Using Chained Jquery plugin

I am trying to use the remote Chained plugin in CakePhp (http://www.appelsiini.net/projects/chained) I used Jquery to test an alert and that works but just the chained plugin is not working. I am trying to follow the example on their website using their code. If you want to view my page go to http://team.southpacificavionics.com/customers/test login: guest password: password

Solution

  • This has nothing to do with CakePHP really - it's a client-side javascript library.

    But you have two problems, first: 

    (function() { 
    $("#series").chainedTo("#mark");
});

    Is not actually "running", you just defined an anonymous function that would run, if called. It should just be moved, probably, to where you're alert resides:

    <script type="text/javascript">
    $(document).ready(function () {
        $("#series").chainedTo("#mark");
    });
</script>

    Now it'll run, but if you checked the browser Console, it'll be erroring out, something like:

    Uncaught TypeError: $(...).chainedTo is not a function

    It looks like the library isn't running correctly.

    I'm not sure where you got the source code for the jquery chained library, but it's not the current version in the page you link's github grab it from:

    https://github.com/tuupola/jquery_chained/

    A direct minimized version is listed here:
