Update displayed information according to the dropdown option selected

Currently, I am working on implementing a dropdown feature that allows users to switch between two different views of the same information. I am looking for guidance on how to connect my dropdown selection to control which div is visible to the user, while hiding the other. Here is an overview of what I have done so far:

<select data-bind="options: displays, value: selectedDisplay, optionsText: 'displayOption'"></select>

The available display options are: 'Display 1' and 'Display 2'

I have set up two div elements, one for each display option.

<div id="display1">.....</div>
<div id="display2">.....</div>

Initially, 'display1' will be shown while 'display2' will be hidden. Upon selecting a different display option, the active display will remain visible and the inactive one will be hidden.

Below is a snippet of my view model code:

self.displays = ko.observableArray();
self.selectedView = ko.observable();

var sampleData = {

        displays: [
            {
                display1: 'Display 1'
            },
            {
                display2: 'Display 2'
            }
        ]
    };

Answer №1

To implement a visible binding on each div and have it check the value of selectedDisplay.

let viewModel = {
  selectedDisplay: ko.observable(),
  displays: [
    1, 2
  ]
};

ko.applyBindings(viewModel);
<script src="https://cdnjs.cloudflare.com/ajax/libs/knockout/3.2.0/knockout-min.js"></script>
<select data-bind="options: displays, value: selectedDisplay"></select>
<div data-bind="visible:selectedDisplay() == 1">This is Div 1</div>
<div data-bind="visible:selectedDisplay() == 2">You see Div 2</div>
