Question

我完全是Angularjs的新手，并试图验证2个场景。我有2个文本框，一个带有开始日期，另一个带有结束日期。我正在检查

如果开始日期不大于或等于今天，则在UI上显示验证错误。它应该是今天或今天之后的任何一天。
如果开始日期大于结束日期，则在UI上显示验证错误。结束日期应大于开始日期。

我尝试了以下不起作用的代码。请提出任何建议。

Html代码

<label for="endDate" class="control-label">Start Date:</label>
<div>
    <input type="text" class="form-control" 
           id="startDate" ng-model="startDate" />
</div>

<label for="text" class="control-label">End Date:</label>
<div>
    <input type="text" class="form-control" 
           id="endDate" ng-model="endDate" 
            ng-change='checkErr(startDate,endDate)' />

</div>

<span>{{errMessage}}</span>

js code

$scope.checkErr = function(startDate,endDate){
    $scope.errMessage = '';
    $scope.curDate = new Date();

    if(startDate < endDate){
      $scope.errMessage = 'End Date should be greate than start date';
      return false;
    }
    if(startDate < curDate){
       $scope.errMessage = 'Start date should not be before today.';
       return false;
    }

  };

我有输入类型作为日期控件的文本。我正在使用引导日期选择器。

Answer 1

你在第一位有相反的逻辑，你必须从startDate构建一个新的日期，以便与今天的日期进行比较。您还可以将curDate设置为范围$scope.curDate = new Date()，但之后您将其引用为curDate而没有$scope，因此未定义。最后，您还需要将stateDate和endDate投射到某个日期。否则你只是在比较字符串。

$scope.checkErr = function(startDate,endDate) {
    $scope.errMessage = '';
    var curDate = new Date();

    if(new Date(startDate) > new Date(endDate)){
      $scope.errMessage = 'End Date should be greater than start date';
      return false;
    }
    if(new Date(startDate) < curDate){
       $scope.errMessage = 'Start date should not be before today.';
       return false;
    }
};

Answer 2

看起来您正在引用未定义的curDate。将条件更改为if (startDate < $scope.curDate)。请参阅工具示例的小提琴http://jsfiddle.net/4ec3atzk/1/

$scope.checkErr = function(startDate,endDate){
  $scope.errMessage = '';
  $scope.curDate = new Date();

  if (startDate < endDate){
    $scope.errMessage = 'End Date should be greate than start date';
    return false;
  }

  if (new Date(startDate) < $scope.curDate){
    $scope.errMessage = 'Start date should not be before today.';
    return false;
  }
};

        }


        var year = todayTime.getFullYear();
        return day + "/" + month + "/" + year;
    }

}

        $scope.ToDates = '';

    else {
        var todayTime = new Date(val);

        var month = todayTime.getMonth() + 1;
        var day = todayTime.getDate();


        if (day < 10) {
            day = '0' + day;
        }
        if (month < 10) {
            month = '0' + month;
        }
        var year = todayTime.getFullYear();
        return day + "/" + month + "/" + year;
    }

}
