asp.net-ajax

问题 I have a webforms app that uses a few ASP.NET AJAX Timer controls (i.e. polling). If a user is on a page with one of these, they will effectively never time-out, as the polling process keeps their authentication ticket alive. I'd like to segment Timer controls so they don't trigger Forms Authentication's RenewTicketIfOld method. The path I'm on and I've done something similar before is to inject something into the AJAX HTTP request to have these requests identified as coming from a timer and

问题 I know there's an easy answer to this, but this comes in the form of 2 problems. Problem 1: In an asp.net page there is a javascript block like this: <script type="text/javascript"> function doSomethingRandom() { var myVarToUse = <asp:Literal runat="server" ID="HackyLiteral" /> } </script> Ok, so it's a simplified version of the problem, but it should be clear. I now want to move this function in to a JS file...but I can't get the asp:Literal into the JS. var myVarToUse = <asp:Literal runat=

问题 Does there exist a solution for this scenario? I have a content page which contains an UpdatePanel and has a combobox. When the combobox value is changed I want to change a label in my Master page. So, the main problem for me is that I don't want to make a full postback with every combobox value changing. Is there some trick to overcome full postback? Thanks in advance. 回答1: Put your label in your MasterPage in a separate UpdatePanel. On dropdownlist's SelectedIndexChange make an asnychronous

问题 I'm new to Asp MVC, and I'm trying to accomplish a little async update (I'm using MVC3 RC2, with Razor, but I can manage with ASPX solutions too). I have a Master page, which renders a shopping cart box on every page by calling Html.RenderAction("Cart","Shop"). The Cart action of the ShopController calls the database, etc, and outputs the results. This works. First problem: if I put an ActionLink in this partial view (like Html.ActionLink("Remove")), then even if I call PartialView() from the

问题 I want to do AJAX POST in my MVC View. I've written the following: Script Code in View $('#media-search').click(function () { var data = { key: $('#search-query').val() }; $.ajax({ type: 'POST', url: '/Builder/Search', data: JSON.stringify(data), dataType: 'json', contentType: 'application/json; charset=utf-8', success: function (data) { $('.builder').empty(); alert("Key Passed Successfully!!!"); } }); }); Controller Code [HttpPost] public ActionResult Search(string key) { return

问题 I am trying to figure out what is wrong with the following code: $(".ReportScore").click(function () { $.ajax({ type: "GET", url: "/events/Tournaments/ReportScore", success: function() { location.reload(); }, error: function() { alert("The scores were not recorded"); } }); }); When I type the url in the bar, it works without problems, however when I try to do an ajax call I get 404 Page not found error. To clarify, when I click on the button I Get a popup saying "The scores were not recorded"

问题 I'm using AJAX.Net (3.5) inside a usercontrol. The usercontrol contains an UpdatePanel, and inside the UpdatePanelthere is a MultiView. The ScriptManager is included in the page that act as container for the usercontrol. To switch between views the usercontrol contains a simple button. When I click it, the View is changed so the old content is hidden and new content is displayed. My problem is that the content isn't hidden at all. The view changes and the new content is displayed, but the old

问题 I am looking at an asp.net 2 web application that I am maintaining (but did not write). Some things that should happen on the page loading do not, but only sometimes, and it seems to be if you are using Firefox 3 inside a VM. JQuery and asp.net Ajax are used. The important function that should run every time (but does not) is attached by the following Javascript: <script type="text/javascript"> //<![CDATA[ $(document).ready(function(){ Sys.Application.add_load(ImportantFunction); }); $
