  • Read data from ATOM file with jquery.

    - by carrerasrodrigo
    Hi, i'm trying to read a xml/atom file, the code is: $.ajax({ type: 'GET', url: options.url, data: options.data, dataType: 'xml', async:options.async, success: function(xml) { var feed = new JFeed(xml); if(jQuery.isFunction(options.success)) options.success(feed); } }); The atom file has a field like this: <entry> <content type="xhtml"> <div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div> </content> </entry> The code to read the content tag is: jQuery(this).find('content').eq(0).text(); this - the entry part. The problem is, when jQuery execute this line returns "Docentes y alumnos desa...". There is is a way that jQuery returns---- "<div xmlns="http://www.w3.org/1999/xhtml">Docentes y alumnos desa...</div>" Thanks!! and sorry for the english!!

  • Is MVC 2 client-side validation broken in Visual Studio 2010 RC?

    - by Will
    I can't seem to get client side validation working with the version of MVC released with Visual Studio 2010 RC. I've tried it with two projects -- one upgrade from 1.0, and one using the template that came with VS. I'd think the template version would work, but it doesn't. Added the following scripts: <script type="text/javascript" src="<%= Url.Content("~/Scripts/MicrosoftMvcValidation.js") %>"> </script> <script type="text/javascript" src="<%= Url.Content("~/Scripts/jquery.validate.js")%>"> </script> which are downloaded to the client correctly. Added the following to my form page: <% Html.EnableClientValidation(); %> <%--yes, am aware of the EndForm() bug! --%> <% using (Html.BeginForm()) { %> <%--snip --%> and I can see the client validation scripts have been added to the bottom of the form. But still client validation never happens. What is worse is that in my upgraded project, the client validation scripts are never output in the page! PLEASE NOTE: I am specifically asking about the version of MVC2 that came with VS2010 RC. Also, I do know how to google; please don't waste anybody's time searching and answering if you aren't familiar with this issue in the release candidate of Visual Studio. Thanks.

  • How do I reject if exists? for non-nested attributes?

    - by GoodGets
    Currently my controller lets a user submit muliple "links" at a time. It collects them into an array, creates them for that user, but catches any errors for the User to go back and fix. How can I ignore the creation of any links that already exist for that user? I know that I can use validates_uniqueness_of with a scope for that user, but I'd rather just ignore their creation completely. Here's my controller: @links = params[:links].values.collect{ |link| current_user.links.create(link) }.reject { |p| p.errors.empty? } Each link has a url, so I thought about checking if that link.url already exists for that user, but wasn't really sure how, or where, to do that. Should I tack this onto my controller somehow? Or should it be a new method in the model, like as in a before_validation Callback? (Note: these "links" are not nested, but they do belong_to :user.) So, I'd like to just be able to ignore the creation of these links if possible. Like if a user submits 5 links, but 2 of them already exist for him, then I'd just like for those 2 to be ignored, while the other 3 are created. How should I go about doing this?

  • Updating join fields in an ORM command

    - by Jono
    I have a question about object relational updates on join fields. I am working on a project using codeigniter with datamapper dmz. But I think my problem is with general understanding of ORMs. So fell free to answer with any ORM you know. I have two tables, Goods and Tags. One good can have many tags. Everything is working, but I am looking for a way to merge tags. Meaning I decide I want to remove tag A and instead have everything that is tagged by it, now be tagged by tag B. I only have models for the goods and the tags. There is no separate model for the join relationship, as I believe these ORMs were designed to work. I know how to delete a tag. But I dont know how to reach into the join table to redirect the references since there is no model for the join table. I would rather use the ORM then issuing a raw SQL command.

  • Open PDF Content files in ASP.NET MVC 2

    - by mcbingo
    I want to provide simple href links to my PDF forms that reside in my Forms folder. I have a created a simple Index.aspx and FormController Index action that simple iterates through the list of PDF files using my FormMetaData.xml file. The links get created just fine but when you click on the links I get a 404 exception. That looks like this: Server Error in '/' Application. The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Forms/ccindteamgolfform.pdf Version Information: Microsoft .NET Framework Version:2.0.50727.4927; ASP.NET Version:2.0.50727.4927 This seems like this should open up a new browser window with the PDF in it but perhaps I am making a bad assumption. The PDF content files have Build Action of Content and Copy to Output set to Copy Always. Here is an example output html for the link from my Index.aspx page: <span class="form"> <a href="Forms/ccindteamgolfform.pdf" target="_blank"> <span class="description">Entry Form</span></span> I must be missing something because this does not work. Do I need to add a MapRoute for these documents? Or am I missing something else with the routing? This seems like it should not be that difficult.

  • Retrieving Json via HTML request from Jboss server

    - by Seth Solomon
    I am running into a java.net.SocketException: Unexpected end of file from server when I am trying to query some JSON from my JBoss server. I am hoping someone can spot where I am going wrong. Or does anyone have any suggestions of a better way to pull this JSON from my Jboss server? try{ URL u = new URL("http://localhost:9990/management/subsystem/datasources/data-source/MySQLDS/statistics?read-resource&include-runtime=true&recursive=true"); HttpURLConnection c = (HttpURLConnection) u.openConnection(); String encoded = Base64.encode(("username"+":"+"password").getBytes()); c.setRequestMethod("POST"); c.setRequestProperty("Authorization", "Basic "+encoded); c.setRequestProperty("Content-Type","application/json"); c.setUseCaches(false); c.setAllowUserInteraction(false); c.setConnectTimeout(5000); c.setReadTimeout(5000); c.connect(); int status = c.getResponseCode(); // throws the exception here switch (status) { case 200: case 201: BufferedReader br = new BufferedReader(new InputStreamReader(c.getInputStream())); StringBuilder sb = new StringBuilder(); String line; while ((line = br.readLine()) != null) { sb.append(line+"\n"); } br.close(); System.out.println(sb.toString()); break; default: System.out.println(status); break; } } catch (Exception e) { e.printStackTrace(); }

  • How to return proper 404 for google while providing user friendly content to the user?

    - by Marek
    I am bouncing between posting this here and on Superuser. Please excuse me if you feel this does not belong here. I am observing the behavior described here - Googlebot is requesting random urls on my site, like aecgeqfx.html or sutwjemebk.html. I am sure that I am not linking these urls from anywhere on my site. I suspect this may be google probing how we handle non existent content - to cite from an answer to the linked question: [google is requesting random urls to] see if your site correctly handles non-existent files (by returning a 404 response header) We have a custom page for nonexistent content - a styled page saying "Content not found, if you believe you got here by error, please contact us", with a few internal links, served (naturally) with a 200 OK. The URL is served directly (no redirection to a single url). I am afraid this may discriminate the site at google - they may not interpret the user friendly page as a 404 - not found and may think we are trying to fake something and provide duplicate content. How should I proceed to ensure that google will not think the site is bogus while providing user friendly message to users in case they click on dead links by accident?

  • Background not showing behind floating divs

  • Using Javascript to expand DIVs and go to anchor text

    - by radiantjoy
    I apologize that this question is so similar to "How can you check for a #hash in a URL using JavaScript?" but would appreciate your help with the following. I would like to use Javascript to display text that is a) identified by an anchor. b) contained within 2 collapsed DIVs....ONLY WHEN the anchor is in the URL. Otherwise, the page should display with all DIVs collapsed. Something like this: if (theHashIsABC) { Expand 2 DIVs on the page and go to the anchor; } else { just display the page; } Specifics: 1. Using IE7 2. DIVs ids to be expanded '8589' and '6212' out of several DIVs on the page 3. Anchor name is anchorABC I have been told that it is not possible to expand some DIVs in IE7 so I am thinking I need to expand all DIVs on the page. [ I can expand just the 2 with a link within the page: <a class="jumplink" href="javascript:toggleBlock('6212');toggleBlock('8589')";link to expand DIVs</a> ] This is what I have so far (in head section)... if(window.location.hash = "anchorABC") { //this works with a button on the page that expand all divs function showAll(pstrClass) { var aElts = document.getElementsByTagName('div'); setDisplay(pstrClass, aElts, 'show', 'Block'); aElts = document.getElementsByTagName('span'); setDisplay(pstrClass, aElts, 'show', 'Inline'); //would also like the page to move to the anchor } else { // just display the page } In advance, thank you for your time.

  • How to design Models the correct way: Object-oriented or "Package"-oriented?

    - by ajsie
    I know that in OOP you want every object (from a class) to be a "thing", eg. user, validator etc. I know the basics about MVC, how they different parts interact with each other. However, i wonder if the models in MVC should be designed according to the traditional OOP design, that is to say, should every model be a database/table/row (solution 2)? Or is the intention more like to collect methods that are affecting the same table or a bunch of related tables (solution 1). example for an Address book module in CodeIgniter, where i want be able to "CRUD" a Contact and add/remove it to/from a CRUD-able Contact Group. Models solution 1: bunching all related methods together (not real object, rather a "package") class Contacts extends Model { function create_contact() {) function read_contact() {} function update_contact() {} function delete_contact() {} function add_contact_to_group() {} function delete_contact_from_group() {} function create_group() {} function read_group() {} function update_group() {} function delete_group() {} } Models solution 2: the OOP way (one class per file) class Contact extends Model { private $name = ''; private $id = ''; function create_contact() {) function read_contact() {} function update_contact() {} function delete_contact() {} } class ContactGroup extends Model { private $name = ''; private $id = ''; function add_contact_to_group() {} function delete_contact_from_group() {} function create_group() {} function read_group() {} function update_group() {} function delete_group() {} } i dont know how to think when i want to create the models. and the above examples are my real tasks for creating an Address book. Should i just bunch all functions together in one class. then the class contains different logic (contact and group), so it can not hold properties that are specific for either one of them. the solution 2 works according to the OOP. but i dont know why i should make such a dividing. what would the benefits be to have a Contact object for example. Its surely not a User object, so why should a Contact "live" with its own state (properties and methods). you experienced guys with OOP/MVC, please shed a light on how one should think here in this very concrete task.

  • Configuring IHS server to direct traffic to the Netty component bound to a port

    - by rbot
    I have a Server Component ( based on Jboss-Netty, which could maintain & handle persistent connections ) deployed in WAS. This component when deployed & initiated within the WAS environment, binds to a port & listens for incoming HTTP connection. [ Why i had to deploy a Netty HTTP Server within WAS is another story - management requirement !! Netty is deployed in WAS as a spring bean which when initiated runs on a port in the machine, independent of WAS ] Clients (mobile app) were able to establish persistent HTTP connections (to the above URL::Port) with this netty component & send/receive requests. Now, I have to replicate this feature in our Production Environment where a IHS Server (Web Server) which sits before the WAS. What i expected is to get a IHS URL which could redirect the incoming packets to the specific PORT on WAS, so that the Client apps can establish a similar persistent http connection. Our Server Admin tried a few combinations and we are not able to identify how to proceed further on this. Your expert ideas would be highly appreciated.

  • Resize view on iPhone when rotating

    - by BCBomb47
    I have an application with many views. I want only a couple of the views to be able to rotate to landscape when the device is rotated. I found out that I couldn't use (BOOL)shouldAutorotateToInterfaceOrientation because that would rotate every view in my app. I found a solution to this problem here on Stack Overflow but now I have another issue to deal with. The view rotates when I turn the device but it still shows the view as if it were still in portrait mode (straight up and down). The top and bottom of the view is cut off. Is there a way to have the view rotate and also adjust its size to fit the new orientation? I also found this but wasn't able to get it to work. Here's my code for that view: @implementation businessBank @synthesize webView, activityIndicator; - (void)viewDidLoad { [super viewDidLoad]; NSString *urlAddress = @"website_url"; NSURL *url = [NSURL URLWithString:urlAddress]; NSURLRequest *requestObj = [NSURLRequest requestWithURL:url]; [webView loadRequest:requestObj]; [[UIDevice currentDevice] beginGeneratingDeviceOrientationNotifications]; [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(didRotate:) name:UIDeviceOrientationDidChangeNotification object:nil]; } - (void)didRotate:(NSNotification *)notification { UIDeviceOrientation orientation = [[notification object] orientation]; if (orientation == UIDeviceOrientationLandscapeLeft) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / 2.0)]; } else if (orientation == UIDeviceOrientationLandscapeRight) { [self.view setTransform:CGAffineTransformMakeRotation(M_PI / -2.0)]; } else if (orientation == UIDeviceOrientationPortraitUpsideDown) { [self.view setTransform:CGAffine TransformMakeRotation(M_PI)]; } else if (orientation == UIDeviceOrientationPortrait) { [self.view setTransform:CGAffineTransformMakeRotation(0.0)]; } }

  • Trouble getting $.ajax() to work in PhoneGap against a locally hosted server

    - by David Gutierrez
    Currently trying to make an ajax post request to an IIS Express hosted MVC 4 Web API end point from an android VM (Bluestacks) on my machine. Here are the snippets of code that I am trying, and cannot get to work: $.ajax({ type: "POST", url: "http://10.0.2.2:28434/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); Whenever I run this request I always get back a textStatus of 'error'. After hours of trying different things, I pushed my End Point to an actual server, and was able to actually get responses back in PhoneGap if I built up an XMLHttpRequest by hand, like so: var request = new XMLHttpRequest(); request.open("POST", "http://172.16.100.42/MobileRewards/api/devices", true); request.onreadystatechange = function(){//Call a function when the state changes. console.log("state = " + request.readyState); console.log("status = " + request.status); if (request.readyState == 4) { if (request.status == 200 || request.status == 0) { console.log("*" + request.responseText + "*"); } } } request.send("{EncryptedPassword:1234,UserName:test,DeviceToken:d234}"); Unfortunately, if I try to use $.ajax() against the same end point in the snippet above I still get a status text that says 'error', here is that snippet for reference: $.ajax({ type: "POST", url: "http://172.16.100.42/MobileRewards/api/devices", data: {'EncryptedPassword':'1234','UserName':'test','DeviceToken':'d234'} }).always(function( data, textStatus, jqXHR ) { alert( textStatus ); }); So really, there are a couple of questions here. 1) Why can't I get any ajax calls (post or get) to successfully hit my End Point when it's hosted via IIS Express on the same machine that the Android VM is running? 2) When my end point is hosted on an actual server, through IIS and served through port 80, why can't I get post requests to be successful when I use jquery's ajax calls? (Even though I can get it to work by manually creating an XMLHttpRequest) Thanks

  • Saving HttpResponse/Request to file system

    - by chrisjlong
    Here is my scenario. User fills out this large page which is dynamically created based off DB values. Those values can change. When the user fills out the page and hits submit we want to save a copy of the page as html on the server, this way if the text or wording changes, when they go back to view their posted information, it is historically accurate. So I basically need to do this protected void buttonSave_Click(object sender, EventArgs e) { //collect information into an object to save it in the db bool result = BusinessLogic.Save(myBusinessObject); if (result) //!!! Here is where I need to save this page as an html file on my servers IFS!!!! else //whatever Response.Redirect("~/SomeOtherPage.aspx"); } Any help is greatly apprciated. Also I CANNOT just request the data from the url because query string parameters are a big no no in this case. The key to pull the database info up (at its highest level) is all in session so I cant just request a url and save it. Thanks!

    I am making a POST to another php file that I want to render in the browser. so clearly, using jquery POST wont work, since it works through AJAX. echo '<div class="showcase_URL"><a class="purl" name="'.$row->num.'" href="#">PROJECT URL</a></div>'; what I have till now in javascript is: $(".showcase_URL a").click(function() { //alert($(this).attr("name")); var number = $(this).attr("name"); $.post( "app-display.php", {app: number}, function(data){ top.location.href = 'app-display.php'; }); }); what I have in app-display.php: $query = 'SELECT num, title, thumb_url, url, type, cat, dated, details FROM app WHERE `num` = "$_POST[app]"'; but it is currently giving me a page without the contents of app-display.php. all the other fragments of the page are loading: header, footer etc. the PHP Response (in Firebug) I am getting is the normal html of the page. how should i do it?

I need some more definite answers here: has anybody succeed using git through Windows proxies? Which version? Thanks.

  • Establishing persistent connection to a database in Java

    - by gmile
    I've ran through several examples over the web, and found that every single time I need something from the DB, I should write the following code: try { // Step 1: Load the JDBC driver. Class.forName("mysql_driver_name"); // Step 2: Establish the connection to the database. String url = "jdbc:string_to_mysql_server"; Connection conn = DriverManager.getConnection(url,"user1","password"); // fetch from the DB ... } catch (Exception e) { System.err.println("Got an exception! "); System.err.println(e.getMessage()); } It's very annoying to put up this code every time I want something from the DB, so the question is - is there a way to only once connect entirely all my app to the DB somehow at the very start point, avoiding copy-pasting mentioned code, and then be able to do everything I want with DB? I've quickly looked through NetBeans's Project menu, but didn't find any clue on how to configurate a persistent connection to a selected DB. If it's important, i'm writing a purely desktop app, i.e. using Java EE. Also, it's worth mentioning that I'm a kinda beginner in Java.

    I am trying to move the nav text (home...) up in the middle to the right. But when I do -120px for the top (nav.li), it eats up part of the banner. How can I fix that? Thanks body { background-color: #D6E2FF; } #headerimg { margin: 10px 0px 0px 0px; height: fixed; width: 95%; } #header { height:auto; background:url("menubar.jpg") no-repeat; } #logo { background: transparent url("logo.jpg") no-repeat; display: block; width: 146px; height: 146px; border: none; } #navcontainer { font-size: 200%; margin: -100px 0px 0px 500px; } #navlist li { display: inline; list-style-type: none; padding-right: 30px; color: #FFFFFF; }

  • Extensionless URLs in IIS 6

    - by Jason Marsell
    My client has asked me to build a personalized URL system so that they can send out really short URLs in postcards to customers like this: www.client.com/JasonSmith03 www.client.com/TonyAdams With these URLs, I need IIS 6 to trap the incoming request and pass that “JasonSmith03” token to my database to determine which landing page to redirect them to. I’d love to use an HttpHandler or HttpModule but they both look like they require an file extension (.aspx) in the URL. Wildcard mapping will chew up every incoming request and that’s ridiculous. ISAPI filters are just text routing files, so I can’t employ logic to call the database. According to Scott Guthrie, this would be cake if I had IIS 7, but I don’t. Can this be done using MVC? I’ve been working with MVP for the last few years, so I haven’t done any MVC and routing. I thought I remembered that MVC has the ability to use REST-style extensionless URLs. I’d be more than happy to have these personalized URLs land on a site that’s built in MVC, if it will work. Thank you!

  • Dynamic checkboxlist

    - by Steve
    Hi, I am currently building a dynamic url tab system that user can say what urls they want to be displayed on a tabpage control. In the database i have the following columns. userID, int URLName var Enabled bit I am pulling the data back ok but what i am trying do is populate a checkbox list with the urlname and its status on a user options page so they can say what tabs they want displayed. I have wrote the following methods to get the urls and create the checkboxes however i keep getting the following error. ex = {"InvalidArgument=Value of '1' is not valid for 'index'.\r\nParameter name: index"} It reads the first row ok but when it hits the 2nd row that is being returned i get that error. Has anyone got any ideas? Thanks private void GetUserURLS() { db.initiateCommand("[Settings].[LoadAllUserURLS]", CommandType.StoredProcedure); sqlp = db.addParameter("@UserID", _UserID, SqlDbType.Int, ParameterDirection.Input); sqlp = db.addParameter("@spErrorID", DBNull.Value, SqlDbType.Int, ParameterDirection.InputOutput); db.executeCommand(); CreateCheckBoxes(db.getTable(0).Rows); db.releaseCommand(); } private void CreateCheckBoxes(DataRowCollection rows) { try { int i = 0; foreach (DataRow row in rows) { //Gets the url name and path when the status is enabled. The status of Enabled / Disabled is setup in the users option page string URLName = row["URLName"].ToString(); bool enabled = Convert.ToBoolean(row["Enabled"]); CheckedListBox CB = new CheckedListBox(); CB.Items.Insert(i, URLName); CB.Tag = "CB" + i.ToString(); checkedListBox1.Items.Add(CB); i++; } } catch (Exception ex) { //Log error Functionality func = new Functionality(); func.LogError(ex); //Error message the user will see string FriendlyError = "There has been populating checkboxes with the urls - A notification has been sent to development"; Classes.ShowMessageBox.MsgBox(FriendlyError, "There has been an Error", MessageBoxButtons.OK, MessageBoxIcon.Error); } }
