Utilities to combining & compose Knockout observables
Utilities to combine & compose Knockout observables
kc.fieldsexplodes an observable of an object into observables for each field.
kc.objectcombines an object of observables into an observable of an object.
kc.everycombines a list of observables into one observable that is true whenever they all are.
kc.anycombines a list of observables into one observable that is true whenever any is.
kc.togglecreates a callback to toggle a
Booleanobservable, useful for
kc.toggleFieldtoggles a field of the view model by name.
kc.monotonicObjectbuilds an object based on values it sees in an observable array (this one is a bit fancier).
kc.deepUnwraprecursively traverses a value and unwraps all the observables it sees. Especially handy for logging.
kc.wrapwraps a value in an observable if it is not already.
kc.monitorlogs every change to an observable to the console (throttled as this can be crazy).
kc.sumsums the values in an observable array.
See the code itself for more details; each function is really quite small. To be expanded as I scrape these out of my various codebases. Pull request very welcome!
