The DOM clobbering vulnerability arises from a naming collision between the JavaScript execution context and HTML elements in the Document Object Model (DOM). When an undefined JavaScript variable is declared in the same context as an HTML element with the same name or id parameter, the browser will assign the HTML element to the undefined ...
In HTML DOM (Document Object Model), every element is a node: [4] A document is a document node. All HTML elements are element nodes. All HTML attributes are attribute nodes. Text inserted into HTML elements are text nodes. Comments are comment nodes.
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). [vague] The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML.
Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments , however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
Link to an anchor in the same article using just the anchor name, e.g. [[#Anchor name]]. (In the Visual Editor, type #Anchor name into the link field.) From a different article, link to an anchor by specifying the article name, followed by a #, then the anchor name. e.g. [[Article name#Anchor name]]. The # will be visible in the link text.
The template can be used to create multiple anchors with a single call. For example, {{anchor|Foo|Bar|baz}} will create three anchors that can then be linked to with [[#Foo]], [[#Bar]] and [[#baz]]. Here is a more literal example: Say you wrote an article about a recently discovered Indo-European language called "Yish Yash".
For example, if rolling the mouse over a 'Buy now' link is meant to make the price, elsewhere on the page, become emphasized, JavaScript code can do this, but JavaScript needs to identify the price element, wherever it is in the markup.
Sorting a mixed set of objects: algorithms require that a list of objects be sorted into some canonical order. Deciding if one element comes before another element requires knowledge of both types and possibly some subset of the fields. Adaptive collision algorithms usually require that collisions between different objects be handled in ...
