如何在React Native中记录window.API.cmi中的scorm交互

Question

我有 SCORM 文件并使用包 react-native-webview 打开它。我需要跟踪进度，但是当我注入 javascript 来设置变量时，catch 部分执行并且警报显示 TypeError: undefined is not an object (evaluating 'window.API.cmi)

const injectTrack = () => {
const setTrackInjection = `
    try {
        window.API.cmi.core.student_id = "${user?.id ? user?.id : ''}";  
        window.API.cmi.core.student_name = "${user?.firstname ? user?.firstname : ''}";
        window.API.cmi.suspend_data = '${suspend_data}';
        window.API.cmi.core.total_time = '${total_time}';
        window.API.cmi.core.session_time = '${session_time}';
        window.API.cmi.core.score.raw = '${scoreRaw}';
        window.API.cmi.core.score.max = '${scoreMax}';
        window.API.cmi.core.score.min = '${scoreMin}';
        window.API.cmi.core.lesson_status = '${lesson_status}';
        window.API.cmi.core.exit = '${exit}';
        
    } catch(error){
        alert(error);
    }
    true;`;

webviewRef.current.injectJavaScript(setTrackInjection);

};
