I'm with you there. You know how I love to simplify code. If I learned that you didn't have to say .length to get the length, then the very next thing I'd do would be to try to simplify this code that I write so often: var $foo = $('.foo'); if( $foo.length ) { // got some elements } by changing it to: var $foo = $('.foo'); if( $foo ) { // got some elements } :-( Ah well, nice idea, wasn't it. :-) -Mike p.s. Too bad there's no .booleanOf() or .toBoolean() method in JavaScript - then we could do this right!
_____ From: John Resig I'm hesitant to add that (I've definitely thought about it, in the past) because .valueOf() doesn't cover all comparison cases. obj > obj2 works (as you noted) but if ( obj ) {} doesn't (it always returns true) Additionally, in Firebug, the result shows up as a number rather than something more useful (like a list of elements). --John On Thu, Jul 23, 2009 at 2:06 PM, James Padolsey <jamespadol...@googlemail.com> wrote: Just a thought; this would be quite useful IMO: var paras = $('p'), uls = $('ul'); if (paras > uls) { // ... } I know it's not quite as readable (or as semantic) as: if (paras.length > uls.length) { // ... } but still, it's one of those things that may as well be added, just for the few situations where it may be useful. jQuery.fn.valueOf = function(){return this.length;}; Unless it's got some other valid use (with jQuery)...? --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "jQuery Development" group.
