参考情報

This is not known limitation. When a timeSlider.play() function is called, the thumbs immediately jump to the next 'stop' and then pause for the playRate time period. The observed behavior when explicitly defining a ViewModel is by design. When properties are defined at the widget level there is a perceived pause. This is because the widget is still hydrating the view model and is unable to perform the first movement. This is the reason with the 5 seconds delay. To remove the delay, the user should wait for the widget to fully initialize as shown below. timeSlider.when(() => { timeSlider.play(); }); If the user would like to pause the playing for a prescripted about of time then I would suggest something like as follows. // Wait three seconds after TimeSlider has fully loaded to play. timeSlider.when(async () => { const pause = new Promise((resolve) => { setTimeout(() => { resolve(); }, 3000); }); await pause; timeSlider.play(); });

対処法

Define all property values for the Time Slider widget directly, without using ‘viewModel’ property.
Do not use the ‘play()’ method to start the slider animation automatically.
