Passing Values From Client Side To Server Side Python Script
Jun 1, 2009
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.

I have a Hyperlink within a String like below:
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 am building a client-side and server-side solution and want to use JSON through Ajax in both directions. I have ASP or JavaScript server-side, though Microsoft's support of server side JavaScript seems nil, so I am reluctantly conceeding to use ASP. I'd appreciate suggestions on available solutions to encode/decode JSON on the server-side (ASP or JavaScript). I don't plan to load jQuery server-side so that rules out plug-ins. I'd also like to know what is the latest client-side encode/decode for JSON. Is it built in jQuery or a plug-in? In both server and client, decoding JSON securely is key, so using eval () to decode is out.

I have the following PHP code, which uses server-side validation, which works fine. It the user leaves the text field empty it stores an error in a session array which is outputted on the page where the $_GET['id'] variable came from. I also implemented a snippet of javascript code that just checks to see if the cell is empty and throws up alert box. The problem is that both the javascript code and php error validation are both running when I click submit. The PHP code should be a backup to the javascript code in case the user has javascript turned off. The client-side validation should be the default. Not sure if this change should be made in my PHP Code or Javascript Code.
PHP CODE:
session_start();
require_once("../Modules/Connection_Functions.php");[code].....

I have a web form that has a checkbox on it and a textbox associated
with it. I want the textbox to be displayed when the checkbox is checked
and I want this to happen on the client-side instead of posting back to
the server. The checkbox is a server control (asp:checkbox...). I can
write some codebehind that will display an alert message upon checking
the box that looks something like this...
Page_Load...
Dim s As String
Dim scriptString As New System.Text.StringBuilder
chkExpDate.Attributes.Add("onclick", "alertmsg()")
scriptString.Append("<script language=JavaScript> function alertmsg()
{")
scriptString.Append("alert('hi'); }<")
scriptstring.Append("/" + "script>"
s = scriptstring.ToString()
Page.RegisterStartupScript("startup", s)
End Sub
I used this as a test to make sure the server control was running the
script. But, when I change the script to assess the value of the server
control checkbox such as checked = true, I get errors and if I just try
to display the asp:textbox, it doesn't work either.

I have the following client-side Content Management System VBscript which works great, now I'm looking at getting it to work server side so that I can update using online login rather than offline and having to upload files. To be honest, I have no idea where to begin with this,
Here's the full VB script:

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.

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
to postback and call a server-side function when this happens? I am
aware of the browser's native "onunload" event, but am not certain that
what I'm looking for is actually possible.

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 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.

I have a TreeView populated from a SQL Server database (via an XML doc). The TreeView includes checkboxes on each branch and leaf. Each entry on the TreeView may or may not inherit access permission from its parent. That is, if you're granted access to branch "A", you automatically get permission to leaves "A1", "A2", and "A4", but not to "A3", as its inheritance flag is set to false.I have created an array of struct's on the server-side.
Struct format is:
public struct TreeInheritData
{
public Int32 namespaceID; // this identifies the node
[code]...
The array is populated with these structs.The TreeView I'm using (from Infragistics) has a client-side event when the CheckBox status changes.So, what I need help on is getting this array of structs from the server to the JavaScript, and then being able to access the structs so that I can determine whether to change the status of the child nodes' checkboxes.

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",

I'd been looking for some way to get server date/time without using any server side script (such as ASP, PHP, etc).
I found this and it worked just excellent for me! I just want to share it because it wasn't easy to find.
I created a js document with code:

Now, I can use this js within a html like this:

Provided an interface to a search engine in which the onchange event in
a select list element generates between 7 and 13 additional elements
depending on the option chosen.
Here's what the customer *now* wants to do:
Generate between 200 and 350 elements. Furthermore, the logic is going
to be more complex.
I would be happy to make that happen, however here's my concern: I'm
already doing this from the server side, using CGI. I wonder what is
going to happen when we put that degree of "work" on the client browser.
I would welcome comments, caveats, or pointers to documentation and
discussions on this subject.

I have a table that changes its cell (input text) colors when their contents
have changed (actually on keypress) and shows a couple of buttons
automatically, UDPATE and CANCEL. This works partially, though detecting
enter and escape doesn't seem to work, or parhaps calling the button click
events directly doesn't (see below).
In addition to getting the ENTER and ESC keypresses to fire their
appropriate button clicks, I need to be able to collect information on which
cells have changed, so on the page loading again I can read this
information, perhaps from a hidden field, to use to update a database
server-side.
<script language=javascript>
function GirdTextKeyPress(txtID, btnsContainerlID, btnUpdateID, btnCancelID)
{
var txt = document.getElementById(txtID);
txt.className = 'GridChanged'
var bc = document.getElementById(btnsContainerlID);
bc.style.display = 'inline'
var btnUpdate = document.getElementById(btnsContainerlID);
if (event.keyCode == 13)
{
event.returnValue=false;
event.cancelBubble = true;
btnUpdate.click();
}
var btnCancel = document.getElementById(btnCancelID)
if (event.keyCode == 61)
{
event.returnValue=false;
event.cancelBubble = true;
btnCancel.click();
}
}
</script>
<style>
Input.Grid
{
border-style:none;
}
Input.GridChanged
{
background-Color:Yellow
}
</style>

I have several xml files and a common stylesheet on the server. In my
html I have a sidebar of links. For each link I fire an onClick event
that triggers an xml load and transform with the output displayed in a
small popup. Everything works great for one click. My issue is that in
Firefox, each subsequent click concatenates the results to the previous
tranformed results. How can i start fresh each time. I've tried
resetting all variables involved but the problem won't go away. This
works fine in IE by the way. Does anyone have an idea on what the issue
could be?
