How to cycle through Dropbox items using a button

[defaultfdvs5sd4rd68]

Hello,

I'm am still very new to coding in general, so the following issue is pretty much due to inexperience and lack of coding knowledge. What I am trying to do is cycle through the items inside of a dropdown box using a button. The plan was to have 2 buttons, one for cycling up through the items and one to cycle down, the dropbox would consist of numbers and I would simply click one of the 2 buttons "up" or "down" inorder to get the corresponding number in the list. Would this be possible through javascript? If so, how would I go about doing so?

I've been soaking up all kinds of coding information, however I haven't figured out the code value for the items inside of the Dropbox inorder to tell the buttons to cycle through the list/values

Hi,

that's quite easy to do. Given your drop down is named DDL it ca be don this way:

// Select lower drop down item
var d = this.getField("DDL"),
    i = d.currentValueIndices;

if (i > 0) {
    d.currentValueIndices = i - 1;
}

// Select upper drop down item
var d = this.getField("DDL"),
    i = d.currentValueIndices,
    n = d.numItems;

if (i < n-1) {
    d.currentValueIndices = i + 1;
}
