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

Thanks a lotI'm assuming you mean \r and \n. If so, they are the codes to add a line break.You mean both of them? 
thanksWell, 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","     "); 
value = replace(value, "\r","   "); 
value = replace(value, "\n","   "); 
return value; 
} 
String toHTMLother(String value) { 
if ( value == null ) return ""; 
value = replace(value,"     ", "\r\n"); 
value = replace(value, "   ","\r"); 
value = replace(value,"   ", "\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 "   " take the place of "/r"in HTML, 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.
