//You can use flags and based upon the flag set disability of your button

var length_valid = 0;
var txt_valid = 0;

if (m!=0)
{
length_valid = 0;
... //Other code
}
else
{
length_valid = 1;
.. //Other code
}
if(maxTxtVal < 0)
{
txt_valid = 0;
... //Other code
}
else
{
txt_valid = 1;
... //Other code
}

if(length_valid && txt_valid)
{
document.getElementById ("submit").disabled = false;
}

document.getElementById ("submit").disabled = true ;
