Events

Property: Function:
On Value Change A UnityEvent that is invoked when the text content of the Input Field changes. The event can send the current text content as a string type dynamic argument.
End Edit A UnityEvent that is invoked when the user finishes editing the text content either by submitting or by clicking somewhere that removes the focus from the Input Field. The event can send the current text content as a string type dynamic argument.

Details

The Input Field script can be added to any existing Text control object from the menu (Component > UI > Input Field). Having done this, you should also drag the object to the Input Field’s Text property to enable editing.

The Text property of the Text control itself will change as the user types and the value can be retrieved from a script after editing. Note that Rich Text is intentionally not supported for editable Text controls; the field will apply any Rich Text markup instantly when typed but the markup essentially “disappears” and there is no subsequent way to change or remove the styling.

Hints

  • To obtains the text of the Input Field, use the text property on the InputField componentA functional part of a GameObject. A GameObject can contain any number of components. Unity has many built-in components, and you can create your own by writing scripts that inherit from MonoBehaviour. More info
    See in Glossary
    itself, not the text property of the Text component that displays the text. The text property of the Text component may be cropped or may consist of asterisks for passwords.
