Uncaught TypeError: $(...)[J72] is not a function - unable to get editor to work

I'm trying to get the editor to work on a simple example table but keep getting the following error when trying to add a new item. Debugger doesn't give me any errors. It says this:

datatables.min.js:200 Uncaught TypeError: $(...)[J72] is not a function

Table ID    Problem description
#example    Your table is not inside a `container` or `container-fluid` element. This can cause the table to be misaligned due to the use of negative margins on the column layout used by DataTables for Bootstrap. Typically you should include a container element near the top level of your HTML.
-   Using FixedHeader without setting a `meta` tag to "user-scalable=no" will mean that FixedHeader does not work on Android devices as `position:fixed` is disabled in the browser under those conditions. Either add a suitable meta tag, or be aware that FixedHeader will not operate for Android users.

    Interesting. Are you able to give me a link to your page so I can debug it please?

    The error message suggests that something is going wrong when an error message is being displayed to the end user. But I don't see anything in the code that would cause that to be displayed. If you can give me a link to the page, hopefully I'll be able to track it down.

    Allan, I sent you a message with a link to the page.

    var dateKey = +new Date(); What does the + sign do?

  • chaseoeschaseoes Posts: 4Questions: 1Answers: 0

    Not sure, that was file was copied and pasted directly from the Editor example code here: https://editor.datatables.net/examples/advanced/localstorage.html

  • allanallan Posts: 47,496Questions: 1Answers: 6,751 Site admin

    Its a short cut - it basically just converts the Date object into a number due to Javascript's loose typing:

    +new Date();


    new Date().getTime()`

    are the same thing.

    @chaseoes: I'll check my PM's in a moment. Just going through my forum "rounds".


  • allanallan Posts: 47,496Questions: 1Answers: 6,751 Site admin

    Got it - thanks for the PM!

    The issue is that jQuery Slim is being used. The line that is failing (obfuscated) is:

    el = $(el).stop();

    jQuery slim doesn't include its animation support and to be honest, I hadn't realised that! At the moment the workaround is to use jQuery normal, but I'll add support for jQuery slim into the next version of Editor.

    Thank you! I can't get inline editing to work now, I added this code but it doesn't seem to make a difference:

    $('#example').on( 'click', 'tbody td', function () {
        editor.inline( this );
    } );

    Can you link to the page showing the issue so I can debug it please?
