angularjs 密码一致性校验

angularjs 校验密码字段一致性

directives.directive('pwCheck', function () {
    return {
        require: 'ngModel',
        link: function (scope, elem, attrs, ctrl) {
            var firstPassword = '#' + attrs.pwCheck;
            // 网上好多例子都掉了$(elem) 美元符号和括号
            $(elem).add(firstPassword).on('keyup', function () {
                scope.$apply(function () {
                    alert(elem.val());
                    var v = elem.val()===$(firstPassword).val();
                    ctrl.$setValidity('pwmatch',v);
                });
            });
        }
    };
});
