I would like to know what are the best practices in using Javascript in ASP.NET in a pre-AJAX and pre-jQuery era. What I meant by pre-era is not the time before AJAX/jQuery was created, but rather the time before it is popularized and widely adopted (by a significantly large number of programmers).i.e. Is it good thing to store the script in a string variable and register it on demand (RegisterClientScriptBlock) or on startup (RegisterStartUpScript)?Although in using Javascript in ASP.NET, its usage in PHP and JSP are also welcome.
View 1 RepliesI am looking for a way of graphically showing a countdown. I am working for a large Hospital and have written an Ambulance page that shows ambulance arriving in a datagrid with the time of arriving at the hospital in minutes and seconds (plus other info).They have asked me for somehow visually representing the information, so it fits with there other visually appealing Emergency Department web application (e.g. progress bar or something better):1) Can somebody show me (visually appealing) design examples on how this could be done2) Are there solutions in .Net (ASP.net or JQuery or Javascript) since this is our preferred technology

I have a keyboard-controlled menu which I did with jquery (When I press down, it marks second option and so on...)
But after I select the option I need, I want to click enter to call the button's OnClick method as if the user really clicked it. Which means I have to do a postback.
how do I do that?
I have some code like below in an aspx page:
[code]....
I had thought that returning false would keep my asp.net OnClick even from firing, but it still does. I've confirmed that it is getting to the return false section of code using alerts. Is there anything I can do to stop it from firing using jQuery/javascript?
I using jQuery-UI sortable which works fine. The problem that I am having is that the message "New order saved!" or "Save failed" is not displaying in the < p > area. The function is either not executing or something.

I want to prompt the user before allowing them to save a record. So let's assume I have the following button defined in the markup:
<asp:Button ID="btnSave" runat="server" OnClick="btnSave_Click"></asp:Button>
To force a prompt with normal javascript, I could wire the OnClick event for my save button to be something like this (I could do this in Page_Load):
btnSave.Attributes.Add("onclick",
"return confirm('are you sure you want to save?');");
The confirm call will block until the user actually presses on of the Yes/No buttons, which is the behavior I want. If the user presses 'Yes', then my btnSave_OnClick method would be called.
For the jquery dialog that is the equivalent, I tried something like this (see below). But the problem is that unlike javascript confirm(), it's going to get all the way through this function (displayYesNoAlert) and then proceed into my btnSave_OnClick method on the C# side. I need a way to make it "block", until the user presses the Yes or No button, and then return true or false so the btnSave_OnClick will be called or not called depending on the user's answer.
Currently, I just gave up and went with javascript's confirm, I just wondered if there was a way to do it.

I want a similar behavior of "confirm delete" option in ASP.Net Gridview, as this questions shows How to add a "confirm delete" option in ASP.Net Gridview ? but using Jquery Confirm Box.
I'm having a lot of problem with postback behavior and asp.net page flow.
I want domething simple as:
<asp:Button ID="ButtonRemove" runat="server" Text="<%$ Resources:Localizacao, BUTTON_REMOVE %>" OnClick="ButtonRemove_Click" OnClientClick="displayConfirmDialog();/>
how I can fire the OnClick event in javascript, or how a can put a Panel as confirm dialog?

I'm beginner in JQuery, how could I select an object using JQuery ?
This is the code:

$("#" + senderID).hide(200);
// this exception is thrown // Microsoft JScript runtime error: Object expected
}
</script>
<div id="div1" onclick="javascript:Hide(this.id)"
Suppose I have an url like [URL} I can retrieve the 'form' value in code behind like Request["from"].How can I do the same using Javascript?Can I do this using Jquery also?If yes how can I do this?
