If a value is stored in a session object. How do I retrieve the session value in a function in javascript. I tried
var background1 = '<%=Session["test"]%>'
But I get blank
I'm trying to create a JSON object on client-side and pass to a server-side function. Then instantiate it on server-side using JSON string representation.
So I create jSON object on client-side
var myJsonObject = {
"arg1": var1,
"arg2": var2
}
and pass it in to
WebForm_DoCallback(controlID, myJsonObject , null, null, null, true);
When I try to retrieve this JSON object on server-size I get as a string representation of JSON [object Object]
So in following server-side function, the argument value is [object Object]
public void RaiseCallbackEvent(string jsonObj)
I was expecting a string representation of JSON object. How do I pass in a string representation?
I want to pass to an array of controls' IDs to a javascript script function so it will switch control's enable state.
For example, in C# it would be like this:
func(false, new[] { "Control1", "Control2", "Control3" });
In that function I want to find corresponding controls and disable/enable them. For one control I do this next way:
<script type="text/javascript" language="javascript">
function switchControls(value, arr) {
for (var n = 0; n < array.length; n++)
document.getElementById([n]).disabled = value;
}
</script>
<asp:CheckBox runat="server"
onclick="switchControls(this.checked,
[
'<%= Control1.ClientID %>',
'<%= Control2.ClientID %>'
])"
Text="Take?" />
How to implement this properly? Have I to use jQuery?
I am calling a WebMethod from this code:
if($(this).attr("checked")) {
..
MyWebMethod(variable1, variable2, onSuccessFunction);
}
The MyWebMethod returns an integer, and I want to set $(this).attr("id") of the jQuery object above to the returned integer. Basically, I'm trying to do the equivalent of an MVC Ajax.ActionLink...AjaxOptions {UpdateTargetID =...} However, I can't figure out how to get both a reference to $(this) as well as the returned value. For example, if I do:
MyWebMethod(variable1, variable2, onSuccessFunction($(this)));
I can succesfully manipulate the jQuery object, but obviously it doesn't have the return value from the MyWebMethod. Alternatively, the first code block with a method signature of onSuccessFunction(returnValue) has the correct return value from MyWebMethod, but no concept of the jQuery object I'm looking for. Am I going about this all wrong?
I am collecting user roles into a single dimension string array.
I have a repeater that its source set to that array. The repeater template includes list of checkboxes for the values in the array.The checkbox text is set to: Text='<%# Container.DataItem %>'
All is good till this point.
But I am trying to call a javascript function triggered by clickign a checkbox and pass it the container.dataitem, but the javascript doesn't seem to be reading the value and either complain about string not being in correct format or that treats the container.dataitem as a liter. This is the trial that didn't work (I tried many different things too):
DetermineVal(<%# DataBinder.Eval(Container.DataItem) %>);
determineval is my javascript function
Can I do that with a single dimension array?
in aspx page
<cmp:MenuItemInfo Text="Delete" onclick="javascript:deleteRow('## DataItem.ClientId ##')" />
In Javascript
function deleteRow(rowId)
{
Projectgrid.deleteItem(Projectgrid.getItemFromClientId(rowId));
}
but the arument is coming as a string '## DataItem.ClientId ##' instead of correct clientID.
I have a GridView with an image button in a TemplateField in the last column.
I would like to pass the GridView row values (Bound Field Values - a record) to a JavaScript function to create another html table of selected records in ClientSide (like jCart-A shopping cart).
I would like to know how to pass all GridView column values to the javascript when the image at the end of the respective row is clicked.

I tried to pass a string value into a JavaScript function like below: <%= "'" + prop.property_description + "'") %>) But it does not seems to be the best option, is there a better way to do the above without concatenate the string values with "'"?

I have the following Silverlight control defined:
[Code]....
I have exposed the following method in my Silverlight control (Page.xaml.cs) to be accessible to Javascript:
[ScriptableMember]
public bool HasPendingUpdates()
{
return btnSave.IsEnabled;
}
I then have a Javascript test function in my aspx page that is trying to do something with it:
var imageViewer = $("#objImageViewer")[0];
if (imageViewer.Content.Page.HasPendingUpdates())
{
alert("Pending Changes Exist!");
}
else
{
alert("NO Pending Changes Exist!");
}
Problem is that it fails after the Content object. I have tested the following:
var imageViewer = $("#objImageViewer")[0];
imageViewer // Valid
imageViewer.Content // Valid
imageViewer.Content.Page // Invalid
imageViewer.Content.HasPendingUpdates() // Invalid
So I am not sure what I am doing wrong. How do I get to the function within Content?
I am using IE8, Silverlight 3, ASP.NET. The silverlight control is created with the object tag as I don't think the control is an option in Silverlight 3+.

I am working on ASP.NET 3.5, c#, visual studio 2010. I have made a master file and a default page that uses this master file. I have placed a couple asp:contentplaceholders in the master and corresponding code in the page that uses this master. I have also inserted JavaScript like this in the content page (and not the master):
<asp:Content ID="Content6" ContentPlaceHolderID="Mainpage" Runat="Server">
<script src="path1" type="text/javascript"></script>
<script src="path2" type="text/javascript"></script>
<script type="text/javascript">
$(document).ready(function () {
var options = {
//some java code
};
$(".mycssclass").effect(options);
});
</script>
</asp:Content>
On running the website I get the following runtime error in visual studio: Microsoft JScript runtime error: 'this.node' is null or not an object and it point to some function inside the JavaScript like this.node.onload=function(){..............//I am not a java guy so do not know much about this Where am I going wrong? Why does the site compile correctly but throw this runtime error? I also tried inserting this java code inside the master file in the <head>, but same error.
