  • Ruby array, javascript and json issue

    - by JohnMerlino
    Hey all, I am unable to get a highcharts plugin to render a chart in a rails application: http://github.com/loudpixel/highcharts-rails I believe it has something to do with the sql queries to the database placed in a ruby array, which the javascript is unable to intepret. This is what I have: def panels pass = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 1') fail = Student.find_by_sql('SELECT COUNT(*) FROM students WHERE student_state = 2') student_data = [ {:name => 'Pass', :y => pass}, {:name => 'Fail', :y => fail} ] pie_label_formatter = ' function() { if (this.y > 15) return this.point.name; }' pie_tooltip_formatter = ' function() { return "<strong>" + this.point.name + "</strong>: " + this.y + " %"; }' @pie_chart = Highchart.pie({ :chart => { :renderTo => "pie-chart-container", :margin => [50, 30, 0, 30] }, :plotOptions => { :pie => { :dataLabels => { :formatter => pie_label_formatter, :style => { :textShadow => '#000000 1px 1px 2px' } } } }, :series => [ { :type => 'pie', :data => student_data } ], :subtitle => { :text => 'April 2010' }, :title => { :text => 'Student Status Chart' }, :tooltip => { :formatter => pie_tooltip_formatter }, }) Note if I put this: :data = student_data.to_json It actually returns a json string of my query as text in the browser. Also, if I hard code values (e.g. :y = 1), it will render the chart properly. However, any database query will not render the chart properly. So I'm not sure exactly what the issue is. Any suggestions? Thanks.

  • Can I trigger an Update Panel from a Drop Down list in a User Control

    - by Jisaak
    I have a user control in a master page with two drop down lists. When the user selects an item out of either ddl, I want to load a specific user control inside an update panel on the content page. I know how to load the controls in the update panel, but I can't figure out how to get the user control to trigger the update panel. Any suggestions are very much appreciated.

  • ASP.NET MVC jQuery autocomplete with url.action helper in a script included in a page.

    - by Boob
    I have been building my first ASP.NET MVC web app. I have been using the jQuery autocomplete widget in a number of places like this: <head> $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); </head> The thing is I have this jQuery code in a number of different places through my web app. So i thought I would create a seperate javascript script (script.js) where I could put this code and then just include it in the master page. Then i can put all these repeated pieces of code in that script and just call them where I need too. So I did this. My code is shown below: In the site.js script I put this function: function doAutoComplete() { $("#model").autocomplete({ source: '<%= Url.Action("Model", "AutoComplete") %>' }); } On the page I have: <head> <script src="../../Scripts/site.js" type="text/javascript"></script> doAutoComplete(); </head> But when I do this I get an Invalid Argument exception and the autocomplete doesnt work. What am I doing wrong? Any ideas?Do i need to pass something to the doAutoComplete function?

  • What's a simple way to web-ify my command-line daemon?

    - by dreeves
    Suppose I have a simple daemon type script that I run on my webserver. I run it in a terminal, with gnu screen, so I can keep an eye on it. That works fine (incidentally, I use this trick). But now suppose I'd like to make a web page where I can keep an eye on my script's output. What's the easiest way to do that? Notes: This is mainly for myself and a couple co-hackers so if websockets is the answer and it only works on Chrome or something, that's acceptable. This question is asking something similar: http://stackoverflow.com/questions/1964494/how-to-make-all-connected-browsers. But I'm hoping for a simpler, quick-and-dirty solution, and especially a general way to quickly do this for any script I might want to keep an eye on from a browswer.

    - by Ken
    Hi, I'm trying to make a script that automatically starts uploading after the data has been enter in the database(I need the autoId that the database makes to upload the file). When I run the javascript the scripts runs the php file but it fails calling the other php to upload the file. too much recursion setTimeout(testIfToegevoegd(),500); the script that gives the error send("/projects/backend/nieuwDeeltaak.php",'deeltaakNaam='+f.deeltaaknaam.value+'&beschrijving='+ f.beschrijving.value+'&startDatum='+f.startDatum.value+'&eindDatum='+f.eindDatum.value +'&deeltaakLeider='+f.leiderID.value+'&projectID='+f.projectID.value,id); function testIfToegevoegd(){ if(document.getElementById('resultaat').innerHTML == "<b>De deeltaak werd toegevoegd</b>"){ //stop met testen + upload file document.getElementById('nieuwDeeltaak').target = 'upload_target'; document.forms["nieuwDeeltaak"].submit() }else{ setTimeout(testIfToegevoegd(),500); } } testIfToegevoegd(); sorry for the dutch names we have to use them it is a school project. when I click the button that calls all this for a second time (after the error) it works fine.

    I have a dundas pie chart which when clicked issues a client callback which updates another chart associated with it. Basically its like a drill down thing. I also want to update my gridview based on the user's selection of the pie. But since the update of chart is being done using dundas client callback I'm unable to rebind my Gridview. Is there any way to do it? .

  • jQuery .get appends an unknown variable to URL

    - by ILMV
    I'm using this code as the starting point to an overhaul of our JavaScript framework: $("#get").click(function(){ $("#result").html(ajax_load); $.get( "http://www.google.com", {}, function(responseText){ $("#result").html(responseText); }, "html" ); }); But when the request is made it includes a variable within the URL that I am unfarmiliar with, here is what Firebug says it's requesting: http://www.google.com/?_=1268993359215 How do I get rid of this, when we target our internal scripts it's firing a 404 error :-( Cheers!

  • Editing a Gridview row with drop-down lists gets too wide - how can I use popup panels instead?

    - by David
    I have a series of GridViews in a Tab Panel - databound to a generic List of Business Objects. The columns in the Gridview are all similar to the following: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:DropDownList ID="ddlCompany" runat="server"></asp:DropDownList> </EditItemTemplate> </asp:TemplateField> The GridView generates the "Edit" link at the beginning of the row, all the events fire ok. The problem is that the data is getting long. When in 'display mode', it's fine because the GridView control is smart enough to break some text into multiple lines (in particular Project, Title and Worker names can get pretty long). The problem come in editing mode. Drop-down lists DON'T break entries into multiple lines (for obvious reasons). Going into Edit ode on a row in the Gridview can make the Griview expand horizontally to twice the screen size (blowing through the width limits in the Master page and CSS but that's only a related problem). What I need is something like the ModalPopup - but trying to tie it to an ID in an EditItemTemplate gives me errors when the page renders (because the 'ddlXXXX' doesn't exist at the time). In addition I don't know how to dynamically populate the panel so that I can get a response from it (like the ID of the Company they selected). I'm also trying to avoid javascript and would like this to be a 'pure' aspx/code-behind solution (for simplicity's sake among others). All the examples I find are of Modal Popups with the panels pre-defined. Even if it (the popup panel) were something like a list of checkboxes, it could be databound to the SortedList I have ready to go and an OK/Cancel button combination to accept or ignore things. I'm just not sure of what goes where. I'm open to suggestions. Thanks in advance. EDIT: Final solution looks as follows: <asp:TemplateField HeaderText="Company" SortExpression="Company.ShortName"> <ItemTemplate> <asp:Label ID="lblCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:Label> </ItemTemplate> <EditItemTemplate> <asp:LinkButton ID="lnkCompany" runat="server" Text='<%# Bind("Company.ShortName") %>'></asp:LinkButton> <asp:Panel ID="pnlCompany" runat="server" style="display:none"> <div> <asp:DropDownList ID="ddlCompany" runat="server" ></asp:DropDownList> <br/> <asp:ImageButton ID="btnOKCo" runat="server" ImageUrl="~/Images/greencheck.gif" OnCommand="PopupButton_Command" CommandName="SelectCO" /> <asp:ImageButton ID="btnCxlCo" runat="server" ImageUrl="~/Images/RedX.gif" /> </div> </asp:Panel> <cc1:ModalPopupExtender ID="mpeCompany" runat="server" TargetControlID="lnkCompany" PopupControlID="pnlCompany" BackgroundCssClass="modalBackground" CancelControlID="btnCxlCo" DropShadow="true" PopupDragHandleControlID="pnlCompany" /> </EditItemTemplate> </asp:TemplateField> And in the code-behind, lstIDLabor is the generic List of data lines (of which Company is one of the properties that is also a business object) that is bound to the GridView: Sub PopupButton_Command(ByVal sender As Object, ByVal e As CommandEventArgs) Dim intRow As Integer Dim intVal As Integer RestoreFromSessionVariables() Select Case e.CommandName Case "SelectCO" intRow = grdIDCostLabor.EditIndex Dim ddlCo As DropDownList = CType(grdIDCost.Rows(intRow).FindControl("ddlCompany"), DropDownList) intVal = ddlCo.SelectedValue lstIDLabor(intRow).CompanyID = intVal lstIDLabor(intRow).Company = Company.Read(intVal) Case Else ' End Select MakeSessionVariables() BindGrids() End Sub

  • Whats wrong with this function? .each related

    - by Ritz
    When I uncomment the alert the data is there... like: { 'Huishoudelijke hulp': 'Huishoudelijke hulp', 'Verpleging thuis': 'Verpleging thuis', 'Verzorging thuis': 'Verzorging thuis', '24 uurs zorg': '24 uurs zorg', 'Ondersteunende begeleiding': 'Ondersteunende begeleiding', } But instead of populating the key and the value it takes the whole var and start to create a key and value pair for each character. You can see this in action here: http://www.zorgzuster-zeeland.nl/site/static/calendar_test.php create a task in the calendar and then try to edit the task by clicking on it. It should populate the dropdown field properly. When i create a static var with the same values the dropdown works. static variable var zvmlist = { 'Huishoudelijke hulp': 'Huishoudelijke hulp', 'Verpleging thuis': 'Verpleging thuis', 'Verzorging thuis': 'Verzorging thuis', '24 uurs zorg': '24 uurs zorg', 'Ondersteunende begeleiding': 'Ondersteunende begeleiding', }; This is my function, anybody has a clue? $.get('get_zorgvormen.php', function(zvmlist) { //alert("Data Loaded: " + zvmlist); $.each(zvmlist, function(key, value) { var selected=''; if(key==eventdata.title){var selected='selected' } $('<option value="'+key+'" '+selected+'>'+value+'</option>').appendTo($('#calendar_edit_entry_form_title')); }); });

  • Why is this XMLHttpRequest sample from Mozilla is not working in Firefox 3?

    - by j0rd4n
    I'm trying to get the sample code from Mozilla that consumes a REST web service to work under Firefox 3.0.10. The following code does NOT work in Firefox but does in IE 8! Why is this not working? Does IE 8 have support for XMLHttpRequest? Most examples I've seen use the ActiveX allocation. What should I be doing? XMLHttpRequest seems more standardized. Sample: var req = new XMLHttpRequest(); req.open('GET', 'http://localhost/myRESTfulService/resource', false); // throws 'undefined' exception req.send(null); if(req.status == 0) dump(req.responseText); The open statement is throwing an exception with the description 'undefined'. This is strange as I allocate the req object, am running it in Firefox, and checked to make sure it is defined before calling open (which it says it is of type 'object'). I've also tried the asynchronous version of this with no luck. EDIT 2: Below is my most recent code: function createRequestObject() { if( window.XMLHttpRequest ) { return new XMLHttpRequest(); } else if( window.ActiveXObject ) { return new ActiveXObject( "Microsoft.XMLHTTP" ); } return null; } function handleResponse( req ) { document.writeln( "Handling response..." ); // NEVER GETS CALLED if( req.readyState == 0 ) { document.writeln( "UNITIALIZED" ); } else if( req.readyState == 1 ) { document.writeln( "LOADING" ); } else if( req.readyState == 2 ) { document.writeln( "LOADED" ); } else if( req.readyState == 3 ) { document.writeln( "INTERACTIVE" ); } else if( req.readyState == 4 ) { document.writeln( "COMPLETE" ); if( req.status == 200 ) { document.writeln( "SUCCESS" ); } } } document.writeln( "" ); var req = createRequestObject(); try { document.writeln( "Opening service..." ); req.onreadystatechange = function() { handleResponse( req ); }; req.open('POST', 'http://localhost/test/test2.txt', true); // WORKS IN IE8 & NOT FIREFOX document.writeln( "Sending service request..." ); req.send(''); document.writeln( "Done" ); } catch( err ) { document.writeln( "ERROR: " + err.description ); } EDIT 3: Alright, I reworked this in jQuery. jQuery works great in IE but it throws 'Undefined' when running from Firefox. I double checked and 'Enable JavaScript' is turned on in Firefox - seems to work fine in all other web pages. Below is the jQuery code: function handleResponse( resp ) { alert( "Name: " + resp.Name ); alert( "URL: " + resp.URL ); } $(document).ready( function() { $("a").click( function(event) { try { $.get( "http://localhost/services/ezekielservices/configservice/ezekielservices.svc/test", "{}", function(data) { handleResponse( data ); }, "json" ); } catch( err ) { alert("'$.get' threw an exception: " + err.description); } event.preventDefault(); }); } ); // End 'ready' check Summary of Solution: Alright, web lesson 101. My problem was indeed cross-domain. I was viewing my site unpublished (just on the file system) which was hitting a published service. When I published my site under the same domain it worked. Which also brings up an important distinction between IE and Firefox. When IE experiences this scenario, it prompts the user whether or not they accept the cross-domain call. Firefox throws an exception. While I'm fine with an exception, a more descriptive one would have been helpful. Thanks for all those who helped me.

  • iphone navigation tutorial with simple form

    - by iamthewit
    Hi All, I'm looking to create quite a basic app with a very simple navigation system but each of the tutorials I've come across so far go into too much depth or just involve lots of different form elements. I want to keep it as straight forward and simple as I can. If anyone knows of any tutorials that can show me how to create a root view with say 5 or 6 sub views each displaying a form for collecting different types of data I would be very grateful. This seems like quite a simple thing to achieve but so far I havent found anything that specifically relates to what I want to do. thanks in advance!

  • ASP .NET 4.0 How do I Redirect/Override the default CDN path for ScriptManager when EnableCDN=true

    - by plattnum
    I am using the EnableCdn=true in my ScriptManager so that WebResource.axd and ScriptResource.axd are overridden with static links to JS libraries at the MS CDN service as follows: <asp:ScriptManager ID="ScriptManager1" runat="server" EnableCdn="true" /> How do I override the CDN URLs or service so that I can retrieve the scripts over HTTPS from the MS CDN service rather than HTTP to avoid the browser mixed mode message? or for that matter a different or my own CDN service entirely.
