|
|
|
|
a CSS selector parser
|
|
|
|
## Example
|
|
|
|
```js
|
|
require('css-what')('foo[bar]:baz')
|
|
|
|
~> [ [ { type: 'tag', name: 'foo' },
|
|
{ type: 'attribute',
|
|
name: 'bar',
|
|
action: 'exists',
|
|

## API
|
|
|
|
__`CSSwhat(selector, options)` - Parses `str`, with the passed `options`.__
|
|
|
|
The function returns a two-dimensional array. The first array represents selectors separated by commas (eg. `sub1, sub2`), the second contains the relevant tokens for that selector. Possible token types are:
|
|
|
|
name | attributes | example | output

|
`tag`| `name` | `div` | `{ type: 'tag', name: 'div' }`
|
|
`universal`| - | `*` | `{ type: 'universal' }`
|
|
`pseudo`| `name`, `data`|`:name(data)`| `{ type: 'pseudo', name: 'name', data: 'data' }`
|
|
`pseudo`| `name`, `data`|`:name`| `{ type: 'pseudo', name: 'name', data: null }`
|
|
`pseudo-element`| `name` |`::name`| `{ type: 'pseudo-element', name: 'name' }`
|
|
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr]`|`{ type: 'attribute', name: 'attr', action: 'exists', value: '', ignoreCase: false }`
|
|
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr=val]`|`{ type: 'attribute', name: 'attr', action: 'equals', value: 'val', ignoreCase: false }`
|
|
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr^=val]`|`{ type: 'attribute', name: 'attr', action: 'start', value: 'val', ignoreCase: false }`
|
|
`attribute`|`name`, `action`, `value`, `ignoreCase`|`[attr$=val]`|`{ type: 'attribute', name: 'attr', action: 'end', value: 'val', ignoreCase: false }`
|
