[Guest]

hey all,

i have two textboxes on a webform that are inputs for numbers.
using client-side script (any language) how would i add the values together
and put in another textbox or variable?

thanks,

var input1 = document.getElementById("input1");
var input2 = document.getElementById("input2");
var total = document.getElementById("input3");
//this is a regular expression to verify the inputs are real number
if (/^(\+|-)?\d+(\.\d+)?$/.test(input1.value) &&
/^(\+|-)?\d+(\.\d+)?$/.test(input2.value) )
{
total.value=parseFloat(input1.value)+parseFloat(input2.value);

}
