altering values in forms - help please!

FluffyBiker · #1 Nov 12th, 2007, 19:58

Hey all, I'm a bit new to JavaScript so bear with me!

My main Website uses the Paypal buy it now buttons which i have found i can manipulate by using drop down menus.

What i Want to do now is capture 2 values from each option (one to alter the despcription one to alter the price) but i'm failing to succeed.

This is what I have (edited out the non relevant bits)

the code bit

HTML: Select all

 function hondachainselect()
{
document.hondachain.item_name.value = document.hondachain.hondachainproduct.value + document.hondachain.hondachain_bike.value 

}

the html form bit

<form target="paypal" action="xxxx" method="post" name="hondachain">

<b> Please Choose your colour:<br></b>
<select name="hondachain_bike" onChange="hondachainselect()">
    <option value=" 0 ">Choose Bike</option>
    <option value="CRF50 04-06" >CRF50 04-06 £19.99</option>
    <option value="CRF70 04-06" >CRF70 04-06 £19.99</option>
    <option value="CRF100 04-06" >CRF100 04-06  £29.99</option>
    
</select>

<br><font size="4"><b>from £19.99</b><br></font>
<input type="hidden" name="hondachainproduct" value="Chain & Sprocket Kit - ">

<input type="image" src="xxxxx" border="0" name="submit" >

<input type="hidden" name="item_name">
<input type="hidden" name="amount">

</form>

with that the "item_name" comes out correctly but I've given up how to get a 2nd value from the options to assign to "amount"

Many thanks in advance for your help!!

Hi

I think this is a paypal issue, i'm not sure but i think with a standard paypal buy it now button you can only pass the item name and price.

there are ways to pass multiple options but it gets complicated(well it was for me).
If you look at my site(contains adult material) and go through the process of add to basket and then checking out to paypal you will see that passing options is possible, however I have used php.

I'm already passing results from up to 3 drop downs and a hideen value to the "item_name"
just want to grab a related price from 1 drop down and pass that over too.

Trying to save 40 items on one page, If i can crack this it brings it down to just 4 items!

SOLVED!!!

with an array like this -

HTML: Select all

 function hondachainselect()
{
var bike = new Array(), bi=0;
bike[bi++] = {model:'CRF50 04-06', price:'19.99'};
bike[bi++] = {model:'CRF70 04-06', price:'19.99'};
bike[bi++] = {model:'CRF100 04-06', price:'29.99'};
bike[bi++] = {model:'CR85 R 03-04', price:'34.99'};

var bikevalue = document.hondachain.hondachain_bike.value;
document.hondachain.item_name.value = document.hondachain.hondachainproduct.value + bikevalue;
for (var bi=0;bi<bike.length;bi++)
  {
  if (bike[bi].model == bikevalue)
    {
    document.hondachain.amount.value = bike[bi].price;
    break;
    }
  }
}
