  • Do jQuery and JavaScript have different namespaces?

    - by Brett
    I have this code in jQuery.. $(document).ready(function(){ var fieldCounter = 0; ... I have a jQuery function that increments this value. This works, but I can't access this value on the page from a non-jQuery function? The reverse is also true, if I scope it in JavaScript e.g. <script type="text/javascript"> var fieldCounter = 0; I can access it from javascript but jQuery can't view it? I'm probably doing something really dumb?

  • MVC 3 Remote Validation jQuery error on submit

    - by Richard Reddy
    I seem to have a weird issue with remote validation on my project. I am doing a simple validation check on an email field to ensure that it is unique. I've noticed that unless I put the cursor into the textbox and then remove it to trigger the validation at least once before submitting my form I will get a javascript error. e[h] is not a function jquery.min.js line 3 If I try to resubmit the form after the above error is returned everything works as expected. It's almost like the form tried to submit before waiting for the validation to return or something. Am I required to silently fire off a remote validation request on submit before submitting my form? Below is a snapshot of the code I'm using: (I've also tried GET instead of POST but I get the same result). As mentioned above, the code works fine but the form returns a jquery error unless the validation is triggered at least once. Model: public class RegisterModel { [Required] [Remote("DoesUserNameExist", "Account", HttpMethod = "POST", ErrorMessage = "User name taken.")] [Display(Name = "User name")] public string UserName { get; set; } [Required] [Display(Name = "Firstname")] public string Firstname { get; set; } [Display(Name = "Surname")] public string Surname { get; set; } [Required] [Remote("DoesEmailExist", "Account", HttpMethod = "POST", ErrorMessage = "Email taken.", AdditionalFields = "UserName")] [Display(Name = "Email address")] public string Email { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Password")] public string Password { get; set; } [StringLength(100, ErrorMessage = "The {0} must be at least {2} characters long.", MinimumLength = 8)] [DataType(DataType.Password)] [Display(Name = "Confirm password")] public string ConfirmPassword { get; set; } [Display(Name = "Approved?")] public bool IsApproved { get; set; } } public class UserRoleModel { [Display(Name = "Assign Roles")] public IEnumerable<RoleViewModel> AllRoles { get; set; } public RegisterModel RegisterUser { get; set; } } Controller: // POST: /Account/DoesEmailExist // passing in username so that I can ignore the same email address for the same user on edit page [HttpPost] public JsonResult DoesEmailExist([Bind(Prefix = "RegisterUser.Email")]string Email, [Bind(Prefix = "RegisterUser.UserName")]string UserName) { var user = Membership.GetUserNameByEmail(Email); if (!String.IsNullOrEmpty(UserName)) { if (user == UserName) return Json(true); } return Json(user == null); } View: <script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script> <script src="//ajax.googleapis.com/ajax/libs/jqueryui/1.8.17/jquery-ui.min.js" type="text/javascript"></script> <script type="text/javascript" src="/Content/web/js/jquery.unobtrusive-ajax.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.min.js"></script> <script type="text/javascript" src="/Content/web/js/jquery.validate.unobtrusive.min.js"></script> ...... @using (Html.BeginForm()) { @Html.AntiForgeryToken() <div class="titleh"> <h3>Edit a user account</h3> </div> <div class="body"> @Html.HiddenFor(model => model.RegisterUser.UserName) @Html.Partial("_CreateOrEdit", Model) <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(model => model.RegisterUser.IsApproved)</span> @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, true, new { @class = "uniform" }) Active @Html.RadioButtonFor(model => model.RegisterUser.IsApproved, false, new { @class = "uniform" }) Disabled <div class="clear"></div> </div> <div class="button-box"> <input type="submit" name="submit" value="Save" class="st-button"/> @Html.ActionLink("Back to List", "Index", null, new { @class = "st-clear" }) </div> </div> } CreateEdit Partial View @model Project.Domain.Entities.UserRoleModel <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Firstname)</span> @Html.TextBoxFor(m => m.RegisterUser.Firstname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Firstname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Surname)</span> @Html.TextBoxFor(m => m.RegisterUser.Surname, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Surname) <div class="clear"></div> </div> <div class="st-form-line"> <span class="st-labeltext">@Html.LabelFor(m => m.RegisterUser.Email)</span> @Html.TextBoxFor(m => m.RegisterUser.Email, new { @class = "st-forminput", @style = "width:300px" }) @Html.ValidationMessageFor(m => m.RegisterUser.Email) <div class="clear"></div> </div> Thanks, Rich

  • jQuery 1.4.x and the @ symbol

    - by David
    I used to use this script for jquery email obfuscation: $(".replaceAt").replaceWith("@"); $(".obfuscate").each(function () { $(this).attr("href", "mailto:"+$(this).text()); }); <a class="obfuscate">name<span class="replaceAt">-AT-</span>server.com</a> But with jQuery 1.4.x, I now get this error: uncaught exception: Syntax error, unrecognized expression: @ Looking this up on the net, it looks like jQuery thinks that the @ is a special character. I tried to "\@" it and a few other things with not luck. I'm not enough of a jQuery ninja to know how to fix this. Any ideas?

  • Mixing JQuery Ajax with ASP.NET : is there any security risk

    - by Sayem Ahmed
    I am using jQuery with ASP.NET in a project. Instead of using ASP.NET Ajax, I am using jquery's ajax functions. Is there any security risk if I do that? I mean, since I am using jquery's ajax calls, no view state information will be passed to the server so that it can verify the page's authenticity (though it saves a lot of bandwidth..). I would also like to know what is the best/good practice here.

  • update Visual Studio jquery release

    - by rockinthesixstring
    Now that Visual Studio 2010 has jQuery support, I'm wondering how I can update the release version? When you currently create a project, it automatically creates the 1.4.1 files, but there is now the 1.4.2 release on the jQuery.com website. How can I tell VS2010 to use the more recent version of jQuery?

  • Getting elements children with certain tag jQuery

    - by johnnyArt
    I'm trying to get all the input elements from a certain form from jQuery by providing only the name of the form and only knowing that those wanted fields are input elements. Let's say: <form action='#' id='formId'> <input id='name' /> <input id='surname'/> </form> How do I access them individually with jQuery? I tried something like $('#formId > input') with no success, in fact an error came back on the console "XML filter is applied to non-XML value (function (a, b) {return new (c.fn.init)(a, b);})" Maybe I have to do it with .children or something like that? I'm pretty new at jQuery and I'm not really liking the Docs. It was much friendlier in Mootools, or maybe I just need to get used to it. Oh and last but not least, I've seen it asked before but no final answer, can I create a new dom element with jQuery and work with it before inserting it (if I ever do) into de code? In mootools, we had something like var myEl = new Element(element[, properties]); and you could then refer to it in further expressions, but I fail to understand how to do that on jQuery Thanks in advance.

  • jQuery attach function to 'load' event of an element

    - by Miguel Ping
    Hi, I want to attach a function to a jQuery element that fires whenever the element is added to the page. I've tried the following, but it didn't work: var el = jQuery('<h1>HI HI HI</H1>'); el.one('load', function(e) { window.alert('loaded'); }); jQuery('body').append(el); What I really want to do is to guarantee that another jQuery function that is expecting some #id to be at the page don't fail, so I want to call that function whenever my element is loaded in the page. To clarify, I am passing the el element to another library (in this case it's a movie player but it could be anything else) and I want to know when the el element is being added to the page, whether its my movie player code that it is adding the element or anyting else.

  • setting z-index jquery ui controls?

    - by maxp
    Annoyingly, the jquery ui's set a few css properties inline, making it impossible to override them in the stylesheet. I tried to override the values with jquery, but then they get changed back as soon as the control is interacted with. Does anyone know if any of the jquery ui control's initialisers/constructors have the ability to override their z-index value or set other css properties?

  • How does jQuery .data() work?

    - by kazanaki
    My Javascript knowledge is pretty limited. Instead of asking several javascript questions I got the "message" from Stack overflow and started using jQuery right away in order to save me some time. However several times I do not undestand the "magic" behind jQuery and I would love to learn the details. I want to use .data() in my application. The examples are very helpful. I do not understand however WHERE these values are stored. I inspect the webpage with Firebug and as soon as .data() saves an object to a dom element, I do not see any change in Firebug (either HTML or Dom tabs). I tried to look at jQuery source, but it is very advanced for my Javascript knowledge and I lost myself. So the question is: Where do the values stored by jQuery.data() actually go? Can I inspect/locate/list/debug them using a tool?

  • WCF webHttpBinding with jQuery AJAX - removing/working around same origin policy

    - by csauve
    So I'm trying to create a C# WCF REST service that is called by jQuery. I've discovered that jQuery requires that AJAX calls are made under the same origin policy. I have a few questions for how I might proceed. I am already aware of; 1. The hacky solution of JSONP with a server callback 2. The way too much server overhead of having a cross-domain proxy. 3. Using Flash in the browser to make the call and setting up crossdomain.xml at my WCF server root. I'd rather not use these because; 1. I don't want to use JSON, or at least I don't want to be restricted to using it 2. I would like to separate the server that serves static pages from the one that serves application state. 3. Flash in this day in age is out of the question. What I'm thinking: is there anything like Flash's crossdomain.xml file that works for jQuery? Is this "same-origin" policy a part of jQuery or is it a restriction in specific browsers? If it's just a part of jQuery, maybe I'll try digging in the code to work around it.

  • How does jQuery store data with .data()?

    - by TK
    I am a little confused how jQuery stores data with .data() functions. Is this something called expando? Or is this using HTML5 Web Storage although I think this is very unlikely? The documentation says: The .data() method allows us to attach data of any type to DOM elements in a way that is safe from circular references and therefore from memory leaks. As I read about expando, it seems to have a rick of memory leak. Unfortunately my skills are not enough to read and understand jQuery code itself, but I want to know how jQuery stores such data by using data(). http://api.jquery.com/data/

  • jQuery sortColumns plugin: How to sort correctly with rowspan

    - by Thang Pham
    Following this post jQuery table sort (github link: https://github.com/padolsey/jQuery-Plugins/blob/master/sortElements/jquery.sortElements.js), I am successfully sort columns, however it does not work in the case of rowspan: For example, case like this Grape 3,096,671M 1,642,721M Apple 2,602,750M 3,122,020M When I click on the second column, it try to sort Apple 2,602,750M 1,642,721M Grape 3,096,671M 3,122,020M which as you can see is not correct, please any jQuery guru help me fix this problem. Here is my code var inverse = false; function sortColumn(index){ index = index + 1; var table = jQuery('#resultsTable'); table.find('td').filter(function(){ return jQuery(this).index() == index; }).sortElements(function(a, b){ a = convertToNum($(a).text()); b = convertToNum($(b).text()); return ( isNaN(a) || isNaN(b) ? a > b : +a > +b ) ? inverse ? -1 : 1 : inverse ? 1 : -1; },function(){ return this.parentNode; }); inverse = !inverse; } function convertToNum(str){ if(isNaN(str)){ var holder = ""; for(i=0; i<str.length; i++){ if(!isNaN(str.charAt(i))){ holder += str.charAt(i); } } return holder; }else{ return str; } } Question: 1.How do I sort this with rowspan. THE NUMBER OF ROWSPAN IS NOT ALWAYS THE SAME. The above example both Grape and Apple have rowspan of 2, but this is not always the case. 2.Can any explain this syntax: return ( isNaN(a) || isNaN(b) ? a > b : +a > +b ) ? inverse ? -1 : 1 : inverse ? 1 : -1; So I can see that if either a or b is not a number, then do string comparison otherwise do number comparison, but I dont understand the inverse ? -1 : 1 : inverse ? 1 : -1;
