In this episode, we tackle a common usability issue: scrolling to a specific box or section on the page. Instead of tediously scrolling manually, we start out by adding a handy form right next to our count component. This form lets you input the number of the box you want to jump to and hit Go.
We build the form piece by piece, including a number input field (with validation for a minimum and maximum value), a label, and a Go button. Then, we hook up the input to a Vue ref, so the value is tracked in our app's state.
Once that's set up, we wire up the form submission to a custom goToBox function. This function uses our scroller's API to scroll directly to the box the user entered. We test it out, scrolling all the way down to some impressively large box numbers to make sure it works. Plus, thanks to client-side validation, users can't enter negative numbers or values outside the allowed range.
That's it! By the end of this episode, you'll have a smooth and user-friendly way for users to navigate directly to any box, no more endless manual scrolling.
