问题 My Pagemethod implementation is not working in Chrome browser. I have ASP.NET 3.5 web application developed in VS 2008.

问题 jQuery 1.3.2, ASP.NET 2.0. Making an AJAX call to a PageMethod (WebMethod) returns the full/whole page instead of just the response. A breakpoint on the page method shows it's never getting hit. I have the [WebMethod] attribute on my method, and it is public static, returns string and accepts no params. I even tried adding [ScriptService] at the top of my class to see if it helped, but it did not. I have seen this post Jquery AJAX with ASP.NET WebMethod Returning Entire Page which had my same

问题 Is it possible to call a function on the server side from the client side using PageMethods , and access that function's return value in JavaScript?

问题 ASP.NET 2.0, PageMethods. Good day, I'm using ASP.NET AJAX PageMethods to dynamically change the text of a Label when a dropdownlist is changed on my page. I know that the text of Labels are not retained between postbacks when they are changed on client-side, which is my case. I've heard that a solution is to keep the label content in a hidden field, then to set Label text from that field in Page_Load. However, this solution does not seem really clean to me. Are there any other alternatives

问题 I'm trying to do this: function DelBatch() {var userInfo = get_cookie("UserInfo"); PageMethods.DeleteBatchJSWM(userInfo, function(result) {window.location = "BatchOperations.aspx";}); } But it still runs asynchronously. I need the browser to actually wait until my code-behind is finished executing, then it can be refreshed There's a listbox loaded with values that were just deleted from the database, they shouldn't be visible. Problem I have is the window location refreshes before the code

问题 I am performing a jQuery .ajax() call that returns a List<string> of IP addresses on a specified subnet. I use a [WebMethod] on an .aspx page to return the values. ASP.NET's built-in JSON serializer does the magic to return the actual JSON used in my Javascript. I have profiled the the server-side time, and it takes about 8 msec to populate and return the list, so the server-side code is not the issue. However, when the Ajax call is initiated, in Internet Explorer it can take upwards of 3

问题 The pagemethod works, however when I use the webmethod it refreshes the page destroying the reason to use angular 2 in the first place. How do I prevent the form from refreshing the page? index.aspx <body> <form id="form1" runat="server"> <asp:ScriptManager ID="ScriptManagerMain" runat="server" EnablePageMethods="true" > </asp:ScriptManager> <my-app>Loading...</my-app> </form> </body> index.aspx.cs [WebMethod] public static string getString() { return "Test"; } app.component.html <div>
