I'm doing some jquery and ajax work with C# asp.net MVC on the server.
I have this JS function:
function DeleteListing(receiptItemId){
$.ajax({
url: "DeleteListing",
type: "POST",
[Code].....
What I'm wondering is there ways to return values from DeleteListing on the server to the success function?
My login to the site is being processed using ajax, which does a redirect to the members page upon succesfull loggin in.The login feature however can in fact take a while because we need to initialise quite some data when a user logs in (his details, but also his privileges are loaded, his personal menu based on these privileges are being loaded, we are loading shopping cart info, we are initialising personalisation settings, and a whole lot more.It sounds like a big thing, but it isn't, and once logged in, the application is going great. the only thing is that the login proceure can take 3 - 4 seconds, and I would like to be able to show the client the progress of the serverside script:
"Searching your account..."
"Validating your privileges"
"Initialising your personal menu"
blablabla...
To do this, I might just call an ajax call that starts the login procedure, and then issue another ajax call every 1 second or so to update the status based on some session variables I set in the login procedure and that I can serve to the client when th next ajax calls come in, but I would love for this to work a little nicer as in just needing to initialise ONE ajax call which can send back statusupdates from the server...
I am developing a web form using python cgi which has two list boxes. On selecting a value from the listbox1, the list box 2 should get auto populated with appropriate values (which are taken from the DB). I have written a javascript function to get the selected value from the list box1. But I am struck with passing the values from the javascript to the python function written in server side in which I have written the DB related stuffs.

sSql = "SELECT DISTINCT " + "'Action' = '<center><a
href='+char(34)+'ChangeRequest.aspx?ID='+cast(Chan geRequest.ChangeRequest_ID
as nvarchar) +CHAR(34)+'>Open</a></center>',"
I want to invoke a Client side javascript function and pass the value
of the ID. How can I accomplish this such when a user clicks "Open" he
goes to a new window with the same ID.
I tried this but it does not work:
On Server side:
sSql = "SELECT DISTINCT " + "'Action' = '<center><a href= 'javascript:
NewWindow('+cast(ChangeRequest.ChangeRequest_ID as nvarchar)+
CHAR(34)+)'>Open</a></center>',"
On Client side:
function NewWindow(myID)
{
window.open("ChangeRequest.aspx?ID="+myID,"WindowName","width=500,height=600");
}
</script>
I want to send three text box values to server using jquery ajax. problem is that, i dont know the exact syntax to send three data. When i try sending one data(also change no.of parameters to one at server side method), its going good but when i try to send three text box values, its giving jquery error:"Internal server error". I think I am not sending data in correct way. Example below contains only two sending data, because i was trying to send 2 data first.
Below is the code:
function testCAll() {
$.ajax({
type: "POST",
url: "dbTest1.aspx/SendMessage",
[Code]....
how do i pass values back to javascript from the server via ajax? I don't want to pass entire html. Is there any way to simply pass a JavaScript object or an array without stuff like xml and json? I could probably do an eval() on the result to convert it to a javascript understandable array, but maybe there's a more clever way to do that?

View 3 Replies View RelatedI'm trying to implement a simple chatting website. For now what the code does is checking every 10 seconds if there are new posts stored in the database (newer than the last check, 10 seconds ago). Is there a more efficient way than doing this with a timer??? for example, is there some kind of event listener attached to the server that would notify the client whenever the db is updated?

View 4 Replies View RelatedWhat is the best way to get the client time to the server? Would I user http headers? (I dont know how to do that) or is ajax the best method? I could use ajax to send the unix timestamp to the server everytime a page loads and save the difference between it and the server timestamp as a session variable. sounds sensible?
I dont want to work with timezones but I do want to get the actual time set on the client's computer.
I understand that JavaScript resides on a server and is served to the client via the web server & the web browser.Is it possible to run JavaScript programs locally without the web server piece?
View 3 Replies View RelatedI posted the same post in PHP section but thought might be related to Javascript too. So here goes:
I want to create a decent log at clients side to show alerts from server.
So, server should be able to see a list of connected clients (registered user) on the website, and select a few of them, type something in textbox, clicks send to all of selected clients, and the message is shown in the log at client's website. Also plays a simple sound file when clients receive new message in the log.
The only way i can think of doing such a thing is having an active
server page that returns an image, that is generated on the fly. As
long as there is no caching on the client this in theory will allow
the client to perform an action on the server and display an image
generated on the fly as a result of this action without actually
reloading the page, simply by requesting an image.
id like to know how can i create a cookie on the client side as well as to script my server side coding to retrieve the cookie value.

I am developing an ASP.NET (C#) application and need some help. I wish
to call a server-side function (in the code-behind "file.aspx.cs") upon
a user clicking on the "X" to close the browser window. Is there a way

aware of the browser's native "onunload" event, but am not certain that
what I'm looking for is actually possible.
I'm new to JavaScript. I have relatively large amounts of text (~200 kB) that I need to transfer to my web application every now and then. Using RAR, I get a 5:1 compression ratio on these files, for example one of 180 kB is compressed to 34kB.
Is there some standard way to decompress files in JavaScript?
Is it somehow possible to setup a backend server to send a message to a client? Or it is a client always have to establish a connection? What I'm trying to code is a simple chat script that sends a message to the client once a member of the chatroom has logged out. The only way that I can make this work is if the client either sends a message (which is a POST call) or when a time delay occurs (I've set a timer to run every 30s after the last GET or POST call). But both of these are basically CLIENT -> SERVER calls. I don't assume that the other way (SERVER -> CLIENT) is possible? no?

This script is trying to talk (ajax) to the server that it comes from but I'm getting "Access Denied" errors. I'm well aware that cross-domain calls are not allowed for security reasons so my question is how does Google Analytics work because essentially thats what I'm trying to accomplish.

View 4 Replies View RelatedI know that Javascript is client side, but I'd like to know the best way to populate HTML drop downs in real time based on information typed in the other HTML form fields with information found on the server as opposed to the client.For instance if a user wants to select certain files located in a directory on the server, as they type in the pathname supposedly containing the files the drop downs continually refresh themselves with the server files listed in that directory (if it exists, and apache has permissions to see what's inside) as if it was showing client files instead.
What would be nice is if my browser could continually query the server for some of its private information and not have to refresh itself to obtain it, whether that means the server-side would have to continually refresh itself makes no difference to me as long as the client-side doesn't have to. But I guess this is not possible because no matter what you would have to at least refresh the client-side page once?Submitting the form to a CGI or PHP script would not work because I need this functionality to help populate the form BEFORE I send it.I would like to not have to press a button to update the form every time I change the pathname and need to update the drop downs since this would be annoying.
