![]() The input(e) function enters the number into the text box by using the parameter e. Ĭreate the input(e) and del() JavaScript functions on the page. Additionally, set the onclick event of the Backspace button to del() function. Set the onclick events of the ten number buttons to input() function, and then set the parameter of the input() function to this. Ten of these buttons stand for number 0 to number 9 and the last button stands for the Backspace button. To build a demo page, follow these steps:Īdd an HTML div to a blank page and insert several input buttons into the div. HTML code for page layout and some input controls When you open the Default.htm page by using Microsoft Visual Studio, you can find the following two main parts: This sample contains an HTML page without any behind code. However, to substitute for the real keyboard completely by using a virtual keyboard, you need more advanced logic to implement features for some special keys (for example, the Caps Lock and the Shiftkeys). When users click a certain button, the JavaScript function that handles the onclick event will input an appropriated character to a text box. To create a virtual keyboard, you need to add several buttons to a page. ![]() Sometimes when users try to enter their passwords to access to a website, they may want to use a virtual keyboard instead of a real keyboard to protect the passwords from some kind of back-door software (for example, a Key-logger). You can get the sample packages from the following download icons.ĭownload the package now. This code sample demonstrates a step-by-step guide that illustrates how to build a virtual keyboard in your HTML page. To display the keyboard with a black semi-transparent background instead of the classic opaque, call TouchScreenKeyboard.Open() as follows: TouchScreenKeyboard.Open("", TouchScreenKeyboardType.This article describes an All-In-One framework sample that is available for download. To manually open keyboard with secure text input enabled, use the following code: TouchScreenKeyboard.Open("", TouchScreenKeyboardType.Default, false, false, true) This is useful when users are required to enter sensitive information (such as passwords). It is possible to configure the keyboard to hide symbols when typing. TouchScreenKeyboard.area returns real position and size of the keyboard. TouchScreenKeyboard.visible returns true. TouchScreenKeyboard.area returns (0, 0, 0, 0). TouchScreenKeyboard.visible returns false. The sequence of keyboard events is as follows: ![]() You should not query this value immediately after TouchScreenKeyboard.Open(). Note that TouchScreenKeyboard.area will return a Rect with position and size set to 0 until the keyboard is fully visible on the screen. You must have a keyboard instance to use this property. Returns true if the keyboard is activated. Returns the position and dimensions of the keyboard. Returns true if the keyboard is fully visible on the screen and can be used to enter characters. There are three keyboard properties in TouchScreenKeyboard that determine keyboard visibility status and size on the screen. TouchScreenKeyboard.hideInput is a global variable and will affect all keyboards. In such cases, the edit box will always appear. For example, it will not work for phone keypads and multi-line text input. Note that this works only for certain keyboard types and input modes. However, you can disable text preview by setting TouchScreenKeyboard.hideInput to true. This works as preview of the text that user is typing, so the text is always visible for the user.

Can be switched to keyboard with numbers and punctuation. Can be switched to keyboard with letters. TouchScreenKeyboardType.NumbersAndPunctuation The Keyboard supports the following options:- Property: Please see the TouchScreenKeyboard scripting reference for the parameters that this function takes. Use the TouchScreenKeyboard.Open() function to open the keyboard. Currently, GUI.TextField, GUI.TextArea and GUI.PasswordField will display the keyboard see the GUI class documentation for further details. The keyboard will appear automatically when a user taps on editable GUI elements. In most cases, Unity will handle keyboard input automatically for GUI elements but it is also easy to show the keyboard on demand from a script.
