从angularjs更改bootstrap进度条宽度

Question

我是Angularjs的新手,当我的控制器中的值发生变化时,我正在尝试更新进度条的宽度.

我有类似的东西:

<span id="percentage">$ {{getTotal()}} ({{getPercentage()}}%)</span>
<div class="progress-bar progress-bar-warning" 
  role="progressbar" aria-valuenow="10" aria-valuemin="0" 
  aria-valuemax="100" style="width: 10%">
    <span class="sr-only">10% Complete (warning)</span>
</div>

我在我的控制器中有类似的东西:

$scope.total = 254.78;
$scope.threshold = 15000;

$scope.getPercentage = function () {
    return (($scope.total * 100) / $scope.threshold).toFixed(2);
}
$scope.getTotal = function () {
    return $scope.total;
}

如何更新进度条的宽度值？

谢谢,Alberto.

Answer 1

ng-style指令可以解决问题.

<span id="percentage">$ {{getTotal()}} ({{getPercentage()}}%)</span>
<div class="progress-bar progress-bar-warning" 
  role="progressbar" aria-valuenow="{{getPercentage()}}" aria-valuemin="0" 
  aria-valuemax="100" ng-style="{width : ( getPercentage() + '%' ) }">
    <span class="sr-only">{{getPercentage()}}% Complete (warning)</span>
</div>
