Retriving Data From Some Asp.net Object To Client Side Javascript

Mar 9, 2007

How can I, for example, retrive data from Profile object (or what so
ever) to some variable declared in javascript tag on client side?

For example, let's say I have this code in Some_Page.aspx:
....
Profile.Name = "Some Name";
....

And I have some variable in java script tag:

var someVariable;

How can I get this "Some Name" from Profile.Name to someVariable?

Post Data To Server From Javascript On Client Side

Jul 23, 2005

I have a few values and variables that I want to post to a server
(without using a SUBMIT button). Is there a way to post data from
within javascript - do sockets or connections have to be open for this
to work?

Sending Values From Server Side To Client Side Javascript

Jul 20, 2005

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>

Accumulating Data Client Side On Form

Nov 4, 2005

I want to create a purely client side piece of dynamic html where if someone enters data on a form, the data is held on the form and the form can be saved off as an html file. Yet I find that with the code below, if one enters data in the text box and hits the enter key, the data vanishes. How can I retain the data on the form? Can I use some form of event handling to ensure the data is stored in the form fields?

<BODY>
<form name="myform">
Input1:<input type="text" name="box1"><br>
<input type="button" name="add1" value="Add1" >
</form>

Scale With Client-side Javascript

Jul 23, 2005

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.

HTML Forms And Client-side Validation W/ Server Data?

Oct 28, 2010

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.

Calling Server-side Function From Client Javascript

Nov 29, 2005

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.

navigator.preferences() that contain the info, but I have found none
that can *always* be expected to exist.

JQuery :: Encode/decode Of JSON - Server-side And Client-side?

May 26, 2009

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.

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.

How To Check The Input File Object File Size On Client Side?

Dec 20, 2004

I have a form with three Input File form objects in which the user can add image files. But I am worried about the problems these controls can lead, because to check the file size the server needs to receive the entire file, so serious problems may happen, for example:

1. Malicious user trying to collapse the website sending big files.

2. Users that have not seen the warning “Maximum size: 100 KB&#65533; for each image, and try to send three image files consisting in 1,5 MB each one. These users will have a bad experience waiting one hour or more to upload the images, and after that receive an alert saying “Oooops! Your image files are too big.&#65533; And also, web server will waste an important amount of resources. The same case with 100 users at the same time can be a nightmare!


I have been searching a way to check the file size on client side without having to force user to install anything, but I think that there isn’ t nothing to do with javascript. But I found an interesting PHP article that explains a way to do it with this server side language. The technique consists in:

“A hidden field (measured in bytes) that precede the file input field, and its value is the maximum filesize accepted. This is an advisory to the browser, PHP also checks it. This form element should always be used as it saves users the trouble of waiting for a big file being transferred only to find that it was too big and the transfer failed. Code:

Adjusting Code To Use Either Server-side Or Client-side Validation--NOT BOTH?

Sep 11, 2009

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].....

Client Side Script With Server Side Controls

Jul 20, 2005

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.

Problem With 'undefined' Object In Server Side JavaScript

Jul 23, 2005

I'm displaying a loggin page.

If the user entered an invalid UserName/Password I display the page again.
When this happens I want to give the user a different message then the one displayed when the page was initially displayed.

I use the Response.Redirect method from the page checking the submition.
When I do that I call the page with a parameter like this Response.Redirect("Page.asp?FROM=1").

When I get the parameter in the page I know I need to show a different message.

The problem is that if the page is called without the parameter, I
cannot determine that the parameter is missing.

The codse is very simple:

from_flag = Request.QueryString("FROM")

Now is the problem -

if I use if(from_flag == 'undefined') - this condition return
false.
but if I display from_flag using Response.Write(from_flag) I get "undefined"

if I use if(typeof from_flag == "undefined") - this does not work since the typeof return "object" in both cases when I call the page with the parameter or without the parameter.

also I tried to comnpare with null does not work.

By the way if I use VBScript as the script lang - it works fine I just need to compare the from_flag with vbNullString and all is well....
