如何不用registerJs直接在view里写js [ 2.0 版本 ]

想加载在头部，给你个例子，注意$jsOptions

class AppAsset extends AssetBundle
{
    public $basePath = '@webroot';
    public $baseUrl = '@web';
    public $css = [
        'css/site.css',
    ];
    public $js = [
    ];
    public $depends = [
        'yii\web\YiiAsset',
        'yii\bootstrap\BootstrapAsset',
        '\rmrevin\yii\fontawesome\AssetBundle',
    ];
    public $jsOptions = [
        'position' => \yii\web\View::POS_HEAD
    ];    
}
