Ajax also redirects when enableLanguagePersistence is turned on

Ajax also redirects when enableLanguagePersistence is turned on,Can I add a judgment or configuration item without redirecting when ajax requests?

` if (
// Only add language if it's not empty and ...
$language!=='' && (

                // ... it's not the default language or default language uses URL code ...
                !$isDefaultLanguage || $this->enableDefaultLanguageUrlCode ||

                // ... or if a language is explicitely given, but only if
                // either persistence or detection is enabled.  This way a
                // "reset URL" can be created for the default language.
                $isLanguageGiven && ($this->enableLanguagePersistence || $this->enableLanguageDetection)
            ) && !Yii::$app->request->isAjax
        ) {
            $key = array_search($language, $this->languages);
            if (is_string($key)) {
                $language = $key;
            }
            if (!$this->keepUppercaseLanguageCode) {
                $language = strtolower($language);
            }

            // Calculate the position where the language code has to be inserted
            // depending on the showScriptName and baseUrl configuration:
            //

This could only happen if you send AJAX requests without the correct language in the URL. This should never be the case. You should create the AJAX URLs from Yii, e.g. with Url::to(), then they will contain the correct language code.

Well, this is currently done, just feel that the ajax request does not need to be redirected.
