Modernizr offers tests for more than 250 features, then creates a JavaScript object (named "Modernizr") that contains the results of these tests as boolean properties. It also adds classes to the HTML element based on what features are and are not natively supported.
Form, link and image elements could be referenced with a hierarchical name that began with the root document object. A hierarchical name could make use of either the names or the sequential index of the traversed elements. For example, a form input element could be accessed as either document.myForm.myInput or document.forms[0].elements[0].
The scoped subtree in an element is called a shadow tree. The element the shadow tree is attached to is called a shadow host. [6] A Shadow DOM must always be connected to an existing element, either through attaching it as a literal element or through scripting. In JavaScript, Shadow DOMs are attached to an element using Element.attachShadow(). [7]
A class may be produced by the software, e.g., ns-namespace number for the HTML-element "body", and extiw for an interwiki link in the page body, or taken from the wikitext. Similarly, an ID may be produced by the software, e.g., bodyContent, or taken from the wikitext.
Using this pair of classes, it is possible to make an element collapsed by default only when it is contained within a particular outer element. An element with the mw-collapsible and innercollapse classes is collapsed by default if it is contained within an element with the outercollapse class; otherwise, it is uncollapsed by default. This is ...
The class attribute provides a way of classifying similar elements. Multiple class names can be added by separating them with spaces. [10] [11] Semantically, for example, classes are used in microformats. Additionally authors of style sheets can construct selectors that match elements by class for styling
If your code works with page content and adds event handlers to DOM elements, then, instead of hooking to 'wikipage.content' and looking for elements to attach event listeners to when it is fired, you may attach one event listener to an element outside of the content area or the whole document but filter events by a selector (see jQuery's ...
To import JavaScript classes, the dependency on TObject as the root of all class types needed to be modified. This allows the user to define a class as external, and classes written in JavaScript that match the interface can thus be created and used alongside those written in Pascal. Anonymous classes can also be used as lightweight objects.
