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 $(this).show(); } ); console.log('Time: ' + ((new Date).getTime() - jqStart)); } ); However, there was a couple of seconds delay after typing each letter (particularly the first letter). So I thought it may be slightly quicker if I used plain Javascript (I read recently that jQuery's each function is particularly slow). Here's my JS equivalent: document.getElementById('filter').addEventListener( 'keyup', function () { var jsStart = (new Date).getTime()...
No problem. Just use the following. This will behave exactly like serializing a form but using a div's content instead.
ReplyDelete$('#divId *').serialize();
Check http://jsbin.com/azodo for a demonstration (http://jsbin.com/azodo/edit for the code)
You can improve the speed of your code if you restrict the items jQuery will look at.
ReplyDeleteUse the selector :input instead of * to achieve it.
$('#divId :input').serialize()
This will make your code faster because the list of items is shorter.
Try also this:
ReplyDelete$('#divId').find('input').serialize()
jitter's solution helped me from a more generic viewpoint. Clicking a link, finding it's parent div and then serializing:
ReplyDelete//$(this) is a "click"able item within the div
var divid = $(this).closest('div').attr('id);
var data = $('#'+ divid+ ' *').serialize();
