c# - 无法在确认框中使用 \n 获取新行

Question

下面是我的代码

btnDelete.Attributes.Add("onclick", "{return ConfirmAction('You are about to Delete Order . Please Note \r\n  1. Order no longer can be retrieved \r\n 2. Changes to the order are not saved. \r\n Are you sure you wish to continue to Delete?')};");

我希望确认框显示带有是和取消按钮的消息，如下所示：

您即将删除订单。请注意： 1.订单无法
找回
2.订单更改未保存
您确定要继续删除吗？

我尝试了 "\n" 、 '\n' 和 "\r\n" ，但仍然无法插入行。

Answer 1

您在字符串中有一个字符串，因此您需要转义反斜杠：

btnDelete.Attributes.Add("onclick", "{return ConfirmAction('You are about to Delete Order . Please Note \\n  1. Order no longer can be retrieved \\n 2. Changes to the order are not saved. \\n Are you sure you wish to continue to Delete?')};");

Answer 2

String buttonString = "{return ConfirmAction('You are about to Delete Order . Please Note \r\n  1. Order no longer can be retrieved \r\n 2. Changes to the order are not saved. \r\n Are you sure you wish to continue to Delete?')};"
buttonString = buttonString.Replace("\r\n", Environment.NewLine);
btnDelete.Attributes.Add("onclick", buttonString);

我不知道您正在使用的组件，但是您尝试过<br />吗？如果它接受 HTML，那可能会起作用:)
