使用Jquery腳本進行復選框驗證

Question

如何使用此驗證腳本驗證複選框？ 我試過很多不同的方法無濟於事。這是一個驗證腳本，在我修改了我的目的的聯繫表單上，但無法弄清楚如何驗證chekboxes。這是我的表單和驗證代碼。

<form id="contactForm" action="send-mail.php" method="post"> 
    <table width="492"> 
     <tr> 
    <th><label>Title:</label></th> 
     <td><input name="title" id="title" type="text" class="form-poshytip" title="Enter your first name" /></td> 
      </tr> 
     <tr> 
    <th><label>Name:</label></th> 
     <td><input name="name" id="name" type="text" class="form-poshytip" title="Enter your first name" /></td> 
      </tr> 
       <tr> 
        <th><label>Email:</label></th>

Answer 1

只有一個複選框選中：

if (!$('input[name="checkbox[]"]').is(':checked')) { 
    $("#error").fadeIn().text("You must check at least one option."); 

    return false; 
} 

作爲。是的jQuery的文檔（）說：

Description: Check the current matched set of elements against a selector, element, or jQuery object and return true if at least one of these elements matches the given arguments.
