• ValidatorEnable is not defined when rolled with AJAX

  - by tigermain

  I have some webforms which have been working fine with various static and dynamically generated validators. For some reason now that I have implemented UpdatePanels on the forms, when I manually call the ValidatorEnable() method on one of them (when I click a checkbox) I get the "ValidatorEnable is not defined" error message. I am passing the same clientID etc into the method that I was using before I implemented the AJAX.net controls It would seem .net isnt rendering the /WebResource.axd?d=aUu4P3dfjWWyw3KQ9t2ZdqxnzYhrtq9uWWiRZduXE-g1 script to the page, adding it manually I get other missing JS objects. So how can I force it to register the relevant scripts? N.B. The validators in question are being rendered in a repeater

• jQuery Address Plugin - Not allowing loading ajax?

  - by Nic Hubbard

  I am trying to test the jQuery Address Plugin and it seems to not allow ajax to work in the change function. I am using: $.address.change(function(event) { $('#content').load(event.value+' #content'); $.address.title(event.value); }); $('a').click(function() { $.address.value($(this).attr('href')); }); While I can use event.value for other things, it just does not seem to let the .load() function work. Even trying a static URL in .load() does nothing. Is something in the plugin preventing this? I thought this was the point of the plugin!

  I'm writing a VB.net program for a website that uses the AJAX Lits options http://www.ajaxdaddy.com/demo-dhtml-autocomplete.html Whats more is that the website has used additional arguments in the function that i'm not exactly sure what they are calling, and there a trigger that executes an action that must be click, tabbing and returning fail.

• Ajax method call

  - by LooDaFunk

  Hi, I am trying to call a simple method in my code behind using Jquery with Ajax. But I get a 404 not found exception everytime. Unfortunately this is a web forms solution. So I dont have all the perks of MVC :( It does get into the javascript method and gives the alert but won't go into my c# method. My previous experience of using this Jquery method is in an MVC website. Is it compatible with webforms sites? Here is the code: http://pastebin.com/Xdey4XTS Thanks Merry Christmas!

  - by Stevie Jenowski

  Hello! First and foremost thank you for checking out my problem, and for any help you may give! Okay, so like the title says I'm in need of calling a php function from my index page, which adds a new record in my database as a vote, using JQuery Ajax.

• Ajax: Load XML from different domain?

  - by John Isaacks

  I have signed up(paid) for Google site search. They have me a url of a sort of web service where I can send a query to it, it searches my site, and it returns XML of the search results. Well I am trying to load this XML via Ajax from a page on my site but I cannot. I can load from any of my pages on my domain so I am assuming it is because of the XML being on Google's domain. So there has got to be a way to load it though, I don't think they would have given me the URL if I couldn't do anything with it lol. Does anyone know how to do this? Thanks! UPDATE: this is what the page says on google that gave me the XML: How to get XML You can get XML results for your search engine by replacing query+terms with your search query in this URL: http://www.google.com/cse?cx=MY_UNIQUE_KEY&client=google-csbe&output=xml_no_dtd&q=query+terms Where MY_UNIQUE_KEY = my unique key.

• Jquery Ajax loading Problem

  - by Starx

  I have a function to load a html part into a element in main index page kinda like this $(".ajax").click(function() { //load a page into a element }); This works But the HTML part which i have just loaded also have links that need to trigger same function above, but it does not. Until I save that function in a separate .js file and load in the main index file as well as all other files from where I need to trigger that function even though these internal files are going to loaded into the the first main file . Is there any way for a function in the index file to run from the html document that is loaded inside a element.

• Ajax security problem

  - by coolboycsaba

  I want to create a browser based game and I have a huge problem, the game can be easily hacked. The problem is at a page where you can go to "work", I store in a file the work ending date and the amount of money what you will receive after finishing the work. There are 4 type of works. The problem is that I use ajax to send to a php file the necessary information. The URL looks like this x.php?date=....&pay=.... The javascript part of the page calculates the date and the pay but if you simply enter in your URL bar x.php?date=anynumber&pay=99999 you will receive that 99999 dollars. What should I do ? And sorry for my bad english :)

• why won't my ajax work asynchronously

  - by payling

  I'm having trouble understanding why my code will not work asynchronously. When running asynchronously the get_price.php always receives the same $_GET value even though the alert before outputs a unique $_GET value. var arraySize = "<? echo count($_SESSION['items']); ?>"; //get items count var pos = 0; var pid; var qty; getPriceAjax(); function getPriceAjax() { pid = document.cartItemForm.elements[pos].id; //product id qty = document.cartItemForm.elements[pos].value; //quantity alert('Product: ' + pid + ' Quantity: ' + qty); $.ajax({ url:"includes/ajax_php/get_price.php", type:"GET", data:'pid='+pid+'&qty='+qty, async:true, cache:false, success:function(data){ while(pos < arraySize) { document.getElementById(pid + 'result').innerHTML=data; pos++; getPriceAjax(); } } }) }

• jQuery-ajax call: async property is not working?

  - by user269386

  Hi, given to certain circumstances, I'm forced to keep page settings (Javascript-values) in the session and it has to be done right before leaving the page (I can't use cookies, since "pageSettings" can become quite large and localStorage is not an option yet ;) ). So this is how I tried it. However it seems that when I call the page directly again, the call of "http://blabla.com/bla" happens asynchronous, even though the async-attribute is set (I don't receive the settings of the previous call, but of the one before): $jQ(document).ready(function () { $jQ(window).unload(Main.__setSessionValues); }); var Main = { pageSettings: {}, __setSessionValues: function __setSessionValues() { $jQ.ajax({ type: "POST", async: false, url: "http://blabla.com/bla", data: { pageSettings: Object.toJSON(Main.pageSettings) } }); } }; Does anyone know what the problem might be? thanks in advance

• Show friendly message on ASP.NET Ajax error

  - by balexandre

  You all know how annoying is this: I do have a log system and the correct error is well explicit there, but I want to give a better message to the user. I keep trying several ways but I'm using Telerik components and well jQuery and I ended up using both ASP.NET Ajax methods and jQuery, so I use function pageLoad() { try { var manager = Sys.WebForms.PageRequestManager.getInstance(); manager.add_endRequest(endRequest); manager.add_beginRequest(OnBeginRequest); manager } catch (err) { alert(err); } } as well $(document).ready(function() { ... } that alert(err) is never fired even upon OnClick events what's the best approach to avoid this message errors and provide a cleaner way? all this happens in <asp:UpdatePanel> as I use that when I didn't know better (3 years ago!) and I really don't want to mess up and build all again from scratch :( Any help is greatly appreciated Updated with more error windows after volpav solution

• ASP.NET Ajax Error: Sys.WebForms.PageRequestManagerParserErrorException

  - by Phil Bennett

  My website has been giving me intermittent errors when trying to perform any Ajax activities. The message I get is Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled. Details: Error parsing near ' So its obviously some sort of server timeout or the server's just returning back mangled garbage. This generally, unfortunately not always, happens when the site has been idle for a while. Anybody else been able to overcome this? Thanks

• ajax page works in development (vs2010) but does a full postback on production win2k8R2

  - by merk

  Hi all, I have a stupid simple page. I've got a panel and a button. Clicking the button either hides or displays the panel. That much works. I added in a script manager control and update panel - put all the page contents in the updatepanel/contenttemplate When i run this under vs2010 and click the button, the page does NOT post back - the panel just appears or disappears without the whole page refreshing, which is what i wanted. I upload this to my IIS7.5 server and the page is posting back/whole page is refreshing when i click the button. Do i need to configure anything on the server to enable ajax? thanks

• jQuery AJAX & Multiple sp Result Sets

  - by Kevin

  Is it possible to use a stored procedure that returns multiple result sets in json format and process them as part of one request using ajax calls in jquery? In other words, I have a stored procedure that returns several result sets that are to be used with a series of select boxes that are all being filtered by the same criteria. If any of the select boxes is chosen that value is then passed to the stored procedure and all the subsequent select box updates reflect only results that match the filtered criteria. I don't want to have to call the same sp multiple times to process the results and was trying not to create multiple queries, so I'm wondering if it's possible to store more than one json result in a single request and then store and process them on the client side.

• Resolve HTTP 304 - not modified in AJAX call made via GWT

  - by Salvin Francis

  We are using an application made in GWT with the server as tomcat. The project runs fine normally, however there are situations where the server is restarted. At such point of time, the ajax call made by the code below returns blank text with the status code as 304 RequestBuilder requestBuilder = new RequestBuilder(RequestBuilder.POST, URL.encode(serverUrl)); //-- serverUrl is the url to which this call is posted to. requestBuilder.setHeader("Content-Type", "application/x-www-form-urlencoded"); requestBuilder.setHeader("Expires","0"); requestBuilder.sendRequest( postData, new RequestCallback() { public void onError(Request request, Throwable exception) { //Do nothing } public void onResponseReceived(Request request, Response response) { //sometimes when the server is restarted, I get response.getStatusCode() = 304 and the response.getText() as blank } } ); normally we get back some data from the server inside this response text. How do we now get the data when the response itself is blank ?

• Problems using jQuery $.ajax to pass data

  - by iboeno

  I'm using ASP.NET and attempting to call a method with a signature of [WebMethod] public static string GetInfo(string id){...} using the following javascript: var elementValue = $("#element").attr('id'); var d = "{id : " + elementValue + "}"; $.ajax({ type: "POST", url: "../WebPage.aspx/GetInfo", data: d, contentType: "application/json; charset=utf-8", dataType: "json", success: function(msg) { //do this } }); And this is not working. If instead I set elementValue = 2; it works fine. If I try to hardcode in a string value for testing purposes e.g. elementValue = "nameToLookUp"; It fails. Why is this happening, and how do I resolve it? On a side not, why is type: required to be POST instead of a GET? In the end I just want to pass a string value I want to look up in a DB and retrieving some json data.
