How to get new value of 'input' when not using JSX/compiler? about apprun HOT 7 CLOSED

Maybe I have to use a plain JavaScript myInput.addEventListener('input', ...), but I'm not sure what's the right time/place to do that. I must of course be sure that myInput is referring to the right input element when the event happens.

from apprun.

I found a solution, and it did not make use of addEventListener. For each input element, I assigned a unique id, an id that also told where in my state/model the new value should go. In the oninput="app.run(...)" of the input element I included the id as a parameter, and in the update handler for that event I could do a document.getElementById(id).value to get the new value. Then I just had to decode the id to find where to put the value.

The way I usually do is to use the event keyword:

oninput="app.run('input_evt', event)"

You can get the value out of the event target:

update = {
  'input_evt': (state, e) => state = e.target.value
}

from apprun.

Thanks. According to MDN: window.event is a proprietary Microsoft Internet Explorer property.
However, it seems to be widely supported.

You can do this too:

oninput="app.run('input_evt', this)"
update = {
  'input_evt': (state, el) => state = el.value
}

from apprun.

Of course. Why didn't I think of that? ;-)
