html-class-data.js
encode / decode data stored in an HTML class attribute (like Angular)
What is this?
It may be convenient to encode values within an HTML class attribute, just like the CSS syntax for Angular directives. We provide a helper function to decode such attributes.
API
We export an Object with the following function(s)...
decode()
- @param {String} class contents of an HTML 'class' attribute
- @returns {Object} key-value pairs of properties encoded in the string
The returned Object will always have a "class" property, with a String value containing any non-Setting content (i.e. actual CSS classes). We consider everything after the last semi-colon to be CSS classes.
If there is no semi-colon at all, then we treat the whole string as a normal CSS
class. For example, cat dog becomes:
{
"class": "cat dog"
}Inspired by HTML attributes, we consider any Setting that does not have an
explicit value to be a Boolean Setting, with a default true value.
For example, cat; dog becomes:
{
"class": "dog",
"cat": true
}Use semi-colons to delimit Settings, and use colons to delimit Setting key-value pairs. We ignore spaces when parsing Settings.
For example, cats: rule; dogs: drool; becomes:
{
"class": "",
"cats": "rule",
"dogs": "drool"
}For multi-word Setting names, follow CSS conventions by using lower-case kebab-style. We convert this to camelCase automatically to follow JavaScript conventions.
For example, multi-word: value; becomes:
{
"class": "",
"multiWord": "value"
}
