  • OnSubmit does work right in the Validation plugin in jQuery

    - by novellino
    Hello, I an quite new to jQuery and I have a problem while trying to create a form. I am using the Validation plugin for validate the email (one the form's field). When I click the Submit button I want to call my own function because I want to save the data in an XML file. This is my button: (as I understood the plugin uses "submit" for understand the button) <input type="submit" name="submit" class="submit" id="submit_btn" value="Send"/> and here is the script for the validation: <script type="text/javascript"> $(document).ready(function() { //this is my form $("#contactForm").validate(); /*save the valid data in the xml*/ $(".submit").click(function() { var email = $("input#email").val(); var subject = $("input#subject").val(); var message = $("textarea#message").val(); if (email == "" || !$("#contactForm").valid()) { return false; } var dataString = 'email='+ email + '&subject=' + subject + '&message=' + message; //alert("DATA: " +dataString); $.ajax({ type: "POST", url: "SaveData.jsp", data: dataString, success: function(data){} }); return false; }); }); In general it works ok but I have two basic problems. When I click the button in the beginning having all the form empty, I get no message for the field required. Also when the data are valid and I am doing the submit, the form does not become clear after the submit. If I deleted this script code, these actions are working properly but I can not save the data! Does anyone know what is wrong? Thanks a lot!

  • why doesn't IE8 refresh textbox right away?(Jquery)

    - by AndrewSmith
    I have 3 radio buttons and one textbox in my page. These 3 radio controls represent corresponding choice and among them, the third one enables textbox that is disabled by default. If user clicks any one from the first twos after clicking the third, the textbox will be emptied(if user input any) and disabled again. The problem is, in IE, the textbox isn't emptied not until I click back once again on the said textbox. I've used jquery val methods as well as attr but nothing seems to work. You can see my code as follows. The very same code works just fine in Mozilla. I'm not sure why IE is having problem. m.bind_eventform = function(){ $('input[name=poster]').change(function(){ if($('input[name=poster]:checked').val()==2) $('#poster_other').removeAttr('disabled'); else if(!($('#poster_other').is(':disabled'))) { $('#poster_other').attr('disabled','disabled'); $('#poster_other').attr('value',''); //this one doesn't work $('#poster_other').val(''); //as well as this one } }); }; $(document).ready(m.bind_eventform);

  • JAX-RS --- How to return JSON and HTTP Status code together?

    - by masato-san
    I'm writing REST web app (Netbean6.9, JAX-RS, Toplink-essential) and trying to return JSON and Http status code. I have code ready and working just to return JSON when HTTP GET Method is called from client. Code snippet @Path("get/id") @GET @Produces("application/json") public M_?? getMachineToUpdate(@PathParam("id") String id) { //some code to return JSON . . return myJson But I also want to return HTTP status code (500, 200, 204 etc) along with returning JSON. I tried using HttpServletResponse object, response.sendError("error message", 500); But this made browser to think it's real 500 so output web page was regular Http 500 error page. What I want to is just to return status code so that my Javascript on client side can handle some logic depending on what HTTP status code is returned. (maybe just to display the error code and message on html page.) Is it possible to do so? or should HTTP status code not be used for such thing?

  • cycle through spans on jquery click, removing the first-child

    - by jacob
    Basically, this advances to the next hidden span when clicked. The markup: <div id="facts"> <span>click to cycle</span> <span>fact 1</span> <span>fact 2</span> <span>fact 3</span> <span>fact 4</span> </div> The js: $(document).ready(function() { var current = 1; $('#facts span').click(function() { // Hide all of them $('#facts span').hide(); // Unhide the current one: $('#facts span:eq(' + (current % $('#facts span').length) + ')').show(); // Increment the variable console.log(current % 4); current++; }); // Unhide the first one on load $('#facts span:first-child').show(); });? What I'm trying to do now is remove the first span after it's been clicked, because it is not necessary for the user to see the 'click to cycle' instruction again.

  • VB6 Game Development

    - by CVS-2600Hertz-wordpress-com
    Hi All, I am developing a game in VB6 (plz don't ask me why :) ). The storyboard is ready and a rough implementation is underway. I am following a "pure-software-rendering" approach. (i.e. no DirectX, no openGL etc.) Amongst many others, the following "serious" problems exist: 2D alpha transparency reqd. to implement overlays. Parallax implementation to give depth-of-field illusion. Capturing mouse-scroll events globally (as in FPS-es; mapping them to changing weapon). Async sound play with absolute "near-zero-lag". Any ideas anyone. Please suggest any well documented library/ocx or sample-code. Plz do suggest solutions with good performance and as little overhead as possible. Also, anyone who has developed any games, and would be open to sharing her/his code would be highly appreciated. (any well-acknowledged VB games whose source-code i can study??) UPDATE: Here is a screen shot of GearHead Garage. This picture ought to describe what i was attempting in words above... :) Thank You

  • How to configure a subproject dependency in Maven without deploying jars?

    - by MikeHoss
    I googled this and it seems that no one has an answer, yet it seems like such an elementary thing that it should be possible. I have the following project structure: parent ---sub-project1 ---sub-project2 sub-project2 needs to have sub-project1 as a dependency. So I have this in sub-project2's pom: <dependencies> <dependency> <artifactId>sub-project1</artifactId> <groupId>mygroup</groupId> <version>1.0-SNAPSHOT</version> </dependency> .... When I do this, Maven tries to dowload the sub-project1.jar file, which does not exist because it's not ready for the repo yet. I tried to put a <scope>import</scope> in the dependency, but that didn't work either -- same result. So what do I have to do to get Maven to look at sub-project1 when building sub-project2?

  • How to return ArrayList results from an IntentService

    - by gcl1
    I have an IntentService that loads up an ArrayList with data from a network source (AWS SDB tables). The ArrayList is in a global space -- accessible to both the calling Activity and the IntentService (like this: appState = ((App)getApplicationContext())). When the IntentService is done, it notifies the Activity through a ResultReceiver, and the Activity calls adapter.notifyDataChanged() to update the ListView. This solution works most of the time, ... but it violates the rule that only the UI thread should make changes to data underlying a ListView. So as it is, I sometimes get an error: "The content of the adapter has changed but ListView did not receive a notification." I think this must be a common situation. Please let me know if you have any suggestions or best practices for this problem. Here are three options I'm aware of: Keep the IntentService, and have it store the results in another "working" ArrayList, also in the global space. When the result is ready, the IntentService calls the ResultReceiver (on the UI thread), which can then: a) copy the result to the ArrayList associated with the ListView, and b) call adapter.notifyDataChanged(). CONS: I don't like the idea of putting temp/working data in a global space, and copying the result list seems inefficient. Keep the IntentService, and have it pass the results back through a bundle loaded with a ParcelableArrayList. CONS: I'm not sure if this approach would scale for very large result sets. It also requires copying the result list. Switch to a Service which builds a local copy of the result list. Have the Activity directly access the address space of the Service in order to read the result list. CON: Still requires copying results to the ArrayList associated with the ListView. Thank you.

  • Function in JS returns undefined

    - by megapool020
    Hello there, I have the following problem. The alert allways returns undefined, but I know it has a value. What am I doing wrong. I'm out of solutions... I'm using JQUERY jquery-1.4.2.min.js Tnx in advance $(document).ready(function(){ $('#generateButton').click(createIBAN); }); function createIBAN(){ //---- First check if a bank has been selected, //---- if not, then show error if($('#selectBank').val()==''){ alert('Selecte a bank!'); }else{ var bankAccount = generateBankAccount(); alert(bankAccount); } return false; } function generateBankAccount(){ //---- Create "elfproef" bankaccount var bankAccount = ''; //---- Set the amount of digits in a bankaccount digitAmount = 9; //---- Make random digitstring for (var i = 0; i < digitAmount; i++) { bankAccount += Math.floor(Math.random() * digitAmount); } //---- validate the string, if not "elf-proef" if (elfProef(bankAccount)==false) { //---- regenerate the string generateBankAccount(); }else{ return bankAccount; } } function elfProef(bankAccount) { //---- set sum to 0 and start the for-loop for counting var sum = 0; for (var i = 0; i < digitAmount; i++) { //---- for every digit multiply it times 9 - number //---- of the digit and count it to the sum var sum += bankAccount.charAt(i) * (digitAmount - i); } //---- Check if sum can be devided by 11 without having ##,## if(sum % 11==0){ //---- return true means string is "elf-proef" return true; }else { //---- String is not "elf-proef", try again return false; } }

  • Is A Web App Feasible For A Heavy Use Data Entry System?

    - by Rob
    Looking for opinions on this, we're working on a project that is essentially a data entry system for a production line. Heavy data input by users who normally work in Excel or other thick client data systems. We've been told (as a consequence) that we have to develop this as a thick client using .NET. Our argument was to develop as a web app, as it resolves a lot of issues and would be easier to write and maintain. Their argument against the web is that (supposedly) the web is not ready yet for a heavy duty data entry system, and that the web in a browser does not offer the speed, responsiveness, and fluid experience for the end-user that a thick client can (citing things such as drag and drop, rapid auto-entry and data navigation, etc.) Personally, I think that with good form design and JQuery/AJAX, a web app could do everything a thick client does just as well, and they just don't know what they're talking about. The irony is that a thick client has to go to a lot more effort to manage the deployment and connectivity back to the central data server than a web app would need to do, so in terms of speed I would expect a web app to be faster. What are the thoughts of those out there? Are there any technologies currently in production use that modern data entry systems are being developed as web apps in? Appreciate any feedback. Regards, Rob.

  • jQuery Accordian

    - by Fuego DeBassi
    Just wondering if anyone can provide some basic advice on an accordion I'm trying to simplify. Got a working version, but it seems way overly complex. Here is my new JS. $(document).ready(function() { $("#themes li ul").hide(); $("#themes li").hover(function() { $("ul").show(); }, function() { $("li ul").hide(); }); The markup looks like this: <ul> <li>Tier 1 <ul> <li>Tier 2</li> <li>Tier 2</li> </ul> </li> <li>Tier 1 <ul> <li>Tier 2</li> <li>Tier 2</li> </ul> </li> </ul> My script works alright. But it shows all of the child ul's when any parent li is hovered, and it hide's all the child ul's when unhovered. Just not sure how I can get it to A.) Only .show the li ul when that specific li is hovered. And B.) Hide the show'n li ul only when another one is hovered (not itself). Example + explanation would be especially helpful! Thanks!!

  • Retreive value stored in array with jquery index

    - by Dustin
    I am trying to retreive the stored value (div id) of an index stored in var "current" when it's div is clicked, so I can use it in a function to iterate through to the next index later. I want to store this stored value in a var so I can use it in a div show/hide function. my html is quite simple: <div class="gallerypreview" id="1"></div> <div class="gallerypreview" id="2"></div> <div class="gallerypreview" id="3"></div> my javascript is something like this: var images = new Array(); $(document).ready( function(){ $('.gallerypreview').each(function() { images.push($(this).attr("id")); }); $('.gallerypreview').click(function() { var current = $('.gallerypreview').index(this); }); }); how would I go about retrieving the div id from this clicked div? nothing I have tried has worked. I can get the index # fine, but I cannot find the value of the index using any functions that utilize the index # yet.

  • Change css when tab has active class

    - by Yunowork
    I'm trying to change the background colour of the <body> depending on what tab specific is active. When a tab is active, a class called 'st_view_active' is added onto the tab content. In the tab content I add a hidden div with the hex code of what my body background colour should be when that tab is active, my jQuery code looks like this: $(document).ready(function() { $(function(){ $('body').css('backgroundColor',$('.st_view_active').find('.background').text()); }); }); And my html code when the tab is active is following: <div class="tab-6 st_view st_view_active" > <div style="display:none" class="background">yellow</div> <div class="st_view_inner"> tab 6 </div> </div> So when tab6 is active the background of the body should be yellow. However, this is not working, the background colour is not changing, what am I doing wrong here? DEMO and JSfiddle Thanks PS: The red and blue square is the next and previous tab handler..

  • iPhone: Does it ever make sense for an object to retain its delegate?

    - by randombits
    According to the rules of memory management in a non garbage collected world, one is not supposed to retain a the calling object in a delegate. Scenario goes like this: I have a class that inherits from UITableViewController and contains a search bar. I run expensive search operations in a secondary thread. This is all done with an NSOperationQueue and subclasses NSOperation instances. I pass the controller as a delegate that adheres to a callback protocol into the NSOperation. There are edge cases when the application crashes because once an item is selected from the UITableViewController, I dismiss it and thus its retain count goes to 0 and dealloc gets invoked on it. The delegate didn't get to send its message in time as the results are being passed at about the same time the dealloc happens. Should I design this differently? Should I call retain on my controller from the delegate to ensure it exists until the NSOperation itself is dealloc'd? Will this cause a memory leak? Right now if I put a retain on the controller, the crashes goes away. I don't want to leak memory though and need to understand if there are cases where retaining the delegate makes sense. Just to recap. UITableViewController creates an NSOperationQueue and NSOperation that gets embedded into the queue. The UITableViewController passes itself as a delegate to NSOperation. NSOperation calls a method on UITableViewController when it's ready. If I retain the UITableViewController, I guarantee it's there, but I'm not sure if I'm leaking memory. If I only use an assign property, edge cases occur where the UITableViewController gets dealloc'd and objc_msgSend() gets called on an object that doesn't exist in memory and a crash is imminent.

  • OSMF seek with Amazon Cloudfront

    - by giorrrgio
    I've written a little OSMF player that streams via RTMP from Amazon Cloudfront. There's a known issue, the mp3 duration is not correctly readed from metadata and thus the seek function is not working. I know there's a workaround implying the use of getStreamLength function of NetConnection, which I successfully implemented in a previous non-OSMF player, but now I don't know how and when to call it, in terms of OSMF Events and Traits. This code is not working: protected function initApp():void { //the pointer to the media var resource:URLResource = new URLResource( STREAMING_PATH ); // Create a mediafactory instance mediaFactory = new DefaultMediaFactory(); //creates and sets the MediaElement (generic) with a resource and path element = mediaFactory.createMediaElement( resource ); var loadTrait:NetStreamLoadTrait = element.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; loadTrait.addEventListener(LoaderEvent.LOAD_STATE_CHANGE, _onLoaded); player = new MediaPlayer( element ); //Marker 5: Add MediaPlayer listeners for media size and current time change player.addEventListener( DisplayObjectEvent.MEDIA_SIZE_CHANGE, _onSizeChange ); player.addEventListener( TimeEvent.CURRENT_TIME_CHANGE, _onProgress ); initControlBar(); } private function onGetStreamLength(result:Object):void { Alert.show("The stream length is " + result + " seconds"); duration = Number(result); } private function _onLoaded(e:LoaderEvent):void { if (e.newState == LoadState.READY) { var loadTrait:NetStreamLoadTrait = player.media.getTrait(MediaTraitType.LOAD) as NetStreamLoadTrait; if (loadTrait && loadTrait.netStream) { var responder:Responder = new Responder(onGetStreamLength); loadTrait.connection.call("getStreamLength", responder, STREAMING_PATH); } } }

  • Change HTML image into a Button for partial refresh of page

    - by user990951
    I am new to webpage design and MVC. I have a aspx page and I have a html image. I want to change this image and make it clickable so that it will refresh only the bottom half of the page when clicked. I setup my image so that the source of the image is updated by the controller. By using the following src="<%=ViewData["BookImg"] %>" So that the whole story is clear. When a person clicks on the image of the book, it displays on the bottom half of the page information about that book pulled from a sql database. I am thinking that I would need to look into getting ajax implemented so that I can do partial page update. But the question is how do I change that HTML image into a button. Thanks in advance. ---updating per the answer chosen but still having problems--- home.aspx <% Html.RenderPartial("HomePartialView"); %> <img id = "Book_Img" src="<%=ViewData["BookImg"] %>" alt = "click Me" class="imgClick"/> <script src="../../Scripts/jquery-1.5.1.js" type="text/javascript"> $(document).ready(function(){ $(".imgClick").click(function () { $("HomePartialView").load("../../Controllers/HomeController/PartialViewBook"); }); }); </script> ---Controller public ActionResult PartialViewBook() { ViewData[imageBookPressd] = "hello world"; return View("HomePartialView"); }

  • jQuery - Unchecking checkboxes that act like radio buttons

    - by Cecil
    Hey All, I have the following jQuery code to make my checkboxes act like radio buttons, so that only 1 of the 3 can be checked at a time. <script type="text/javascript" language="javascript"> $(document).ready(function() { $("#testing input:checkbox").change(function(){ var checkname = $(this).attr("name"); $("input:checkbox[name='" + checkname + "']").removeAttr("checked"); this.checked = true; }); }); </script> The checkboxes are layed out like the following: <input type="checkbox" id="testing" name="testing" value="B"> <input type="checkbox" id="testing" name="testing" value="I"> <input type="checkbox" id="testing" name="testing" value="A"> This works exactly how i want it to work, not a problem, except once i click one of the 3, i cant unclick it so that none of them are checked, this is what i want to happen, so along with being only able to click one at a time, im able to uncheck them completely. Any help would be grand :)

  • IE "Microsoft JScript runtime error: Object expected"

    - by Stephen Borg
    Hi there, I have problems with regards to javascript only when using IE. The error I am getting is "Microsoft JScript runtime error: Object expected" and I have no idea why. It is then jumping into the JQuery 1.4.2 file, without giving me a proper error message. All I am doing is simply reading on page load the raw URL, and getting a query string named Search. Using that in an AJAX call to return products and put then into a DIV. No biggies, but somehow IE is managing to blow my page up :-( Any ideas? Code as follows : <script type="text/javascript"> $(document).ready(function (e) { $('.boxLoader').show(); function getParameterByName(name) { name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); var regexS = "[\\?&]" + name + "=([^&#]*)"; var regex = new RegExp(regexS); var results = regex.exec(window.location.href); if (results == null) return ""; else return decodeURIComponent(results[1].replace(/\+/g, " ")); } var Search; Search = getParameterByName("search"); $('#searchCriteria').text(Search); $.get("/Handlers/processProducts.aspx", { SearchCriteria: Search }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); $('#searchBox').live("click", function () { $.get("/Handlers/processProducts.aspx", { SearchCriteria: $('#searchCriteria').val() }, function (data) { $('#innercontent').html(data); $('#innercontent').fadeIn(200); $('.boxLoader').fadeOut(200); }); }); }); </script>

  • Object Design: How to Organize/Structure a "Collection Class"

    - by CrimsonX
    I'm currently struggling to understand how I should organize/structure a class which I have already created. The class does the following: As its input in the constructor, it takes a collection of logs In the constructor it validates and filters the logs through a series of algorithms implementing my business logic After all filtering and validation is complete, it returns a collection (a List) of the valid and filtered logs which can be presented to the user graphically in a UI. Here is some simplified code describing what I'm doing: class FilteredCollection { public FilteredCollection( SpecialArray<MyLog> myLog) { // validate inputs // filter and validate logs in collection // in end, FilteredLogs is ready for access } Public List<MyLog> FilteredLogs{ get; private set;} } However, in order to access this collection, I have to do the following: var filteredCollection = new FilteredCollection( secialArrayInput ); //Example of accessing data filteredCollection.FilteredLogs[5].MyLogData; Other key pieces of input: I foresee only one of these filtered collections existing in the application (therefore should I make it a static class? Or perhaps a singleton?) Testability and flexibility in creation of the object is important (Perhaps therefore I should keep this an instanced class for testability?) I'd prefer to simplify the dereferencing of the logs if at all possible, as the actual variable names are quite long and it takes some 60-80 characters to just get to the actual data. My attempt in keeping this class simple is that the only purpose of the class is to create this collection of validated data. I know that there may be no "perfect" solution here, but I'm really trying to improve my skills with this design and I would greatly appreciate advice to do that. Thanks in advance.

  • What do you do when your boss doesn't care about code quality?

    - by Chad Johnson
    My boss (a proprietor) is a developer like me. He comes, however, from a C background and severely lacks knowledge of the benefits of proper object-oriented design. That, or he simply ignores them. So my co-worker developed this feature prototype in a week, and it's not release-ready--at least not from a good code standpoint. It works; it does the job--but it'sa freaking prototype. It's totally not scalable. My boss wants to wow clients and "just get the feature out." I understand that. But, we could take two weeks and finish this shit up, or we could take three and finish this shit up AND do it so that it's scalable. I just KNOW we are going to want to add onto this feature in the coming months, and then, a customer is going to "need it in a week," and so even though we've agreed to refactor when we want to add onto the feature, IT WILL NEVER HAPPEN! This ALWAYS happens. I'm the code quality assurance guy, but my boss seems to see me as a radical and thinks I just waste time, whereas I actually am trying to follow good, known solid design patterns. He just wants his stinking feature though, and he doesn't want to spend the time or money to do things well. He pretty much listens to what I have to say, and then he ultimately just makes the decision to take the shortest path (which cuts corners a lot). I often develop large, important features for our software. THOSE THINGS TAKE TIME! They're not happy with the time it's taken with past projects, though, but the features I've put in all work really damn well and are very scalable. How do you all deal with this kind of situation?

  • Binding mousemove within mousedown function with jQuery

    - by colinjameswebb
    I am trying to bind a mousemove event to a div when the left mousebutton is down, and unbind when it is released. This code should be fairly self-explainatory. function handleMouseDown(e, sbar){ if (e.button == 0){ console.log(sbar); //firebug sbar.bind('mousemove', function(event){ handleMouseMove(event, sbar); }); } } function handleMouseUp(e, sbar){ sbar.unbind('mousemove'); } function handleMouseMove(e, sbar){ // not sure it this will work yet, but unimportant $(".position").html(e.pageX); } $(document).ready(function (){ var statusbar = $(".statusbar"); statusbar.mousedown(function(event){ handleMouseDown(event, this); }); statusbar.mouseup(function(event){ handleMouseUp(event, this); }); }); The important part of the HTML looks like this <div id="main"> <div class="statusbar"> <p class="position"></p> </div> </div> Firebug says that the bind methods are undefined on the variable sbar within handleMouseDown and handleMouseUp. The firebug console prints out <div class="statusbar"> for the line commented //firebug. I'm doing something wrong, probably when binding the mousedown and mouseup... but what?! I'm using jQuery v1.4.2, if that helps?
