Cordova TTS无法读取未定义的属性“ then”

Question

有一个带Uncaught TypeError的TTS调用：无法读取未定义的属性'then'。 我了解我应该使用退货，但我不知道该如何操作或应该退货

 function successCallback(key) { hconsole.log('Story for ' + key + ' completed. Adding ' + playing.getItem(key).ctv + ' to past'); past.addItem(key, playing.getItem(key)); qpast.addItem(key, playing.getItem(key)); playing.removeItem(key); $('#now-playing').html('<div class="grip"></div>Waiting for next story ...'); window.plugins.statusBarNotification.notify("Historigin", "Waiting for next story ...", Flag.FLAG_NO_CLEAR); } function failureCallback(error) { alert(reason); hconsole.log('Unable to play story: ' + JSON.stringify(error)); hconsole.log('DUDE: ' + playing.getItem(key).ctv + ' ' + playing.getItem(key).state + '...' + playing.getItem(key).story); queued.addItem(key, playing.getItem(key)); qpast.removeItem(key); past.removeItem(key); playing.removeItem(key); } if (TTS_ENABLED) { hconsole.log('TTS is ENABLED'); document.addEventListener('deviceready', function () { hconsole.log("WERE SPEAKING"); window.TTS.speak(playing.getItem(key).ctv + ' ' + playing.getItem(key).state + ' ' + playing.getItem(key).story).then(successCallback, failureCallback); }, false); } else { blah blah blah... } 

Answer 1

尝试使用此方法

...
if (TTS_ENABLED) {
    hconsole.log('TTS is ENABLED');
    document.addEventListener('deviceready', function () {
        hconsole.log("WERE SPEAKING");
        window.TTS.speak(playing.getItem(key).ctv + ' ' +       playing.getItem(key).state + ' ' + playing.getItem(key).story).then(successCallback, failureCallback).catch(failureCallback);
    }, false);
} else {
    blah blah blah...
}
...

还要确保将TTS连接到窗口
