I have a web form that has a button. The click event of the button submits the form for processing on the server. On the server, after the processing is complete, I want to call a JavaScript function. I don't want to attach it to a control. Just call it.

View 1 RepliesHow to call JavaScript function from server side
View 2 RepliesI have a project that uses PageMethods to call functions on the server. The server functions (written in C#) return the values as array of strings, without doing any kind of serialization and in the client side (from Js) the accessing of the return values is by using static variable called arguments. I found that sometimes for some users (cases are not repro) sometimes an exception occured
"WebServiceFailedException the server method 'Foo' returned invalid data. the 'd' property is missing from JSON."
Some searching on google I found that people are serializing the return values using DataContractJsonSerializer class and in js accessing the return value using one of the callback function Example:
function OnRequestComplete(result,
userContext, methodName) {
var Person = eval('(' + result + ')');
alert(Person.Forename);
alert(Person.Surname); }
So is the first technique is correct? or what?
P.S:
the function on the server is defined on the default.aspx.cs file as follows:
[System.Web.Services.WebMethodAttribute(), System.Web.Script.Services.ScriptMethodAttribute()]
public static string[] Foo(string s);
from the client side the calling is as follows
PageMethods.Foo("value",OnSuccess);
Also all the users have the same browser version (IE8)
What I want to do: dispose of a session upon detecting an "OnBeforeUnload" event in the client. I know it doesn't fire 100% of times (90% accuracy works fine for me)
Here I saw how to do it with ajax, this system, however, breaks down with ajax: I can't use it at all.

View 1 RepliesI have multiple HyperLink controls and I want to enable or disable different panels base on which HyperLink I clicked on. This should be done using javascript. The question is: Is that possible to even use javascript for this? I know other button controls, there is onClick property but not in Hyperlink.
View 5 RepliesI don't need to run the function every time the page loads!!
But, I would like to have the control when the function is to be called.
The only way I thought of is calling my function with OnLoad in the body tag and having a hidden field to be checked and then run the script accordingly.
e.g:
<body onload="ScrollToView();">
Is there a better way? For example, running the function from Page_InitComplete handler?
in aspx:
function checkFunction(no,name){
}
in cs:
string test_name ="hello";
StringBuilder Strname=new StringBuilder();
Strname.AppendLine("<td ><input type=checkbox onclick='checkFunction("+no+","+test_name+");' runat='server' name='checkbox_name' value='XX'</td>");
when i call the checkFunction(), i can't pass the 2 argument as there is error.
