I am trying to see if a checkbox has been checked and nothing I've tried has worked.

$('#gpgu0').attr('checked') and .prop('checked') both return undefined
$('#gpgu0').is(':checked') always returns false

I am seeing the same results in IE9 and Firefox 18.

Am I missing something?

Is there a way to get all of the values for a particular column in a table, preferably separated by commas but any way at all will do.

I'm trying to use the autocomplete widget to and to populate it I am using a servlet which is returning a JSON array.  Bear with me, I'm not sure how much you need to see so I'm going to include a lot.

Here is how I am constructing the autocomplete right now.  It's not complete yet because I don't really know how to finish:

                $('#usernamesearch').autocomplete({
                    minLength: 2,
                    source: function(request, response) {
                        $.ajax({
                            url: "./UserServlet?action=search",
                            dataType: "json",
                            data: request,
                            success: ""
                        });
                    }
                });

Clearly I need to work on success, that's where my hold up is right now.  Here is the servlet code that builds the JSON array.  The data is coming out of a database using jdbc:

            ResultSet result = stmt.executeQuery();
            JSONArray array = new JSONArray();
            while (result.next()) {
                JSONObject obj = new JSONObject();
                obj.put("fullname", result.getString("fullname"));
                array.add(obj);
            }
            result.close();
            stmt.close();
            log.info(array.toJSONString());
            out.print(array.toJSONString());
            out.flush();

My output from this block of code shows this:
[{"fullname":"andrea danziger"},{"fullname":"Stacey Moda"},{"fullname":"Debbie Jordan"},{"fullname":"Greg Jordan"},{"fullname":"Janet Randall"},{"fullname":"Arjun Ghosh-Dastidar"},{"fullname":"Brian Adamson"}]

This looks like a good JSON array to me, although I'll be the first to admit that I'm not an expert. 
So, what's the next step?  The data is returning, I can see that clearly enough, but how do I parse it and return it to the autocomplete?

I am happy to return the JSON array however it needs to be constructed.  I can also modify the options for the autocomplete.

Thanks in advance.

I'd like to change the mouse cursor to a pointer for the rows in a particular table but I'm not having any luck getting it to work.  Here are some of the things I have tried, but the cursor resolutely refuses to change for me:

                $("#firmtable tr").hover(function() {
                    $(this).css("cursor","pointer");
                }, function() {
                    $(this).css("cursor","default");
                });

$("#firmtable tr").css("cursor","pointer");

Nothing I have tried has made any change at all.

Thanks

I'm hoping someone can help me with a problem I am having.  I am populating a tablesorter using ajax and the number of rows is quickly getting out of hand so I'd like to implement the tablsorterPager.  This works fine when the table rows are included in the jsp page, but when I try to populate dynamically I am still getting all of the rows at once.

Here is the html that builds the two:

            <div id="pager" class="pager">
        <select class="pagesize">
            <option selected="selected"  value="10">10</option>
            <option value="20">20</option>
            <option value="30">30</option>
            <option  value="40">40</option>
        </select>
            </div>
            <table id="usertable" class="tablesorter" border="0" cellpadding="0" cellspacing="1">
                <thead>
                    <tr>
                        <th>First Name</th>
                        <th>Last Name</th>
                        <th>Email</th>
                        <th>Firm Name</th>
                    </tr>
                </thead>
                <tbody>
                   
                </tbody>
            </table>

And here is the javascript that populates the table:

            $(document).ready(function(){
                $("#usertable").tablesorter().tablesorterPager({container: $("#pager")});
            });
            function fillTable() {
                $.ajax({
                    url: "./UserServlet",
                    cache: false,
                    dataType: "json",
                    success: function(data) {
                        $('#usertable tbody').empty();
                        $.each(data, function(k,v) {
                            var firstname = (v.firstname) ? v.firstname : 'FirstName';
                            var lastname = (v.lastname) ? v.lastname : 'LastName';
                            var email = (v.email) ? v.email : 'EMail';
                            var firm = (v.firmname) ? v.firmname : 'Firm';
                            $('#usertable tbody').prepend(
                            '<tr>' +
                                '<td>' + firstname + '</td>'+
                                '<td>' + lastname + '</td>'+
                                '<td>' + email + '</td>'+
                                '<td>' + firm + '</td>'+
                                '</tr>'
                        );
                        });
                        $("#usertable").tablesorter().tablesorterPager({container: $("#pager")});
                    }
                });


I've also had a problem getting the table to be populated in the ready function.  If I put this it does nothing:

            $(document).ready(function(){
                $("#usertable").tablesorter().tablesorterPager({container: $("#pager")});
                fillTable();
            });

But this works:

            $(document).ready(function(){
                fillTable();
                $("#usertable").tablesorter().tablesorterPager({container: $("#pager")});
            });

Any ideas on either of these issues?

Thanks.

Here is the code I am running:

    function isTurbo() {
        $.post("SubscriberMaintServlet?action=isturbo&firm_id="+<%=firmId%> + "&date=" + (new Date()).getTime(),function(data){
            alert(data);
            if(data == "N") {
                alert("Not Turbo");
            }
            else {
                alert("Turbo");
            }
        });
    }

The url is a very straightforward servlet that queries a database and returns either Y or N.  That part is working fine.  The first alert shows Y or N just as it is supposed to.  However, the second alert is always showing Turbo, as though the if statement is not able to compare properly. 
This is probably javascript rather than specific to jQuery, but can anyone see where I'm going wrong?

Thanks

I've been looking for some example code online but nothing I've found works.

I have a multi-select box on my screen.  What is the best way to get an Array of all of the selected options in it?

Thanks
