Javascript output USD values via Paypal, Simply form outputting USD values to a paypal "add to cart" Options

[oddjobmj]

Hello,

I am attempting to get a pre-existing javascript to output its data to a paypal shopping cart.

The script asks for two values - and then spits out a USD value and an estimated time of completion. I need the USD value to be sent to paypal through their e-commerce package. I have set up quite a few static "add to cart" buttons through paypal already. It has gone very well, but I cannot manage to get this dynamic output to function properly.

So, I'll go ahead and post my javascript here.

CODE

    function Item(level,time,price) {
        this.level    = level;
        this.time    = time;
        this.price    = price;
    }

Here is an example of one of the paypal "add to cart" buttons.

CODE

<a href="#" onMouseOut="MM_swapImgRestore()" onMouseOver="MM_swapImage('Order Now!','','images/order_ordernow_rollover_09.jpg',1)"><div align="right"><form target="paypal" action="https://www.paypal.com/cgi-bin/webscr" method="post">
<input type="image" src="http://www.platinum-leveling.com/images/addtocart.gif" border="0" name="submit" alt="PayPal - The safer, easier way to pay online!">
<img alt="" border="0" src="https://www.paypal.com/en_US/i/scr/pixel.gif" width="1" height="1">
<input type="hidden" name="add" value="1">
<input type="hidden" name="cmd" value="_cart">
<input type="hidden" name="business" value="Payment@platinum-leveling.com">
<input type="hidden" name="item_name" value="Custom Power Leveling">
<input type="hidden" name="item_number" value="10">
<input type="hidden" name="amount" value="140.00">
<input type="hidden" name="no_shipping" value="1">
<input type="hidden" name="return" value="http://www.platinum-leveling.com/contact/thankyou.php">
<input type="hidden" name="logo_custom" value="http://www.platinum-leveling.com/images/viewcart.gif">
<input type="hidden" name="currency_code" value="USD">
<input type="hidden" name="lc" value="US">
<input type="hidden" name="bn" value="PP-ShopCartBF">
</form></div></a>

I essentially want

CODE

price        = price + ItemArr[i].price;

(Or atleast, the "price" part - whatever that would be)

in my javascript to replace "140.00" in my paypal button code.

CODE

<input type="hidden" name="amount" value="140.00">

That way, whenever someone enters their values and gets a quote, they can add that value to their paypal cart.


Here is a link to the page with the javascript forms working.

Whether I use the "continue" or "order now" button isn't important to me.
Any suggestions?

Thank you for your time!

Heyy, I fixed it with a little help from a buddy of mine. It's not too rough, either. For anyone that strolls across this thread... Here we go-

I simply added

CODE

document.getElementById('paypal-value-input').value = form.price.value;

to the end of the javascript, right after

CODE

form.totaltime.value    = totaltime;

then to pull that value from there to the button I changed the value in the button from

CODE

<input type="hidden" name="amount" value="140.00">

to

CODE

<input type="hidden" name="amount" id="paypal-value-input">

Woo, there it goes!
