I want an ng-pattern expression to validate a textbox in AngularJS JavaScript. Contents for this textbox must have at least one Alphabetic character, but may also contain any number of Numeric and/or Special characters.

Examples:

  1. a1234$ It is acceptable (because 'a' is present)
  2. 123% It is not acceptable
  3. abc It is acceptable
  4. 56456a It is acceptable
  5. 123$%^abc It is acceptable

Use ng-pattern like this. 

<input type="text" ng-model="price" name="price_field" ng-pattern="/.*[a-zA-Z]+.*/" required>

If all you need is to check if there is atleast one alphabet in the string you're matching then you can use the following pattern :

".*[a-zA-Z]+.*"
