PHP编程：详解Yii2高级版引入bootstrap.js的一个办法

namespace frontend\assets;
use yii\web\AssetBundle;
/**
 * Main frontend application asset bundle.
 */
class AppAsset extends AssetBundle
{
  public $basePath = '@webroot';
  public $baseUrl = '@web';
  public $css = [
    'css/site.css',
  ];
  public $js = [
    'js/main.js',
  ];
  public $depends = [
    'yii\web\YiiAsset',
    'yii\bootstrap\BootstrapAsset',//注意这里必须要有
    'rmrevin\yii\fontawesome\AssetBundle',
  ];
}

namespace yii\bootstrap;
use yii\web\AssetBundle;
/**
 * Asset bundle for the Twitter bootstrap css files.
 *
 * @since 2.0
 */
class BootstrapAsset extends AssetBundle
{
  public $sourcePath = '@bower/bootstrap/dist';
  public $css = [
    'css/bootstrap.css',
  ];
  //下面是增加的代码
  public $js = [
    'js/bootstrap.js',
  ];
}
