Question

I am learning jQuery so please bear with me. I am attempting to populate an HTML unordered list using the following code. The error I am encountering is:
HTMLfile: No such interface. The code breaks on the following jQuery library statement:
fragment.appendchild(script)

Here’s the code (a fragment of a successful jQuery Ajax call).

Json contains ID and Name.

          success: function(data) {
        var $defs = $('<ul id="mylist"></ul>').insertBefore('#lst');
          $.each(data.d, function (index, list) {
            $(this).appendTo($defs).wrap("<li>" + list.Name + "</li>");
          })
        },

Thank you

I can’t be sure, because there is not enough of your script here, but it may be that your this statement isn’t pointing to an HTML element. Console log your this statement to see what it is. I don’t know what data.d is, but jQuery likes to replace this statements when you might not expect it to.

Maybe show more of your code?

Learning to understand what this is in JavaScript can be hard enough for people new to the language, so I generally advise people to learn JavaScript, before learning jQuery. Otherwise I think it will take longer to learn JavaScript, and be harder, more error-filled learning experience.
