javascript - 如何在RZslider中绘制减小的showticks在线线条尺寸？

我正在将RZslider与showTicks一起使用。我想减小showTicks的大小。并且请在全屏下方展开以下输出，然后您将能够在滑块上看到showticks。我想减小这些引号的大小。

var app = angular.module('rzSliderDemo', ['rzModule', 'ui.bootstrap']);

app.controller('MainCtrl', function($scope, $rootScope, $timeout) {
  $scope.$watch('dateBirth', function(n, o) {
    var newDay = n || new Date();
    $scope.selectedDate = moment(newDay);
    $scope.selectedDate.hour(moment().hour());
    $scope.selectedDate.minute(0);
    $scope.init();
  });

  $scope.init = function() {
    var startDate, endDate, startTime, endTime;

    var timeData = getRange($scope.selectedDate);
    $scope.localTime = timeData.currentTime; // actually start of this hour

    var arr = timeData.times.map(n => {
      return {
        value: n.value
        //legend: n.value
      };
    });

    $timeout(function(){
      $scope.slider = {
        minValue: $scope.localTime.clone().subtract(4, "hours").format('YYYY DD MMM HH:mm'),
        maxValue: $scope.localTime.clone().add(4, "hours").format('YYYY DD MMM HH:mm'),
        options: {
          showTicks: true,
          stepsArray: arr,
          draggableRange: true,
        }
      };
    });
  }

  $scope.init();
});

function getRange(currentDate) {
  var arr = [];
  var totalHourRange = 32;
  var currentTime = currentDate || moment(); // current date and time using Moment

  // set current time to beginning of the hour
  currentTime.minute(0);

  // clone date and substract 1/2 total range to get start point
var tmpTime = currentTime.clone();
     //tmpTime.subtract(totalHourRange / 2, 'hours');
     tmpTime.hour(0).subtract(4, 'hours');

  // offset is the number of minutes from the current point
  for (var i = -6 * (totalHourRange / 2); i <= 6 * (totalHourRange / 2); i++) {
      arr.push({value: tmpTime.format('YYYY DD MMM HH:mm'), offset: i * 10});
      tmpTime.add(10, 'minutes');
    }
  return { times: arr, currentTime: currentTime, totalHourRange: totalHourRange };
}

      <br />
      <rzslider rz-slider-model="slider.minValue" rz-slider-high="slider.maxValue" rz-slider-options="slider.options"></rzslider>
    </article>
  </div>
</div>

当我减小showticks的大小时，它就不能正确地画在线上。

的CSS

  .rzslider .rz-tick {
    position: absolute;
    top: 0;
    left: 0;
    width: 5px;
    height: 5px;
    margin-left: 11px;
    text-align: center;
    cursor: pointer;
    background: #d8e0f3;
    border-radius: 50%;
}

输出值



我想在每个showticks之间留出空间。我怎样才能清晰地画出趣味性。

最佳答案

我认为您可以仅使用属性ticks指定所需的showTicks数量。例如，如果您只想显示10 ticks，则需要给出showTicks:10，请参见以下示例。

另外，请检查AngularJS Slider Demo Page中的示例演示，在那里我们可以看到showticks:10属性的实现。

注意：由于有很多数据点，我们可以看到滑块没有固定的步长，减少数据点的数量将在滑块中创建步长。

如果此代码对您有帮助，请告诉我！

var app = angular.module('rzSliderDemo', ['rzModule', 'ui.bootstrap']);

app.controller('MainCtrl', function($scope, $rootScope, $timeout) {
  $scope.$watch('dateBirth', function(n, o) {
    var newDay = n || new Date();
    $scope.selectedDate = moment(newDay);
    $scope.selectedDate.hour(moment().hour());
    $scope.selectedDate.minute(0);
    $scope.init();
  });

  $scope.init = function() {
    var startDate, endDate, startTime, endTime;

    var timeData = getRange($scope.selectedDate);
    $scope.localTime = timeData.currentTime; // actually start of this hour

    var arr = timeData.times.map(n => {
      return {
        value: n.value
        //legend: n.value
      };
    });

    $timeout(function(){
      $scope.slider = {
        minValue: $scope.localTime.clone().subtract(4, "hours").format('YYYY DD MMM HH:mm'),
        maxValue: $scope.localTime.clone().add(4, "hours").format('YYYY DD MMM HH:mm'),
        options: {
          showTicks: 10,
          stepsArray: arr,
          draggableRange: true,
        }
      };
    });
  }

  $scope.init();
});

function getRange(currentDate) {
  var arr = [];
  var totalHourRange = 32;
  var currentTime = currentDate || moment(); // current date and time using Moment

  // set current time to beginning of the hour
  currentTime.minute(0);

  // clone date and substract 1/2 total range to get start point
var tmpTime = currentTime.clone();
     //tmpTime.subtract(totalHourRange / 2, 'hours');
     tmpTime.hour(0).subtract(4, 'hours');

  // offset is the number of minutes from the current point
  for (var i = -6 * (totalHourRange / 2); i <= 6 * (totalHourRange / 2); i++) {
      arr.push({value: tmpTime.format('YYYY DD MMM HH:mm'), offset: i * 10});
      tmpTime.add(10, 'minutes');
    }
  return { times: arr, currentTime: currentTime, totalHourRange: totalHourRange };
}
