@Thijs: thanks for a positive contribution. It seems few of us will
have to "get together" and try and do this in parallel with the main-
stream.
@dz: At last a number for you ;o) Andrea says that IE versions of jQ
are 10 times slower ...
@Andrea: Agreed. Although conceptually I am proposing to use JScript
conditional comments.
// Step 1 : one file
inArray = function( elem, array ) {
return array.indexOf(elem);
}
/*...@cc_on
inArray = function( elem, array ) {
for ( var i = 0, length = array.length; i < length; i++ )
{
if ( array[ i ] === elem )
return i;
};
return -1;
}
@*/
Seems cleaner? And/Or the next step with 2 files :
jquery.2.js :
-------------
inArray = function( elem, array ) {
return array.indexOf(elem);
}
jquery.2.IE.js
---------------
inArray = function( elem, array ) {
for ( var i = 0, length = array.length; i < length; i++ )
{
if ( array[ i ] === elem )
return i;
};
return -1;
}
(to be included with IE HTML conditional comments)
Of course this is all very interesting and a very big job. Step 1 (one
file ) has its drawbacks, but issues in step 2 do mushroom
exponentialy: client or server side compostion, why and how etc ..
Server side composition gives more elegant client code, but then it
requires a server side:
<script src="http://your.server.here/jquery2.php"; ></script>
Above is pehaps nice, but it excludes local simple usage of jquery.js
as we have it now.
There are few valid ways to implement the composition and delivery
mechanism. And none is "perfect" of course. The "big job" is in the
process of breaking up jQuery into small discrete parts which can be
used to compose many different versions, in acordance with browser AND
in accordance with the capabilities of the browser. This would require
some non-trivial coding, that is for sure.
