how to pass javascript variable values to server side code i used a hidden field and passed he value in it . i do get the value in hidden field but on using request("hdfield") its blank how do i get the value frm javascript
View 1 RepliesOn the server side I have a php generated session parameter.
I need to pass it to javascript on the client side page.
I saw on the web the following solution code...
I tried it but it did not work.
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 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 know at this point is that these is a difference in the array formatting between PHP and JS. The magic bullet is supposed to be json. However, this code does not work as advertised.

The variable $prt is list of associative arrays, so to get a value in a particular row manually , $prt[0]['location'] should give me the value for location in the first row of output. All of this works just fine if i hard code this in html and php. However, I want to dynamically produce the rows as needed which requires that a loop employed. The application also requires that the user may add a row which also need to be accounted for when posting.
I think the best solution is to make this a totally javascript entity. All I need to do is to be able to pass in the server side data. Calling JS from PHP does not work, although i have found many places where they show basically the same code , claiming that it works. think json needs a bit of tweaking to make this happen, but i'm not sure how to proceed.
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 am new to jQuery, and learning more about Js by doing. I can hand-code HTML and CSS very well and understand OOP effectively. However, troubleshooting complex Javascript code combined with jQuery is a challenge to me, but I really want to learn. I am using Windows XP Professional and IE 8, FF 3.6.

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 2 Replies View RelatedI 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.
View 1 Replies View RelatedI 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 had a import function which allow for user import data from excel file. The number of row was dynamic, mean that user may import hundred or data or may thousand of line.
should i perform client side or server side validate?
the problem i faced was if the import thousand of line, i need display out thousand of text (multiple by 6, cause 1 got 6 fields)
the take a lot of time to loading and cause browser "hang" (response slow)
any solution for me?

Within an aspx page, I have a form with asp controls (text boxes) that I'm loading within a jQuery modal popup dialog. Once the user fills out the form and the register button is clicked in the modal form, it invokes a code-behind function, which seems to be working fine. However, the problem I'm facing is in the code-behind function; none of the field values in the modal popup form are being passed to the code-behind function.I was unable to attach some snapshots directly to the post, so I uploaded it at the following urls:

How can I make the button call the click event so that the server side method btnExecute_Click() can be called? Also, this button calls a javascript function before server side even.
I am writing a Javascript to sort and write out some stuff. PHP is not an option so I need to get this script working.
The problem arises when I want to make a link to the next page. (i.e. Like the link in google for the next 10 results)
I have <a href=# onclick=FUNCTION(VALUES)> written dynamically by the script.
It is written onto the document correctly, but the problem is, when the link is clicked, some seemingly random values are passed to the function.
I also have an invalid character error that arises when I pass the "whereVARquoted" variable into my function (code 2) which disappears when the variable is removed (code 1).
My code is below:
Code 1:
<script>
Code 2:
<script>
However, this piece of Javascript uses some other script which is large.
<script src = "./js/tmp.js".....>
This will work if the file "tmp.js" is local. However this reduces the
portability of my *utility* Javascript
as users have to have that "tmp.js" for every webpage they have (if they
want to use it :D)
I thought of uploading "tmp.js" it to somewhere and change my code to
<script src = http://www.somewhere.com/js/tmp.js ....>
The all the users have to do is copy the piece of code that I wrote
BUT THIS DOES NOT WORK. I TRIED IT.
My questions are:
1. Is there something wrong with server-side Javascript? Or am I missing
something?
2. Is there another way to make my code portable?
I might be turning a corner today and seeing the light. I might still
be confused :)
If JavaScript is the language for the browser then why do servers use
Ruby/Rails, Perl/Catalyst, Python/Turbogears or PHP/Cake? Is it because
the prototype-based language is too different to be chosen except when
necessary. Is it because browser bugs make people think JavaScript is
bad? Is JavaScript not suitable for the server-side for any reason?
I imagine that if server-side programmers started to learn JavaScript
then the client-side code in the world might start to improve.
Translation layer libraries like Prototype.js or Mochikit wouldn't need
to exist. The more I learn about JavaScript the more I like it. It is
difficult to learn however for multiple reasons.
Does Javascript work "out of the box with IIS" as an
Active server page? ie. does it have the ability to open files
ect.?
I tried this command and it does not seem to work.
var fileSys;
var txtFile;
fileSys = new ActiveXObject("Scripting.FileSystemObject");
txtFile = fileSys.OpenTextFile("./junk.txt",1,false);
I can't find examples on the web. What would I search for to find out
about objects the Scripting.FileSystemObject?
Background:
I work at a large company with a corperate IT group.
I need to write some server side scripts. The servers they
have are Windows 2000 with IIS installed. If additional
software needs to be installed I will be forced to use VBscript.
I have a number of server-side Javascript applications running on an
old Netscape Enterprise server. I want to move them to Apache. Is
there a way to do this without extensive recoding ? My code contains
a lot of Oracle and SQL Server database interaction.
I'd like to adapt some Greasemonkey scripts that I've written and have
them applied to html files on the server side before the files are sent
to users. I'm only looking at adapting scripts that make static
changes to pages. For instance, consider a script that removes from
the DOM any img that has "ad" in its src.
I'm sure there are better ways to do this and I'm not even necessarily
looking for an extremely efficient solution. Mostly, I just want to
know if there's an existing product that could do this or with
reasonable effort could be made to do this.
