hi friends,
i have 3 buttons ‘add’,’update,’delete’ in my jsp what i want is depending on the button name i am trying to do the actoin.

Below i have given my function —–> field i will get my “Button Name”…

My question is how can i send a button name just like a parameter to servlet?
like for ex:
“../Customer?field.name” <——— is this possible i am getting error is any other ways?

[Code]
function CustAction(field){
var name=field.name;
var FieldName = document.forms[0].PassportNo.value;
document.forms[0].method=”Post”;
document.forms[0].action=”../Customer”;
document.forms[0].submit();
}
[/code]

@gpm1982Nov 20.2007 — The correct URL with parameters is:
../Customer?field=value

you can even include this parameter into the function as follows:
function CustAction(field){
var name=field.name;
var FieldName = document.forms[0].PassportNo.value;
document.forms[0].method="Post";
document.forms[0].action="../Customer?field=value";
document.forms[0].submit();
}

document.forms[0].action="../Customer?field=value";

is it field.value of field=value... because there is no "value" defined...

@gpm1982Nov 20.2007 — oops sorry, my bad. for that, you need to edit the function code:
function CustAction(field){
var name=field.name;
var FieldName = document.forms[0].PassportNo.value;
document.forms[0].method="Post";
document.forms[0].action="../Customer?"+field.name; // edit this line
document.forms[0].submit();
}

I'm not sure if it's field.name or field.text

Test both and see which one works ?

[code=html]<form method="post" action="Customer">
Username: <input type="text" name="txtUsername" />
<input type="submit" value="Submit" />
</form>[/code]

and on the server side (for this example, I use PHP):
[code=php]<?php
if( isset($_POST['txtUsername']) ){
// commands
}
else{
echo "No params found...";
}
?>[/code]

Success!
