Question

我创建了两个下拉菜单营业时间＆amp;在angularJS中使用ng-options 关闭时间。下拉选项由相同的数组$scope.availableTimes

填充

以下是HTML代码：

<div class="row">
    <div class="col-md-6">
      <div class="form-group">
        <label for="exampleFormControlSelect1">Opening </label>
        <select class="form-control" data-ng-options="time.display for time in availableTimes" data-ng-model="selectedFromTime">
        </select>
      </div>
    </div>
    <div class="col-md-6">
      <div class="form-group">
        <label for="exampleFormControlSelect1">Closing</label>
         <select class="form-control" data-ng-options="time.display for time in availableTimes" data-ng-model="selectedToTime">
        </select>
      </div>
    </div>
  </div>

以下是AngularJS脚本

var app = angular.module('angularjs-starter', []);

app.controller('MainCtrl', function($scope) {
  $scope.availableTimes = [];
  $scope.availableTimes.push({
    'msValue': 0,
    'display': '12:00 Morning'
  });
  for (var msValue = 900000; msValue <= 85500000; msValue += 900000) { // 90.000ms = 15 min, 85.500.000ms = 11:45PM
    $scope.availableTimes.push({
      'msValue': msValue,
      'display': moment(msValue).utc().format("h:mm A")
    })
  }
  var dayMS = 86400000 - 1;
  $scope.availableTimes.push({
    'msValue': dayMS,
    'display': '12:00 Midnight'
  });

  console.log($scope.availableTimes);
});

Plunker

正如你所看到的，这两个下拉列表的时间列表从午夜12点到凌晨12点开始，间隔15分钟。

喜欢这样：

凌晨12:00 上午12:15 上午12:30 上午12:45 .....
.....
晚上11点45分午夜12:00

What I can do to make the Closing Hour drop-down options lists starts with the value that is 15 min greater than Opening hours.

示例：

如果开放时间选择为上午8:00截止时间下拉列表将从上午8:15而不是上午12:00开始。

营业时间
12:00上午 ....
....
上午8:00（选定）
上午8:15 上午8:30 ....
午夜12:00

关闭时间
上午8:00 上午8:15 上午8:30 .......
.......
午夜时分上午12:15 上午12:30 .......
.......
上午7:45

我希望这个例子能说明我想要实现的目标。任何帮助将不胜感激。

Answer 1

我已更新您的代码。

使用此文件：

app.js

Books::where('book_title ','LIKE','%'.$something.'%')
       ->orWhere('book_author ','LIKE','%'.$something.'%')
       ->orWhere('book_description ','LIKE','%'.$something.'%')->get();

的index.html

var app = angular.module('angularjs-starter', []);

app.controller('MainCtrl', function($scope) {
  $scope.availableTimes = [];
  $scope.selectedFromTime = {
    'msValue': 0,
    'display': '12:00 Morning'
  };

 $scope.availableTimes.push($scope.selectedFromTime);

  for (var msValue = 900000; msValue <= 85500000; msValue += 900000) { // 90.000ms = 15 min, 85.500.000ms = 11:45PM
    $scope.availableTimes.push({
      'msValue': msValue,
      'display': moment(msValue).utc().format("h:mm A")
    })
  }
  var dayMS = 86400000 - 1;
  $scope.availableTimes.push({
    'msValue': dayMS,
    'display': '12:00 Midnight'
  });

  $scope.skipValues = function(value, index, array) {
    return value.msValue > $scope.selectedFromTime.msValue ;
};

  console.log($scope.availableTimes);
});
