$.filedownload in javascript gives '$ is not defined'

Question

I am very new to jquery and js but have this code in myphp.php file:

<?php
echo "<div><tr><a href='javascript:getspreadsheets();'>Cape Culture (10 years)</a></tr><br />";
echo "<tr><a href='javascript:getspreadsheets();'>Winsters (5 Years)</a></tr><br />";
echo "<tr><a href='javascript:getspreadsheets();'>Kayo (1 year)</a></tr><br />";
echo "<tr><a href='javascript:getspreadsheets(1498);'>Col Timbers</a></tr></div>";
?>

  <script type="text/javascript">
function getspreadsheets(val)
{
    alert(val);
    var self = this,

        activityguid = self.activityguid,
        accountguid  = self.accountguid

        $.fileDownload(
            'data/export.items_to_csv.php',
            {
                httpMethod: 'POST',
                data: {
                    activityguid : activityguid,
                    accountguid  : accountguid,
                    classid      : val
                }
            });
        alert(val);
    //}
}
 </script>

when i run it i get the first alert but then get an error stating the $ is undefined? can some one help please? thanks

Did you include a jQuery script? Here's one from the Google CDN: `` — War10ck, Oct 10 '13 at 12:32

Make sure that your include for jQuery is before this script section, and that you are actually including jQuery.

It sounds like either you are not including jQuery or you're including it after your script. Make sure the jQuery script tag is before your application script.

since scripts load synchronously, the statement about jQuery not being loaded in time seems to be invalid in the provided context – Zathrus Writer Oct 10 '13 at 12:35
Actually it's better to have all of your scripts at the end of your document right before `
`. Also, jQuery will always load in time because scripts load synchronously. The only way there would be a problem is if the script loads asynchronously because of an `async` attribute in the `` tag. No `async`, no problem.

That's very true actually. Bit of a dunce moment on my part haha. – andy Oct 10 '13 at 13:21

Add this code

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js">
