Can we clear the selection in JavaScript?

[Gougoul]

I haven t found a way to do it programmatically...

Clear input clears the text but that’s it...

I also found that the clearChoices() method does not reset to the initial state, i.e.: the placeholder is missing.

It's a hack, but this is how I did it for now:

    CHOICES_INSTANCE.clearChoices();
    document.querySelector("div.choices__item").innerHTML="Make your choice";
    document.querySelector("div.choices__item").setAttribute("data-value","Make your choice");
    document.querySelector("div.choices__item").setAttribute("data-id","1");
    document.querySelector("div.choices__item").classList.add("choices__placeholder");
    CHOICES_INSTANCE.setChoices({value: 'whatever', label: 'whatever'}, 'value', 'label', false);

If you have multiple instances, make sure that you are more specific with the document.querySelector().

Wait...

Are you saying that clearing selected values to have default state of the choices requires above hack?

This or destroy + clear selected + init of the whole thing?

To reset values?

I wish i knew that couple weeks ago...

For anyone else who stumbles across this thread, you can use the removeActiveItems method.

Thanks, it works like a charm!

Hi, I was having problems clearing the select after a submit so, given that I haven't found a concise example on how to use removeActiveItems I ended up using the code on this link:

https://jsfiddle.net/pvvnxdementor5/og7yhu4t/42/

I added the clear button, give it an id (a class would work also) and on the function that handles the post success aftermath, I simulate a click to the clear button

document.getElementById("clearBtn").click()

So maybe this works for somebody else. I'm not an expert on JS and this library works awesome but I do find it really hard to find instructions on how to call methods after the select choice is created

Hello.

Taking advantage of this issue. Is there any way to unselect some items by passing an array of ids as a argument?

Hello.
I have a close problem with choices.js and form.reset.
I change values in a mysql database and i am using ajax for it. Everything is fine an works. But some values have to be values from a list, so a select is the correct way for me, but the select list ist very long, so i need a "search" in this too. I tried choices.js and it work very fine in a modal (select2 or selcetize works in a modal not).
But my problem is, if i press the button "add" or "change" to add or edit something, then i have to reset my form with form.reset, cause if not, then the values from before are still in the field. I know, it sounds complicated but i hope somebody can understand me. But if i reset my form, then the values of my choices select are empty and i can choose nothing. Can somebody help me how i can fix that? And by the "change value" i need the value, who is saved in database.
Maybe somebody have a little jsfiddle or something where i see how to use "setchoices" and that it not crash when i reset with form.reset().
Btw, i know my english is not the best, sorry if somebody can't understand me.

My problem with this answer is that it also removes the placeholder of a select-one:

<select>
  <option value="">This is a placeholder</option>
  <option>...</option>
  <option>...</option>
  <option>...</option>
</select>

I have the same issue when trying to use single select.
Is it is what I'm doing wrong or it's a plugin mistake?

The way I have found how to solve a problem:

1. Call destroy method
2. Replace Select tag with the default one.
3. Call custom init function (not build-in Choices Plugin init function) with all parameters, events and etc again.

Below the code what I used and have found an issue.

HTML Code:

<select name="item_id">
  <option value="" disabled selected>Placeholder</option>
  <option value="1">Item #1</option>
  <option value="2">Item #2</option>
  <option value="3">Item #3</option>
</select>

JS Code for testing:

const choice = new Choices(element, {
  position: 'below',
  itemSelectText: '',
  shouldSort: false,
  searchPlaceholderValue: $(element).find('option[value=""]').text(),
  fuseOptions: {
    threshold: 0.0,
  },
});

element.addEventListener(
    'choice',
    function(event) {
      // How to reset selected options here correctly to default?
    },
    false,
  );
};

Oh, I have found a solution. If you use plugin methods in events then you need to put your plugin methods in setTimeout(). A great reminder to reread info about event loops!

clearChoices still doesn't work.

<button name="button" type="button" class="btn btn-secondary" data-action="click->check#clean"><i class="bi bi-eraser"></i> </button>

function clean(event) {
  let el = event.target.closest('form').querySelector('.form-select')
  let finded_choice_select = new Choices(el)
  finded_choice_select.clearChoices()
}

Any advance in this issue for select-one type? I want to change the options programatically. I'm using clearChoices() to remove old choices and setChoices() to add new ones but old selected value remains.

Nevermind, I just solved it:

1. clearChoices() to remove old choices
2. setChoices( newChoices ) to add new choices
3. setChoiceByValue( newChoices[0] ) to replace selected old choices with first new choice

[codernik]

I see that, there is one parameter which is accepted by the function removeActiveItems(excludedId: number).
So if you are using placeholder, passing 0 or 1 as per the index should work.

<select>
  <option value="">This is a placeholder</option>
  <option>...</option>
  <option>...</option>
  <option>...</option>
</select>

Call the destroy() method first and then init()

const example = new Choices(element);
example.destroy();
example.init();

It's work for me. Thanks.
