正则表达式匹配精确词

Question

I have two inputs for registration part of my project:

1. password <input type="password" ng-model="userData.password">
2. confirm password <input type="password" ng-model="userData.confirmPassword">

I am using ng-pattern to check if userData.confirmPassword is exactly same as userData.password using this:

<input ng-pattern="^userData.password$" ng-model="userData.confirmPassword">

The problem with the current code is that:

• If password is stackoverflow and confirm passwors is 123stackoverflow123, the regex will still match and will return true for my form.

What regex can I place to match only if the whole text is matching?

根据文档，建议进行以下更改：

<input ng-pattern="{{userData.password}}" ng-model="userData.confirmPassword">
