HTML `inputmode` for Specific Input Types
Article Introduction：inputmode is an attribute in HTML that prompts the mobile terminal to display a specific virtual keyboard type. It does not change the input format but improves the experience. Common values include text, tel, url, email, numeric, and decimal. They are suitable for different scenarios, such as tel for phone numbers, decimal for amounts, and numeric for quantity, while the search box is kept text. When using it, you need to pay attention to the difference between it and type. Inputmode is more suitable for scenarios where only the keyboard type is needed without changing the input behavior. It can optimize the input effect with pattern, but it cannot be replaced by single verification, and excessive use should be avoided.

Explain Vue data binding methods?
Article Introduction：There are three main ways to bind Vue: interpolation expression, v-model and v-bind. 1. Interpolation expression ({{}}) is used for text content display, such as {{username}} will be automatically updated with data changes; 2. v-model implements two-way binding of form input, such as keeping the input box synchronized with the data; 3. v-bind dynamic binding attributes, such as: src binding image address. Responsive data needs to be defined in data, new attributes need to be added with $set method, and array operations need to be pushed/pop and other methods. Pay attention to the type when binding values. For example, v-model.number ensures that the input is a number, and class binding requires a Boolean value. Mastering these details can make data binding more straightforward
