听起来你已经解决了这个问题，但为了正确的上下文：以下是Mitchel Sellers关于主题的博客文章：

To include an HTML form within DNN you will first need to note the "Action" property that is set in the tag. Once you know this action you will want to remove the opening and closing form tags. Now, in the HTML source location the submit button ( or similar) . Then add the following inside the tag declara tion.

onClick="this.form.action= YourUrlHere ;this.form.submit();" Be sure to put your Action URL inplace of the "YourUrlHere" text. This tells the HTML form that if the submit button is clicked that it should change the form action, which will prevent ASP.NET postback and then it actually submits the form to the new URL.

This provides you a quick and reliable method to submit HTML forms to external sites. This isn t the best solution as other input items on the current page will be submitted to the action page, however, typically that is not too large of an issue.

下面是我使用jQuery提出的一个更为复杂的方法/示例，它应该专门解决您的问题：

<p class="item">
  Buy <span class="name">A Product</span> for $<span class="price">9.99</span>
  <input type="image" src="https://www.paypal.com/en_US/i/btn/btn_cart_SM.gif" style="border:solid 0px black;" name="submit" alt="click here to order">
</p>

$( p.item input[type=image] ).click(function(){
  var $itemDetail = $this.parent( p.item );
  var name = $itemDetail.find( .name ).val();
  var price = $itemDetail.find( .price ).val();
  window.open( https://www.paypal.com/cgi-bin/webscr?cmd=_cart&business=youremail%40address.com&item_name=  + name  +  &amount=  + price +  &no_note=1&currency_code=USD&add=1 ,  yourcartwindowname );
});

这种方法的重要特征是为您提供一个html“模板”，该模板可以重复使用，并可用于每个项目。它还会在一个新窗口中打开PayPal购物车页面，如果用户在购物车中添加了多个项目，它会保持同一窗口。非常简单但相对快速且易于实现，如果您可以依赖JavaScript实现此功能的话。
