Question

I am trying to call two javascript functions on single events. Here is my function calling code.

<input type="text" name="cbh" id="c8"  value="0"  onkeypress="return isNumberKey(event);calculate();" />

First function to allow numbers only and it have following work flow.

    function isNumberKey(evt)
{
    var charCode = (evt.which) ? evt.which : event.keyCode
    if (charCode > 31 && (charCode < 48 || charCode > 57))
    return false;



    return true;
}

For debugging purpose, sencond function has just one line.

function calculate()
{
    alert("ok");

}

Now, first function is being called 100% ok. But second function does not seem being called. Any suggestions?

Edit: I want to call second function after execution of first function.

Answer 1

Because you are returning after the first call.

If you want to skip the second if the first returns false:

onkeypress="if (isNumberKey(event)) { calculate(); return true; } else { return false; }"

If both are to return status, and the second should only run if the first returns true:

onkeypress="return isNumberKey(event) && calculate();"
