Hello, I have just one input box where I enter a 10-digit string, and I am looking to apply the following validations to the entered string:
Is there any validation process for this in Angular?
For example:
The string should be ABBC12345A
This would be a valid string, so how can I add this validation to the input box in my Angular application?
Give this a shot
/^([a-zA-Z]){4}([0-9]){5}([a-zA-Z]){1}$/
To tackle this issue, utilizing regex is a recommended approach. There are several possibilities, but this method is my personal preference.
/^(\w){4}(\d){5}(\w){1}$/
^ denotes the start of a string
\w represents any alphabetic character
\d indicates any numerical digit{x} specifies the occurrence of x instances$ signifies the end of a stringIllustrative Example: https://regex101.com/r/abcdef/2
Here are some steps you can take to resolve the issue:
<input [ngControl]="fullName" pattern="[a-zA-Z ]*">
For further information on regular expressions, you can refer to the documentation https://www.w3schools.com/jsref/jsref_obj_regexp.asp
