safeclassname

Micro-library for JS that generates a safe CSS classname from a string.

Behaviour

* Special characters are replaced with _x e.g. ! is replaced with _x21.
* If passed undefined or null, safeclassname will return an empty string.

Examples

* safeclassname('Some sentence') - returns "Some-sentence"
* safeclassname('super!') - returns "super_x21"
* safeclassname(undefined) - returns ""
* safeclassname(null) - returns ""
