javascript - AngularJS ng-pattern regular expression -


i have following input field accepts price value.

input{      type="text"      name="price"      np-currency=true     ng-model='price'     ng-pattern="/[$,.]\d*$/" }

this pattern("/[$,.]\d*$/") makes input field invalid $25.34@@@c%34 correct 25 becomes invalid thats because not have either $ or , or. how make optional?

i need $25.00 or 25 valid not $25.00$%#$%%@@.

requirement: digits $, , . valid

i appreciate suggestions on regular expression.
