one event two functions 1

[ttuser4]

hi, i need to call two functions for a textbox on onkeyup event

function data_change(field)
{
var check = true;
var value = field.value; //get characters
for(var i=0;i < field.value.length; ++i)
{
var new_key = value.charAt(i); //cycle through characters
if(((new_key < "0") || (new_key > "9")) &&
!(new_key == ""))
{
check = false;
break;
}
}
if(!check)
{
field.style.backgroundColor = "red";
}
else
{
field.style.backgroundColor = "white";
}
}

function f2m(form)
{
var f = parseFloat(form.tlength.value);
var m = "";
if (!isNaN(f)) m = Math.round(f * 0.3048* 100)/100;
form.lm.value = m;
}

data_change(field) is also used by other textboxes, function f2m(form) is used only by one textbox.

i already tried combine them like onkeyup="return(data_change(this)&&f2m(this.form));"

any help please?

Hi

Make sure the first function returns true. The [tt]&&[/tt] will not evaluate the second term if the boolean expression's result is decided after the evaluating the first term. See Short-circuit_evaluation.

separate the two by a semi-colon:

<input type="text" onKeyUp="myFirstFuntion(params);mySecondFunction(params)" />
