Yii2如何向腳本標簽添加參數

Question

獲得渲染的JS資產看起來像這樣：

<script src="/assets/a00ccd3f/jquery.min.js"></script>

我需要添加async="async"標記。

所以應該看起來像

<script src="/assets/a00ccd3f/jquery.min.js" async="async" ></script>

我怎樣才能做到這一點？

Answer 1

您可以在自己的AssetBundle中添加

public $jsOptions = [
    'async' => 'async',
];

如果要將其添加到Yii2 JqueryAsset捆綁包（或其他捆綁包）中，可以將其添加到配置的組件部分：

'assetManager' => [
    'bundles' => [
        'yii\web\JqueryAsset' => [
            'jsOptions' => [
                'async' => 'async'
            ],
        ],
    ],
],

Answer 2

像這樣

<?php
/**

* @copyright Copyright (c) 2008 Yii Software LLC
* @license http://www.yiiframework.com/license/
*/
namespace frontend\assets;
use yii\web\AssetBundle;
class ThemeCustomAsset extends AssetBundle
{
public $basePath    = '@webroot';
public $baseUrl     = '@web';
public $css = [];
public $js = [
    "js/lazysizes.min.js"
];
public $depends = [
    #'yii\web\YiiAsset',
    #'yii\bootstrap\BootstrapAsset',
];
public $jsOptions = ['async' => 'async'];
}
