Get text from Input field in Unity3D with C#

问题

I'm trying to get a text inside an inputField in Unity3D with C#.

I've placed an inputField in my editor, renamed and tagged in: Username_field.

My question is: How i can get the text inside the InputField Username_field in a C# script?

回答1:

Attach below monobehaviour script to your InputField gameObject:

public class test : MonoBehaviour {
    void Start ()
    {
        var input = gameObject.GetComponent<InputField>();
        var se= new InputField.SubmitEvent();
        se.AddListener(SubmitName);
        input.onEndEdit = se;

        //or simply use the line below, 
        //input.onEndEdit.AddListener(SubmitName);  // This also works
    }

    private void SubmitName(string arg0)
    {
        Debug.Log(arg0);
    }
}

You can use the "On Value Change" or "End Edit" event of the InputField.

The Unity3D documentation provides more detail on how to use a UnityEvent: http://docs.unity3d.com/Manual/UnityEvents.html

Alternatively, you should also be able to access the Text using the Text property of the Text control that your InputField is attached to.

using UnityEngine.UI;
public InputField betInput;
void Start () {
    betInput.onEndEdit.AddListener(delegate { inputBetValue(betInput); });
}
public void inputBetValue(InputField userInput)
{
    betValue = int.Parse(userInput.text);
    Debug.Log(userInput.text);
}
