How to programatically add options on a select? #586

Open punto- opened 6 years ago

punto- commented 6 years ago

Hi.

How do I programatically add options to a select? I tried using the "add()" function as if it was a "normal" html select widget but it doesn't seem to work. Is there API to do this, or do I have to somehow obtain the underlying html element? (I tried with getControlEl() and it didn't work either).

Thanks

See http://www.alpacajs.org/docs/api/observables.html. Example:

{
    "schema": ...,
    "options": ...,
    "postRender": function(control) {
        control.schema.enum = [ ... ];
        control.refresh();
    }
}

maybe simple dependencies are what you want: http://www.alpacajs.org/docs/api/dependencies.html
