AJAX :: Webservice Call From Javascript Fails If Masterpage In Force?
Mar 2, 2010
I am calling a web service via Javascript. I tried it first in a web page that does not have a Masterpage and it worked perfectly. Then I moved everything over to a web page that does use a Masterpage, and I get a "Microsoft JScript runtime error: Object required" on the javascript statement that calls the web service. My javascript statements look like so:
I'm calling a web service called GetTooltip from inside Javascript. However, since the web service is called asynchronously, it doesn't wait until I get the return value from the web service, before it continues again. This is a bit of a problem for me, since the web service is in a for-loop. How do I make the Javascript wait until I hear back from the web service, before letting Javascript continue the for-loop?
I'm calling a webservice using jQuery with .ajaxHere are the data parameters for the call:
var parameters = "{'Titre':'" + Titre + "','Description':'" + Description + "','Contact':'" + Contact + "','VilleId':'" + VilleId + "','QuartierId':'" + QuartierId + "','UserId':'" + UserId + "'}"; It works fine. But when parameters Description or Titre contain the ' character , no call!!!
Does anyone have an idea how can i make it work even with apostrophe character in Titre and/or Description?

But i am getting Sim is not defined. Error. post ur comments. I have reviewed most of the forums. I am not able to clear
I have a web user control. That I load dynamicaly inside a modalpopup window using dynamic populate extender. User control has a external javascript file linked to it. Problem: I cannot make call to webservice method from this external javascript file. When I make a call -- servicename.methodname() I get servicename not defined error.
Pinging back to a webservice in ajax from the client keeps the user's session alive, I don't want this to happen. More extensive summary For a website we're developing, we need the client to ping back (in js) to a webservice (ASMX) on the server (IIS7.5). This happens to let the server know that the user is still on the site, and hasn't browsed away to another site. This is as our customer wants to let users lock records, but if they browse away to other sites, then let other people take over those locked records. Perhaps the distinction between the client being on the site but inactive and on another site seems unimportant, but that's kinda irrelevant, I don't get to write the UI spec, I just have to make it work.
My problem is this, the ping stops the user from being timed out on the server through the standard forms authentication timeout mechanism. Not surprising as there is that 30 second ping in the background keeping the session alive. Even though we want to know if the user is still on the site, we want the normal forms authentication timeout mechanism to be honoured. I thought I might be able to fix this by removing the ASP.NET_SessionId and .ASPXAUTH cookies in the XMLHttpRequest that is the server ping, but I can't figure out how to do this. This is how my web service & method are defined:
[WebService(Namespace = "http://tempuri.org/")] [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)] [ScriptService] public class PingWS : WebService { [WebMethod] public void SessionActive(string sessionID) { // does stuff here } This is how I'm calling it in js (request is over HTTPS, : $.ajax({ type: "POST", url: "PingWS.asmx/SessionActive", data: 'sessionID=' + aspSessionID + '}', beforeSend: function (xhr) { xhr.setRequestHeader('Cookie', ''); xhr.setRequestHeader('Cookie', 'ASP.NET_SessionId=aaa; .ASPXAUTH=bbb;'); }, dataType: "json" });
I was trying with the setRequestHeader, but that just appends to the header rather than overwrites the header, and IIS is happy to ignore that junk I added. I'm thinking maybe I should be trying to do this at the server end, someone take PingWS.asmx out of the loop so that it doesn't keep the session active, but I'm not sure how to do this. Although the title of the question is focused on clearing the cookie in the header, I'd be super happy if anyone points out that I'm being really stupid and there is actually a much better way of trying to do what I'm doing.
I'm thinking at this stage maybe I need to add something to the webmethod that says how long this particular page has been inactive, and use that knowledge to timeout manually. That actually sounds pretty easy, so I think I'll do that for now. I'm still convinced that there must be an easy way to do what I originally wanted to do though. Update I'm thinking I'm pretty screwed in terms of cookie manipulation here as both the .ASPXAUTH and ASP.NETSessionId cookie are HttpOnly, which means the browser takes them out of your hands, you can't access them via the document.cookies object. So I would say that leaves me with:
Updating my SessionAlive webmethod to track each request so I can tell how long the user has been sitting idle on a page and timeout if needs be Marking the .asmx page somehow on the server end so that it's taken out of the normal authentication/session tracking flow I know how to do 1. so I'll start there but 2. seems much cleaner to me.
In IIS I have a virtual directory with only windows authentication enabled. From Javascript I call into a ASMX webservice. From the ASMX webservice I make a call to the SharePoint Search.asmx Webservice. whatever I try I keep getting the followin gerror message:
"The request failed with HTTP status 401: Unauthorized"
I use the following code to call the SharePoint webservice
[Code]....
My web.config settings are:
[Code]....
The Sharepoint farm is configured to use NTLM authentication.
Strangely everything works when I am testing in Visual Studio using the builtin webservice, but when I deply to my local IIS or Test Server it breaks.
I'm doing a project in asp.net with a web services. My web services and my asp.net project is separate and my asp.net projet have a reference of my web services. i'm using visual studio 2008 framework 3.5 and my service web is in vb.net. i want to call the web methods of my web services in javascript my script manager is declared
service1 is the class of my Webservice and i call the function test with my button <input name="btnRecherche" class="btnRechercher" type="button" value="Rechercher un emplacement" onclick="test()" /> the problem is : JavaScript say Service1 is not defined but why .... What's the problem ? I've checked many forums and videos every body did it sorry for the french variable
all My web app is calling webservice which resides in same virtuall directory as web app . In this scenario i have a javascript function like this which works perfectly.
My javascript code is calling a asp.net webservice, so i have a call to the webservice something like this:MyWebservice.GetData(param, ResponseReceived, ResponseTimeOut, ResponseError);When the webservice returns data, ResponseReceived method is called.However sometimes the user might navigate to another url before the webservice call actually returns, in such a scenario FireFox throws an Error saying 'An error occured oricessubg the request. The server method GetData failed'So my question is how can i kill the async call when the user navigates to another page or makes another request to the webservice? I know in a normal XMLHttpRequest i could have called Abort method, but not sure how to make it work with the above webservice proxy.
I've got a click tracking AJAX function (calls a WebMethod on an .aspx page), and I need to call it when the user clicks through to a link.Unfortunately, I'm using window.location = "newUrl" to change the page, which seems to make the AJAX call fail. Is there a way around this?I do not need to get any information back from the AJAX call, I just need to make sure the WebMethod is called'm aware that I could just redirect on the success() or failure() calls, but then I would have to wait for the clickTracking() method to run, which takes ~ 1s. That is not acceptable by the agreement in the project spec, and so is not a viable solution.
Is there a simple way to turn off form submit behaviour of the page when ENTER is pressed while I am focused to textbox? What I want to achieve is to call a web-service without submiting the page when ENTER is pressed in a specific textbox in my aspx page?
I am getting a JSON object from a webMethod by the call below and I set some textBox values based on the returned objects attributes.Problem is, just for a moment my textBoxes are populated but then immidiately they return back to empty.Do I make a mistake or I cannot make DOM elements modifications within a success function?
I have am trying to implement a simple AutoComplete function yet i am having difficulty. It looks like the AutoComplete control is not even calling the method (webservice). If i load the webservice from the browser, i can see my Method, click on it, enter in the prefix, click on Invoke and it returns a SQL STRING. Below is the string the webservice returns.
I have a webservice "DataService.asmx" which I am using for AJAX calls for insert, update, delete and some other tasks. All the pages are calling webservice smoothly but this new page I added and calling my webservice using the same ajax method not working. Strange thing is that neither its going on SUCCESS nor FAILURE...and put a breakpoint on my webservice but its not going into the webservice...plz help as its been 6 hours now figuring what the problem is..here is the code.
I am looking to incorporate web service into my application but am running into a problem. The following line of code in FwkComm.js document generates the following error: Microsoft JScript runtime error: 'FwkService' is undefined.
On one of my pages I've got a popup window implemented using the ModalPopupExtender. The content html of the popup is retrieved from a webservice dynamically (using DynamicServicePath, DynamicServiceMethod properties of the extender). Everything works fine, however there is a minor problem: web service call takes about 2 seconds and the popup panel is blank during this time, which confuses the users. I would like to display 'Loading...' message in the popup window (or an animated image, does not really matter) during the webservice call. Is there a way to do it?
in fact I have 2 webservice calls, one returns 8 results and the other one 4 results. So the same webservice is called twice but with different arguments and on different pages(browsers).What happens? even though I call on one page only one webservice(arguments1), I also get the results from webservicearguments2) which should be only on PAGE2to be more clear: I get both webservice results in both the pages, when I expect one for each page, it's like they share webservice results somehow,
I have written code to access a text file in another server from my application in javascript. This code works fine in IE but fails in mozilla firefox. Below is the code i have written.
var httpRequest; httpRequest = new XMLHttpRequest(); httpRequest.open('GET', url, true); httpRequest.setRequestHeader('X-PINGOTHER','pingpong'); httpRequest.setRequestHeader('Content-Type','application/plain'); httpRequest.onreadystatechange = function() {alertContents(httpRequest); httpRequest.send(''); function alertContents(httpRequest){ if (httpRequest.readystate == 4){ if (httpRequest.status == 200) { alert(httpRequest.responseText); } } }
I am planning to use a Javascript call to a WebService to retrieve data from the database. At the moment I am using Ajax to do this. But since the Ajax is slowing down the performance of my application. I have read in some article that even though Ajax only refreshes the Update panel contents, Ajax does a full round trip to the server. What I need to know is how can I populate a Grid from data coming from a WebService via a Javascript call.
does anyone have any working code that uses javascript to open and close a cpe when the CPE is in a masterpage? It seems like the javascript never is able to find the CPE when it is on a master page. I have an DropDownList on the page and when certain items are selected, i want to collapse or expand when others are selected. It seems to work fine on a regular page, but not when it is a page nested in a master page. It is adding a suffix to the CPE and javascript is unable to find it.
