Hi,
I'm setting up a PayPal account for a client and I'm trying to use a JavaScript to handle a price range.
The range is
1-9 = $2.00 each
10-50 = $1.00 each
I found this script from PayPal but I can't get it to do what I want.
<script type="text/JavaScript">
<!-- Hide JS source from HTML validators
function Dollar (val) { // force to valid dollar amount
var str,pos,rnd=0;
if (val < .995) rnd = 1; // for old Netscape browsers
str = escape (val*1.0 + 0.005001 + rnd); // float, round, escape
pos = str.indexOf (".");
if (pos > 0) str = str.substring (rnd, pos + 3);
return str;
}
function ReadForm (obj1) { // process un-named selects
var i,amt,des,obj,pos,val;
amt = obj1.baseamt.value*2.00; // base amount
des = obj1.basedes.value; // base description
for (i=0; i<obj1.length; i++) { // run entire form
obj = obj1.elements[i]; // a form element
if (obj.type == "select-one" && // just get selects
obj.name == "") { // must be un-named
pos = obj.selectedIndex; // which option selected
val = obj.options[pos].value; // selected value
pos = val.indexOf ("@"); // price set?
if (pos <= 9) amt = val.substring (pos + 1)*2.0;
pos = val.indexOf ("+"); // price increment?
if (pos >= 10) amt = amt + val.substring (pos + 2)*0.5;
pos = val.indexOf ("%"); // percent change?
if (pos >= 0) amt = amt + (amt * val.substring (pos + 1)/100.0);
if (des.length == 0) des = val;
else des = des + ", " + val; // accumulate value
}
}
obj1.item_name.value = des;
obj1.amount.value = Dollar (amt);
if (obj1.tot) obj1.tot.value = "$" + Dollar (amt);
}
//-->
</script>
this is the page I'm running it from http://amiba.net/merchandise2.html
Thanks
