Live.js - One script closer to Designing in the Browser
|
||||
Written for Handcraft.com by Martin Kool (@mrtnkl).
|
||||
|
||||
Version 4.
|
||||
Recent change: Made stylesheet and mimetype checks case insensitive.
|
||||
|
||||

@livejs
|
||||
|
||||
Include live.js#css to monitor css changes only.
|
||||
Include live.js#js to monitor js changes only.
|
||||
Include live.js#html to monitor html changes only.
|
||||
Mix and match to monitor a preferred combination such as live.js#html,css
|
||||
|
||||
By default, just include live.js to monitor all css, js and html changes.
|
||||
|
||||
Live.js can also be loaded as a bookmarklet. It is best to only use it for CSS then,
|
||||
as a page reload due to a change in html or css would not re-include the bookmarklet.
|
||||
To monitor CSS and be notified that it has loaded, include it as: live.js#css,notify
