JavaScript警報功能中的HTML標簽

Question

這是我的aspx.cs代碼：

string script = "alert('Dosya/Dosyalar Başarı İle Yüklendi\n " + btnUpload.FileName + " ');";
ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script, true);

但是它不起作用。（無錯誤）當我刪除\\ n運算符時，它的工作警報功能。 我想在文本下方看到文件名

我怎樣才能做到這一點？

Answer 1

嘗試\\ r \\ n換行：

string script = "alert('Dosya/Dosyalar Başarı İle Yüklendi \\r\\n " + btnUpload.FileName + " ');";
ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script, true);

喬恩·斯基特（Jon Skeet）早在2004年的C＃轉義序列中

C# defines the following character escape sequences:

\' - single quote, needed for character literals
\" - double quote, needed for string literals
\\ - backslash
\0 - Unicode character 0
\a - Alert (character 7)
\b - Backspace (character 8)
\f - Form feed (character 12)
\n - New line (character 10)
\r - Carriage return (character 13)
\t - Horizontal tab (character 9)
\v - Vertical quote (character 11)
\uxxxx - Unicode escape sequence for character with hex value xxxx
\xn[n][n][n] - Unicode escape sequence for character with hex value nnnn (variable length version of \uxxxx)
\Uxxxxxxxx - Unicode escape sequence for character with hex value xxxxxxxx (for generating surrogates)

Answer 2

您可以使用System.Environment.NewLine代替\\ n。 例：

string script = "alert('Dosya/Dosyalar Başarı İle Yüklendi "+ System.Environment.NewLine + btnUpload.FileName + " ');";
ClientScript.RegisterClientScriptBlock(this.GetType(), "Alert", script, true);
