Question

请问，我在下面的JavaScript中遇到问题。我不习惯JavaScript ...我在下面的是一个票务预订脚本，显示所选票证的数量，总金额和座位行/座位号。我想选择机票，座位排，座位号码（所有选定的座位e，g 3,5和8,2表示第3排座位5和第8排座位2）和HTML表格中的数量HIDDEN FIELD as显示在代码中的某个位置，然后通过提交按钮将这些值发送到另一个页面，然后通过PHP获取它们。

<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 -->

如果必须将值传递给隐藏输入，可以设置如下值：

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

JavaScript - 如何从函数传递/存储值以形成隐藏字段？
