How do you use the target attribute for links in HTML5?

How do you use the target attribute for links in HTML5?

Use the target attribute to control the opening position of the link, 1. Use _self to open on the current page (default); 2. Use _blank to open external links in the new tab page, and rel="noopener" must be added to ensure security; 3. Use _parent to open in the parent framework; 4. Use _top to open in the top window to jump out of the framework; _blank should be used with caution, only for external links or download pages to avoid interfering with the user's browsing experience, and in the end, default _self is usually the best.

MacBook won't detect external monitor

MacBook won't detect external monitor

MacBooks do not recognize external monitors are usually caused by connection, setup, or compatibility issues, rather than hardware corruption. 1. Check whether the cable is intact and whether the interface is tight, and confirm that the monitor power and input source are correct; 2. Try to restart the system, reset the display settings or use safe mode to troubleshoot software conflicts; 3. Adjust the resolution/refresh rate or update the monitor firmware to improve compatibility; 4. Further troubleshoot through third-party tools, terminal commands or create a new user account; 5. If the above steps are invalid, it is recommended to detect the monitor itself or contact professional repairs.

What is the difference between function declaration and function expression in JavaScript?

What is the difference between function declaration and function expression in JavaScript?

Function declarations are directly defined using the function keyword, and function expressions assign functions to variables; 2. Function declarations are completely improved and can be called in advance, function expressions are only variable promotion and cannot be called in advance; 3. Function declarations are created during parsing, function expressions are created at runtime, and conditional definitions are supported; 4. Function declarations are suitable for scenarios that require advance call and readability, and function expressions are suitable for dynamic assignment, callbacks and conditional logic scenarios. Therefore, function declarations are available earlier and function expressions are executed sequentially.

How to Perform Point-in-Time Recovery Using the Binary Log?

How to Perform Point-in-Time Recovery Using the Binary Log?

To restore the MySQL database to a specific point in time, you must first restore the complete backup, and then use binary logs to replay the changes. The specific steps are: 1. Use mysqldump and other tools to restore the most recent complete backup to bring the database back to the state at the time of backup; 2. Use mysqlbinlog to analyze the binary logs in combination with time range or location information, and locate the time point or event location that needs to be restored; 3. Use mysqlbinlog to read the binary log from the backup time to the target time point, and redirect its output to the MySQL server for execution, thereby replaying all legal operations within this time period; To ensure accuracy, it is recommended to use log location instead of timestamp, and test the recovery process in a non-production environment, and enable-

How does garbage collection work in Golang?

How does garbage collection work in Golang?

Go's garbage collection (GC) is automatic, using a concurrent three-color mark removal algorithm, implements concurrent collection through a write barrier, optimizes short-life cycle object recycling, and maintains low pause time. Developers can improve performance through object reuse and avoids memory leaks. 1.GC marks accessible objects from the root object and clears unreachable objects. 2. Write barrier ensures that reference updates are not omitted during concurrency. 3. Although there is no explicit generational division, it is optimized according to "most objects die prematurely", and short-cycle GC is frequently executed. 4. Only submillisecond pauses will occur at the beginning and end of the mark to ensure low latency. 5. Developers can use sync.Pool to reuse objects to reduce allocation pressure and avoid memory problems caused by long-term holding of large objects or global references. Go's GC runs efficiently in the background and balances
