I want to call a webservice using jQuery.ajax() but the webervice doesn't get called. - If I change the url: to reference a .ashx file it gets called but not .asmx?
Here's the code I'm using:
jQuery.ajax({
type: "POST",
url: "/services/CheckUsername.asmx/CheckUsername", // this doesn't get called
//url: "/services/CheckUsername.ashx/ProcessRequest", this gets called
data: '{ "context": "' + "username" + '"}',
contentType: 'application/json; charset=utf-8',
dataType: 'json',
success: function (msg) {
alert("Result: " + msg);
},
error: function (XMLHttpRequest, textStatus, errorThrown) {
alert("Error: " + textStatus)
}
The .ashx file gets called but a parsererror is retuned because it's returning http context - how can I modify this to get a string return type from a webservice?
I am new to ASP.NET (2 months) and my very first assignment is to create a website for a municipality. Purchasing as much reading material as possible, I got started and after some time, I have a decent website (coded in C#) that is ready to be internally tested on the departmental webserver. The Web server is running IIS 7 and the pages were developed with Visual Studio 2010. On the main default page, I wanted to implement a slide show using the AJAXControlToolkit which I installed. I watched the ASP.net tutorial [URL] and literally coded my slide show verbatim. I try to launch my slideshow within my default.aspx page and absolutely nothing happens. The steps that I took are
1. Created a webservice (SlidesService.asmx) which generated a code behind file (SlidesService.cs).
2. I created the web method GetSlides() containing a 22 element array which I place in the code behind file.
3. Implement the ToolkitScriptManager establishing my image control.
4. Defined my Previous, Play and Next buttons.
5. Implemented my SlideShowExtender providing my SlideShowServicePath and SlideShowServiceMethod.
Assumptions: In doing all of the above, I noticed that the SlidesService.asmx file needs no code (as I placed all code within the codebehind file). The SlidesService.cs code behind file should reside in the App_Code folder whereas the the SlidesService.asmx file can remain in the root folder. No Button e.g Button_Click needs to be attached to the code behind source file. If I have conveyed my steps properly, can anyone shed some light on why when clicking the play button, nothing happens? Code is listed below.
I have a webservice that wraps an unmanaged C++ dll. I'm wondering how I should handle state and multiple connections? I'm thinking that the unmanaged dll will be shared across all connections...is this the case? Note that I am using a shared host so I have limited abilities to modify IIS specifically. If the unmanaged dll is not shared and will have a unique instance for every connection then I have nothing to worry about. If it's the case it's shared then I guess I will have to persist the unmanaged state on a per-connection basis through a DB?
How do I protect a webservice if it is called from ajax ?
Update: I realize that my question didn't reflect what I intended to ask. I don't want user to be able to do the request by pointing to it with its webbrowser but only in the context of my app.
I am using this basic jQuery modal window example: http://www.ericmmartin.com/projects/simplemodal-demos/
It works fine if I set it up to click a standard HTML button. However, I want to use this as an action dialog window so I need to automatically open it via code-behind. I wrapped the jQuery like this: function launchIt() {
Do not know if you know this plugin but basically it displays a tree.I'm having trouble using it, and would like your help to use this plugin.This link has a presentation of the plugin.Basically I have the project groups and projects where I display the tree, each project within their respective group. And once the user clicks on the group, the group is expanded showing all projects that group.Here is an example of use.
My environment is asp.net (C #)I would like to use this plugin to display the group's projects and projects under the tree:Follow the link for a code, as far as I could do.I would like to view the ul and li tags in the tree.
I have the following code where the function codeaddress geocodes the text feild value and returns geocoded value , geocoded value is stored in variable example ,how will i return the variable v2 to the function call and post to asmx webservice.
I want to call an action method when an textbox gets focus to get a description of the model object that field is associated with from a database.
I have this jQuery function:
[code]...
It works fine as far as getting the test text, but the problem is if I set a breakpoint in the action method, I see that it gets called over and over, not just when i change focus in the text boxes...

I have seen that ASP .Net Code Behind files are really slow. I have used local web services which i call from jquery ajax function and they are fast. But i am still confused? Should i display dynamic data from code behind or web services?
I let my web service return a JSON Object and i assign relevant elements from that JSON object to different html elements like (image, div etc.)
I have a controller method "SaveFile" that attempts to download a binary stream to client's PC using the FileContentResult. If I make the call as a post from the controller corresponding view everything works OK. I want to call the same controller method "SaveFile" from a jquery function via an .ajax call, when I do the function returns an error and the responseText is the contents of the file to be written. What would I have to do to get the same behavior from a jQuery function as if the MVC framework handled the call via the submit button? Or an alternate solution would be to determine how can I catch the browser's download dialog close event.
I have asp.net webpage in that image div should change image when a button is clicked. I want to add fade in and out effect so I use jquery. The code is
[Code]....
But image never is changed. So I think something wrong with ChangeImage().
I have an ASP.NET (3.5) web page which calls a few web methods (SOAP based) using jQuery's .ajax method. The web methods implement 'ScriptMethod' attribute and return JSON data. The web service file (asmx) is local to the same project.
I noticed these web methods execute synchronously on the server which means they run sequentially and affect performance negatively, some methods are waiting, when some of them are slow.
I read this article and I am not sure if I understand that WebMethods which implement Scriptmethod can run synchronously only (they implement IHttpHandler not IHttpAsyncHandler).
If this is true, I might have to change the design. I am looking for other designs, maybe like using WCF, where the browser can call webmethods using JavaScript and the web methods run asynchronously on the server.
I have a C# ASP.NET MVC application which has been using jquery 1.3.2 in VS2008 environment.
I decided to upgrade to 1.4.2 and added the file to my project. Changed the reference in my masterpage header to the new version. But now nothing works, it's like it can't find the jquery library.
I am new to programming especially jQuery and webservices. I want to pass the values to the to database via the webservice. Below is the code for the .aspx page:
I have two project both on same machin under same solution.One is my webservice and another inculde my webproject that access that webservice using jquery .I am using flexigrid control to populate my data.it is working fine when i am trying to use the webservice on my machin under same solution but when i try to use webservice reside on another machin it not working for me. This is my aspx page
[Code]....
when i chage the [URL] from to this [URL] it is not giving the same result as that of previous url.why it is not working i am not gettting it. I m not getting why it is happing so.
I'm breaking my head over this for a while now and I have no clue what I do wrong. The scenario is as followed, I'm using swfupload to upload files with a progressbar via a webservice. the webservice needs to return the name of the generated thumbnail. This all goes well and though i prefer to get the returned data in json (might change it later in the swfupload js files) the default xml data is fine too.
So when an upload completes the webservice returns the following xml as expected (note I removed the namespace in webservice):
Now I want to parse this result with jquery and thought the following would do it:
var xml = response; alert($(xml).find("string").text());
But I cannot get the string value. I've tried lots of combinations (.html(), .innerhtml(), response.find("string").text() but nothing seems to work. This is my first time trying to parse xml via jquery so maybe I'm doing something fundemantally wrong. The 'response' is populated with the xml.
$('#' + textboxID).autocomplete({ delay: delay, source: ["cats", "dogs"] }); which works fine. I want to use a webservice: $('#' + textboxID).autocomplete({ delay: delay, source: webserviceURL}); This doesn't work. My webservice URL is /blah/blah.asmx/myMethod The webservice definition is: [WebMethod] [ScriptMethod(ResponseFormat = ResponseFormat.Json)] public List<string> myMethod(string term) { // Logic here, return list of strings }
The method never gets called. Can anyone point me in the right direction? I have other webservices in the same .asmx which work fine with other controls (other controls are using $.ajax to call them).
Edit: Getting closer, I now get a 500 error saying Request format is unrecognized for URL unexpectedly ending in '/myMethod'. I think it's not treating my url quite right..
I need to pass a customer id to get some data back for a customer from a webservice. I can't figure out how to get to the webservice, I have a breakpoint set in the webmethod but it's not being hit and the alert box is not popping up either. For a test I am just trying to show some value from the returned data in an alert box. Note I am just hard coding the customer id of 1001. The webmethod takes a parameter of string customerid.
[Code]....
Does some one know what's missing or how to debug this issue?
I'm generating a file on the server which takes some time. For this, I have a hidden iframe which I then set the .src attribute to an aspx file i.e iframe.src = "/downloadFile.aspx"While this is taking place, I'd like to have a call to a web service return the progress. To do this, I thought I could use window.setInterval or window.setTimeout but Javascript seems to be blocked as soon as I set the iframe src attribute.Does anyone know how to get around this or perhaps try a different approach?I have also tried handlers, but the request never gets to the server so I'm assuming is a browser/javascript issue.
//Function that gets the file function GetFile() { setTimeout(GetProgress, 1000); var iframe = document.createElement("iframe");
