HTML複選框返回值？

下面是我的代碼，我試圖讓它顯示順序的結果，但是我不能讓它出現，我相信複選框的返回值可能不是真實的，所以我嘗試使用var checkedt5 = $("t5").is(':checked');，但我得到onclick on order不起作用的錯誤。我相信這是功能上的錯誤。HTML複選框返回值？

<html> 

<head> 
    <title>Form </title> 

<script LANGUAGE="JavaScript"> 
<!-- hide from uneducated browsers 
function Order() 
{ 
    var size = document.getElementById("pizzasize").value 
    var crust = document.getElementById("pizzacrust").value 
    var t1 = document.getElementById("t1").value 
    var t2 = document.getElementById("t2").value 
    var t3 = document.getElementById("t3").value 
    var t4 = document.getElementById("t4").value 
    var t5 = document.getElementById("t5").value 
    var checkedt1 = $("t1").is(':checked'); 
    var checkedt2 = $("t2").is(':checked'); 
    var checkedt3 = $("t3").is(':checked'); 
    var checkedt4 = $("t4").is(':checked'); 
    var checkedt5 = $("t5").is(':checked'); 



    document.write("<p>") 
document.write("Your order is in process <br /> ") 
     document.write("Pizza Size = " + size + "<br />") 
     document.write("Pizza Crust = " + crust + "<br />") 
if (checkedt1 == true) 
{ 
document.write("Toppings = " + t1 + "<br />") 
} 
if (checkedt2 == true) 
{ 
document.write("Toppings = " + t2 + "<br />") 
} 
    if (checkedt3 == true) 
    { 
document.write("Toppings = " + t3 + "<br />") 
} 
    if (checkedt4 == true) 
    { 
document.write("Toppings = " + t4 + "<br />") 
} 
    if (checkedt5 == true) 
    { 
document.write("Toppings = " + t5 + "<br />") 
} 
    document.write("Your order will be delivered as soon as possible") 

    return "" 
    }

你錯過了# for selecting by id

var checkedt1 = $("#t1").is(':checked'); 
var checkedt2 = $("#t2").is(':checked'); 
var checkedt3 = $("#t3").is(':checked'); 
var checkedt4 = $("#t4").is(':checked'); 
var checkedt5 = $("#t5").is(':checked');

我已經加入＃到每個所要求的要素，但是，我仍然無法運行 – user2951224

@ user2951224包括jQuery的在你的頁面。 – Musa

@Musa會不會這樣工作？ – user2951224
