Angular I want validation on my string

Question

Hello I have one input box here I enter 10 digit string so I want following validation on that entered string

Is there any validation process for this

For example

String should be ABBC12345A

It is valid string so how I add validation on input box in my angular

It should be like to this /^([a-zA-Z]){4}([0-9]){5}([a-zA-Z]){1}$/ — Hadi

As suggested in the comments, you can use regex. There are a few options, this is the way I like do do it.

/^(\w){4}(\d){5}(\w){1}$/

Please try the following:

<input [ngControl]="fullName" pattern="[a-zA-Z ]*">

And here is the documentation for your reference on regex https://www.w3schools.com/jsref/jsref_obj_regexp.asp
