Javascript to make some links blink

Mark each anchor tag (<a href…) with rel=”blinking” to make the tag blink (not very clever, but sometimes useful).

This code uses prototype.js function “$$”.

function blinking() {
	var a = $$('a[rel="blinking"]');
	var t = 50;
	for (i=0 ; i < a.length;  i++) {
		if (a[i].style.visibility=='hidden') {
			a[i].style.visibility='visible';
			/* stays on for 2 seconds */
			t = 2000; 
		} else {
			a[i].style.visibility='hidden';
			/* stays off for 50 milliseconds */
			t = 50;
		}
	}
	setTimeout("blinking();",t);
}
