Function declarations, which declare a variable and assign a function to it, are similar to variable statements, but in addition to hoisting the declaration, they also hoist the assignment – as if the entire statement appeared at the top of the containing function – and thus forward reference is also possible: the location of a function ...
Immediately invoked function expressions may be written in a number of different ways. [3] A common convention is to enclose the function expression – and optionally its invocation operator – with the grouping operator, [4] in parentheses, to tell the parser explicitly to expect an expression.
It introduced the getElementById function as well as an event model and support for XML namespaces and CSS. DOM Level 3, published in April 2004, added support for XPath and keyboard event handling, as well as an interface for serializing documents as XML. HTML5 was published in October 2014. Part of HTML5 had replaced DOM Level 2 HTML module.
Dynamic HTML, or DHTML, is a term which was used by some browser vendors to describe the combination of HTML, style sheets and client-side scripts (JavaScript, VBScript, or any other supported scripts) that enabled the creation of interactive and animated documents.
The call stack shrinks and grows based on the function's needs. When the call stack is empty upon function completion, JavaScript proceeds to the next message in the queue. This is called the event loop, described as "run to completion" because each message is fully processed before the next message is considered.
Example include: file or virtual This is probably the most used SSI directive. It allows the content of one document to be transcluded in another. The included document can itself be another SSI-enabled file. The file or virtual parameters specify the file (HTML page, text file, script, etc.) to be included.
Ext JS is a JavaScript application framework for building interactive cross-platform web applications [2] using techniques such as Ajax, DHTML and DOM scripting. It can be used as a simple component framework (for example, to create dynamic grids on otherwise static pages) but also as a full framework for building single-page applications (SPAs).
Doctype HTML is a declaration that tells the browser what version of HTML the document is written in. Some attribute types function differently when used to modify different element types. For example, the attribute name is used by several element types, but has slightly different functions in each. [1]
