Javascript - Running A JS Method On Load From Code Behind?
Mar 10, 2011
I am trying to load the following JS method:
<script type="text/javascript">
function initialize(lon,lat) {
var myLatlng = new google.maps.LatLng(lon,lan);
var myOptions = {
zoom: 14,
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
var map = new google.maps.Map(document.getElementById("map"), myOptions);
var marker = new google.maps.Marker({
position: myLatlng,
map: map
});
}
</script>
In my code behind in VB.NET I then want to load such as:
I have a piece of inline java script which is within an AJAX updatepanel. The code works perfectly on 1st load but not when the updatepanel is updated.
i have a popup that is getting displayed when Save button is clicked. The popup has 2 buttons. Yes and No. No should cancel the popupand yes should take you to function in the code-behind say, btnSave_Click(object sender, Eventargs e). How is it possible.
I want execute below callback() method after completion of document.getElementById('btnDownload').click(); method . Now callback()executing immediatly. I want wait "Click()" process done then Execute callback(); method.
function LoadPopup() { // find the popup behavior this._popup = $find('mdlPopup'); // show the popup this._popup.show(); // synchronously run the server side validation ... document.getElementById('btnDownload').click(); callback(); } function callback() { this._popup = $find('mdlPopup'); // hide the popup this._popup.hide(); alert("hi"); }
[System.Web.Services.WebMethod] public static string GetStateData(string state) { //this is where i want to call a javascript method "GetItems" }
I have a javascript method that retrieves some values for me and I want to get use one of those values in my web method
function GetItems() { var variable1= $("#<%=Item1.ClientID %> input:checked"); var variable2= $("#<%=Item2.ClientID %>").val(); return [variable1.text(), variable2.val(), variable2];}
I've searched for ways to call the javascript method from the web method but every time my search results in how to call a web method from javascript.
I did find this but it was done from the code-behind of a silverlight project and when I tried adding the correct reference to my code-behind it wasn't there
var result = HtmlPage.Window.Invoke("GetItems"); Is there a reference I'm missing?
How can I call a .net method in inline code using a javascript variable?My code looks like this:
for ( var i = 0; i < numberIterations; i++ ) { var result = <%# GetFilterTagURL( myArray[i].Value, false) %>; //do stuff with result }
This block is inside a javascript block; the GetFilterTagURL method is a a .net method and I want to pass the variable myArray[i].Value as the first parameter.
UPDATE:I guess that, as you say, I'll have to create a web service to achieve what I want.
I have an ASP.NET page and have a couple of linkbuttons and Iframes. The pages in side of these IFrame take long time to load, I want the user to navigate to another page by clicking one of the linkbuttons. Now, it looks like it is waiting for the the iframes to finish loading when i click on a link button, the page is still trying to load (instead of navigating to different page).
Is there any way I can stop the iframes to load and go to another page?
I have a java script function which presents a countdown timer.when the timer reaches zero, I want to somehow activate a function on the server side in the code-behind.I understand it is impossible to directly call a server-side function, but is there a simple way to still fire it?I want to fire the (event-handler) code behind function: protected void ButtonFinish_Click(object sender, EventArgs e).
var _countDowncontainer = 0; var _currentSeconds = 0; function ActivateCountDown(strContainerID, initialValue) { _countDowncontainer = document.getElementById(strContainerID); [code]...
I want to call a javascript method during page load. I am using application.master of the sharepoint server 2007 as the master page . In the content page i want to call a custom method named OnLoadFun() during loading the content page. I have written the function inside script tag in the PlaceHolderAdditionalPageHead id section of the content page.
[Code]....
How do i call the OnLoadFun method so the i is being called onload time. i tried putting window.onload=OnLoadFun surrounded by script tag within the PlaceHolderMain content section.
I'm building this small control. It should detect client resolution and set height and width values within two separated HtmlInputHidden controls. But tester property is not getting values froms this control.
[ToolboxData("<{0}:UIControlResolution runat=server></{0}:UIControlResolution>")] public class UIControlResolution : Control { HtmlInputHidden _txtwidth = new HtmlInputHidden(); HtmlInputHidden _txtheight = new HtmlInputHidden();
I have an application that has JS calling ASMX files to do asyncronous requests, using ASP.NET AJAX.
The problem is that I use always the same "onError" function, and now I don't know how to identify the method that rised the error, and it is giving me a lot of problems to debug errors. The parameter "data" of the onError method does not give enough information, for example:
en System.ComponentModel.BaseNumberConverter.ConvertFrom(ITypeDescriptorContext context, CultureInfo culture, Object value) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeInternal(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToTypeMain(Object o, Type type, JavaScriptSerializer serializer, Boolean throwOnError, Object& convertedObject) en System.Web.Script.Serialization.ObjectConverter.ConvertObjectToType(Object o, Type type, JavaScriptSerializer serializer) en System.Web.Script.Services.WebServiceMethodData.StrongTypeParameters(IDictionary`2 rawParams) en System.Web.Script.Services.WebServiceMethodData.CallMethodFromRawParams(Object target, IDictionary`2 parameters) en System.Web.Script.Services.RestHandler.InvokeMethod(HttpContext context, WebServiceMethodData methodData, IDictionary`2 rawParams) en System.Web.Script.Services.RestHandler.ExecuteWebServiceCall(HttpContext context, WebServiceMethodData methodData)
Is there any way to know the webmethod that raised the error?
I have had a project called Articles and the project complies fine. I have it running as a seperate site on my machine and it works like a charm under IIS7. When I start the project from VS2010 in debug mode (by pressing F5) it lands on a page that says: "Parser Error Message: Could not load type 'Articles._Default'."
I i however change the path in the browser from [URL] Home it works fine again, indicating that my routing table is bust but it was working yesterday and I did not change any route, The error page also says: "Please do not delete this file. It is used to ensure that ASP.NET MVC is activated by IIS when a user makes a "/" request to the server." That idicates to me that it went to default.aspx...right?
Im using 3 image buttons on a web page, and the buttons, (its either one or two) , will not load when i run it. and i have to close the browser and run it again. theres a 50-50 chance that the buttons will actually appear. Any idea what's causing this to happen? The pictures are in png format. and i saw from this website that I should change "Causes Validation" to false? What does it mean? Image buttons (from left to right):
Reigster - Back - Reset.
On my login page, i only have one image button which is Login and its always there. btw, im using visual studio 2005 =)
I'm working on an ASP.net web application. I'm getting errors on some of my pages where I get runtime JavaScript errors. I've narrowed the problem down to a single ASP Menu control on the master page. I created a blank page with just the ASP Menu control. The ASP Menu control is bound to Web.sitemap. The page intermittently gives runtime errors. However, if I refresh the page, the error may or may not appear on any given page load. Sometimes, it works; sometimes, the browser throws runtime errors when loading the page or when I mouse over the ASP Menu control.
When I catch the error in Visual Studio, the message is "microsoft jscript runtime error 'sys' is undefined". When I Google for this message, I find that it is usually associated with AJAX. However, the ONLY thing on the page is a single ASP control. There is absolutely no Javascript on the page except for what gets generated by the .net framework. What could be causing this problem? UPDATE I've found out that my environment actually has load balancing with a web farm of three servers servicing the URL. When I access the application on any one of the servers individually by IP address, everything works fine.
To clarify, I understand that when a user hits the public-facing URL, it resolves to x.x.x.1. x.x.x.1 is the address for a switch which routes the request to either x.x.x.2, x.x.x.3, or x.x.x.4. When I use the public-facing URL, I find that some of the axd file requests are intermittently rerouted to Error.aspx! WTF? I'm told that this is the result of a security feature that is meant to protect me from cross-site scripting and other assorted bad stuff. What can I do? Update After taking out some error page auto-redirects, I get a more meaningful error message: ASP.NET Ajax client-side framework failed to load.

I want to disable this script for twitter widget to be displayed on some pages. How can I access the script from the backend and change the url on runtime?
We have a timer process (a JQuery plugin) that redirects after X number of minutes to the login page, all via JavaScript. When the timer hits zero, I want to run a task (could be anything; however, in this specific scenario, it's a web service call).
The issue I'm having is the web service that runs with the finish-up processes is not being called. The web service call happens, the redirect happens, I don't see any errors (I have try/catch statements around the setTimeout call), but no WS call.
In my ASP.Net 2008 app I've got a page that uses a Master Page and I want to use jquery/javascript but I can't even get this simple code to work. the page loads and controls display but no alert.
