How to update the knockout.js input field from a content script on Chrome extension?

Question

To update a knockout.js input field from a content script in a Chrome extension, you can use the
value binding to bind the input field to a property on your view model, and then update the property in your content script.
Here's an example code snippet:
In your HTML file, define the input field and bind it to a property on your view model using the
value binding:
andlt;input type="text" data-bind="value: myValue">
In your content script, you can access the input field by its ID and update its value by updating the corresponding property on your view model:
// Get the input field element by ID
var inputElement = document.getElementById("myInput");
// Update the value of the input field
inputElement.value = "New Value";
// Update the corresponding property on your view model
myViewModel.myValue("New Value");
In this example, we get the input field element by its ID using getElementById(), update its value directly using the
value property, and then update the corresponding property on our view model using the property's setter method.
Note that you will need to ensure that your content script has access to the view model and any other necessary dependencies. You can do this by injecting your content script into the page and using the
ko.dataFor() method to access the view model.
