JavaScript => public static function GetNameOfFocusedControl(): string;
C# => public static string GetNameOfFocusedControl();

Description 描述

Get the name of named control that has focus.

获取有焦点被命名控件的名字

Control names are set up by using SetNextControlName. When a named control has focus, this function will return its name. If no control has focus or the focused control has no name set, an empty string will be returned instead.

控件名字由SetNextControlName设置，当被命名控件有焦点，这个函数将返回他的名字，如果没有控件获得焦点或有焦点控件没有名字将返回空字符串。

JavaScript:

	var login : String = "username";
	var login2 : String = "no action here";
 
	function OnGUI () {
		GUI.SetNextControlName ("user");
		login = GUI.TextField (Rect (10,10,130,20), login);
 
		login2 = GUI.TextField (Rect (10,40,130,20), login2);
		if (Event.current.isKey && Event.current.keyCode == KeyCode.Return &&
			GUI.GetNameOfFocusedControl () == "user") {
			Debug.Log ("Login");
		}
 
		if (GUI.Button (new Rect (150,10,50,20), "Login"))
			Debug.Log ("Login");
	}

C#:

using UnityEngine;
using System.Collections;
 
public class ExampleClass : MonoBehaviour {
    public string login = "username";
    public string login2 = "no action here";
    void OnGUI() {
        GUI.SetNextControlName("user");
        login = GUI.TextField(new Rect(10, 10, 130, 20), login);
        login2 = GUI.TextField(new Rect(10, 40, 130, 20), login2);
        if (Event.current.isKey && Event.current.keyCode == KeyCode.Return && GUI.GetNameOfFocusedControl() == "user")
            Debug.Log("Login");
 
        if (GUI.Button(new Rect(150, 10, 50, 20), "Login"))
            Debug.Log("Login");
 
    }
}
