Please make sure the browser you are using supports sessionStorage!
Want to use sessionStorage? These browsers must support it! Need specific code examples
With the development of the Internet, Web applications are becoming increasingly popular. To improve user experience, developers often use various techniques to create interactive and dynamic web pages. Among them, sessionStorage is a very useful technology that can save and access data in the browser to achieve data transfer and storage during the session.
But before using sessionStorage, we need to make it clear that not all browsers support sessionStorage. According to W3School information, sessionStorage support is as follows:
- Internet Explorer: Supported starting from IE8 version.
- Firefox: Supported starting from Firefox 2 version.
- Safari: Supported starting from Safari 4 version.
- Chrome: Supported starting from Chrome 4 version.
- Opera: Supported from Opera 10.5 version.
If your application needs to be compatible with older browsers, you may want to consider using other solutions, such as cookies or localStorage.
Next, I will provide you with some specific code examples of sessionStorage.
-
Set sessionStorage value
sessionStorage.setItem("key", "value");
-
Get sessionStorage value
var value = sessionStorage.getItem("key");
-
Delete sessionStorage value
sessionStorage.removeItem("key");
-
Clear sessionStorage
sessionStorage.clear();
When dealing with sessionStorage, you need to remember the following points:
- sessionStorage is based on keys Storage mechanism of value pairs, so we need to specify a unique key for each stored value.
- sessionStorage can only store string type values. If you need to store other types of data, you need to perform corresponding conversions.
- sessionSotrage is performed for each browser window (or tab). If the sessionStorage value is set in one tab, other tabs cannot be accessed.
- The sessionStorage data will be cleared after the user closes the browser window. You can also use
sessionStorage.clear()
in the code to clear it manually.
To sum up, sessionStorage is a very useful technology that can save data during the session in the browser and improve the user experience. But before using it, make sure that the target browser supports sessionStorage and follow the usage specifications of the above code examples.

The function of HTML is to define the structure and content of a web page, and its purpose is to provide a standardized way to display information. 1) HTML organizes various parts of the web page through tags and attributes, such as titles and paragraphs. 2) It supports the separation of content and performance and improves maintenance efficiency. 3) HTML is extensible, allowing custom tags to enhance SEO.

The future trends of HTML are semantics and web components, the future trends of CSS are CSS-in-JS and CSSHoudini, and the future trends of JavaScript are WebAssembly and Serverless. 1. HTML semantics improve accessibility and SEO effects, and Web components improve development efficiency, but attention should be paid to browser compatibility. 2. CSS-in-JS enhances style management flexibility but may increase file size. CSSHoudini allows direct operation of CSS rendering. 3.WebAssembly optimizes browser application performance but has a steep learning curve, and Serverless simplifies development but requires optimization of cold start problems.

The roles of HTML, CSS and JavaScript in web development are: 1. HTML defines the web page structure, 2. CSS controls the web page style, and 3. JavaScript adds dynamic behavior. Together, they build the framework, aesthetics and interactivity of modern websites.

The future of HTML is full of infinite possibilities. 1) New features and standards will include more semantic tags and the popularity of WebComponents. 2) The web design trend will continue to develop towards responsive and accessible design. 3) Performance optimization will improve the user experience through responsive image loading and lazy loading technologies.
