testWeb（jspackage.JSAssignmentDiscount）：正确的HTML组件div必须与适当的约束一起使用假的

根据上述“价格”约束使用以下行-

<input type="text" name="price" id="price" pattern="[\d]+" min="1" required>

您可以将此用于价格组件：

<input type="text" name="price" required pattern="[1-9]{1}[1-9]*">

应显示一个值为“获取折扣价格”的提交按钮。请看这一行。他使用了type=“button”，但应该是type=“submit”

实际上我现在也在问同样的问题。

我们不是来帮你做作业的。我不是来帮我解决这个问题，也不是来帮我做作业的。我已经按照规范解决了所有问题，但在评估时出现了一些错误，所以我只是澄清了我犯错误的地方。
