Javascript attribute to ASP.net button web control

Question

Hi,

I have a rather pesky problem when trying to add a confirm popup message to the onclick event of a button.

The problem occurs when trying to break the message onto a new line so the test wraps within the pop up window. If the \n is taken out of the string the code works fine.

string confirmationMessage = "text text text text text text text text text text text text text text text text text text \n text text text text ";

submitButton.Attributes.Add("onclick", "return confirm('" + confirmationMessage + "');");

Any help is apprciated thank you.

Not sure whether to post a separate question for this. I have a new problem but there seems to be a limit to to amount of text i can include. If the string is too long the confirmation message fails to display.

Answer 1

I think your problem is about escape character, try this :

string confirmationMessage = "text text text text text text text text text text text text text text text text text text \\n text text text text ";

// or : 
// string confirmationMessage = @"text text text text text text text text text text text text text text text text text text \n text text text text ";

submitButton.Attributes.Add("onclick", "return confirm('" + confirmationMessage + "');");

The compiler is probably evaluating the escape sequence instead of treating it as plain text. Add an "@" in front of the string and see if that works:

string confirmationMessage = @"text text text text text text text text text text text text text text text text text text \n text text text text ";
