How to add item to drop-down list using javascript?

I added button to my pdf and when I clicked to button, it added a textarea dynamically.

So I want to keep these names on drop-down list but I cannot add item dynamically to drop-down in javascript.

I wrote like this;

this.getField("list").setItems(["CustomItem" + count]);

but this code added only one item.

Here's an article on how to add and remove items from a list and/or dropdown. And there is a sample file.

You must use a list. Read the items of the dropdown, create a list of this items, and add the new entry. Then use the method setItems with this list.

You can also use the method insertItemAt.

To read the entries you can use the method getItemAt.

Try this:

this.getField("list").setItems(["CustomItem1" + count, "CustomItem2" + count, "CustomItem3" + count ]);

Thank you for answer.

But I added dynamically. New control is adding when I click to a button.

So I must add a new item to old items.

For example first click I want to add new item control1,

second click, add new item control2.
