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

[tubakoseoglu]

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.

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.

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.

Thank you.

I thought this way but cannot find anything how can I get this list in JS.

To read the entries you can use the method getItemAt.

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