You could try the .text()method if you're using jQuery.

The value of span is added to the input field of id="sub". you may use any events for assign values to hidden fields like click, change, submit, or you do as your logic .its an option.
span 的值添加到 id="sub" 的输入字段中。您可以使用任何事件为隐藏字段分配值，例如单击、更改、提交，或者您按照逻辑进行操作。这是一个选项。
$("#sub").val($("#subtotal").text());
<span id="subtotal"></span>
<input type="hidden" id="sub" >

Should'nt you be having subtotalinstead of totalthere?
你不应该在那里subtotal而不是在total那里吗？
function getTotal() {
return alert(document.getElementById('subtotal').innerHTML);
}
