The new form element types in html5 are: 1. email type; 2. url type; 3. number type; 4. range type; 5. date selector type (date, month, week, time etc.); 6. search type; 7. color type; 8. tel type.
The operating environment of this tutorial: Windows 7 system, HTML5 version, Dell G3 computer.
HTML forms are used to collect different types of user input. In HTML forms, the element is the most important form element. Elements have many forms. According to different type attributes, the type types in the original HTML form include text, password, radio, submit, etc. In the new HTML5, there are multiple new form input types. These new features provide better input control and validation.
This article will introduce the following new form element input types:
- url
- number
- range
- Date pickers (date, month, week, time, datetime, datetime-local)
- search
- color
- tel
email type
When the type attribute is set to email, when submitting the form, it will automatically verify whether the value of the email field conforms to the standard format of email, and you no longer need to use regular expressions yourself. I went to verify the format of the email.
Example
Email:<input type="email" name="useremail" />
url type
When the type attribute is set to url, when the form is submitted, it will automatically verify whether the value of the url field conforms to the standard format of the url.
Example
Linkpage:<input type="url" name="link_url" />
number type
When the type attribute is set to number, it will automatically check whether the input content is of numeric type. You can also set the input box number restrictions.
Example
Number:<input type="number" name="user_num" min="1" max="10" />
For numerically qualified attributes:
Attribute | Description |
---|---|
max | Specifies the maximum value allowed |
min | Specifies the minimum value allowed |
step | Specifies the legal number interval (if step="3", the legal number is -3,0,3,6, etc.) |
value | Specifies the default value |
disabled | Specifies that the input field is disabled |
maxlength | Specifies the maximum character length of the input field |
pattern | Specifies the pattern used to validate the input field |
readonly | Specifies that the value of the input field cannot be modified |
required | Specifies that the value of the input field is required |
size | Specifies the visible characters of the input field |
range type
range type is used for An input field that should contain numeric values within a range. Range types are displayed as sliders. You can also set limits on the numbers that are accepted.
Example
<input type="range" name="user_range" min="1" max="10" />
The attributes used for number qualification are the same as the first four of the number type.
Date Pickers Date picker type
is used to select dates and times.
Example
Date:<input type="date" name="user_date" />
Input type for selecting date and time:
- date selects day, month, year
- month selects month, Year
- week Select week and year
- time Select time (hours and minutes)
- datetime Select time, day, month, year (UTC time, time zone)
- datetime-local Select time, day, month, year (local time)
search type
is used for search fields, such as site search or Google search (search field behaves like a regular text field).
Example
Search Google:<input type="search" name="googlesearch">
color type
When the type attribute is set to color, it will automatically check whether the input content is in color format.
Example
Select your favorite color:<input type="color" name="favcolor">
tel type
When the type attribute is set to tel, it will automatically check whether the input content is in the phone number format.
Example
Telephone:<input type="tel" name="usrtel">

React is a JavaScript library developed by Meta for building user interfaces, with its core being component development and virtual DOM technology. 1. Component and state management: React manages state through components (functions or classes) and Hooks (such as useState), improving code reusability and maintenance. 2. Virtual DOM and performance optimization: Through virtual DOM, React efficiently updates the real DOM to improve performance. 3. Life cycle and Hooks: Hooks (such as useEffect) allow function components to manage life cycles and perform side-effect operations. 4. Usage example: From basic HelloWorld components to advanced global state management (useContext and

The React ecosystem includes state management libraries (such as Redux), routing libraries (such as ReactRouter), UI component libraries (such as Material-UI), testing tools (such as Jest), and building tools (such as Webpack). These tools work together to help developers develop and maintain applications efficiently, improve code quality and development efficiency.

React is a JavaScript library developed by Facebook for building user interfaces. 1. It adopts componentized and virtual DOM technology to improve the efficiency and performance of UI development. 2. The core concepts of React include componentization, state management (such as useState and useEffect) and the working principle of virtual DOM. 3. In practical applications, React supports from basic component rendering to advanced asynchronous data processing. 4. Common errors such as forgetting to add key attributes or incorrect status updates can be debugged through ReactDevTools and logs. 5. Performance optimization and best practices include using React.memo, code segmentation and keeping code readable and maintaining dependability

The application of React in HTML improves the efficiency and flexibility of web development through componentization and virtual DOM. 1) React componentization idea breaks down the UI into reusable units to simplify management. 2) Virtual DOM optimization performance, minimize DOM operations through diffing algorithm. 3) JSX syntax allows writing HTML in JavaScript to improve development efficiency. 4) Use the useState hook to manage state and realize dynamic content updates. 5) Optimization strategies include using React.memo and useCallback to reduce unnecessary rendering.

React's main functions include componentized thinking, state management and virtual DOM. 1) The idea of componentization allows splitting the UI into reusable parts to improve code readability and maintainability. 2) State management manages dynamic data through state and props, and changes trigger UI updates. 3) Virtual DOM optimization performance, update the UI through the calculation of the minimum operation of DOM replica in memory.

The advantages of React are its flexibility and efficiency, which are reflected in: 1) Component-based design improves code reusability; 2) Virtual DOM technology optimizes performance, especially when handling large amounts of data updates; 3) The rich ecosystem provides a large number of third-party libraries and tools. By understanding how React works and uses examples, you can master its core concepts and best practices to build an efficient, maintainable user interface.

React is a JavaScript library for building user interfaces, suitable for large and complex applications. 1. The core of React is componentization and virtual DOM, which improves UI rendering performance. 2. Compared with Vue, React is more flexible but has a steep learning curve, which is suitable for large projects. 3. Compared with Angular, React is lighter, dependent on the community ecology, and suitable for projects that require flexibility.

React operates in HTML via virtual DOM. 1) React uses JSX syntax to write HTML-like structures. 2) Virtual DOM management UI update, efficient rendering through Diffing algorithm. 3) Use ReactDOM.render() to render the component to the real DOM. 4) Optimization and best practices include using React.memo and component splitting to improve performance and maintainability.
