After following, you can keep track of his dynamic information in a timely manner
Use the URLSearchParams API to easily obtain URL query parameters, for example: consturlParams=newURLSearchParams(window.location.search); constname=urlParams.get('name'); 2. When processing duplicate parameters, you can use getAll() method to get array values; 3. You can parse custom URLs through URL objects or directly passed in query strings; 4. Note that when the parameter does not exist, the parameter name is case sensitive, the value is a string, and the type needs to be converted manually, and the URL encoding will be automatically decoded; in summary, use newURLSea

Use reflect.TypeOf() and reflect.ValueOf() to get the type and value of the variable, where ValueOf returns a copy; 2. You can traverse the structure field through reflection to obtain the field name, type and label information; 3. Modify the value, you need to pass a pointer and call Elem() to get the addressable value, and you need to check CanSet(); 4. You can traverse the structure field and set a new value according to the type; 5. Get the method through MethodByName() and call it with Call(); 6. You can determine whether the type implements a specific method or interface; the reflection performance is low, so you should avoid using a hot path. When modifying the value, you must pass a pointer. The field that is not exported cannot be modified. Ki is preferred for type judgment:

The method of setting up hanging indentation in Word is as follows: First, select the paragraph, right-click to select "Paragraph" or enter the settings window through the menu bar; secondly, select "Hang" in "Special Indentation" and set the indentation value; finally click "OK" to complete the setting. Hanging indentation is mainly used in document scenarios with strict format requirements such as references. For batch processing of multiple paragraphs, you can select and set them uniformly at one time. Additionally, you can save settings as custom styles for efficiency. After mastering these steps, the suspension indent effect can be efficiently achieved.

The method of creating password fields varies from platform to platform: 1. The implementation of input mask is used in HTML, and verification can be enhanced through required, minlength and other attributes; 2. In React, useState to manage password status, the "Show Password" switching function can be added to improve user experience; 3. Android uses the EditText component of android:inputType="textPassword" in XML to avoid enabling text prediction to enhance security; 4. iOS uses SecureField to automatically hide input content in SwiftUI, prohibiting the recording of password logs; 5.

The recommended way to read files line by line in Python is to use withopen() and for loops. 1. Use withopen('example.txt','r',encoding='utf-8')asfile: to ensure safe closing of files; 2. Use forlineinfile: to realize line-by-line reading, memory-friendly; 3. Use line.strip() to remove line-by-line characters and whitespace characters; 4. Specify encoding='utf-8' to prevent encoding errors; other techniques include skipping blank lines, reading N lines before, getting line numbers and processing lines according to conditions, and always avoiding manual opening without closing. This method is complete and efficient, suitable for large file processing

Check for spelling errors or illegal characters in the path, make sure to use backslashes and avoid using characters such as "|?*; 2. Confirm that the target drive or directory exists, and if you switch the drive, you need to use the cd/d command; 3. Run chkdskC:/f/r to fix file system errors and restore bad sectors; 4. Shorten the excessively long path or move the folder to the root directory, or enable Win32 long path support through group policy or registry; 5. Avoid using CON, PRN, AUX, etc. as folder names; 6. Restart the command prompt and gradually navigate from the root directory to eliminate environment variables or current directory settings problems. This error is usually caused by invalid path, unconnected drive, or system corruption. Follow the steps to troubleshoot.

Use datetime.strptime() to convert date strings into datetime object. 1. Basic usage: parse "2023-10-05" as datetime object through "%Y-%m-%d"; 2. Supports multiple formats such as "%m/%d/%Y" to parse American dates, "%d/%m/%Y" to parse British dates, "%b%d,%Y%I:%M%p" to parse time with AM/PM; 3. Use dateutil.parser.parse() to automatically infer unknown formats; 4. Use .d

Python's multi-threading is suitable for I/O-intensive tasks. 1. Use threading.Thread to manually create threads and control execution; 2. Use ThreadPoolExecutor to manage thread pools more concisely and improve code readability; 3. Although GIL limits the parallelism of CPU-intensive tasks, it can still significantly reduce the total time-consuming in I/O operations such as network requests; 4. Exception processing should be added in actual applications to enhance robustness; 5. This mechanism is widely used in crawlers, API calls and other scenarios, which can effectively improve concurrency efficiency, and the total time-consuming is much lower than serial execution.

Restarting the WindowsAudio service can solve the problem of service stuck. You must also ensure that the WindowsAudioEndpointBuilder service is running and set the startup type to automatic; 2. Updating or reinstalling the audio driver can be automatically updated through the Device Manager, restarting and automatically installing or manually downloading the official driver; 3. Running audio troubleshooting can automatically detect and repair common audio problems; 4. Check the dependency relationship of the WindowsAudio service to ensure that dependent services such as RPC and AudioEndpointBuilder have been started; 5. Clearing the audio cache requires netstopaudiosrv and netsto in the administrator command prompt.

composerinit is an interactive command used to create composer.json files. 1. It will prompt for information such as project name, description, author, license, etc.; 2. Ask for required dependencies and development dependencies; 3. Configure automatic loading, scripts and other settings; 4. Generate composer.json files that meet PHP project standards; 5. Non-interactive automatic configuration can be achieved through parameters such as --no-interaction; this command is suitable for new project initialization and is the easiest way to set up PHP dependency management configuration. After execution is completed, you need to run composerinstall to install the listed dependencies, and will not automatically overwrite the existing composer.js

There are three main ways to generate a number or date sequence in SQL. 1. Use the generate_series() function in PostgreSQL to quickly generate numeric and date sequences, such as SELECTgenerate_series(1,10) to generate numeric numbers from 1 to 10, or combine date parameters to generate dates in a specified range; 2. Use recursive CTE in SQLServer or MySQL to manually construct numeric or date ranges through recursive methods, such as using WITH statements to generate numeric sequences from 1 to 10 or consecutive dates; 3. Use pre-built numeric tables or calendar tables, suitable for all databases, combined with DATEADD and other functions

When you encounter the "theuserprofileservicefailedthesign-in" error, it is usually due to corruption of the user profile or permission exceptions that it cannot load. 1. First try to log in to the system using the administrator account to perform repair operations; 2. Check the ProfileImagePath entry in the registry to ensure there are no conflicts or errors, delete the problem items if necessary and restart; 3. Create a new user and migrate the old user data to bypass the original configuration problem; 4. Ensure that the system disk space is sufficient, and check the repair system file integrity through the sfc/scannow command to resolve the login error.
