    </div> 
    <input type="submit" value="Calculate" />   
</form>

I want to validate the 2 input fields so I used the livevalidation found here http://livevalidation.com/ to get rid of those ugly "alerts".

My problem now is that I want to do some calculations in testfunction() and I don't want the form to be submitted. I could have used a type="button" instead of "submit" but that way the livevalidation won't work.

So when I type something like:

function testfunction (myform) {

var odds = myform.odds.value;
var handicap = myform.handicap.options[myform.handicap.selectedIndex].value;
    //much more code here
    return false; }

It ignores the return false and the form is submitted. If I don't have anything that gets the input from the form it works fine. So how can I get the input on submit and return false so the form wont be submitted?

Answer 1

The thing you can do is

  <input type="submit" value="Calculate" onclick="return (testfunction ('yourform'));" />

it will return the return ( false ) of the function while calling it.
