HTML Components

HTML Components (HTCs) are a legacy technology[1] used to implement components in script as Dynamic HTML (DHTML) "behaviors"[2] in the Microsoft Internet Explorer web browser. Such files typically use an .htc extension and the "text/x-component" MIME type.[3]

Not to be confused with Web Components.

An HTC is typically an HTML file (with JScript / VBScript) and a set of elements that define the component. This helps to organize behavior encapsulated in script modules that can be attached to parts of a Webpage DOM.

Example

 
<body>
<ul>
  <li style="behavior:url(hilite.htc)">Example</li>
</ul>
</body>

In this example, the li element is given the behavior defined by "hilite.htc" (a file that contains JScript code defining highlight/lowlight actions on mouse over). The same hilite.htc can then be given to any element in the HTML page - thus encapsulating the behavior defined by this file.

gollark: This could equally be done as a third party library.
gollark: But seriously, I think a single unified crypto API with convenient interfaces could be really valuable.
gollark: Possibly?
gollark: The API should probably be designed so that it provides individual cryptographic primitives for more advanced use but has simpler functions with sensible defaults for the really common things.
