#Virtual key codes code
An example of a more advanced code snippet is given later.ĭefine a container for the keyboard, which must be an empty DIV or SPAN. Note that this is the most basic callback function. It may be useful if you bind a single callback function to multiple vkeyboards. The second parameter is optional and accepts the id of the container of the vkeyboard that called the callback. The first parameter is mandatory and accepts a string value returned by the vkeyboard script. The callback function must have one or two parameters. Text.value = val.substr( 0, val.length - min) Var min=(val.charCodeAt(val.length - 1) = 10) ? 2 : 1 Let's bind vkeyboard to the // with id="textfield": var text =ĭocument.getElementById( " textfield"), val = text.value Minimal callback function: function keyb_callback(char) Include a reference to the chosen script file in your HTML page: Vatmpad.js ( 4-numpad_atm folder) is a stripped numpad that contains only the Enter and number keys.
Vnumpad.js ( 3-numpad_full folder) is the numpad part of the keyboard. This installation is recommended if you're short on space (UMPC, touchscreen kiosk, etc.) or if you have 4 or more layouts installed.
The cells are arranged in rows, not as a simple drop-down menu like in the previous variant. Vkboards.js ( 2-vkboard_slim folder) is almost the same as previous, but the language menu, which can be accessed by clicking on the red rectangle in the left-bottom corner of the keyboard, has a special configuration. Vkboard.js ( 1-vkboard folder in the archive) is the primary script. Virtual Keyboard is an open-source script distributed under the zlib/libpng license. To be able to fine-tune the script, you must be familiar with W3C DOM Level 1, CSS Level 1 and the DOM/Microsoft Internet Explorer event model. Installation of the Virtual Keyboard requires a casual knowledge of HTML and JavaScript.
Allow text input from computers without keyboards or with sensor screens - hand-held PCs, smartphones, etc.Web-based e-mail - that can be used worldwide.
