Remove Multiple New Lines with JavaScript
I'm blessed in that lots of people want to guest post on this blog. It's really flattering and I love seeing writers get a bunch of attention after writing. My task is converting the blog post, in whatever format it's provided in (HTML, Markdown, PDF, Google Doc, etc.), to HTML for my blog, which can sometimes get messy. I employ a host of regular expressions to fix these formatting issues. And the number one problem? Loads of extra new lines (\n).
The Regular Expression
The regular expression is actually quite simple:
content.replace(/[\r\n]+/g, '\n'); // Just one new line
content.replace(/[\r\n]+/g, '\n\n'); // "document" formatting, more elegant
With the dozens of extra lines gone it's much easier to work with the content!

One thing I love doing is duplicating OS functionalities. One of the things your OS allows you to do easily is move from one item to another. Most of the time you're simply trying to get to the next or the previous item.
![New York Times-Style Text Selection Widget Using MooTools or jQuery]()
Aaron Newton made a great request to me last week: why not make my MooTools Documentation Bookmarklet function more like the New York Time's text selection widget. NYT's text selection widget listens for text selection and presents the user with a "search" icon...
David,
I’m more inclined to use something like:
Only there always seems to be some extra whitespace between those newlines. If you don’t want to loose the tabs on the next line then this works just as well
