Getting error calling Javsscript function from another Javascript function
[Code]....
I am getting an error while calling a javascript from a dropdownlist which is placed inside a modal pop-up panel. if i am ebeding a small script like onchange="javascript:alert('hello');", it works fine. But if i m using <script> </script> for embeding a javascript its showing 'object doesn't support this property' error. when i debugged it the compiler does not get into the javascript function.
Below is a screenshot of that page.
$.ajax(
{
type: "POST",
url: "Default.aspx/GetAge",
data: "{}",[code]...
Right now it reports the following error: "Cannot locate the resource". I figure that I am specifying the url incorrectly. This javascript is in an external file located in the same directory as Default.aspx .
I have a Site.Master in my ASP.NET project which defines a HEAD section as follows
<head runat="server">
<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" />
<title id="MasterTitle">MyApp</title>
<link rel="icon" href="Content/icon.ico" type="image/x-icon" />
<link href="Content/mycss.css" rel="stylesheet" type="text/css" />
<script src="Content/mycode.js" type="text/javascript"></script>
</head>
In the mycode.js file, I have a function called GetSels();
function GetSels()
{
//do stuff
}
If the GetSels function is defined in Site.Master, GetSels is callable. If it's in mycode.js, it's not. Every code example I've seen seems to say this should work.

View 3 Repliesi wanted to show or hide duplicate records according to query. So, I need to know how to call the javscript function from C# codebehind.
<a onclick="Grid1.insertRecord(); return false;" id="a2" href="javascript:">Save</a>
When I click save i need to show a popup which i Have written in javascript.
if (!exist)//exists is the query
{
System.Web.UI.Control my = FindControl("a2");
a2.Attributes.Add("onclick", "retrun HideDuplicate()");
This line returns an error saying "a2 doesnot exist in current context."
how to call a partial view from within a Javascript function? I've looked around the web, but all the examples that I have been able to find are examples using Ajax.ActionLink or Ajax.BeginForm.
When a user clicks on an item, I want to be able to hide/display some Divs and possible do other operations before calling the partial view. ActionLink doesn't appear to provide that ability. Depending upon the item the user clicked, I may be assigning the results of the PartialView to the same Div, or to a different Div.
What I'm looking to achieve, is to have an onclick handler associated with the item which performs whatever other operations might need to be done, then assign the result of the call of the PartialView to the appropiate Div. In some instances, the function might even be making two separate calls to PartialViews, to update the content of two separate Divs.

I have a content page (<asp:content>) where I am using javascript and normally I am adding the attribut in the code-behind page. however I now need to add a javascript function that will cause when the body or panel loads. I have a test javascript function that simply shows an alert box but I cannot get it to display. Is there a special way to do this in a content page?

I am trying to call a Page Method using AJAX.
See the code
<asp:Button ID="btn_upload" runat="server" CssClass="btnEffects" Text="Upload"
onclick="btn_upload_Click" OnClientClick="return Validate();" />
Validate method is supposed to return true/false. The code for Validate method is
<script language="javascript">
function Validate()
{
var filename = $get('<%= txt_filename.ClientID %>').value;
PageMethods.IsValidFile(filename,OnSuccess, OnFailure);
// IsValidFile is a Page Method of bool return type
}
function OnSuccess(result)
{
if ( !result)
{
alert('File '+ $get('<%= txt_filename.ClientID %>').value + ' does not exist');
return false;
}
else
{
return true;
}
}
function OnFailure(error)
{
}
</script>
My problem is that even after showing the alert 'File somefilename does not exist'. The whole page refreshes (i.e, postback happens)
I want to call a validate function on asp:button click event and also want to do some server side work on this click like adding values to session variables and redirecting page to new one.
View 1 RepliesI 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);

I have overridden OnError method in the page:
public string script;
protected override void OnError(EventArgs e)
{
script = "alert('error');";
}
In the aspx, I have this:
<script type="text/javascript">
$(document).ready(function(){
<%=script %>;
});
</script>
I am simulating an error in Page_Load, but its not firing the alert. If I switch the code from OnError to OnLoad, it works great.
I am working with vs 2008 and C#. I am having a code behind function as follows(not complete)
protected void btnShowZone_Click(object sender, EventArgs e)
{
string setofalllatsandlongs = null;
foreach (string s in ar)
{
[Code].....
</div>In thIn the click event of the btnShowZone(in bold) i am calling the code behind method and from that i am trying to call the js function using the script manager class.
But the javascript method is not getting called.the control is not going to the js function.
I have a script manager and calendar extender on my aspx page. When I call a javascript function from my code behind page, the calendar extender doesn't work
ScriptManager.RegisterStartupScript(Page, this.GetType(), "javascriptfunction", "<script language=javascript>function();</script>", true);
OR
Page.ClientScript.RegisterStartupScript(this.GetType(), "javascriptfunction", "<script language=javascript>function();</script>", true);
i have used PageMethods to access the server side functions in javascript , but now my problem is that with pagemethods your controls will not go throught the full page lifecyle and these leads me to have "Object not set for an instance of an object" error. Now can someone come with a differnt approach without using pagemethods. What i want is to call a server side function , i dont want to pass any parameters to it

When I call test() from javascript i want it to return false but cant seem to geta value from test.
Let's say you have a Javascript function that calls a web service method. So that webservice completes and calls a callback function, which has the result.
How do I get that result back into the original function that called the web service method? Essentially, I'm trying to "synchronize" an asynchronous call.
Update:
This is what I'm trying to do. I'm validating based on the return value of a web service.

I am trying to call a JavaScript function from my ascx control code behind in the catch blockI have tried the below two ways but they don't seem to work.
Page.ClientScript.RegisterClientScriptBlock(typeof(string), "script", "test();", true);
ScriptManager.RegisterStartupScript(Page, GetType(), "err_msg", "alert('error');", true);
function DatalistFunction(argumentid) {
set_minimum_points_for_session = value;
SetSession(set_minimum_points_for_session);
Redeem(argumentid);
}
this is my code which i am calling on link button onclientclick event.
sometimes what happens is redeem function gets called first and then setsession function gets called. do i need to put some delay or something between the 2 functions, so that they run everytime in their own order
I have a web form in which I create many controls including a submit button dinamically.
I want to check a condition in the button's click event and if it comes true, call a javascript funtion to show an alert. but the problem is when I use :
Page.RegisterClientScriptBlock("ClientScript", script);
in the btn_Click event, it is not working. I guess the script should be registered at page_load.
