underscore :: String

underscore() -> string

 

Converts a camelized string into a series of words separated by an underscore ("_").

 

Example

 

'borderBottomWidth'.underscore();

// -> 'border_bottom_width'

 

Note

 

Used in conjunction with dasherize(), underscore() converts a DOM style into its CSS equivalent.

 

'borderBottomWidth'.underscore().dasherize();

// -> 'border-bottom-width'
