dom-visitor


Visitor designed for DOM crawling and node modification.
It can be used for VDOM traversal with "breadth" and custom "childrenProp".

If you'd like a sensible way of collecting information about nodes,
then I'd recommend using the dom-reducer:

- https://www.npmjs.com/package/dom-reducer
- https://github.com/stormcrows/dom-reducer

DOMVisitor takes 2 arguments:

- startingNode
ex.: document.body,

- fn, a function called on every node,
ex.: node => (node["onclick"] ? delete node["onclick"] : void 0)

- options:
- method: "preOrder" | "breadth"
* defaults to "preOrder",

- childrenProp: string
* defaults to "childNodes"

DOMVisitor supports Browser, Node.js & AMD.

USAGE

Refer to index.spec.js for "breadth-first" traversal.

In browser: inject DOMVisitor code unto a website through devtools or script tag,
then:

``javascript
const removeAttribute = (attr, node) =>
DOMVisitor(
node,
node => (node[attr] ? delete node[attr] : void 0)
);

removeAttribute("onclick", document.body);
``

Happy DOM crawling!
