棱镜js如何在自定义指令上观察属性以接受要绑定的角度值

这是我到目前为止:

<tile title="Sleep Duration" data-value="{{sleepHistory.averageSleepTime}}"/>

app.directive('tile', [function() {
    return {
        restrict: 'E',
        link: function(scope, element, attrs) {
            var title = attrs.title;

            attrs.$observe('dataValue', function(val) {
                var data = val;

                console.log(data);

                var dom =
                    "<div>" +
                    "<p>" + title + "</p>" +
                    "<p>" + data + "</p>" +
                    "</div";

                $(element).append($(dom.trim()));
            });
        }
    };
}]);

但观察到的值是未定义的

当我使用checked ="checked"时,ng-model会阻止默认情况下选中单选按钮.有谁知道是什么原因引起的？

<input type="radio" name="unitMiles" checked="checked" id="unitMiles" value="Miles" ng-model="unit" ng-change='nextActivityStep(3)'>

如何使用liquibase创建复合索引？

这是我到目前为止:

    <createIndex indexName="idx_value"
                 tableName="test">
        <column name="value"/>
    </createIndex>

我有以下几点,但我只需要确认一下.

<createIndex indexName="idx_value"
             tableName="test">
    <column name="value0"/>
    <column name="value1"/>
</createIndex>

如何使用jasmine对此代码段进行单元测试？

    $scope.profileObject = ProfilesSharedObject;

$scope.$watch("profileObject.startDate", function() {
    var startDate = $scope.profileObject.startDate._d;
    var endDate = $scope.profileObject.endDate._d;

    var newStartDate = moment(startDate).format("YYYY-MM-DD");
    var newEndDate = moment(endDate).format("YYYY-MM-DD");

    $scope.startDate = moment(startDate).format("MM/DD");
    $scope.endDate = moment(endDate).format("MM/DD/YYYY");

    $scope.getSleepData(newStartDate, newEndDate);
});

其中ProfileSharedObject是一个角度js服务

如何计算 11:59:00 PM 和 12:00:00 AM 的平均时间，以便它可以是 11:59:30 PM。目前这段代码给我的是 11:59:30 AM

       var convertTimeToMilliSecondsTest = function(time) {
                  var startDate = "1970/01/01";                         
       if(time.indexOf("AM") != -1) {
          newTime = time.replace("AM", " AM");
       } else if(time.indexOf("PM") != -1) {
          newTime = time.replace("PM", " PM");
       }
          var dateString = startDate + " " + newTime;
          var date = new Date(dateString.replace(/-/g, '/'));                                 
          return date.getTime();
       }

         var calculateAverageTimeToBed = function(dataset) {
                 var totalTimeInMilliSeconds = 0;

                 for(var i = 0;i < dataset.length; ++i) {
                       totalTimeInMilliSeconds += convertTimeToMilliSecondsTest(dataset[i].startTime);
                 } …

对于使用C++的初学者来说,哪个gui库对于跨平台是有益的

Angular JS如何以这样的方式监控击键：html中的输入字段不接受非数字值，而每次击键只接受整数和浮点数？

<form name="myForm">
  <input ng-pattern="/^(?=.+)(?:[1-9]\d*|0)?(?:\.\d+)?$/" ng-model="value" name="number"/>
  Valid? {{myForm.number.$valid}}
</form>

我正在尝试向angularjs应用程序添加常量,但我得到了未定义的错误.

var appConstants = {

};

var appErrorMsgs = {
    loginFail: "Login failed, please check your credentials"
};



var URI_PATH = {
    registration: "/registration",
    seasons: "/seasons",
    vip: "vip",
};

angular.module('app.constants', []).
    constant('CONST', appConstants).
    constant('ERROR_MSG', appErrorMsgs).
    constant('URI_PATH', URI_PATH);

var app = angular.module('AppName', ['snap', 'ngRoute','ngResource','ngTouch','angular-carousel','FSControllers', 'FSPartials','FSDirectives', 'kinvey', 'app.constants']);
