quick query, i notice i have 2 differnet pieces of code for ReadForm, can u clarify if they have different effects on output or just the same (each contains slight variations on formulas)....thanx
VERSION 1
function ReadForm (obj1) { // process un-named selects
var i,amt,des,obj,pos,val;
amt = obj1.baseamt.value*1.0; // base amount
des = obj1.basedes.value; // base description
for (i=0; i<obj1.length; i++) { // run entire form
obj = obj1.elements; // a form element
if (obj.type == "select-one" && // just get selects
obj.name == "") { // must be un-named
pos = obj.selectedIndex; // which option selected
val = obj.options[pos].value; // selected value
pos = val.indexOf ("@"); // price set?
if (pos >= 0) amt = val.substring (pos + 1)*1.0;
pos = val.indexOf ("+"); // price increment?
if (pos >= 0) amt = amt + val.substring (pos + 1)*1.0;
pos = val.indexOf ("%"); // percent change?
if (pos >= 0) amt = amt + (amt * val.substring (pos + 1)/100.0);
if (des.length == 0) des = val;
else des = des + ", " + val; // accumulate value
}
VERSION 2
function ReadForm (obj1) { // process un-named selects
var i,amt,des,obj,pos,val;
amt = obj1.baseamt.value*1.0; // base amount
des = obj1.basedes.value; // base description
for (i=0; i= 0) amt = val.substring (pos + 1)*1.0;
pos = val.indexOf ("+"); // price increment?
if (pos >= 0) amt = amt + val.substring (pos + 1)*1.0;
pos = val.indexOf ("%"); // percent change?
if (pos >= 0) amt = amt + (amt * val.substring (pos + 1)/100.0);
if (des.length == 0) des = val;
else des = des + ", " + val; // accumulate value
}
