Mobile number validation is an important aspect of any form that requires user inputs. In this article, we will be discussing the 10 digit mobile number validation pattern in JavaScript with code examples. A valid mobile number should be 10 digits in length, and can contain numbers only.
To validate a mobile number in JavaScript, we can use regular expressions. A regular expression is a pattern that can be used to match, search, and manipulate text. In JavaScript, regular expressions are represented by the RegExp object.
Here is a regular expression pattern for validating a 10 digit mobile number:
/^\d{10}$/
This pattern will only match a string that contains 10 digits. The ^ symbol at the beginning of the pattern indicates the start of the string, while the $ symbol at the end of the pattern indicates the end of the string. The \d symbol is a shorthand character class that matches any digit. The {10} repetition specifies that the pattern must occur exactly 10 times.
Now, let's see how we can use this pattern in JavaScript code to validate a mobile number.
function validateMobileNumber(mobileNumber) {
var pattern = /^\d{10}$/;
return pattern.test(mobileNumber);
}
In the code above, we have defined a function validateMobileNumber that takes a mobile number as its argument. Inside the function, we have declared a variable pattern that contains the regular expression pattern for a valid mobile number. The test method of the RegExp object is used to test if the provided mobile number matches the pattern. The method returns true if the pattern is found in the string, and false otherwise.
Here are some examples of how to use this function:
console.log(validateMobileNumber("1234567890")); // true
console.log(validateMobileNumber("123456789")); // false
console.log(validateMobileNumber("12345678a9")); // false
In the examples above, the function returns true for the valid 10 digit mobile number 1234567890, and false for an invalid 9 digit mobile number 123456789 and an invalid mobile number containing a letter 12345678a9.
In conclusion, we have discussed the 10 digit mobile number validation pattern in JavaScript with code examples. By using regular expressions, we can validate a mobile number in an efficient and effective manner. This pattern can be used to validate user inputs in forms and ensure that only valid mobile numbers are accepted.
In addition to the 10 digit mobile number validation pattern, it's also important to consider other validations that should be performed when collecting user inputs.
-
Length validation: In some cases, the length of the mobile number may be different than 10 digits. It's important to check the length of the entered mobile number and ensure that it matches the expected length.
-
Formatting validation: Mobile numbers may be formatted in different ways. For example, they may contain spaces, dashes, or parentheses. It's important to remove these formatting characters and check the actual digits before performing the validation.
-
Country code validation: In some cases, the mobile number may be preceded by a country code. It's important to validate the country code and ensure that it matches the expected value.
-
Type validation: In some cases, the mobile number may be of a different type, such as a landline number or a VoIP number. It's important to validate the type of the entered number and ensure that it matches the expected value.
In addition to these validations, it's also important to consider the user experience when collecting user inputs. A user-friendly form should provide clear instructions and feedback to the user. For example, if the entered mobile number is invalid, the form should display an error message indicating what is wrong with the entered value.
In conclusion, it's important to consider not only the 10 digit mobile number validation pattern but also other validations and the user experience when collecting user inputs. By taking these factors into consideration, you can ensure that the collected data is accurate and that the user experience is positive.
