When I display the result from a TEXTAREA in a Web page, the line breaks are removed. How can I maintain a TEXTAREAs line breaks in an Web page?

[Print this FAQ]

Answer: When a user is entering text into a TEXTAREA (multi-line text box) control, the carriage returns are not displayed when you view the user's inputted text through a Web page. For example, create an ASP page that has a form with a TEAXTAREA:

  Enter some text:<BR>


Then, in SomeOtherPage.asp (where the form sends the user when the above form is submitted), output the value of the TEXTAREA:

  Response.Write Request("MyTextBox")

Now, if the user entered some text into the TEXTAREA that contained line breaks, like:

These line breaks won't appear when the value of the TEXTAREA is displayed in SomeOtherPage.asp. You'll see:
Hello World!

This is because when a user enters a carraige return in the TEXTAREA, a simple vbCrLf (or carraige return) is entered. Carraige returns are skipped over when parsing HTML... If you want to force a linebreak in HTML, you must use the <BR> tag. Therefore, to maintain the line breaks entered by the user in the TEXTAREA, you must first replace all the carraige returns (vbCrLf) with <BR> tags. You can use the Replace function to do this!

In SomeOtherPage.asp, to maintain the formatting, you'd want to do:

  Response.Write Replace(Request("MyTextBox"), vbCrLf, "<BR>")

Note that the above snippet of code simply says, "Hey, where are the vbCrLf's in the user's TEXTBOX entry? Wherever you find them, replace them with <BR>! Thanks!" And with that simple line of code, we've maintained line breaks in a TEXTAREA! Neat, eh?

For more information on the Replace function, be sure to read the technical docs.

Happy Programming!
