  • jQuery get request against Sinatra does not get text

    - by jerhinesmith
    I have a very simple sinatra site that I'm trying to access via ajax through jQuery. To keep things incredibly simple, this code snippet: get '/behavior_count' do "60" end which returns "60" in the browser, shows up as an empty string when attempting to access the site via $.get in jQuery. The strange part is in Firebug, while the Response is empty, the HTTP header correctly describes Content-Length as 2, and I can see the request show up on the server. Is there something specific to Sinatra that isn't returning my data, or am I not using jQuery correctly? If it helps, I also tried this code: get '/behavior_count' do content_type 'text/plain', :charset => 'utf-8' "60" end and my jQuery looks like $.get('http://mysite:4567/behavior_count'); // Ignore the response, but // watch the request in firebug Any ideas?

  • Elegant solution for multiple forms on single page

    - by NFicano
    I'm building a web application (in Django) that will accept a search criteria and display a report - once the user is satisfied with the results, save both the criteria and a reference to these objects back to the database. The problem I'm having is finding an elegant solution for having 2 forms: Display (GET) the results of their criteria. Enter in some descriptions, and save (POST) everything back to the database. I'm leaning towards AJAX for the GET stuff and a POST for the save, but I wanted to make sure there wasn't a more elegant solution first.

  • How can you pass GET values to another url in php? GET value forwarding

    - by gobackpacking
    Ok, so I'm using Jquery's AJAX function and it's having trouble passing a URL with a http address. So I'm hoping to "get" the GET values and send them to another URL — so: a local php file begin passed GET values, which in turn forwards the GET values to another url. Maybe curl is the answer? I don't know. It's got to be a very short answer I know. pseudo code: //retrieve the GET values $var retrieve [GET] //passing it to another url send get values to url ($var, url_address)

  • Switching to FormViewMode.Edit is very slow

    - by Tim
    When i switch an ASP.Net Formview from readonly mode to edit mode it takes more than 6 seconds(from edit to readonly takes a split second). I have no idea whats the reason for it. The EditItemTemplate contains a lot of controls(table,textboxes,dropdownlists) but in fact not more than the ItemTemplate has. Yet i have even commented out the complete FormView.DataBound where the controls are data bounded but without significant change. My ASP.Net Web Apllication is using Ajax and the Formview is completely nested in an UpdatePanel. Any suggestions or assumptions for this behaviour?

  • MVC partial page update

    - by GB
    Hello, I have an MVC project where I have a form with fields a user can enter and save. On that same page I have a table which shows a brief listing of information that the user just saved. The problem I am having is trying to update only the table after a save and not an entire page refresh. Is this possible in jquery or MVC? If so does anyone have an example. Here is what the action in the controller looks like: public ActionResult RefreshList() { string _employeeID = Request.QueryString["empIDSearch"]; this.ViewData["coursehistorylist"] = _service.ListCoursesByEmpID(_employeeID); return View("CourseHistoryList"); } The function in the view: (and this is where I'm confused on how to update only the table) $.ajax({ url: "/Home/RefreshList", type: "POST", success: function(result) { alert("got here"); }, error: function(xhr, ajaxOptions, thrownError) { alert(xhr.status + " " + thrownError + " " + ajaxOptions); } }); Thanks.

  • Best strategy for HTML parcial rendering based on multiple dropdown values

    - by pv2008
    I have a View that renders something like this: "Item 1" and "Item 2" are <tr> elements from a table. After the user change "Value 1" or "Value 2" I would like to call a Controller and put the result (some HTML snippet) in the div marked as "Result of...". I have some vague notions of JQuery. I know how to bind to the onchage event of the Select element, and call the $.ajax() function, for example. But I wonder if this can be achieved in a more efficient way in ASP.NET MVC2.

  • Implementing a client for ActiveMQ events

    - by recipriversexclusion
    I can listen to events from a certain topic in an ActiveMQ server using a simple asynchronous listener and print the incoming events to the console (code to that actually comes as an example in the activemq-cpp library). I would like to create clients on other machines that will listen to these events and update their displays. My question is: how to best go about doing this? Are there any Ajax examples you can point me that implement similar functionality? Or is there another technology (comet?) that is better to use for this scenario? How can I display the events in teh browser window as they are received by the client, should I use JQuery?

  • Read data from form

    - by Superhuman
    This is a strange question, I've never tried to do this before. I have a repetitive process requiring that I copy and paste data from text boxes in one program into another program for further processing. I'd like to automate this process using VB .NET. The application from which the data is gathered isn't mine, so I don't have ActiveX-like access to its controls. How would you write an application to gain access to a form from another application, to be able to find the controls on the form, and gather the values from them? Just experimenting, I've used the following code. This resulted in only the name of the form to which this code belongs. It didn't find the names of any other forms I have open, and I have a lot open to choose from. This is frustrating because it's only step one of what I'll need to do to make my life easier... Public Declare Function EnumWindows Lib "user32" (ByVal lpEnumFunc As CallBack, ByVal lParam As Integer) As Integer Public Delegate Function CallBack(ByVal hwnd As IntPtr, ByVal lParam As IntPtr) As Boolean Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim cb As New CallBack(AddressOf MyCallBack) EnumWindows(cb, 8) End Sub Public Function MyCallBack(ByVal hwnd As Long, ByVal lparam As Long) As Boolean Dim frm As System.Windows.Forms.Control frm = System.Windows.Forms.Form.FromHandle(hwnd) If frm Is Nothing Then Return True If frm.Text <> "" Then TextBox1.Text += frm.Text & ", " End If Return True End Function Does anyone have a recommendation? Thanks, SH

  • How to pass some data to JQuery AJAX in CAKEPHP

    - by kwokwai
    Hi all, I am learning how to use JQuery to help check data availability. To start with it, I wrote a few lines of codes using cakePHP. I have written a function in a Controller for checking data input, and the URL is like this: http://www.mywebsite.com/controllers/action/avariable I was trying to pass the value in a Input TextBox field using the JQuery Ajax to the URL above,but I don't know why it is not working in passing a variable to the Controller's action.

  • Forming a SOAP request message through WSDL

    - by Shahzad
    I'm very new to webservices. I'm trying to figure out how I can formulate a request message (and determine what the response message) would be based on the wsdl description that I have. This is from a third party web service. The WSDL description that I have access to gives me a bunch of information like <types> <message> <operation> etc. But in the examples that I've seen online, it's showing the request mesage within the "soap:envelope" tag. What am I missing? Eventually I'd like to be able to call this webservice using JQuery. But I can't even figure out how to formulate the request message let alone make an ajax call to it. any help would be appreciated.

    Why does this turn up null instead of being set to the data returned from the ajax call? It must be something simple i am overlooking. var message; $(document).ready(function(){ fbFetchMessage(); alert(message); }); function fbFetchMessage(){ var url = "http://graph.facebook.com/companyname/feed?callback=?"; $.getJSON(url,function(json){ message = json.data[0].message; }); }

  • How to dynamically add a Javascript function (and invoke)

    - by whitey
    Based on a click event on the page, via ajax I fetch a block of html and script, I am able to take the script element and append it to the head element, however WebKit based browsers are not treating it as script (ie. I cannot invoke a function declared in the appended script). Using the Chrome Developer Tools I can see that my script node is indeed there, but it shows up differently then a script block that is not added dynamically, a non-dynamic script has a text child element and I cannot figure out a way to duplicate this for the dynamic script. Any ideas or better ways to be doing this? The driving force is there is potentially a lot of html and script that would never be needed unless a user clicks on a particular tab, in which case the relevant content (and script) would be loaded. Thanks!

  • Reading PDF form field data from Flex 4 ( via php or coldfusion )

    - by Brian Russel Davis
    Been searching web for an answer for this for a MONTH. I am not an expert in Coldfusion. So supposedly this is easy in CF -- but the mark-up confuses the HECK out of me. So here I am. I have managed to import and read a PDF using the CF Proxy for Actionscript: http://forums.adobe.com/thread/754629?tstart=0 --- BUT --- After all my trouble there, the precious form filed information that I was looking for was not there in the PDF info object. GRRRR. So I am back to looking for a way to do this with CFC's or CFM's or PHP. All I want is this: Read the PDF from a Flex app. GET the form field information. WRITE a new PDF with the form field values. I have found so many close but no cigar options ... and I have tried so many that failed. There are so many free PDF this and that out there. But Adobe seems to reserve the real functionality for themselves. All the free options don't seem to have access to the form data? Anyways I am so exhausted with looking for ways to do this. I need help!

  • how can I reliably check that requests to my service file have come from my website?

    - by woot586
    I have a service.php class that I use to service AJAX calls from my website. To prevent other people accessing the service using PHP CURL I would normally check the request has come from mysite, and if they are not then just redirect to my home page e.g. if($_SERVER['HTTP_REFERER'] != "http://www.mysite.com"){ header('location: http://www.mysite.com'); exit; } I read in the PHP holy bible: http://www.php.net/manual/en/reserved.variables.server.php that "Not all user agents will set this, and some provide the ability to modify HTTP_REFERER as a feature. In short, it cannot really be trusted." So if this method is not reliable, my question is how can I reliably check that requests to my service file have come from my website? Thanks for any help you can provide!

  • DropDownList always does full-page postback, the first time it fires.

    - by CodexArcanum
    I have an ASP.NET page using the AJAX library. There is a dropdownlist inside an UpdatePanel, which on index changing is supposed to update a different UpdatePanel to modify a grid control. But after the page first comes up, and you adjust the ddl, the entire page postbacks, followed by a (correct) partial postback. After this one time, every other usage of the ddl performs correctly, trigger partial postbacks. Both the panel and the ddl are being added from code. The UP is Conditional updates and ChildrenAsTriggers = true. The dropdownlist is AutoPostBack true and has an event set up on SelectedIndexChanged. So what is going on? I've tried adjusting every setting I can think of and still the page completely refreshes once, then works fine after that.

  • JQuery pass model to controller

    I want to pass the mvc page model back to my controller within a Javascript Object. How would I do that? var urlString = "<%= System.Web.VirtualPathUtility.ToAbsolute("~/mvc/Indications.cfc/ExportToExcel")%>"; var jsonNickname = { model: Model, viewName: "<%= VirtualPathUtility.ToAbsolute("~/Views/Indications/TermSheetViews/Swap/CashFlows.aspx")%>", fileName: 'Cashflows.xls' } $.ajax({ type: "POST", url: urlString, data: jsonNickname, async: false, success: function (data) { $('#termSheetPrinted').append(data); } }); So where it says model: Model, I want the Model to be the actual page model that I declare at the top of the page: Inherits="System.Web.Mvc.ViewPage<Chatham.Web.Models.Indications.SwapModel>" How can I do that?

  • Are there viable alternatives for Web 2.0 apps besides lots of Javascript?

    - by djembe
    If you say find C-style syntax to be in the axis of evil are you just hopelessly condemned to suck it up and deal with it if you want to provide your users with cool web 2.0 applications - for example stuff that's generally done using JQuery and Ajax etc? Are there no other choices out there? We're currently building intranet apps using pylons and a bunch of JavaScript along with a bit of Evoque. So obviously for us the world would be a better place if instead something equivalent existed written in like PythonScript. But I've yet to seen anything approaching that aside from the Android system's ASE - but obviously that's something rather unrelated. Still - if browsers could support other scripting languages....
