2 Submit Buttons, How To Check Which One Client Side
Sep 1, 2004
I have a form with 2 submit buttons, each with a different value attribute. I can tell which one was clicked after the form has been submitted but I need to check it client side. Here's why: I am doing form validation using the onSubmit event, but I only want to validate if one of the buttons was clicked and not the other.
What's the best way to do this? I thought about having a hidden form field that I set with the onClick of the button I don't want to validate. Is this the best way?
Here are my 2 input tags:
<input type="submit" name="Submit" value="Add reply">
<input type="submit" name="Submit" value="Close">
I tried checking myform.Submit.value in my form validation but it comes up "undefined". I guess it isn't defined until the values are actually posted to the server. Or am I missing something here?

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� 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.� 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:

I've literally tried everything. Read 26 tutorials, interchanged code, etc. My validation functions all work. My AJAX functions work (tested manually using servlet URL's). The second servlet validates the reCaptcha form that's generated on my webpage. After the form is validated, even if everything's correct, nothing happens upon clicking submit. I even have an alert pop up if with the captcha result, just for middle-layer debugging purposes.
I want to do all of my validation clientside; none serverside. However, going to be tough if I can't get my god damn form to submit. I've been puzzled by this for close to 36 hours straight. I can't see, and I'm going to get some rest and hope that there is some useful insight on my problem when I return.

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 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 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.

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?

I am developing a mobile app. I have a script that will read the contents of a csv into an array. It works great, however I am not sure how to take that array and insert it into a db. The following is the script that reads the csv --

var X = !window.XMLHttpRequest ? new
ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest;
X.open(V ? "PUT" : "GET", U, false);

what I'm trying to do is get the browser to display a warning if the file the user inputs is one of an array of allowed files (which is thoroughly checked server-side), but are wasteful in size (like .bmp .tif .avi .wav). I want them to be able to upload it if they want, but just to notify them they could save space by converting to a smaller format (as they pay per megabyte). So on submit I need to get the file input value, check the extension, and if its allowed but wasteful to display a message with a yes and no button, which would submit if they press yes and not if they press no.
I'm not very experience with javascript but I know a lot about php, but I don't really know what the equivalent functions are.

Is there any way to do this? For example, with some kind of try/catch block?

I have to sort a table where few columns are dynamically generated .I searched the net and came out with sorttable.js included in my jsp file . then called this function in <body>onload event as initTables('id_of the table"); It was working out for me..I have some columns which introduce the concept of hidden columns so when I try to hide it instead of hiding it just sorts..Is there a way to not to sort the first row alone becoz my first row is the total amount. I do have expand and collapse columns in my table I am not able to sort the parent row get sorted along with the child rows. I want the parent row to be static and only the child rows getting sorted ..
