How to fire the change event for an input field?

+1
−1

I have added some input to an input field element this way:

const inputFiled = document.querySelector("#example");
inputField.value = "X";

I want to fire a change event for that field right after the input was added.

This is something I want to try after noticing that the input isn't recognized (the form won't be submitted) if added in the above way; rather, it is recognized only by typing/pasting.

How to do that?

Ref. to "the input isn't recognized (the form won't be submitted)" - this sounds strange. When a form is submitted, all its values (except the disabled controls one I guess) should be posted. Normally, there should be no need for explicit event dispatching, unless there is a particular way to implement the submit.

Can you please provide the whole context? That is the relevant form part and associated JS code.

Alexei‭ The change event is not always dispatched when an input field's value it via code, so this is a valid question IMO.

Alexei‭ thanks, I don't know why but regarding the particular form I worked with, I did have to explicitly dispatch the change event for the details (inserted with value) to be recognized/effective and Moshi's way worked for me to do that.

Moshi‭ Yes, you are right. However, since the post does not contain the whole relevant code, I was wondering about the actual issue. I feel that this might be an XY problem, but it is impossible to tell without more code.
