[jQuery] $().get() returns elements in reverse order in 1.2.5, 1.2.6
Is this a bug or simply a change in functionality I should be prepared
to cope with?
This code
------------------
<script src="http://jqueryjs.googlecode.com/files/jquery-1.2.5.js"></
script>
<span>1</span><span>2</span><span>3</span>
<script language=JavaScript><!--//
$(function() {
var arr=$("span").get();
var txt=[];
for(ai in arr) { txt.push(arr[ai].innerHTML); }
alert("via get(): "+txt.join(","));
$("span").each(function(i,o) { alert("via each #"+i
+".html="+o.innerHTML); });
});
//--></script>
------------------
Will alert you "via get(): 3,2,1", however the each loop will report
the innerhtmls of the elements in order 1,2,3. Earlier versions of
jquery (1.2.4 and lower) will report "via get(): 1,2,3".
Although the order of elements is not specified in the documentation,
I think that expecting them to be returned in document order is the
only rational behavior. Is this an unintentional change?
It seems to boil down to a change in how the array is constructed in
makeArray. In 1.2.4 it was done in order via:
------------------
for ( var i = 0, length = array.length; i < length; i++ )
ret.push( array[ i ] );
------------------
whereas in 1.2.5 and 1.2.6 it is done by more consise, but reversing:
------------------
while( i )
ret[--i] = array[i];
------------------
A simple way to fix this would be to insert "ret.reverse()" just
before ret is returned.
If there is somewhere I could have noted this as an existing bug or an
intentional change, I am sorry, I have looked all over. Let me know
where I should have looked.
Thanks!
