Using keypress event in knockout JS

  • 2 Answer(s)
    • Check that the query is an observable
    • Use   valueUpdate = ‘afterkeydown’
    • Use   event: { ‘keyup’: check }:

       Use the  console.log if possible as opposed to alert, and log the query to check the  value is updating.. For log the event ,See this

    function check(data, event)

       The KO docs, at least as of now, specifically addresses this issue:

    Note 1: textInput vs value binding

       Eventhough the value binding do two-way binding between text boxes and viewmodel properties, Then prefer the textInput whenever sudden live updates is needed.
