@felgallFeb 01.2008 — If each button has the same name and a different value then test which value is assigned eg.

<input type="button" name="mybutton" value="button1">

<input type="button" name="mybutton" value="button2">

then the value in mybutton.value will be the value of the button that was clicked.

@rejoy_studauthorFeb 01.2008 — nope its got 2 different names as well.

but how can we know which one is clicked

document.frmMain.btnSave.value will always give the value 'Save' right

@fpmarinFeb 06.2008 — Example:

<!--xhtml code-->

<form id="f">

<input type="button" />

<input type="button" />

<input type="button" />

</form>

// javascript code

function buttonIndex()

{

var i=0;

while ( i<B.length ) {

if ( this===B[i] ) break; // Note the "three = symbol": ===. Very important

++i;

}



if ( i==0 ) /* do something with the first button */;
else if ( i==1 ) /* ... second button */;

else /* ... third button */;

}

window.onload
=


function()

{

B=document.getElementById("f");

B=B.getElementsByTagName("input");

var i=0;

while ( i<B.length ) B[i++].onclick=buttonIndex;

}

Success!
