DRY and Pythonic jQuery?
Monday, November 30th, 2009
Apparently, groovy:spring:java as jabs:jquery:javascript. As if jQuery wasn’t short enough already.
Jabs lets you write this jQuery code:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 | jQuery(function() { var $ = jQuery; $("[default_value]") .blur(function() { var self = $(this); if(self.val() === "") { self.val(self.attr("default_value")); } }) .focus(function() { var self = $(this); if(self.val === self.attr("default_value")) { self.val(""); } }) .blur(); }); |
By typing this:
1 2 3 4 5 6 7 8 | $ [default_value] :blur if @value === "" @value = @default_value :focus if @value === @default_value @value = "" .blur |
HAML tactics FTW.
Hey, I've noticed, thanks to your post, that the Jabs readme file is showing those two examples incorrectly. I've updated the text at http://github.com/collin/jabs
Thanks man! I updated my post.
Great stuff, btw. I love it. Idk if i'll use it, but it's really awesome.
