color=#0000ff size=2>If the last arg to pushStack is a function, it does
.each(fn) with the filtered set but returns the original set.
</FONT></SPAN><SPAN class=925510822-14122006><FONT face=Arial color=#0000ff
size=2>If there are two trailing function args, the first is treated as above.
However, if the filtered set returned nothing (and thus fn was never called) it
does .each(fn2) with the original set. Kind of like an if-then-else. It's never
been documented but I think it will be eventually.</FONT></SPAN></DIV>

was the case, jQuery("#main a").filter(function() { return false; }) would
return nothing. But it doesn't. It returns the original group of elements. At
least for me.<BR><BR>Hm... I also tested this and filter didn't prune the list
with my function returning false. <BR><BR>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.<BR><BR>filter: function(t) {<BR>   
    return this.pushStack(<BR>   
        *SNIP*<BR><BR>

jQuery.grep( this, t ) || <BR><BR>       
    jQuery.filter(t,this).r, arguments );<BR>   
},<BR><BR>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. <BR><BR>grep: function(elems, fn, inv)
{<BR>        *SNIP*<BR>   
    var result = [];<BR><BR>       
// Go through the array, only saving the items<BR>   
    // that pass the validator function<BR>   
    for ( var i = 0; i < elems.length; i++
)<BR>            if ( !inv
&& fn(elems[i],i) || inv && !fn(elems[i],i)
)<BR>               
result.push( elems[i] );<BR><BR>        return
result;<BR>    },<BR><BR>Am I missing something here?
