How do you access the text value of the Dropdown UI?

Question

Whenever the value is changed, I need to get the text as string and print it out. I have tried using the code below but it always returns null. Thank you in advance.

 var LocationPicker : GameObject;
 var LocPickerString : String;

 function Start () {

 LocPickerString = LocationPicker.GetComponent.<UI.Dropdown>().OptionData().text;

 Debug.Log(LocPickerString);}

You can simply do this:

 Debug.Log(Dropdown.options[Dropdown.value].text);

I couldn't get the above answers to work, so here is another (simpler) option for future readers:

     //find your dropdown object
         public Transform dropdownMenu;
 
     //get the selected index
         int menuIndex = dropdownMenu.GetComponent<Dropdown> ().value;
 
     //get all options available within this dropdown menu
         List<Dropdown.OptionData> menuOptions = dropdownMenu.GetComponent<Dropdown> ().options;
 
     //get the string value of the selected index
         string value = menuOptions [menuIndex].text;

Unless for temporary use, it is better to work with the index. Problem will arise when globalizing your text!

Turns out that the selected value is always reflected real time in the Text component of a child of the Dropdown, which is the Label. So here is what I had done:

 var LocationPickerLabel : GameObject;
 private var SelectedLocation : Text;
 var LocName : String;

 function Start () {

 SelectedLocation = LocationPickerLabel.GetComponent(UI.Text);

 LocName = SelectedLocation.text;}

A little out of topic, but I can also set the value from the start and therefore typing in an instruction before the drop down is pressed by typing SelectedLocation.text = "Any instruction that I need ..." in the start function.

Doesn't work when you manually override the label. In my case it says "Please select your instrument", but Piano is selected by default.

It's been a while since I worked with this issue. Your case certainly needs better solution than this. Perhaps the other answers below could help you get some ideas on how to proceed with your case?

Try: LocPickerString = LocationPicker.GetComponent.<UI.Dropdown>().itemText.text

Thanks for the quick reply. In case anyone is wondering, this will return the default value of the dropdown option, which is "Option A".

The following will give you the text from the selected dropdown item:

 Debug.Log(EventSystem.current.currentSelectedGameObject.name);
