dataset

dataset

Shim for DOM dataset

Installation

$ npm install dataset

API

To set data-xxx attribute on node to 5:

dataset(node, 'xxx', 5);

To retrieve data-xxx attribute value:

dataset(node, 'xxx');

To remove data-xxx attribute:

dataset(node).del('xxx');

You can chain your sets:

dataset(node)
	.set('xxx', 5)
	.set('foo', 'bongo');

Caveats

  • You might not need it: dataset is supported by all modern browsers
  • Do not use on SVG/MathML elements: most browsers only support dataset property on HTML elements and - for performance reasons - this shim only checks for dataset support once per load using document.head element to verify the support.
