If that was the case, jQuery("#main a").filter(function() { return false;

Hm... I also tested this and filter didn't prune the list with my function
returning false.
Here's the filter function out of 1.0.3 which checks if t is a function and
pushes the result of jQuery.grep(this, t) onto the stack.
filter: function(t) {
return this.pushStack(
*SNIP*
typeof t == "function" &&
jQuery.grep( this, t ) ||
jQuery.filter(t,this).r, arguments );
},
Now in the grep function it operates on the list of elements in elms. It
calls the function we defined (fn) and if fn returns false it shouldn't add
them to the result array.
grep: function(elems, fn, inv) {
*SNIP*
var result = [];
// Go through the array, only saving the items
// that pass the validator function
for ( var i = 0; i < elems.length; i++ )
if ( !inv && fn(elems[i],i) || inv && !fn(elems[i],i) )
result.push( elems[i] );
return result;
},
Am I missing something here?
Cheers,
