Preprocessing statements improve security and performance by separating SQL structures and data. Its core usage steps include: 1. Define a SQL template with placeholders in the preparation stage; 2. Bind parameters and run the execution stage; 3. Release preprocessing resources. The advantage is to prevent SQL injection, because parameters are automatically escaped and the SQL parsing overhead is reduced when multiple executions are performed. Note in the application: placeholders are only used for values and cannot be used for table/column names. Variables need to be declared by @, resources are released in a timely manner, and parameter types are ensured to match. Mainstream languages such as PHP, Python, and Java all support preprocessing mechanisms.

First run SFC to scan and repair the system files. 1. Run the command prompt as an administrator and execute sfc/scannow. If it cannot be repaired, 2. Use the DISM tool to execute the /Dism/Online/Cleanup-Image/CheckHealth, /ScanHealth and /RestoreHealth commands to repair the system image in turn; 3. If it still fails, restart and repeat the SFC and DISM steps after entering safe mode; 4. Finally, you can run chkdskC:/f/r to check for hard disk errors, and restart the computer after the repair is completed. This process can usually solve the problem of crashes, lags or error prompts caused by system file corruption.

A IIFE (call function expression immediately) is a JavaScript function that is executed immediately after definition. It is mainly used to create private scopes, avoid global pollution, and execute code immediately. 1. It is implemented by wrapping the function in parentheses and adding call brackets immediately afterwards: (function(){/code/})(); 2. Using IIFE can prevent variables from leaking to the global scope, such as (function(){varlocalVar="private";})(); ensure that localVar cannot be accessed from externally; 3. Private variables can be created in combination with closures, such as counter object exposing the interface through the return method but hiding privateCount;

Set the name attribute for data identification when submitting the form, and the value attribute defines the submitted value; 5. You can add the required attribute to force selection, or use the multiple attribute to allow multiple selections to finally implement a simple and well-compatible drop-down list.

govet analyzes Go code to find common correctness problems that the compiler cannot catch. 1. Detecting printf formatting errors, such as fmt.Printf("%s",42) will warn of type mismatch; 2. Discovering unreachable code, such as code after return; 3. Checking whether the structure tag is correct, such as json tag format; 4. Preventing the copying of sync.Mutex caused race conditions; 5. Detecting variable masking, useless assignment and method receiver improper use; 6. Running or integrating into CI/CD and editor through govet; 7. As a static checking tool focusing on correctness, it helps to discover potential bugs in the early stage of development and improve code quality, which is recommended.

Use History API to control browser history, 1. Add new history entries through pushState(), 2. Use replaceState() to modify the current entry without adding new history, 3. Listen to the navigation before and after the popstate event processing, 4. Check the URL and state when the page is loaded to correctly initialize the status, 5. Synchronize the URL and interface content when updating the UI, 6. Follow the same-origin policy and use meaningful state objects, thereby achieving a seamless navigation experience in a single-page application.

To create a mailto link containing the topic and body, you need to use URL encoding to add the parameters to the link: 1. Use the mailto: protocol and add subject and body parameters, the format is mailto:email@example.com?subject=...&body=...; 2. Use & separating between parameters; 3. Use encoding for spaces and use newlines for spaces Coding; 4. You can add cc or bcc parameters; 5. Avoid too long content to ensure compatibility; 6. Test on different clients, because the degree of support may vary, the final effect depends on the support status of the user's default email client.
