c# - 警报弹出窗口中的换行符

Question

我正在尝试添加新行 Javascript 警报消息。我尝试了“\n”和“Environment.NewLine”。我收到未终止的字符串常量错误。你能告诉我可能是什么问题吗？我感谢任何帮助。我也试过\r\n。

string msg = "Your session will expire in 10 minutes. \n Please save your work to avoid this.";


if (!this.ClientScript.IsStartupScriptRegistered(ID)) 
   this.ClientScript.RegisterStartupScript(GetType(), ID, String.Format("<script language=JavaScript>setTimeout(\'alert(\"{1}\");\',{0}*1000);</script>", sTime, msg));

Answer 1

我怀疑您需要将代码更改为；

string msg = "Your session will expire in 10 minutes. \\n Please save your work to avoid this.";

并转义 \n 否则你输出的代码实际上会包含换行符而不是 \n

您的输出代码如下所示:

setTimeout('alert("Your Session....
 Please save your work to ....");', 1000);

而不是:

setTimeout('alert("Your Session....\n Please save your work to ....");', 1000);
