Extensions

Extensions are functions that can hook into well-defined points in the HTML generation process. A client can provide an array of extensions to the marked-it.generate() options object.

All extension functions receive two arguments:

value: the default value that has been generated
data: additional data and functions that may be helpful for generating a replacement value

If the extension function returns any string, including "", then that string will replace the initially-generated value in the end document. If a non-string value is returned then the initially-generated value is preserved.

For an example of an extension that adds elements to generated

elements see ./examples/extension-tableCaptions.js.

HTML Generation extensions

All extensions in this section receive a data object containing:

htmlToDom(string, options)

A function that returns the HTML string for a DOM object. See options.

domToHtml(dom, options)

A function that returns a DOM representation of an HTML string.

options:

xmlMode:
decodeEntities:

domToInnerHtml(string, options)

A function to convert a DOM object to its inner HTML string. It takes the same options as the domToHtml function.

domUtils

An object with functions for manipulating DOM objects. The functions are defined in the various files here.

replaceVariables(string, variableMaps)

A function that can be used to replace all occurrences of {{<variableName>}} in a string with the corresponding variable values. This function comes pre-seeded with all currently-scoped variable values. Optionally, additional maps containing more variable name->value pairs can be provided.
