How to start a new line from JavaScript?

Question

I have created this "shell" in jQuery:

Code: link text

Demo: link text

I need that every 100 chars, the prompt go in a new line below. How can I do this ?

Answer 1

At a high level, you're generating html from JavaScript, so any html which would work standalone will work when generated from JavaScript too. Some possibilities, with varying flexibility:

Pre-formatted text, insert newline "\n" characters:

<pre>
line one
line two
</pre>

Inserting break tags:

line one<br />
line two<br />

Or my favourite, use paragraph tags:

<p>line one</p>
<p>line two</p>

I like this because you can refer to each line in code as a single DOM element. Set this css to keep the lines side-by-side:

div.code-listing p { margin: 0; padding: 0; }

Answer 2

Programaticaly, by concatenating <br /> is the only way I can think of.

word-wrap: break-word;

Combined with a width should give you an approximation, but it won't be perfect.
