  • How do I toggle two images using jQuery and radio buttons?

    - by trench
    This isn't pretty, but I think you'll get what I'm trying to do. <label><input name="jpgSel" type="radio" value="0">jpg 1</label><br /> <label><input name="jpgSel" type="radio" value="1">jpg 2</label><br /> <div id="showjpg"></div> and $(document).ready(function() { $("select").change(function () { if ($("jpgSel:checked").val() == 1) { $('#showjpg').attr({ src: 'one.jpg', alt: 'one dot jpg' }); } else { $('#showjpg').attr({ src: 'two.jpg', alt: 'two dot jpg' }); } });

  • Extract data from uint8 to double

    - by HADJ AMOR HASSEN
    I have a C function receiving a uint8 pointer with another parameter which is its size (number of bytes). I want to extract double data from this buffer. Here is my code: Write(uint8* data, uint8 size) /* data and size are given by a callback to my function)*/ { double d; for (i = 0; i < size; i++) { d = ((double*)&data)[i]; printf(" d = %d\n"); } } The problem is that I am not receiving what I am sending within an external hardware. I guess that my cast is wrong. I tried other methods but without any good result. I am still not able to get what I send.

  • single sign on in asp.net

    - by gopal
    Hi , We have developed implemented single sign on methodology to authenticate user. When a page is requested, if it is not authenticated then a login page will be redirected. Once they logged in the requested page will be shown. this is working when we don't assign a domain to the virtual directory. But when we assign the domain to virtual directory after the authentication the application is not redirecting to the requested page. We are using FormsAuthentication.GetRedirectUrl method to redirect the requested page. Why this is happening? How can we resolve this issue?

  • Converting json data to an HTML table

    - by dnaluz
    I have an array of data in php and I need to display this data in a HTML table. Here is what an example data set looks like. Array( Array ( [comparisonFeatureId] => 1182 [comparisonFeatureType] => Category [comparisonValues] => Array ( [0] => Not Available [1] => Standard [2] => Not Available [3] => Not Available ) [featureDescription] => Rear Seat Heat Ducts ),) The dataset is a comparison of 3 items (shown in the comparisonValues index of the array) In the end I need the row to look similar to this <tr class="alt2 section_1"> <td><strong>$record['featureDescription']</strong></td> <td>$record['comparisonValues'][0]</td> <td>$record['comparisonValues'][1]</td> <td>$record['comparisonValues'][2]</td> <td>$record['comparisonValues'][3]</td> </tr> The problem I am coming across is how to best do this. Should I create the entire table HTML on the server side pass it over an ajax call and just dump pre-rendered HTML data into a div or pass the json data and render the table client side. Any elegant suggestions? Thanks in advanced.

  • Is it possible to authenticate on another website?

    - by Blankman
    If I am on a website#1, and I enter my username/pwd for website#2 on a login page that is on website#1, and website#1, behind the scenes, makes a httpwebrequest to website#2 and posts to the login page. If I then navigate to website#2, should I be logged in? website#2 uses formsauthentication and I call a httpHandler that is on website#2 and pass it the username/password via the querystring. Should this work?

  • Using Remote Web Page to Initialize iPhone App

    - by Chris_K
    My iPhone app relies on a vendor's XML feed to provide data. But that feed is not locked down. The vendor could change the format of the XML at any time, although so far they've promised not to. Since I might want to tell my app to use a different URL for its data source, I'd like to set up a single "Command Central" Web page, on my own server, to direct the app to the correct data source. In other words, each time my app starts, in the background and unseen by the user, it would visit "http://www.myserver.com/iphoneapp_data_sources.xml" to retrieve the URL for retrieving data from my vendor. That way, if my vendor suddenly changes the exact URL or the XML feed that the app needs, I can update that Web page and ensure that all installations of the app are using the correct XML feed. Does anyone have any advice or examples showing this kind of approach? It seems as if this must be a common problem, but so far I haven't found a well-established design pattern that fits it.

  • is it possible to store server returned json data in jqgrid to display columnnames models data dynamically for every request?

    - by user1768246
    is it possible to store server returned json data in jqgrid to display columnnames models data dynamically for every request ? $("#grid").jqGrid({ type: "GET", url: "", var columnNames = $("#grid")[0].p.colNames, var columnModel = $("#grid")[0].p.colNames, var columnData = $("#grid")[0].p.colNames, datatype: 'jsonstring', datastr: columnData, colModel: columnModel, jsonReader: { root: 'innerWrapper.rows', page: "result.gridData.outerWrapper.page", total: "result.gridData.outerWrapper.total", records: "result.gridData.outerWrapper.total", repeatitems: false, }, gridview: true, pager: "pager", height: "auto", rowNum: 10, width:"auto", height:"auto", rowList: [10, 20, 30,40], viewrecords: true, caption:"Graph Data", rownumbers: true, });

  • ASP.NET MVC Access model data in masterpage

    - by Paul
    I have created a UserSiteBaseController that gets commonly used data and sets the data to a UserSiteBaseViewData viewmodel in a method called SetViewData public T CreateViewData<T>() where T : UserSiteBaseViewData, new() { .... } I then create specific Controllers that inherit from the UserSiteBaseController as well as viewModels that inherit from UserSiteHomeViewData and can be created in the controller like so: public ActionResult Index(string slug) { Slug = slug; var viewData = CreateUserSiteHomeViewData<UserSiteHomeViewData>(); //If invalid slug - throw 404 not found if (viewData == null) return PageNotFound(); viewData.Announcements = _announcementsData.All(slug).ToList(); return View(viewData); } private T CreateUserSiteHomeViewData<T>() where T : UserSiteHomeViewData, new() { T viewData = CreateViewData<T>(); return viewData; } The UserBaseViewData holds data that needs to be use on every page so it would be great to be able to access this data from the Masterpage in a strongly typed manner. Is this possible or am I going about this in the incorrect manner?

  • Rails - Update a single attribute : link with custom action or form with hidden fields?

    - by MrRuru
    Let's say I have a User model, with a facebook_uid field corresponding to the user's facebook id. I want to allow the user to unlink his facebook account. Do do so, I need to set this attribute to nil. I currently see 2 ways of doing this First way : create a custom action and link to it # app/controllers/users_controller.rb def unlink_facebook_account @user = User.find params[:id] # Authorization checks go here @user.facebook_uid = nil @user.save # Redirection go here end # config/routes.rb ressources :users do get 'unlink_fb', :on => :member, :as => unlink_fb end # in a view = link_to "Unlink your facebook account", unlink_fb_path(@user) Second way : create a form to the existing update action # app/views/user/_unlink_fb_form.html.haml = form_for @user, :method => "post" do |f| = f.hidden_field :facebook_uid, :value => nil = f.submit "Unlink Facebook account" I'm not a big fan of either way. In the first one, I have to add a new action for something that the update controller already can do. In the second one, I cannot set the facebook_uid to nil without customizing the update action, and I cannot have a link instead of a button without adding some javascript. Still, what would you recommend as the best and most elegant solution for this context? Did I miss a third alternative?

  • form validation with jquery and livevalidation

    - by ImpY
    I'm trying to do some form validation with livevaldation & jquery. I've a formular with an input field like that: <div id="prenameDiv" class="control-group"> `<input id="prename" name="prename" class="input-large" placeholder="Max" >` </div> So if there's an error on validation 'livevalidaton' adds the class 'LV_invalid_field' to the input - it looks like that: <div id="prenameDiv" class="control-group"> <input id="prename" name="prename" class="input-large LV_invalid_field" placeholder="Max" > </div> That's ok, but now I'll add another class 'error' to the div 'prenameDiv' when the DOM changes that it looks like that: <div id="prenameDiv" class="control-group error"> `<input id="prename" name="prename" class="input-large LV_invalid_field" placeholder="Max" ` </div> I tried it that way: if ($("#prenameDiv").bind("DOMSubtreeModified")){ `if ($("#prename").hasClass("LV_invalid_field")) {` $("#prenameDiv").addClass("error"); } } But nothing changes? Do you have some ideas?

    Trying to set a select dropdown with a slider. You move the jquery ui slider and then it will change the selection of the other two dropdowns. is there a current method in jquery that would set these options? Current dropdown: <select id="alert-options-frequency-opts"> <option value=""></option> <option value="1">1</option> <option value="2">2</option> <option value="3">3</option> <option value="4">4</option> <option value="5">5</option> <option value="6">6</option> <option value="7">7</option> <option value="8">8</option> <option value="9">9</option> <option value="10">10</option> </select>

  • Referencing ASP.net textbox data in JavaScripts

    - by GoldenEarring
    I'm interested in making an interactive 3D pie chart using JavaScript and ASP.net controls for a webpage. Essentially, I want to make an interactive version of the chart here: https://google-developers.appspot.com/chart/interactive/docs/gallery/piechart#3D I want to have 5 ASP.net textboxes where the user enters data and then submits it, and the chart adjusts according to what the user enters.

  • Javascript: Perform function on form submit

    - by flight643
    Hopefully this is a pretty simple question! I've got the code working in jQuery to listen for a specific form on a page to be submitted and perform an alert when it is.. I.e.: The form itself doesn't have a name so I am targetting the form within a specific form ID. $("#content form").submit(function() { alert("lorem ipsum dolor?"); }); What would be the syntax for performing this in javascript alone without using jquery? For example, I have this code (below) and just am unsure of how to listen for the form to be submitted to perform an action.. var submitform = document.getElementById("content").getElementsByTagName("form"); Thanks!

  • Using javascript, show a certain amount of divs based on an answer

    - by Adam
    I'm building a form that first asks if you have 'foo'. If the answer is 'Yes', a div appears and asks 'How many foo do you have'? Based on the quantity answered, I'd like to show only that many divs. Thus if the user answers 1, only the first div will show. If they answer three, the first three will show. I have it set so that if the user answers no, the question of the amount remains hidden, but if they answer yes, they would be prompted for the quantity. This is what I've got so far... <script type="text/javascript"> $(document).ready(function(){ $(window).load(function() { $('#amt_of_foo,.foo_panels').hide(); }); $('#yes_foo').click(function() { $('#amt_of_foo').show(); }); $('#no_foo').click(function() { $('.foo_panels,#amt_of_foo').hide(); }); }); </script> </head> <body> <ul> <li> <div class="panel section_panel"> <h2>Questions About Your Foo</h2> <span>Do you have foo?:</span> <input type="radio" name="foo" id="no_foo" /> No <br /> <input type="radio" name="foo" id="yes_foo" /> Yes:</span></span> <span id="amt_of_foo"> <span>How many foo do you have?:</span> <span><input id="qty_of_foo" type="text" size="5" /> </span> </span> </div> </li> <!--answered yes to foo, and entered amount--> <div class="foo_panels"> <li> <li> <div class="panel foo_1"> <h1>First foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> <li> <div class="panel foo_2"> <h1>Second foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> <li> <div class="panel foo_3"> <h1>Third foo's information</h1> <span>Foo name:&nbsp;<input type="text" size="20" /></span> </div> </li> </div> <!--answered no to foo--> <li> <div class="panel"> <h1>Next Question, if no foo</h1> </div> </li> </ul> The ul is used for a jQuery 'slider' plugin. the 'panel' class is used for global css.

  • Stop an input field in a form from being submitted

    - by Acorn
    I'm writing some javascript that will insert some input fields into a form on a website. The thing is, I don't want those input fields to affect the form in any way, I don't want them to be submitted when the form is submitted, I only want my javascript to have access to their values. Is there some way I could add some input fields into the middle of a form and not have them submitted when the form is submitted? Obviously the ideal thing would be for the input fields to not be in the form element, but I want the layout of my resulting page to have my inserted input fields appear between elements of the original form.
