Custom menu with an AJAX call

Development

You’re right :slight_smile:

Here’s the code I have a mistake with.

export default createWidget('discourse-custom-header', {
    tagName: 'div',

    html() {
        return $.when($.ajax({
            url: 'http://www.example.com/menu',
            async: false
        })).then(result => {
            return [
                h('div', [
                    new RawHtml({ html: `${result}` })
                ])
            ];
        });
    }
});

I get this warning

[Deprecation] Synchronous XMLHttpRequest on the main thread is deprecated because of its detrimental effects to the end user’s experience. For more help, check https://xhr.spec.whatwg.org/.

and this error

Error: Unexpected virtual child passed to h().
Expected a VNode / Vthunk / VWidget / string but:
got:
{}.
The parent vnode is:
{
    "tagName": "DIV",
    "properties": {
        "attributes": {},
        "className": "custom-menu"
    }
}
