Once again, I have an 11th hour code change. I had forgotten about
Jörn's suggestion of allowing additional passed arguments. I'm not
entirely sure what kind of implementation or usage was expected but I
added my own version. Any argument provided to the .doin()/.every()
function beyond the action function will be passed to the action
function as an argument. Hopefully that's what he was talking about.
Code Below:
jQuery.fn.extend({
every: function(interval,id,fn) {
var args = jQuery.map(arguments,"a"), slice = 3;
return this.each(function() {
var self = this;
interval = jQuery.speed(interval);
if (fn == undefined || id.constructor == Function) {
fn = id;
id = interval;
slice = 2;
}
if (!this.timers) this.timers = {};
if (!this.timers[id]) this.timers[id] = [];
this.timers[id].push(window.setInterval(function() {
fn.apply(self,args.slice(slice));
},interval));
});
},
doin: function(interval,id,fn) {
var args = jQuery.map(arguments,"a"), slice = 3;
return this.each(function() {
var self = this, counter = 0;
interval = jQuery.speed(interval);
if (fn == undefined || id.constructor == Function) {
fn = id;
id = interval;
slice = 2;
}
if (!this.timers) this.timers = {};
if (!this.timers[id]) this.timers[id] = [];
this.timers[id].push(window.setInterval(function() {
if (counter++ >= 1) return jQuery(self).stop(id);
fn.apply(self,args.slice(slice));
},interval));
});
},
stop: function(id) {
return this.each(function() {
if (!this.timers) return;
if (id == undefined)
jQuery.each(this.timers, function(i) {
jQuery.each(this,function(j) {
window.clearInterval(this);
});
});
else if (this.timers[id])
jQuery.each(this.timers[id],function(i) {
window.clearInterval(this);
});
});
}
});
