To correctly handle mouse events on HTML5 canvas, first add an event listener to canvas, then calculate the coordinates of the mouse relative to canvas, then judge whether it interacts with the drawn object through geometric detection, and finally realize interactive modes such as drag and drop. 1. Use addEventListener to bind mousedown, mousemove, mouseup and mouseleave events for canvas; 2. Use getBoundingClientRect method to convert clientX/clientY to coordinates relative to canvas; 3. Detect mouse through manual geometric calculations (such as the distance formula of rectangle boundary or circle)

defer is used to perform specified operations before the function returns, such as cleaning resources; parameters are evaluated immediately when defer, and the functions are executed in the order of last-in-first-out (LIFO); 1. Multiple defers are executed in reverse order of declarations; 2. Commonly used for secure cleaning such as file closing; 3. The named return value can be modified; 4. It will be executed even if panic occurs, suitable for recovery; 5. Avoid abuse of defer in loops to prevent resource leakage; correct use can improve code security and readability.

Make sure both tables use the InnoDB engine, MyISAM does not support foreign keys; 2. The referenced column must have an index (such as primary key or unique key); 3. The foreign key column and the data type of the referenced column must be exactly matched (including UNSIGNED, length, etc.); 4. Use the "Structure" tab of phpMyAdmin to add indexes to the foreign key column; 5. Click "Relationship View", select the foreign key column and associate it with the corresponding column of the target table; 6. Set the ONDELETE and ONUPDATE rules and save it; or use SQL statements to add foreign key constraints through ALTERTABLE; 7. If an error is reported, check the engine type, index, data type consistency and existing data integrity. The foreign key will be successfully created after the operation is completed.

First, load BootstrapCSS and JS through CDN, and add integrity and crossorigin attributes to enhance security; 2. Add a detection script after the CSS link to check whether document.getElementById('bootstrap-css').sheet exists. If it does not exist, dynamically insert the local CSS file; 3. For JS, check whether typeofbootstrap==='undefined' is true, and if it is true, create a script tag to load the local JS file; 4. Ensure that the local file path is correct and the version is consistent with the CDN to achieve seamless downgrade. By the CDN fails

const_cast is used to add or remove the const/volatile attribute. It is only applicable to pointers, references, or pointers to members and cannot be used for primitive type conversion. 1. When the original object is not const, it is legal to modify its value through const_cast; 2. If the original object is a real const object, modification will lead to undefined behavior; 3. Common uses include calling the legacy non-const interface and implementing the reuse between const and non-const member functions, such as calling the non-const version in the const function to avoid code duplication. It is necessary to ensure that the object itself is modifiable, otherwise the behavior is undefined.

To resolve the "Windowscannotbeinstalledtothisdisk" error, you must convert the MBR disk to GPT format, because the UEFI system only supports GPT disk installation Windows; 2. Press Shift F10 on the Windows installation interface to open the command prompt, enter diskpart, listdisk, selectdiskX (X is the target disk number), clean, convertgpt, exit, and then refresh and continue the installation; 3. The optional but not recommended method is to enter the BIOS to enable CSM and LegacyBoot mode to support MBR disk installation; 4. Preventive measures include using the latest M

Make sure Edge is set as the default browser and takes over all protocol types; 2. Restore the default configuration by repairing or resetting Edge; 3. Check the link opening settings of other applications (such as emails and Teams); 4. Clear suspicious protocol handlers in Edge; 5. Troubleshoot antivirus software or third-party plug-in conflicts; 6. Update Windows and Edge to the latest version; 7. Create a new user account to test whether it is a user configuration problem, which can ultimately solve the problem that Edge cannot open the link correctly.

assert is a macro used for debugging in C. It is defined in the header file to check whether the condition is true; 2. When the condition is false, the program terminates and outputs error messages such as file name, line number, etc.; 3. Assert only takes effect in debug mode, if the NDEBUG macro is defined, it will be ignored; 4. It is not used to handle general errors such as user input, and is only used to detect internal logic errors of the program; 5. Custom prompt information can be added through assert (condition&&"message"); 6. Examples include checking that the divisor is not zero and the array index is out of bounds, helping to catch errors in the development stage; using assert can effectively improve the efficiency of code debugging, but it should be noted.

First try to force restart and turn off the fast boot, enter the BIOS to disable FastBoot to ensure normal hardware initialization; 2. Unplug all external devices, keep only the keyboard and mouse, and troubleshoot startup stutter caused by faulty peripherals; 3. Re-plug and unplug the memory stick and clean the slots, check whether the graphics card and power cord are connected firmly, and test a single memory one by one if necessary; 4. Disconnect the data cable of the main hard disk or SSD to determine whether the self-test cannot be passed due to storage device failure; 5. Clear CMOS to reset the BIOS settings, and restore the default configuration by jumper or remove the battery discharge; 6. Pay attention to whether there are any alarm sounds or signs of overheating during booting, and use the motherboard manual to interpret beepcode to judge hardware failure; 7. Use a bootable USB disk to try to boot from the external system

First check whether the touchpad is disabled, try to enable it using function keys (such as Fn F7) or physical switch, and confirm that the touchpad switch is on in the settings; 2. Update or reinstall the touchpad driver, find the corresponding device through the device manager and update or uninstall it and restart it to automatically reinstall; 3. If the settings show "Your PC does not have a touchpad", you need to visit the official website of the notebook manufacturer to download and install the correct touchpad driver; 4. Run the built-in hardware and device troubleshooting tools of Windows to automatically detect and fix problems; 5. Check the BIOS/UEFI settings to ensure that the internal touchpad or pointer device is not disabled; 6. Make sure that the Windows system has been updated to the latest version to obtain the latest hardware compatibility support, and finally

In Java, this keyword is used to refer to the current object instance, and its core uses include: 1) distinguishing instance variables and parameters with the same name; 2) calling other constructors in the constructor to implement the constructor chain; 3) passing the current object as a parameter; 4) returning the current object from the method to implement the method chain. For example, use this.name=name in the constructor to explicitly assign instance variables; call other constructors through this() to avoid code duplication; use someMethod(this) to pass the current object into other methods; or use returnthis to implement continuous calls to improve code readability and simplicity.
