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

问题描述

我是 Angularjs 的新手，我正在尝试在控制器中的值发生变化时更新进度条的宽度.

我有类似的东西:

<span id="percentage">$ {{getTotal()}} ({{getPercentage()}}%)</span><div class="progress-bar progress-bar-warning"角色="进度条" aria-valuenow="10" aria-valuemin="0"aria-valuemax="100" 样式="宽度:10%"><span class="sr-only">10% 完成(警告)</span>

我的控制器中有类似的东西:

$scope.total = 254.78;$scope.threshold = 15000;$scope.getPercentage = 函数 () {返回 (($scope.total * 100)/$scope.threshold).toFixed(2);}$scope.getTotal = 函数 () {返回 $scope.total;}

如何更新进度条的宽度值?

谢谢，阿尔贝托.

解决方案

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(警告)</span>

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

I have something like:

<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>

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;
}

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

Thanks, Alberto.

解决方案

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>
