Hi all,

I have a form with 3 submit buttons, i want to use javascript to detect which button was clicked and based on that i'll do something else. Can some one please tell me how to do it?

instead of using subimt buttons, just use buttons:

<input type=button name=firstButton onclick=&quot;someJavascriptFunctionName()&quot;>
<input type=button name=firstButton onclick=&quot;someOtherJavascriptFunctionName()&quot;>
<input type=button name=firstButton onclick=&quot;yetAnotherJavascriptFunctionName()&quot;> theEclipse

TransTech,

Eclipse is right, change your submit buttons to standard buttons and just issue the document.formname.submit() method in your function if and when you want to submit the form. More specifically on how to determine which button was clicked.

<input type=&quot;button&quot; name=&quot;b1&quot; value=&quot;Button 1&quot; onClick=&quot;yourFunction(1);&quot;>
<input type=&quot;button&quot; name=&quot;b2&quot; value=&quot;Button 2&quot; onClick=&quot;yourFunction(2);&quot;>
<input type=&quot;button&quot; name=&quot;b3&quot; value=&quot;Button 3&quot; onClick=&quot;yourFunction(3);&quot;>

At this point, it's irrelavant what you name the buttons or supply as the value or button text. Assuming all three buttons are calling the same function, your function still won't know which one was clicked unless you pass a parameter to the function.

See where we pass a parameter to the function with a number myFunction(buttonnumber). Then your function could look like this.

function myFunction(bn) {
  if (bn == 1) {
    // DO SOMETHING FOR BUTTON 1
  } 
  if (bn == 2) {
    // DO SOMETHING FOR BUTTON 2
  } 
  if (bn == 3) {
    // DO SOMETHING FOR BUTTON 3
  } 
}

Hope that provides some further help.

if you are going to have one function to parse for the numbers, a switch is usually cleaner:

function myFunction(bn){
switch(bn){
case 1:
//do something for button 1
break;
case 2:
//do something for button 2
break;
case 3:
//do something for button 3
break;}
