php - How to send serialize form data using JQuery if the input element is an array

Question

I have this piece of code in my PHP code:

while ($row = mysqli_fetch_assoc($result))
{
    extract($row);
    echo "<tr>";
    echo "<td bgcolor='#FFFFFF'><input id='bookArray[]' name='bookArray[]' type='checkbox' value='$book_id' />$book_id</td>";
    echo "<td bgcolor='#FFFFFF'>$threat_name</td>";
    echo "</tr>";
}

In HTML page, I want to use jQuery serialize() method to sent array of selected books in bookArray[]. In my JavaScript,

var selectedbooks = $("book_form").serialize();
alert (selectedbooks); 

In the alert message box, i did not get any value (empty string).

Previously when i am using Prototype, it worked nicely.

Answer 1

easy: serialize().replace(/%5B%5D/g, '[]')
