问题
Same as title, i don't want using bootstrap.css and bootstrap.js. I try using:
'assetManager' => [
    'bundles' => [
        'yii\bootstrap\BootstrapAsset' => [
            'css' => [],
        ],
    ],
],
It remove bootstrap.css but can't remove bootstrap.js. Somebody can help me?
回答1:
In web.php config file add the following code into components array:
'assetManager' => [
        'bundles' => [
            'yii\bootstrap\BootstrapPluginAsset' => [
                'js'=>[]
            ],
        ],
    ],
To be more comprehensive:
in order to disable Css (bootstrap.css):
'assetManager' => [
    'bundles' => [
        'yii\bootstrap\BootstrapAsset' => [
            'css' => [],
        ],
    ],
],
in order to disable JS (bootstrap.js):
'assetManager' => [
    'bundles' => [
        'yii\bootstrap\BootstrapPluginAsset' => [
            'js'=>[]
        ],
    ],
],
in order to disable JQuery (jquery.js)
'assetManager' => [
    'bundles' => [
        'yii\web\JqueryAsset' => [
            'js'=>[]
        ],
    ],
],
In order to have all of them disabled:
'assetManager' => [
    'bundles' => [
        'yii\web\JqueryAsset' => [
            'js'=>[]
        ],
        'yii\bootstrap\BootstrapPluginAsset' => [
            'js'=>[]
        ],
        'yii\bootstrap\BootstrapAsset' => [
            'css' => [],
        ],
    ],
],
UPDATE
As Soju mentioned in comments, another alternative way would be disabling these files in AppAsset class, which is located in ./assets/, then remove the following lines:
public $depends = [
   'yii\web\YiiAsset',              #REMOVE
   'yii\bootstrap\BootstrapAsset',  #REMOVE
];

For anyone that gets "Invalid Call" errors you have to add Ali's answer to 'components' in $config variable in app/config/web.php E.g.
'components' => [
    'assetManager' => [
        'bundles' => [
            'yii\web\JqueryAsset' => [
                'js'=>[]
            ],
            'yii\bootstrap\BootstrapPluginAsset' => [
                'js'=>[]
            ],
            'yii\bootstrap\BootstrapAsset' => [
                'css' => []
            ]
        ]
    ],
    ...
],

On AppAsset.php file add this:
public function init()
{
    parent::init();
    // resetting BootstrapAsset to not load own css files
    \Yii::$app->assetManager->bundles['yii\\bootstrap\\BootstrapAsset'] = [
        'css' => [],
        'js' => []
    ];
}
