How to enable/disable an input field using knockout.js?

To enable/disable an input field using Knockout.js, you can use the attr binding to dynamically set the disabled attribute based on a boolean observable in your view model.

Here is an example of how you can achieve this:

<input type="text" data-bind="value: inputValue, attr: { disabled: isDisabled }">

<script>
  var viewModel = {
    inputValue: ko.observable(''),
    isDisabled: ko.observable(false)
  };

  ko.applyBindings(viewModel);
</script>

In this example, the inputValue observable represents the value of the input field, and the isDisabled observable determines whether the input field should be disabled or enabled. You can update the value of isDisabled to true or false in your view model based on certain conditions to enable or disable the input field accordingly.
