如何在paypal表单中添加金额

Question

我想从我的网站插入var permute = (nums) => { results = []; var backtrack = (nums, result) => { if (nums.length === result.length) { results.push(result); } else { for (var i = 0; i < nums.length; i++) { if (result.indexOf(nums[i]) > -1) { continue; } result.push(nums[i]); backtrack(nums, result); result.pop(); } } } backtrack(nums, []); return results; }; console.log(permute([1, 2, 3]));到Amount，然后点击PayPal form按钮。

Submit，item_name都是PayPal网站上的显示，但quantity是空的？我需要在Price per item

中添加Price per item任何金额

HTML表格

amount field

我有尝试金额而非金额_1 PayPal显示错误消息

尝试使用amount代替amount_1

<input type="hidden" value="6.99" name="amount">
