Now we need to work on the Angular code, the main part of this article. Here I first created a module named "app". The module creation is a necessary part if you want to use Angular.

We often get requirements that the input boxes for entering these numbers should only allow digits 0,1,2,3,4,5,6,7,8,9 in order to avoid human errors. This post will describe an Angular directive digitOnly that we are using to make input boxes only accept digits. The ideas in this directive are also applicable to other frameworks.
To sum up, number input is not appropriate for use cases described above. The pattern attribute works with the following input types: textdatesearchurltelemailand password. With the help of the pattern attribute, we can have an input element as follows. The above input box will validate an input value based on the provided regular expression when a user submits a form.

Or you can ignore HTML5 form validation and use form validations in front-end frameworks. This solution is slightly better than the above one using number input.
The good side of this solution is simple and easy. However, you might have noticed that the input type text accepts letter keystrokes and accepts any pasted text.

A few things have changed in Angular. First of all, tools that allow us to transform data are no longer called Filters they are now called Pipes. You can view the official documentation for them here. Angular comes with a few built in Pipes, many of them are the same as the ones that came with Angular JS.
How to validate that input string contains only alphabets, validating that textbox contains only alphabets letterso here is some of the ways for doing such task. Next the match method of string object is used to match the said regular expression against the input value.
