JavaScript - How to pass/store value from function to form hidden field?

Question

Please, Im having an issue with the JavaScript below. I'm not very used to JavaScript... what I have below is a ticket booking script that displays the number of tickets selected, total amount and seat row / seat number. I want to pick the number of ticket, seat row, seat number ( for all the selected seat e,g 3,5 and 8,2 means row 3 seat 5 and row 8 seat 2) and amount in the HTML form HIDDEN FIELD as shown somewhere in the code and then send these values to another page through the submit button and then get them by PHP.

<div class="booking-details">
  <ul class="book-left">
    <li>Time </li>
    <li>Tickets</li>
    <li>Total</li>
    <li>Seats :</li>
 </ul>
 <ul class="book-right">        
    <li>: April 3, 21:00</li>
    <li>: <span id="counter">0</span></li>
    <li>: <b><i>$</i><span id="total">0</span></b></li>
 </ul>
 <div class="clear"></div>
 <ul id="selected-seats" class="scrollbar scrollbar1"></ul>


 <!-- HTML FORM WHERE HIDDEN INPUT IS LOCATED TO GET THE VARIABLES -->

            <div id="legend"></div>
        </div>
        <div style="clear:both"></div>
    </div>

如果必须将值传递给隐藏输入，可以像这样设置值：

$("#price").val(total);
