Find some sample text to play with below, from Bill Gates' speech at the MIX conference
"So, the theme, as I said, is about using software to reach out and create a new
customer experience, one that is valuable for the organization. This idea of both
attracting customers from the very beginning, retaining them, making it easy for
them to buy, make it easy to upsell them, building the community around them that
draws in other customers, this is a very hot area. In fact, there's best practices
all over the Web. I wouldn't say any one single Web site has all of these things
brought together. People who have always thought of their Web sites as their key
way to reach out to customers have been building that database, and for other companies
the idea of how you merge the different experiences that you might have, gather
that database, and personalize the experience based on things that happen outside
of the Web, that's very important as well."
DOM Range provides developers a standard way to select a piece of a document and
operate on it. The HTML5 Selection APIs allow this demo to extract the user selection
- and the Range behind it - for modification.
When you select text and click a command, code like the following gets executed:
Where execCommand() is a custom method defined off the Range prototype. Once the
method gets the Range corresponding to your selection, it passes the nodes inside
it to a callback, which in this case is the translation function. The callback modifies
the nodes, which the method then re-inserts into the document; this process is made
much easier by the fact that Range operates in terms of nodes to begin with.
