I need to develop a shoe size calculator that converts between male and female sizing on my online store. The math is straightforward - adding 1.5 to convert from men’s to women’s sizes and subtracting 1.5 for the opposite direction.
I want to implement this using JavaScript and HTML as a single component that customers can use on one specific page. My background includes solid Python skills and basic knowledge of JavaScript and HTML, but I’m still learning frontend development.
What would be the best approach to create this interactive tool? Should I use form inputs with event listeners, or are there better methods? Any guidance on structuring the HTML and JavaScript would be really helpful.
I built something like this last year. HTML input with JavaScript event handling works great for shoe size converters. Skip complex form validation - just use input type=“number” with min/max attributes. Most shoe sizes are between 4-15 anyway. Handle edge cases well, like decimals or crazy size ranges. I added a small setTimeout delay so it doesn’t convert on every keystroke - feels way more polished. Pro tip: show both original and converted sizes at the same time instead of replacing the input value. People want to see both numbers when they’re shopping.
i agree with that! using oninput is a solid idea, it makes things feel smooth. just remember to validate inputs tho, ensures users are inputting correct sizes. good luck with your project!
