  • Dojox Datagrid contains data, but shows up as empty

    - by Vivek
    I'd really appreciate any help on this. There is this Dojox Datagrid that I'm creating programatically and supplying JSON data. As of now, I'm creating this data within JavaScript itself. Please refer to the below code sample. var upgradeStageStructure =[{ cells:[ { field: "stage", name: "Stage", width: "50%", styles: 'text-align: left;' }, { field:"status", name: "Status", width: "50%", styles: 'text-align: left;' } ] }]; var upgradeStageData = [ {id:1, stage: "Preparation", status: "Complete"}, {id:2, stage: "Formatting", status: "Complete"}, {id:3, stage: "OS Installation", status: "Complete"}, {id:4, stage: "OS Post-Installation", status: "In Progress"}, {id:5, stage: "Application Installation", status: "Not Started"}, {id:6, stage: "Application Post-Installation", status: "Not Started"} ]; var stagestore = new dojo.data.ItemFileReadStore({data:{identifier:"id", items: upgradeStageData}}); var upgradeStatusGrid = new dojox.grid.DataGrid({ autoHeight: true, style: "width:400px;padding:0em;margin:0em;", store: stagestore, clientSort: false, rowSelector: '20px', structure: upgradeStageStructure, columnReordering: false, selectable: false, singleClickEdit: false, selectionMode: 'none', loadingMessage: 'Loading Upgrade Stages', noDataMessage:'There is no data', errorMessage: 'Failed to load Upgrade Status' }); dojo.byId('progressIndicator').innerHTML=''; dojo.byId('progressIndicator').appendChild(upgradeStatusGrid.domNode); upgradeStatusGrid.startup(); The problem is that I am not seeing anything within the grid upon display (no headers, no data). But I know for sure that the data in the grid does exist and the grid is properly initialized, because I called alert (grid.domNode.innerHTML);. The resultant HTML that is thrown up does show a table containing header rows and the above data. This link contains an image which illustrates what I'm seeing when I display the page. (Can't post images since my account is new here) As you may notice, there are 6 rows for 6 pieces of data I have created but the grid is a mess. Please help out if you think you know what could be going wrong. Thanks in advance, Viv

  • Multiple autocompletes on same form in socialengine

    - by Mirza Awais
    I am quite new to socialegine module development. I want to use multiple autocomplets on my one form. I have no problem of showing multiple auto completes but problem comes when one selects options from auto complete. I have seen that autocompet.js uses id toValues to show selected option from autocomlte. So if there is only one autocomplete on one form then we can have one element as toValues to show the selected value. But if we have multiple auto completes then how to show the selected item of each auto complete as separately? Using the following code for autocomplete en4.core.runonce.add(function() { new Autocompleter.Request.JSON('to', '<?php echo $this->url(array('module' => 'localspots', 'controller' => 'lookup', 'action' => 'city'), 'default', true) ?>', { 'minLength': 2, 'delay' : 1, 'selectMode': 'pick', 'autocompleteType': 'message', 'multiple': false, 'className': 'message-autosuggest', 'filterSubset' : true, 'tokenFormat' : 'object', 'tokenValueKey' : 'label', 'injectChoice': function(token){ console.log(token.type); var choice = new Element('li', {'class': 'autocompleter-choices', 'html': token.photo, 'id':token.label}); new Element('div', {'html': this.markQueryValue(token.label),'class': 'autocompleter-choice'}).inject(choice); this.addChoiceEvents(choice).inject(this.choices); choice.store('autocompleteChoice', token); }, onPush : function(){ if( $('toValues').value.split(',').length >= maxRecipients ){ $('to').disabled = true; $('to').setAttribute("class", "disabled"); } }, }); });

  • Correct Interactive Website System Design Concepts / Methods?

    - by Xandel
    Hi all, I hope this question isn't too open ended, but a nudge in the right direction is all I need! I am currently building an online accounting system - the idea is that users can register, log in, and then create customers, generate invoices and other documents and eventually print / email those documents out. I am a Java programmer but unfortunately haven't had too much experience in web projects and their design concepts... This is what I have got thus far - A Tomcat web server which loads Spring. Spring handles my DAO's and required classes for the business logic. Tomcat serves JSP's containing the pages which make up the website. To make it interactive I have used JavaScript in the pages (jQuery and its AJAX calls) to send and receive JSON data (this is done by posting to a page which calls a handleAction() method in one of my classes). My question is, am I tackling this project in the right way? Am I using the right tools and methods? I understand there are literally countless ways of tackling any project but I would really love to get feedback with regards to tried and tested methods, general practices etc. Thanks in advance!

  • Sending jQuery.ajax data simultaneous to a form submit

    - by dscher
    I have a bit of a conundrum. I have a form which has numerous fields. There is one field for links where you enter a link, click an add button, and the link(using jQuery) gets added to a link_array. I want this array to be sent via the jQuery.ajax method when the form is submitted. If I send the link_array using $.ajax like this: $.ajax({ type: "POST", url: "add_stock", dataType: "json", data: { "links": link_array } }); when the add link button is selected the data goes no problem to the correct place and gets put in the db correctly. If I bind the above function to the submit form button using $(#stock_form).submit(..... then the rest of the form data is sent but not the link_array. I can obviously pass the link array back into a hidden field in HTML but then I'd have to unpack the array into comma separate values and break the comma-separated string apart in PHP. It just seems 100X easier to unpack the Javascript array in PHP without an other fuss. So, how is it that you can send an array from javascript using $.ajax concurrent to the rest of the $_POST data in HTML? Please note that I'm using Kohana 3.0 framework but really that shouldn't make a difference, what I want to do is add this js array to the $_POST array that is already going. Thanks!

  • Which JavaScript framework for me?

    - by LeonixSolutions
    This is not to be a subjective question; nor is it intended to start a religious war. Which JavaScript framework for me? Until now, I haven't coded any JS at all (no biggy, it's just another language). I have been set in my ways and eschewed any client-side code, lest the user have JS turned off, or try to "just change this a little, to see what happens" - and then expect me to support it. So, until now it has all been server-side, with PHP and an ODBC compliant database. However, I am beginning to see advantages to client-side input validation and improved graphical experience for users which would help me to produce more professional web-based applications. I am looking for a framework which : doesn't have a steep learning curve is full-featured, although that does not mean that the one with the most features wins (remember the 80/20 rule) is mature an stable (even if still in development) integrates well with common IDEs if possible. I use NetBeans for PHP (and occasionally MS visual studio for C# (I seem to have drifted away from Eclipse)) allows me to develop web sites/apps for mobile devices support for Goggle charts (or other charting) would be a bonus has good AJAX/JSON support, but I imagine that they all do Taking that into consideration, is there a "right" framework for me, or does it not really matter? I looked briefly at JQuery and JQueryGui and liked what I saw, but I really don't have time, owing to deadlines, to try them all out and see which one suits me, much as I know that I ought to.

  • lightweight webserver to integrate on client end.

    - by Gopal
    Hi ,... I need to create a python module that will be installed on end-user machines. One of the scripts in that module should be able to receive http POSTS (usually with some JSON formatted data in the body) and then pass on that data to an appropriate python script. I can think of two ways to do this: a) Open a listening server socket on port 80, wait for that http request to come in, parse it and then pass that data to another python script depending on the url that arrived. This method will not require the end-user to install a webserver. End user only has to install the python module. b) Have a mini-webserver installed along with the python module. The webserver will do the same job as [a] via CGI without me requiring to write the CGI functionality. But then the user will have to install the web-server (ie., the hassle of yet another install). Would like to avoid that if possible. IF [b] is the easier option, what is the smallest simplest webserver there is (preferably one that can be packaged as part of the python module itself so that it does not have to be separately installed). Must be opensource of course. regards Gopal

  • Div click and AUTOCOMPLETE password dialog problem

    - by ticky
    And what if you want to autocomplete passwords? I am using similar thing here... I am using Div (id=loginButton) and it has some image - I don't want button control in MVC application (), neither image button. I have hidden input control which is hidden button actually (id=submit_btn). So, on div's (id=loginButton) click, I want to call hidden input control (id=submit_btn) and it's submit action. HTML: <div id="loginButton" > </div> <input type="submit" style="display:none" name="submit" id="submit_btn" /> And JQuery: $(document).ready(function() { $('#loginButton').click(function() { $('#LoginForm').submit(); }); $("form[action$='HandleLoginForm']").submit(function() { Login(); return false; }); return false; }); Function Login() is working with Ajax, without downloading file dialog, but I need also auto complete passwords dialog. function Login() { var urlData = $("#LoginForm").serialize(); if (returnUrl != "") { urlData = $("#LoginForm").serialize() + "&returnUrl=" + returnUrl; } $.ajax({ url: $("#LoginForm").attr("action"), type: "POST", data: urlData, dataType: "json", success: function(result) { if (result.Content != null) { if (result.Valid) { window.location = result.Content.toString(); } else { document.body.innerHTML = result.Content.toString(); } } } }); return false; } It is easy when you use only <input type="submit"> instead of DIV. Form knows that it is for auto completing passwords, but if I use div and force hidden button click like in the code from below, it doesn't show autocomplete password dialog. $('#submit_btn').click(); It will not work. User is logged in, but no reminding for browser to store password. I need this.

I get two errors: XMLHttpRequest cannot load http://soundcloud.com/oembed.json?url=http%3A%2F%2Fapi.soundcloud.com%2Ftracks%2F48419073. Origin null is not allowed by Access-Control-Allow-Origin.

  • Running bundle install fails trying to remote fetch from rubygems.org/quick/Marshal...

    I'm getting a strange error when doing bundle install: $ bundle install Fetching source index for http://rubygems.org/ rvm/rubies/ree-1.8.7-2010.02/lib/ruby/site_ruby/1.8/rubygems/remote_fetcher.rb:304 :in `open_uri_or_path': bad response Not Found 404 (http://rubygems.org/quick/Marshal.4.8/resque-scheduler-1.09.7.gemspec.rz) (Gem::RemoteFetcher::FetchError) I've tried bundle update, gem source -c, gem update --system, gem cleanup, etc etc. Nothing seems to solve this.

  • javascript setTimeout function out of scope.

  • How should a one-man development shop document their code?

    - by CKoenig
    Hi, please let me first describe my situation. I work in an IT department for a small-to-medium sized industrial-company and basically I'm the only real developer (sometimes a second guy joins in for his own projects). I programm mostly in C#/.net. Of course I only programm for internal need (Intranet, reporting, data-driven apps, some mobile apps, ...). My question is how should I document my work? It's a highly dynamic environment (the features and bug fixes I implement are tested by me during production, and go live, often within a day. If I technical documentation like MSDN or even overview diagramms those would take me more time to sync than the whole programming process. Also I feel it's a waste of time because I would be the only one who ever read it. I do understand that if I get sick, leave, or forget this documentation would be valuable. PS:well of course you are right - the quesion is how much and how/where. I try using the XML-docu comments for the public exposed parts but as I'm a believer in self-documenting code the comments mostly restates in plain text what you can read from the method-head itself :(Maybe using the remarks section is the key but if you have 30 lines of code with a 15 line xml-comment in front it just looks dirty (sorry for posting it here but our firewall rejects JSON :( )

  • jQuery ajaxForm "h is undefined" problem

    - by Simon
    I have a form that is brought up in a ajaxed modal which I am using for updating user details. When the modal loads I call a js function: teamCreate: function() { $j("#step1,form#createEditTeam").show(); $j("#step2").hide(); var options = { type: "get", dataType: 'json', beforeSubmit: before, // pre-submit callback success: success // post-submit callback }; $j("form#createEditTeam").ajaxForm(options); function before(formData, jqForm, options){ var valid = $j("form#createEditTeam").valid(); if (valid === true) { $j(".blockMsg").block({ message: $j('#panelLoader') }); return true; // submit the form } else { $j("form#createEditTeam").validate(); return false; // prevent form from submitting } }; function success(data){ if (data.status == "success") { $j(".blockMsg").unblock(); } else { // } }; function error(xhr, ajaxOptions, thrownError){ alert("Error code: " + xhr.statusText); }; } This works just fine when I first submit the form, regardless how many times the modal is opened and closed. However, if I submit the form and then open the modal again and try to submit the form again I get a js error: h is undefined

  • Linq-to-SQL: How to shape the data with group by?

    - by Cheeso
    I have an example database, it contains tables for Movies, People and Credits. The Movie table contains a Title and an Id. The People table contains a Name and an Id. The Credits table relates Movies to the People that worked on those Movies, in a particular role. The table looks like this: CREATE TABLE [dbo].[Credits] ( [Id] [int] IDENTITY (1, 1) NOT NULL PRIMARY KEY, [PersonId] [int] NOT NULL FOREIGN KEY REFERENCES People(Id), [MovieId] [int] NOT NULL FOREIGN KEY REFERENCES Movies(Id), [Role] [char] (1) NULL In this simple example, the [Role] column is a single character, by my convention either 'A' to indicate the person was an actor on that particular movie, or 'D' for director. I'd like to perform a query on a particular person that returns the person's name, plus a list of all the movies the person has worked on, and the roles in those movies. If I were to serialize it to json, it might look like this: { "name" : "Clint Eastwood", "movies" : [ { "title": "Unforgiven", "roles": ["actor", "director"] }, { "title": "Sands of Iwo Jima", "roles": ["director"] }, { "title": "Dirty Harry", "roles": ["actor"] }, ... ] } How can I write a LINQ-to-SQL query that shapes the output like that? I'm having trouble doing it efficiently. if I use this query: int personId = 10007; var persons = from p in db.People where p.Id == personId select new { name = p.Name, movies = (from m in db.Movies join c in db.Credits on m.Id equals c.MovieId where (c.PersonId == personId) select new { title = m.Title, role = (c.Role=="D"?"director":"actor") }) }; I get something like this: { "name" : "Clint Eastwood", "movies" : [ { "title": "Unforgiven", "role": "actor" }, { "title": "Unforgiven", "role": "director" }, { "title": "Sands of Iwo Jima", "role": "director" }, { "title": "Dirty Harry", "role": "actor" }, ... ] } ...but as you can see there's a duplicate of each movie for which Eastwood played multiple roles. How can I shape the output the way I want?

  • jQuery aspx error function always called, even with apparently valid return data

    - by M Katz
    I am making an ajax call using jQuery (jquery-1.5.2.min.js). The server receives the call. fiddler shows the response text coming back apparently correct. But back in javascript my error: function is called instead of my success: function, and the data of the parameters to the error function don't give much clue as to the problem. Here's the function where I make the initial call: function SelectCBGAtClickedPoint() { $.ajax( { type: "GET", dataType: "text", url: "http://localhost/ajax/SelectCBGAtPoint/1/2", success: function( msg ) { alert( "success: " + msg ); }, error: function( jqXHR, textStatus, errorThrown ) { alert( "error: " + jqXHR + textStatus + errorThrown ); } } ); } Here's the function where I handle the call in my cherrypy server code: def ajax( ajax, *args ): with lock: print "ajax request received: " + str( args ) cherrypy.response.headers[ "Content-Type" ] = "application/text" return "{ x: 0 }" Cherrypy is an odd beast, and I was thinking the problem must lie there. But as I say, I see both the query go out and the response come back in Fiddler. Here is what Fiddler shows as the raw view of the response: HTTP/1.1 200 OK Date: Mon, 11 Apr 2011 17:49:25 GMT Content-Length: 8 Content-Type: application/text Server: CherryPy/3.2.0 { x: 0 } Looks good, but then back in javascript, I get into the error: function, with the following values for the parameters (as shown in firebug): errorThrown = "" jqXHR = Object { readyState=0, status=0, statusText="error"} statusText = "error" I don't know where that word "error" is coming from. That string does not appear anywhere in my cherrypy server code. Note that even though I'm returning a JSON string I've set the send and receive types to "text" for now, just to simplify in order to isolate the problem. Any ideas why I'm getting this "error" reply, even when errorThrown is empty? Could it be that I haven't properly "initialized" either jQuery or jQuery.ajax?

  • Escape Quote in C# for javascript consumption

    I have a ASP.Net web handler that returns results of a query in JSON format public static String dt2JSON(DataTable dt) { String s = "{\"rows\":["; if (dt.Rows.Count > 0) { foreach (DataRow dr in dt.Rows) { s += "{"; for (int i = 0; i < dr.Table.Columns.Count; i++) { s += "\"" + dr.Table.Columns[i].ToString() + "\":\"" + dr[i].ToString() + "\","; } s = s.Remove(s.Length - 1, 1); s += "},"; } s = s.Remove(s.Length - 1, 1); } s += "]}"; return s; } The problem is that sometimes the data returned has quotes in it and I would need to javascript-escape these so that it can be properly created into a js object. I need a way to find quotes in my data (quotes aren't there every time) and place a "/" character in front of them. Example response text (wrong): {"rows":[{"id":"ABC123","length":"5""}, {"id":"DEF456","length":"1.35""}, {"id":"HIJ789","length":"36.25""}]} I would need to escape the " so my response should be: {"rows":[{"id":"ABC123","length":"5\""}, {"id":"DEF456","length":"1.35\""}, {"id":"HIJ789","length":"36.25\""}]} Also, I'm pretty new to C# (coding in general really) so if something else in my code looks silly let me know.

  • Canonical resource for forms-based design in ASP.NET MVC?

    - by Robert Harvey
    Is there a resource on the web that describes various form scenarios in ASP.NET MVC, and gives example solutions within a sensible, consistent design philosophy? Examples of such scenarios might be: One-to-many forms, like invoice data-entry forms. Foreign-table forms such as Add New User in a form that requires specifying a user Forms that require dynamic interaction, using Ajax or JSON. Popup forms Forms requiring multiple data records to be input, without postbacks. Note that there is considerable conceptual and technological overlap among these example scenarios. I am aware that there is a vast patchwork quilt of available technologies and examples out there that provide partial solutions and pieces of solutions, such as jQuery Ajax, CSS, and so forth. But I would like guidance in using these technologies in more effective and consistent ways. I am not considering web forms integration with an ASP.NET MVC application; I would still like my applications to be pure MVC. Nor am I, at the moment, considering a paid solution like Telerik. But I would like to know if someone has already done some of the work combining these technologies into a consistent, cohesive whole, that follows a sensible design philosophy. (an open source framework, perhaps?)

  • passing callback function accross windows causing error with ie ...

    - by krul
    I have a problem with IE causing two errors: 1. Object doesn't support this property or method 2. Call was rejected by callee. My Intention: To call window.opener.myObject method that is going to retrieve some data using ajax and pass in callback function that live as nested function in popup window that initiated call that is going to handle response data and modify popup window html accordingly. Here is a scenario: I pull up popup window that handles some specific operation. This popup window calling window.opener.myObject method that using ajax call. I'm passing in popup window function that is going to handle response and it works with ff and safari but not with ie. Here is code sample //RELEVANT SCRIPT ON POPUP WINDOW $('#myButton').live('click', function() { var h = window.opener.myObject, p = { 'p1': 1 }; var responseHandler = function(responseObj) { //in IE we never got here if (!responseObj) { alert('Unexpected error!! No response from server'); return false; } //..handle response }; p.p1 = $('#control').val(); h.executeMethod(p, responseHandler); }); //RELEVANT SCRIPT ON WINDOW OPENER MYOBJECT try { $.ajax({ type: 'POST', async: true, url: url, data: postData, dataType: "json", contentType: 'application/x-www-form-urlencoded; charset=utf-8', success: r, // r here is reference to my responseHandler popup window function error: handleError }); } catch (ex) { alert(ex.message); } Any tips?

  • Google Translate API for iPhone - UTF8 problem in Chinese Translation

    - by Sky Chen
    I've tested a workable translation API url by: http://translate.google.com/translate_a/t?client=t&text=%E5%BB%A3%E5%A0%B4&langpair=zh|zh-CN And it returns the correct result as the following which is in JSON format: {"sentences":[{"trans":"??","orig":"??","translit":"Guangchang"}],"src":"zh-CN"} However, when I try to use this function in XCode, I experienced this problem ... Here is my code: NSData *data; NSString *urlPath = [NSString stringWithFormat:@"/translate_a/t?client=t&text=%@&langpair=zh|zh-CN",qText]; NSURL *url = [[NSURL alloc] initWithScheme:@"http" host:@"translate.google.com" path:urlPath]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:url]; [request setHTTPMethod:@"GET"]; NSURLResponse *response; NSError *error; data = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; NSString *result = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; //Problem's here. It returns nil. NSLog(result); Initially I guessed it's encoding problem so I tried other encoding as well (NSISOLatin1StringEncoding) , but I got wrong answer: {"sentences":[{"trans":"ã ","orig":"ã ","translit":"Tu¨¯ "}],"src":"zh-CN"} Does anyone know how to solve this problem? Thank you very much!

  • jQuery: How to parse a multidemensional array?

    - by Allen G
    I'm not sure if the array is too deep or what, but I can't seem to get anything other than the keys and undefines. Help please! I'm using Codeigniter for development. Here is the PHP then the jQuery: $term = $this->input->post('search_term'); $this->db->like('book_title', $term); $search_query = $this->db->get('books'); $return = array(); $i = 0; if ($search_query->num_rows() > 1) { foreach($search_query->result() as $s) { $return['books']['book_id'] = $s->book_id; $return['books']['book_title'] = $s->book_title; $return['books']['book_price'] = $s->book_price; $i++; } } elseif ($search_query->num_rows() == 1) { echo 1; $i = 0; $return['book_id'] = $search_query->row('book_id'); $return['book_title'] = $search_query->row('book_title'); $return['book_price'] = $search_query->row('book_price'); } elseif ($search_query->num_rows() == 0) { echo 0; } echo json_encode($return); $("#search").change(function() { var searchTerm = $(this).val(); $.post("/contentcreator/search_by_term", { search_term: searchTerm }, function(data) { $("#book_scroller").empty(); var lengthHolder = data.books; for (var i = 0; i data.books.length; i++) { var row = '<li id="book_item_' + l + '">' + data.books['book_title'] +'</li>'; $("#book_scroller").append(row); }; i++; }, "json"); }); Thanks!

  • backbone js or knockout js as a web framework with jquery mobile

    - by Dan
    without trying to cause a mass discussion I would like some advice from the fellow users of stack overflow. I am about to start building a mobile website that gets it data from JSON that comes from a PHP rest api. I have looked into different mobile frameworks and feel that JQM will work best for us as we have the knowledge of jQuery even though a little large. Currently at work however we are using jQuery for all our sites and realise that now we are building a mobile website I need to think about javascript frameworks to move us onto a more MV* approach, which I understand the benefits of and will bring much needed structure to this mobile site and future web applications we may bring. I have made a comparision table where I have managed to bring the selection down to 2 - backbone and knockout. I have been looking around the web and it seems that there is more support for backbone in general and maybe even more support for backbone with JQM. http://jquerymobile.com/test/docs/pages/backbone-require.html One thing I have noticed however is that backbone doesnt support view bindings (declarative approach) whereas knockout does - is this a massive bonus? one of the main reasons for using a mv* for us is to get more structure - so I would like to use the library that will intergrate best with jQuery and especially jQuery mobile. neither of them seem to have that similar syntax... Thanks
