Validating Phone Numbers with Multiple Formats in JavaScript
The task of validating phone numbers can be simplified with regular expressions. While a JavaScript code snippet efficiently checks for phone numbers in two formats, adding another format requires a slightly modified regular expression.
Regular Expression for Multiple Formats
To accommodate the ten-digit format, the improved regular expression is:
/^[\+]?[0-9]{0,3}\W?+[(]?[0-9]{3}[)]?[-\s\.]?[0-9]{3}[-\s\.]?[0-9]{4,6}$/im
This regular expression covers the following formats:
- (123) 456-7890
- (123)456-7890
- 123-456-7890
- 123.456.7890
- 1234567890
Benefits of the Improved Regular Expression
- Accepts phone numbers in multiple formats, including ten-digit consecutive numbers.
- Allows for optional country codes ([ 0-9]).
- Supports various separators (including parentheses, dashes, dots, and spaces).
- Ignores non-numeric characters such as spaces and hyphens.
Usage Example
To use this regular expression, follow these steps:
- Create a variable to store the phone number to be validated.
- Call the test() method of the regular expression with the phone number as an argument.
- If the method returns true, the phone number is valid, otherwise it is invalid.
Conclusion
The enhanced regular expression provides a robust solution for validating phone numbers in multiple formats, making it ideal for handling user inputs in a variety of scenarios.

The following points should be noted when processing dates and time in JavaScript: 1. There are many ways to create Date objects. It is recommended to use ISO format strings to ensure compatibility; 2. Get and set time information can be obtained and set methods, and note that the month starts from 0; 3. Manually formatting dates requires strings, and third-party libraries can also be used; 4. It is recommended to use libraries that support time zones, such as Luxon. Mastering these key points can effectively avoid common mistakes.

What is event bubbling and capturing in the DOM?
Jul 02, 2025 am 01:19 AM
Event capture and bubble are two stages of event propagation in DOM. Capture is from the top layer to the target element, and bubble is from the target element to the top layer. 1. Event capture is implemented by setting the useCapture parameter of addEventListener to true; 2. Event bubble is the default behavior, useCapture is set to false or omitted; 3. Event propagation can be used to prevent event propagation; 4. Event bubbling supports event delegation to improve dynamic content processing efficiency; 5. Capture can be used to intercept events in advance, such as logging or error processing. Understanding these two phases helps to accurately control the timing and how JavaScript responds to user operations.
