从更改引导angularjs进度条宽度 [英] Change bootstrap progress-bar width from angularjs

问题描述

我在Angularjs新我想更新进度条的宽度时，在我的控制器变化的值。

I'm new in Angularjs and I am trying to update the width of a progress bar when a value in my controller change.

我有这样的：

<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>

和我有我的控制器是这样的：

And I have in my controller something like:

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

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

我如何更新进度条的宽度值？

How do I update the width value of the progress bar?

谢谢，
阿尔贝托。

Thanks, Alberto.

推荐答案

纳克风格的指令会做的伎俩。

ng-style directive would do the trick.

<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>
