Fiddle to play with if you guys need one.

  • ASP.Net MVC 2 Auto Complete Textbox With Custom View Model Attribute & EditorTemplate

    - by SeanMcAlinden
    In this post I’m going to show how to create a generic, ajax driven Auto Complete text box using the new MVC 2 Templates and the jQuery UI library. The template will be automatically displayed when a property is decorated with a custom attribute within the view model. The AutoComplete text box in action will look like the following:   The first thing to do is to do is visit my previous blog post to put the custom model metadata provider in place, this is necessary when using custom attributes on the view model. http://weblogs.asp.net/seanmcalinden/archive/2010/06/11/custom-asp-net-mvc-2-modelmetadataprovider-for-using-custom-view-model-attributes.aspx Once this is in place, make sure you visit the jQuery UI and download the latest stable release – in this example I’m using version 1.8.2. You can download it here. Add the jQuery scripts and css theme to your project and add references to them in your master page. Should look something like the following: Site.Master <head runat="server">     <title><asp:ContentPlaceHolder ID="TitleContent" runat="server" /></title>     <link href="../../Content/Site.css" rel="stylesheet" type="text/css" />     <link href="../../css/ui-lightness/jquery-ui-1.8.2.custom.css" rel="stylesheet" type="text/css" />     <script src="../../Scripts/jquery-1.4.2.min.js" type="text/javascript"></script>     <script src="../../Scripts/jquery-ui-1.8.2.custom.min.js" type="text/javascript"></script> </head> Once this is place we can get started. Creating the AutoComplete Custom Attribute The auto complete attribute will derive from the abstract MetadataAttribute created in my previous post. It will look like the following: AutoCompleteAttribute using System.Collections.Generic; using System.Web.Mvc; using System.Web.Routing; namespace Mvc2Templates.Attributes {     public class AutoCompleteAttribute : MetadataAttribute     {         public RouteValueDictionary RouteValueDictionary;         public AutoCompleteAttribute(string controller, string action, string parameterName)         {             this.RouteValueDictionary = new RouteValueDictionary();             this.RouteValueDictionary.Add("Controller", controller);             this.RouteValueDictionary.Add("Action", action);             this.RouteValueDictionary.Add(parameterName, string.Empty);         }         public override void Process(ModelMetadata modelMetaData)         {             modelMetaData.AdditionalValues.Add("AutoCompleteUrlData", this.RouteValueDictionary);             modelMetaData.TemplateHint = "AutoComplete";         }     } } As you can see, the constructor takes in strings for the controller, action and parameter name. The parameter name will be used for passing the search text within the auto complete text box. The constructor then creates a new RouteValueDictionary which we will use later to construct the url for getting the auto complete results via ajax. The main interesting method is the method override called Process. With the process method, the route value dictionary is added to the modelMetaData AdditionalValues collection. The TemplateHint is also set to AutoComplete, this means that when the view model is parsed for display, the MVC 2 framework will look for a view user control template called AutoComplete, if it finds one, it uses that template to display the property. The View Model To show you how the attribute will look, this is the view model I have used in my example which can be downloaded at the end of this post. View Model using System.ComponentModel; using Mvc2Templates.Attributes; namespace Mvc2Templates.Models {     public class TemplateDemoViewModel     {         [AutoComplete("Home", "AutoCompleteResult", "searchText")]         [DisplayName("European Country Search")]         public string SearchText { get; set; }     } } As you can see, the auto complete attribute is called with the controller name, action name and the name of the action parameter that the search text will be passed into. The AutoComplete Template Now all of this is in place, it’s time to create the AutoComplete template. Create a ViewUserControl called AutoComplete.ascx at the following location within your application – Views/Shared/EditorTemplates/AutoComplete.ascx Add the following code: AutoComplete.ascx <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <%     var propertyName = ViewData.ModelMetadata.PropertyName;     var propertyValue = ViewData.ModelMetadata.Model;     var id = Guid.NewGuid().ToString();     RouteValueDictionary urlData =         (RouteValueDictionary)ViewData.ModelMetadata.AdditionalValues.Where(x => x.Key == "AutoCompleteUrlData").Single().Value;     var url = Mvc2Templates.Views.Shared.Helpers.RouteHelper.GetUrl(this.ViewContext.RequestContext, urlData); %> <input type="text" name="<%= propertyName %>" value="<%= propertyValue %>" id="<%= id %>" class="autoComplete" /> <script type="text/javascript">     $(function () {         $("#<%= id %>").autocomplete({             source: function (request, response) {                 $.ajax({                     url: "<%= url %>" + request.term,                     dataType: "json",                     success: function (data) {                         response(data);                     }                 });             },             minLength: 2         });     }); </script> There is a lot going on in here but when you break it down it’s quite simple. Firstly, the property name and property value are retrieved through the model meta data. These are required to ensure that the text box input has the correct name and data to allow for model binding. If you look at line 14 you can see them being used in the text box input creation. The interesting bit is on line 8 and 9, this is the code to retrieve the route value dictionary we added into the model metada via the custom attribute. Line 11 is used to create the url, in order to do this I created a quick helper class which looks like the code below titled RouteHelper. The last bit of script is the code to initialise the jQuery UI AutoComplete control with the correct url for calling back to our controller action. RouteHelper using System.Web.Mvc; using System.Web.Routing; namespace Mvc2Templates.Views.Shared.Helpers {     public static class RouteHelper     {         const string Controller = "Controller";         const string Action = "Action";         const string ReplaceFormatString = "REPLACE{0}";         public static string GetUrl(RequestContext requestContext, RouteValueDictionary routeValueDictionary)         {             RouteValueDictionary urlData = new RouteValueDictionary();             UrlHelper urlHelper = new UrlHelper(requestContext);                          int i = 0;             foreach(var item in routeValueDictionary)             {                 if (item.Value == string.Empty)                 {                     i++;                     urlData.Add(item.Key, string.Format(ReplaceFormatString, i.ToString()));                 }                 else                 {                     urlData.Add(item.Key, item.Value);                 }             }             var url = urlHelper.RouteUrl(urlData);             for (int index = 1; index <= i; index++)             {                 url = url.Replace(string.Format(ReplaceFormatString, index.ToString()), string.Empty);             }             return url;         }     } } See it in action All you need to do to see it in action is pass a view model from your controller with the new AutoComplete attribute attached and call the following within your view: <%= this.Html.EditorForModel() %> NOTE: The jQuery UI auto complete control expects a JSON string returned from your controller action method… as you can’t use the JsonResult to perform GET requests, use a normal action result, convert your data into json and return it as a string via a ContentResult. If you download the solution it will be very clear how to handle the controller and action for this demo. The full source code for this post can be downloaded here. It has been developed using MVC 2 and Visual Studio 2010. As always, I hope this has been interesting/useful. Kind Regards, Sean McAlinden.

  • Application Event Log keeps getting corrupted

    - by yakatz
    I recently asked about repairing a corrupt event log, because it seemed to be a one-off event. The event log has since exhibited the same behavior 3 times. We have been trying to find patterns, but so far we have found nothing. The server runs several ASP.NET applications and three scheduled tasks written in .NET. The last modified date of the event log once happened to be the same time as one of the scheduled tasks, but the others have not been. Any suggestions of where to look next or a way we can get any information out of a corrupt evtx file? The server is running critical e-commerce applications, so we want to keep the number of restarts required to a minimum. Edit: I ran DUMPEL and got very strange results. 1/9/2012 4:14:05 PM 1 100 1000 Application Error N/A SERVERNAME Faulting application name: w3wp.exe, version: 7.5.7601.17514, time stamp: 0x4ce7a5f8

  • ASP.NET MVC Validation Complete

    - by Ricardo Peres
    OK, so let’s talk about validation. Most people are probably familiar with the out of the box validation attributes that MVC knows about, from the System.ComponentModel.DataAnnotations namespace, such as EnumDataTypeAttribute, RequiredAttribute, StringLengthAttribute, RangeAttribute, RegularExpressionAttribute and CompareAttribute from the System.Web.Mvc namespace. All of these validators inherit from ValidationAttribute and perform server as well as client-side validation. In order to use them, you must include the JavaScript files MicrosoftMvcValidation.js, jquery.validate.js or jquery.validate.unobtrusive.js, depending on whether you want to use Microsoft’s own library or jQuery. No significant difference exists, but jQuery is more extensible. You can also create your own attribute by inheriting from ValidationAttribute, but, if you want to have client-side behavior, you must also implement IClientValidatable (all of the out of the box validation attributes implement it) and supply your own JavaScript validation function that mimics its server-side counterpart. Of course, you must reference the JavaScript file where the declaration function is. Let’s see an example, validating even numbers. First, the validation attribute: 1: [Serializable] 2: [AttributeUsage(AttributeTargets.Property, AllowMultiple = false, Inherited = true)] 3: public class IsEvenAttribute : ValidationAttribute, IClientValidatable 4: { 5: protected override ValidationResult IsValid(Object value, ValidationContext validationContext) 6: { 7: Int32 v = Convert.ToInt32(value); 8:  9: if (v % 2 == 0) 10: { 11: return (ValidationResult.Success); 12: } 13: else 14: { 15: return (new ValidationResult("Value is not even")); 16: } 17: } 18:  19: #region IClientValidatable Members 20:  21: public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context) 22: { 23: yield return (new ModelClientValidationRule() { ValidationType = "iseven", ErrorMessage = "Value is not even" }); 24: } 25:  26: #endregion 27: } The iseven validation function is declared like this in JavaScript, using jQuery validation: 1: jQuery.validator.addMethod('iseven', function (value, element, params) 2: { 3: return (true); 4: return ((parseInt(value) % 2) == 0); 5: }); 6:  7: jQuery.validator.unobtrusive.adapters.add('iseven', [], function (options) 8: { 9: options.rules['iseven'] = options.params; 10: options.messages['iseven'] = options.message; 11: }); Do keep in mind that this is a simple example, for example, we are not using parameters, which may be required for some more advanced scenarios. As a side note, if you implement a custom validator that also requires a JavaScript function, you’ll probably want them together. One way to achieve this is by including the JavaScript file as an embedded resource on the same assembly where the custom attribute is declared. You do this by having its Build Action set as Embedded Resource inside Visual Studio: Then you have to declare an attribute at assembly level, perhaps in the AssemblyInfo.cs file: 1: [assembly: WebResource("SomeNamespace.IsEven.js", "text/javascript")] In your views, if you want to include a JavaScript file from an embedded resource you can use this code: 1: public static class UrlExtensions 2: { 3: private static readonly MethodInfo getResourceUrlMethod = typeof(AssemblyResourceLoader).GetMethod("GetWebResourceUrlInternal", BindingFlags.NonPublic | BindingFlags.Static); 4:  5: public static IHtmlString Resource<TType>(this UrlHelper url, String resourceName) 6: { 7: return (Resource(url, typeof(TType).Assembly.FullName, resourceName)); 8: } 9:  10: public static IHtmlString Resource(this UrlHelper url, String assemblyName, String resourceName) 11: { 12: String resourceUrl = getResourceUrlMethod.Invoke(null, new Object[] { Assembly.Load(assemblyName), resourceName, false, false, null }).ToString(); 13: return (new HtmlString(resourceUrl)); 14: } 15: } And on the view: 1: <script src="<%: this.Url.Resource("SomeAssembly", "SomeNamespace.IsEven.js") %>" type="text/javascript"></script> Then there’s the CustomValidationAttribute. It allows externalizing your validation logic to another class, so you have to tell which type and method to use. The method can be static as well as instance, if it is instance, the class cannot be abstract and must have a public parameterless constructor. It can be applied to a property as well as a class. It does not, however, support client-side validation. Let’s see an example declaration: 1: [CustomValidation(typeof(ProductValidator), "OnValidateName")] 2: public String Name 3: { 4: get; 5: set; 6: } The validation method needs this signature: 1: public static ValidationResult OnValidateName(String name) 2: { 3: if ((String.IsNullOrWhiteSpace(name) == false) && (name.Length <= 50)) 4: { 5: return (ValidationResult.Success); 6: } 7: else 8: { 9: return (new ValidationResult(String.Format("The name has an invalid value: {0}", name), new String[] { "Name" })); 10: } 11: } Note that it can be either static or instance and it must return a ValidationResult-derived class. ValidationResult.Success is null, so any non-null value is considered a validation error. The single method argument must match the property type to which the attribute is attached to or the class, in case it is applied to a class: 1: [CustomValidation(typeof(ProductValidator), "OnValidateProduct")] 2: public class Product 3: { 4: } The signature must thus be: 1: public static ValidationResult OnValidateProduct(Product product) 2: { 3: } Continuing with attribute-based validation, another possibility is RemoteAttribute. This allows specifying a controller and an action method just for performing the validation of a property or set of properties. This works in a client-side AJAX way and it can be very useful. Let’s see an example, starting with the attribute declaration and proceeding to the action method implementation: 1: [Remote("Validate", "Validation")] 2: public String Username 3: { 4: get; 5: set; 6: } The controller action method must contain an argument that can be bound to the property: 1: public ActionResult Validate(String username) 2: { 3: return (this.Json(true, JsonRequestBehavior.AllowGet)); 4: } If in your result JSON object you include a string instead of the true value, it will consider it as an error, and the validation will fail. This string will be displayed as the error message, if you have included it in your view. You can also use the remote validation approach for validating your entire entity, by including all of its properties as included fields in the attribute and having an action method that receives an entity instead of a single property: 1: [Remote("Validate", "Validation", AdditionalFields = "Price")] 2: public String Name 3: { 4: get; 5: set; 6: } 7:  8: public Decimal Price 9: { 10: get; 11: set; 12: } The action method will then be: 1: public ActionResult Validate(Product product) 2: { 3: return (this.Json("Product is not valid", JsonRequestBehavior.AllowGet)); 4: } Only the property to which the attribute is applied and the additional properties referenced by the AdditionalFields will be populated in the entity instance received by the validation method. The same rule previously stated applies, if you return anything other than true, it will be used as the validation error message for the entity. The remote validation is triggered automatically, but you can also call it explicitly. In the next example, I am causing the full entity validation, see the call to serialize(): 1: function validate() 2: { 3: var form = $('form'); 4: var data = form.serialize(); 5: var url = '<%: this.Url.Action("Validation", "Validate") %>'; 6:  7: var result = $.ajax 8: ( 9: { 10: type: 'POST', 11: url: url, 12: data: data, 13: async: false 14: } 15: ).responseText; 16:  17: if (result) 18: { 19: //error 20: } 21: } Finally, by implementing IValidatableObject, you can implement your validation logic on the object itself, that is, you make it self-validatable. This will only work server-side, that is, the ModelState.IsValid property will be set to false on the controller’s action method if the validation in unsuccessful. Let’s see how to implement it: 1: public class Product : IValidatableObject 2: { 3: public String Name 4: { 5: get; 6: set; 7: } 8:  9: public Decimal Price 10: { 11: get; 12: set; 13: } 14:  15: #region IValidatableObject Members 16: 17: public IEnumerable<ValidationResult> Validate(ValidationContext validationContext) 18: { 19: if ((String.IsNullOrWhiteSpace(this.Name) == true) || (this.Name.Length > 50)) 20: { 21: yield return (new ValidationResult(String.Format("The name has an invalid value: {0}", this.Name), new String[] { "Name" })); 22: } 23: 24: if ((this.Price <= 0) || (this.Price > 100)) 25: { 26: yield return (new ValidationResult(String.Format("The price has an invalid value: {0}", this.Price), new String[] { "Price" })); 27: } 28: } 29: 30: #endregion 31: } The errors returned will be matched against the model properties through the MemberNames property of the ValidationResult class and will be displayed in their proper labels, if present on the view. On the controller action method you can check for model validity by looking at ModelState.IsValid and you can get actual error messages and related properties by examining all of the entries in the ModelState dictionary: 1: Dictionary<String, String> errors = new Dictionary<String, String>(); 2:  3: foreach (KeyValuePair<String, ModelState> keyValue in this.ModelState) 4: { 5: String key = keyValue.Key; 6: ModelState modelState = keyValue.Value; 7:  8: foreach (ModelError error in modelState.Errors) 9: { 10: errors[key] = error.ErrorMessage; 11: } 12: } And these are the ways to perform date validation in ASP.NET MVC. Don’t forget to use them!

  • jQuery event handlers always execute in order they were bound - any way around this?

    - by asgeo1
    It can be anoying that jQuery event handlers always execute in the order they were bound. For example: $('span').click(doStuff1()); $('span').click(doStuff2()); clicking on the span will cause doStuff1() to fire, followed by doStuff2(). At the time I bind doStuff2(), I would like the option to bind it before doStuff1(), but there doesn't appear to be any easy way to do this. I suppose most people would say, just write the code like this: $('span').click(function (){ doStuff2(); doStuff1(); }); But this is just a simple example - in practise it is not always convienient to do that. There are situations when you want to bind an event, and the object you are binding to already has events. And in this case you may simply want the new event to fire before any other existing events. So what is the best way to achieve this in jQuery?

  • Subscribe to the 'complete' event of a .load() on a specific DOM element?

    - by DustMason
    Hi all, I already use both .live() and .bind('ajaxComplete') to accomplish certain related tasks, but I have found myself wanting to be able to listen for the 'complete' event of a specific DOM element which will call jQuery's .load() at various times. In this situation I don't want to listen for ALL complete events globally (unless someone can show me how to get the proper target from the event object returned by 'ajaxComplete'). I would like to be able to do something like this: $('.selector').load('url.php',{data:data},function(){ ... }); and then somewhere else, attach a handler to listen and execute some other code whenever that ajax call fires and completes: $('.selector').bind('complete',function(){ ... }); is there any way to do this? or must i always make use of the 'complete' event within the context of the load() method?

  • SQLAuthority News – First SQL Bangalore Event Report – Nov 24, 2012 – SQL Server User Group Bangalore

    - by pinaldave
    A very common question I often receive - Do we have SQL Server User Group in Bangalore? Yes! SQL Bangalore – we had very first meeting on Nov 24, 2012 and very soon we are going to have another User Group meeting. The goal is to keep up a monthly rhythm of User Group meeting. If you are in Bangalore area please join the Facebook page and you will keep on getting regular update about SQL Server. In the very first meeting we have five 30 minute session and had a fantastic time. We had the best of the best speakers presenting all the five sessions. The event was inaugurated by Vinod Kumar M by presenting on T-SQL Pitfalls. His excellent and eye-opening session was followed by Manas Dash. He enlightened everybody with functions introduced in SQL Server 2012. We had a surprise guest from Mumbai – Raj Chaodhary. If you know him he has a very interesting way to present sessions and he presented on SQL Joins. His hard to follow act was followed by Sudeepta who presented on Contained Database. This subject is quite entertaining and interesting. My session was last in order and I was eagerly waiting to present. I had decided to do something new this time so I had created around 52 slides and two demos. I was committed to go over all the 52 slides and both of the demos in 25 minutes of the time. I had interesting story as well. Though, I was a bit nervous I was able to go over a complete slide deck and demo in 25 minutes of the time I had. We also were very fortunate to have international guest Lynn Langit from USA present at the event as well. She presented an overview of the Big Data in very little time – something not everyone can do it efficiently. We are very thankful to our sponsor Pluralsight for awarding USD 300 worth Annual Subscription. It was the most awaited moment of the day. Well, overall we had a great fun with 100+ attendees learning SQL Server.

  • Travelling MVP #3: Community event in Varna, Bulgaria

    - by DigiMortal
    Second stop in my DevReach 2012 trip was at Varna. We had not much time to hang around there but this problem will get fixed next year if not before. But still we had sessions there with Dimitar Georgijev and I had also chance to meet local techies. Next time we will have more tech and beers for sure! We started in the morning from Bucharest and travelled through Ruse, Razgrad and Shumen to Varna. It’s about 275km. We used cab, local bus and Dimitar father’s car. We had one food stop in Ruse and after that we went directly to Varna. Here is our route on map. Varna is Bulgarian city that locates on western coast of Black Sea. I have been there once before this trip and it’s good place to have vacation under sun. Also autumn is there milder than here in Estonia (third day of snow is going on). Bulgaria has some good beers, my favorite mankind killer called rakia and very good national cuisine. Food is made of fresh stuff and it is damn good experience. Here are some arbitrarily selected images (you can click on these to view at original size): Old bus “monument” in Razgrad Stuffed peppers, Bulgarian national cuisine Infra-red community having good time and beers We made our sessions at one study class of Varna technical university. It’s a little bit old style university but everything we needed was there and we had no problems with machinery. Sessions were same as in Bucharest. The user group in Varna is brand new and hopefully it will be something bigger one good day. At least I try to make my commits so they get on their feet quicker. As we had not much time to announce the event there was about 15 guys listening to us and I’m happy that it was not too much hyped event because still I was getting my first experiences with foreign audiences. After sessions we took our stuff to hotel and went to hang around with local techies. We had some good time there and made some new friends. Next time when I go to Varna I go back as more experienced speaker and I plan to do there one tougher and highly challenging session. Maybe somebody from Estonian community will join me and then it will be well planned surprise-attack to Varna :)
