Document. Write () and document. writeln. --- Writeln () Why not wrap

Writeln () = write () + write ("\ n ");

However, in HTML parsing, only the </BR> line feed is parsed.

"\ N" is parsed into a blank space, and the blank space is parsed into a space.

Therefore, generally:

The difference between writeln () and write () is that the former has one more space.

 

In another case, writeln () will wrap

When the tag is in the <PRE> </PRE> <textarea> </textaera> label

HTML does not parse blank characters,The difference between writeln () and write () is that the former will wrap

Example:

Document. writeln ("<PRE> aaaaaaaaaa ");

Document. writeln ("aaaaaaaaaa ");

Document. writeln ("aaaaaaaaaa </PRE> ");

 

It may be easy to explain. You are welcome to point out the problem and add it.
