Question

我想使用带有getDay()方法的switch语句。

这是我正在使用的switch语句。我希望根据当天返回不同的数据。

switch (new Date().getDay()) {
case 0:
    day = "Sunday";
    break;
case 1:
    day = "Monday";
    break;
case 2:
    day = "Tuesday";
    break;
case 3:
    day = "Wednesday";
    break;
case 4:
    day = "Thursday";
    break;
case 5:
    day = "Friday";
    break;
case 6:
    day = "Saturday";
}

这是我想要在星期一返回的数据示例。

 $scope.suggest1("monday-id", function(sItem) {
      if (sItem !== null) {
        $scope.suggestion = sItem.id;
        $scope.name = sItem.name;
        $scope.price = sItem.price;
        }
     });

我不确定如何将它们联系起来，所以任何帮助都会很棒，因为我还在学习，找不到类似的问题或例子。

这个问题缺少一些细节，但这就是我要做的。

angular.module('myapp', []).controller('myctrl', [
  '$scope', function($scope) {
    var getDay, getDayDetails;
    getDayDetails = function(day) {
      var details;
      details = [
        {
          0: {name: 'sun',price: '0'},
          1: {name: 'mon',price: '1'},
          2: {name: 'tue',price: '2'},
          3: {name: 'wed',price: '3'},
          4: {name: 'thu',price: '4'},
          5: {name: 'fri',price: '5'},
          6: {name: 'sat',price: '6'}
        }
      ];
      return $scope.todayDetails = details[0][day];
    };
    getDay = function(date) {
      console.log("called");
      switch (date) {
        case 0:
          getDayDetails(0);
          break;
        case 1:
          getDayDetails(1);
          break;
        case 2:
          getDayDetails(2);
          break;
        case 3:
          getDayDetails(3);
          break;
        case 4:
          getDayDetails(4);
          break;
        case 5:
          getDayDetails(5);
          break;
        case 6:
          getDayDetails(6);
      } 
    };
    $scope.getDay = function(day) {
        $scope.day = getDay(day);
        return console.log("scope.day is ", $scope.day);
    };
    getDay(new Date().getDay());
  }
]);



<div ng-app="myapp" ng-controller="myctrl">
    <pre>{{todayDetails}}</pre>
</div>

或详细信息也可以不是数组，您在对象中拥有与当天匹配的ID，您可以遍历所有日期并提取所需的日期。

使用带有getDay（）方法的switch语句？
