typescript event handling with oninput

When working with a slider, I am trying to detect when the user changes the value of the slider in order to display it. I have been following the tutorial at https://www.w3schools.com/howto/howto_js_rangeslider.asp.

However, this code is not compatible with TypeScript. Currently, I am using the following code:

 var slider = (<HTMLInputElement>document.getElementById("myRange")).value;
    var output =  document.getElementById("demo");
    output.innerHTML = slider

In an attempt to capture the event, I tried:

const onChange = output.innerHTML = slider;

But the value is not changing. Do you know how to use the event oninput in TypeScript?

Answer №1

In order to track changes, it is recommended to utilize the oninput method of the slider object as shown below:

slider.oninput = e => {
    output.innerHTML = e.target.value;
};

To see a live example, you can check out the demonstration provided on w3s site here
