这应该解决它：
<div ng-controller='Ctrl'>
<form name='form'>
<input data-ng-model='user.password' type="password" name='password' placeholder='password' required>
<div ng-show="form.password.$error.required">
Field required</div>
<input ng-model='user.password_verify' type="password" name='confirm_password' placeholder='confirm password' required data-password-verify="user.password">
<div ng-show="form.confirm_password.$error.required">
Field required!</div>
<div ng-show="form.confirm_password.$error.passwordVerify">
Fields are not equal!</div>
</form
</div>
var app = angular.module('myApp', []);
app.directive("passwordVerify", function() {
return {
require: "ngModel",
scope: {
passwordVerify: '='
},
link: function(scope, element, attrs, ctrl) {
scope.$watch(function() {
var combined;
if (scope.passwordVerify || ctrl.$viewValue) {
combined = scope.passwordVerify + '_' + ctrl.$viewValue;
}
return combined;
}, function(value) {
if (value) {
ctrl.$parsers.unshift(function(viewValue) {
var origin = scope.passwordVerify;
if (origin !== viewValue) {
ctrl.$setValidity("passwordVerify", false);
return undefined;
} else {
ctrl.$setValidity("passwordVerify", true);
return viewValue;
}
});
}
});
}
};
});
