How do I get an input value in Blazor WebAssembly?

The input element value is updated by the @bind event in Blazor. To get the current input value, use the oninput native event of the input element and get the current input value.

<input type="text" @bind="@inputValue" @oninput="OnInputEvent" />

@inputValue

@code {
    private string inputValue = "Hello, world";
    private void OnInputEvent(ChangeEventArgs changeEvent)
    {
        inputValue = (string)changeEvent.Value;
    }
}
