Jquery: most efficient way to get and store ids from 100 + td elements?

So, I have about six such calendars per page, which is about 180 td (1 for each date):

each td has an ID equal to that time of day. the dates I want are red (class .booked

).

So I need the fastest way to "serialize" IDs for items, td.booked

on td.booked

, any ideas?

You can get an array of IDs using .map()

for example:

var ids = $("td.booked").map(function() { return this.id; }).get();


This will result in an array like this:

["id1", "id2", "id3", ... ]

What exactly do you mean by serialization?



If they are tagged on the client, then the fastest way to collect links to them is to collect them as they are tagged. Then you already point to them when you need it, and no retroactive requests are required.

How about this:

var str = '';

$(function(){
  $('td.booked').each(function(index){
     str += '&td' + index + "=" + encodeURIComponent($(this).text());
  });
});

alert(str);
