DOM Events
DOM (Document Object Model) Events are a signal that something has occurred, or is occurring, and can be triggered by user interactions or by the browser. Client-side scripting languages like JavaScript, JScript, VBScript, and Java can register various event handlers or listeners on the element nodes inside a DOM tree, such as in HTML, XHTML, XUL, and SVG documents. Examples of DOM Events: * When a user clicks the mouse * When a web page has loaded * When an image has been loaded * When the mouse moves over an element * When an input field is changed * When an HTML form is submitted * When a user presses a key Historically, like DOM, the event models used by various web browsers had some significant differences which caused compatibility problems. To combat this, the event model was standardized by the World Wide Web Consortium (W3C) in DOM Level 2. Events HTML events Common events There is a huge collection of events that can be generated by most element nodes: * ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pointing Device
A pointing device is a human interface device that allows a User (computing)#End-user, user to input Three-dimensional space, spatial (i.e., continuous and multi-dimensional) data to a computer. Graphical user interfaces (GUI) and Computer-aided design, CAD systems allow the user to control and provide data to the computer using physical Mouse gesture, gestures by moving a hand-held Mouse (computing), mouse or similar device across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the Pointer (computing WIMP), pointer (or Cursor (user interface), cursor) and other visual changes. Common gestures are point and click and drag and drop. While the most common pointing device by far is the mouse, many more devices have been developed. However, the term ''mouse'' is commonly used as a metaphor for devices that move a computer cursor. Fitts's law can be used to predict the speed with ...

Tabbing Navigation
The tab key (abbreviation of tabulator key or tabular key) on a alphanumeric keyboard, keyboard is used to advance the cursor to the next tab stop. History The word ''tab'' derives from the word ''tabulate'', which means "to arrange data in a tabular, or table, form". When a person wanted to type a table (of numbers or text) on a typewriter, there was a lot of time-consuming and repetitive use of the space bar and backspace key. To simplify this, a horizontal bar was placed in the mechanism called the tabulator rack. Pressing the tab key would advance the carriage to the next tab stop, tabulator stop. The original tabulator stops were adjustable clips that could be arranged by the user on the tabulator rack. Fredric Hillard filed a patent application for such a mechanism in 1900. The tab mechanism came into its own as a rapid and consistent way of uniformly Indentation (typesetting), indenting the first line of each paragraph. Often a first tab stop at 5 or 6 characters was ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Focus (computing)
In a computing graphical user interface (GUI), a component has focus when it is selected to receive input from the user by an event such as a mouse button click or keypress. Moving the focus away from a specific user interface element is known as a blur event in relation to this element. Typically, the focus is withdrawn from an element by giving another element the focus. This means that focus and blur Event (computing), events are virtually simultaneous in relation to different user interface elements, one that becomes focused and one that is "blurred" (in the computing, not visual, sense). The concept is similar to a Cursor (user interface), cursor in a text-based environment. However, when considering a graphical interface, there is also a mouse pointer involved. Moving the mouse will typically move the mouse pointer without changing the focus. The focus can usually be changed by clicking on a component that can receive focus with the mouse. Many Desktop environment, desktops al ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Text Box
A text box also called an input box, text field or text entry box, is a control element of a graphical user interface, that should enable the user to input text information to be used by a program. Human Interface Guidelines recommend a single-line text box when only one line of input is required, and a multi-line text box only if more than one line of input may be required. Non-editable text boxes can serve the purpose of simply displaying text. A typical text box is a rectangle of any size, possibly with a border that separates the text box from the rest of the interface. Text boxes may contain zero, one, or two scrollbars. Text boxes usually display a text cursor (commonly a blinking vertical line), indicating the current region of text being edited. It is common for the mouse cursor to change its shape when it hovers over a text box. Standard functionality Typical implementations allow a user to do the following. (The keys indicated relate to the text box widgets in M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Form (HTML)
A webform, web form or HTML form on a web page allows a user to enter data that is sent to a Server (computing), server for processing. Forms can resemble form (document), paper or database forms because web users fill out the forms using checkbox, checkboxes, radio buttons, or text fields. For example, forms can be used to enter shipping or credit card data to order a product, or can be used to retrieve search results from a search engine. Description Forms are enclosed in the HTML <form> element. This HTML element specifies the communication endpoint the data entered into the form should be submitted to, and the HTTP request, method of submitting the data, GET or POST. Elements Forms can be made up of standard graphical user interface elements: * <text> — a simple text box that allows input of a single line of text. * <email> - a type of <text> that requires a partially validated email address * <number> - a type of <text> that requir ...

The so-called big five game, "Big Five" game animals of Africa – lion, African leopard, leopard, rhinoceros, African elephant, elep ..., some email clients, standalone download managers like youtube-dl, and other command-line utilities like cURL. The user agent is the client in a client–server system. The HTTP User-Agent header is intended to clearly identify the agent to the server. However, this header can be omitted or spoofed, so some websites use other detection methods. References Clients (computing) {{Web-stub ...
