Manually set the selected item

[fiscio]

Hi there,

first of all, thanks to the devs for this great js component, that looks very promising.

I think I got it to work but still there is something, that sorta sounds rather basic, that I didn't get to work so far.

I have in the DOM a basic tom-select element, built the regular way, say:

<select><optgroup><option></option></optgroup></select>

1. The element is among other input fields that belong to a form within a Bootstrap card component.
2. Now I change the value of the tom-select field (by selecting one of the available options).
3. Let's imagine now that I don't like to submit those changes, then I'd now need to "reselect" the previously selected option (meaning "resetting" the form to its previous state). For that, what I do is request the values I want via ajax and set them on the inputs upon ajax success.

But I haven't figured out yet how to do it with the tom-select. The rest of the fields they work just fine.

I received the values via ajax in "room_id" and "room_name" (which are the option "value" and option "text" respectively)

I tried SetValue() and setTextboxValue() but didn't pan out ...

** I'd figure it'd be something similiar to a regular Select input where you only need to set the option's value and that's it.

Thank you in advance. Hope someone understand and can help.

Cheers!

Yeah, based on your description I'd think setValue() would work. Could you set up a jsfilddle to demonstrate your scenario?

Hi,

thanks for your answer. I've tried again with setValue() and I finally got it to work but I had to "force" the value type by using parseInt() , otherwise didn't work.

From the values got via ajax ("location" var), I had to do:

tomsels[tomsel_id].setValue(parseInt(location.room_id));

and now it's working but I wonder why it does not work without using parseInt(). Any ideas?

Cheers!

Hmm, I'm not seeing a difference between setValue(1) and setValue("1"). Could you set up a jsfiddle?

Hi,

sorry for my late reply.

You're absolutely right, my bad!
My mistake was a wrong evaluation on the server side... I revisited my PHP code and it happens I was serving a string via ajax instead of an integer...

I'm sorry I wasted your time.
Thanks again and keep up the good work!

** updated
What I meant is I don't really know exactly what I was doing because you're right and using a string or integer makes no difference at all. Sorry again.
