What does "/r" "/n" mean ???:(

Thanks a lot

I'm assuming you mean \r and \n. If so, they are the codes to add a line break.

[Adamli2000]

You mean both of them?
thanks

Well, they are a bit different. For example, in PHP, when working with files, \n is the *nix line break, while \r\n is the Windows line break... (Windows likes to be special...) For the most part, \n is what you need. In JavaScript, \n is a line break in an alert, etc...

We are using JavaScript to make a Rich Text Format component.
In the RTF,after editing the data, it will be stored in a database,and take it out to show when necessary. well, there is a function to transfer the format of the data before entering the database and after coming out the database. It is like this

String toHTML(String value) {
if ( value == null ) return "";
value = replace(value, "\r\n","<BR>&nbsp;&nbsp;&nbsp;&nbsp;");
value = replace(value, "\r","<BR>&nbsp;&nbsp;");
value = replace(value, "\n","<BR>&nbsp;&nbsp;");
return value;
}
String toHTMLother(String value) {
if ( value == null ) return "";
value = replace(value,"<BR>&nbsp;&nbsp;&nbsp;&nbsp;", "\r\n");
value = replace(value, "<BR>&nbsp;&nbsp;","\r");
value = replace(value,"<BR>&nbsp;&nbsp;", "\n");
return value;
}

My question is why they use such a transfer function instead of putting the data directly into the database? And how can "<BR>&nbsp;&nbsp;" take the place of "/r"

[pyro]

in HTML, <br> is the line break.

Also, they probably put it in the database using the \n or
\r line ending as it is more readable while in the DB that way.
