Question

很抱歉......我使用的是一个可以有一行或多行的ASP.NET列表视图。这是为listview本身生成的HTML。我希望能够相互减去名为txtAmount和txtPayAmt的两个INPUTS，这样我就可以向客户发送消息，告知他们是否已准备好支付已经零余额的账户。

感谢您提供的任何帮助。

我是使用jQuery的新手，因此我将自己置于开发人员的怜悯之下，寻求有关此问题的帮助。我需要在列表视图中迭代一行或多行，同时从另一行中减去行中一个文本框中的数量。我一直试图想出这一天，但没有运气。请帮忙！

您可以使用ListViewItem的查找控件方法来查找控件。将控件转换为文本框，然后获取值。

然而，通过检查ItemDatabound事件中的Item以查看是否存在零余额然后将js onclick添加到复选框（如果已选中），然后使用警报点击它们，可以更好地服务。
