paypal系列三:支付代碼

一: form送出
 
 
function paypalSubmit() {
 var paypalform;
 var formMain;
 var paypalendingUrl = "<% =HostUrl%>pay/Paypalending.aspx";
 var PaypalCancelUrl = "<% =HostUrl%>pay/PaypalCancel.aspx"

 if(itemname.length>4)

c#裡也可以用服務端代碼送出
private void Button1_Click(object sender, System.EventArgs e)
  {
   string postData = "";
   postData += "currency_code=USD";
　   postData += "&cmd=_xclick";
　   postData += ​​​&[email protected]​​​;
　   postData += "&upload=1";
　   postData += "&cancel_return="+HostUrl +"pay/Paypalending.aspx";
   postData += "&item_name=wowgn000255555";
   postData += "&quantity=1";
   postData += "&amount=280.23";
   postData += "&no_shipping=2";
　   byte[] data = Encoding.ASCII.GetBytes(postData);
   Response.Redirect("​​​https://www.paypal.com/cgi-bin/webscr?"+postData​​​);
  } <form  name="formPaypal" οnsubmit="return check()" action="​​https://www.paypal.com/cgi-bin/webscr​​​"
