Weird syntax for extending jQuery
- by cantabilesoftware
I recently saw this code on another post ( http://stackoverflow.com/questions/499126/jquery-set-cursor-position-in-text-area )
new function($) {
$.fn.setCursorPosition = function(pos) {
// function body omitted, not relevant to question
}
} (jQuery);
After too long trying to understand what it was doing I finally figured out that it's just creating a new function with a parameter $ and then invoking it with jQuery as the parameter value.
So actually, it's just doing this:
jQuery.fn.setCursorPosition = function(pos) {
// function body omitted, not relevant to question
}
What's the reason for the original, more confusing version?
