How can the inputmode in html attributes improve the user experience on mobile devices?
Article Introduction：inputmode is an attribute in HTML that is used to optimize the mobile input experience. It reduces user input steps by prompting the browser to display a specific virtual keyboard type. For example, setting the phone number input box to inputmode="numeric" can directly call out the numeric keyboard to avoid switching. Common applicable scenarios include: 1. Set the phone number input box to numeric; 2. Use numeric in the amount or zip code field; 3. Search or default can be used in the search box or address bar; Password field is usually not recommended. Commonly used values ??include text, none, decimal, numeric, tel, email and url, etc., and should be flexibly selected according to actual needs.

How to use the pattern attribute for custom form validation?
Article Introduction：The key to using the pattern attribute for form validation is to correctly write regular expressions and pay attention to their scope and limitations. 1. Add pattern attributes to the input element of HTML and set regular expressions to achieve input format verification without JavaScript; 2. Common use cases include format verification such as mobile phone number, password, username, etc.; 3. The default error information can be customized through JavaScript to improve user experience; 4. Note that pattern is only verified when submitting, not all input types support it, and needs to be verified with the server. Rational use of pattern can simplify front-end verification logic, but it must understand its working mechanism and limitations.
