Well, since the table is dynamically generated, there obviously is a
time when you're in possession of the data that populates it. Why not
just add this data to a hidden field at time the same time as you're
generating a new row? Personally, I like to just keep the data in an
array, then redraw the whole table every time it changes. Makes it
easier when you need to remove an item.
Example:
var tickets = Array();
function add_ticket(id) {
tickets.push(id);
refresh_table();
save_to_hidden();
}
function refresh_table() {
var html = '';
for(var i = 0; i < tickets.length; i++) {
html += '<html here>';
}
table.innerHTML = html;
}
function save_to_hidden() {
hidden.value = tickets.join(',', tickets);
}
