Generate jquery array so I can use ++arrayname[i]; [closed]

I want to generate a basic array and declare it with a 'n' number of elements in jquery. I want to initialize each value of the array with 0 and I want to be able to call increment each value of the array. How can I do it?
I have a HTML list of about 500 items and a "filter" box above it. I started by using jQuery to filter the list when I typed a letter (timing code added later): $('#filter').keyup( function() { var jqStart = (new Date).getTime(); var search = $(this).val().toLowerCase(); var $list = $('ul.ablist > li'); $list.each( function() { if ( $(this).text().toLowerCase().indexOf(search) === -1 ) $(this).hide(); else $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
If I understand, you need something like that:
ReplyDeleteTo initialize:
$.each(arrayname, function(idx, elt) {
arrayname[idx]=0; // **EDIT**
});
To increment:
$.each(arrayname, function(idx, elt) {
arrayname[idx]++; // **EDIT**
});
