angularjs自定义指令检验两次输入的密码是否一致

一、angularjs自定义指令检验两次输入的密码是否一致

'use strict';

ResetPasswordApp.directive('pwCheck', [function () {
    return {
        restrict: 'A',
        require: "ngModel",
        link: function(scope, elem, attrs, ctrl) {
            var otherInput = elem.inheritedData("$formController")[attrs.pwCheck];
            ctrl.$parsers.push(function(value) {
                ctrl.$setValidity("pwCheck",value === otherInput.$viewValue);
                return value;
            });

            otherInput.$parsers.push(function(value) {
                ctrl.$setValidity("pwCheck", value === ctrl.$viewValue);
                return value;
            });
        }
    };
}]);

<form ng-controller="confimPwFormController" ng-submit="submit()" id="confirmPwForm" name="confirmPwForm">
	<div class="form-group">
		<input type="password" placeholder="请输入新密码" ng-model="confirm.password"  name="password" required=true class="required form-control" />
	</div>
	<div class="form-group">

	</div>
	<div class="form-group">
