你知道Deferred和递归次数限制吗？下面有个不错的实例，大家可以看看
rush:js;">
function runAsyncTTS(text,speecher,audiopath) {
var def = jQuery.Deferred();
var args = {"SynthText": text,"VoiceSpeecher": speecher,"WordSpeed": "3","UseCSSML": "0","AudioPath": audiopath};
tts.asyncTTS(JSON.stringify(args),function(err,result) {
def.resolve(result);
});
return def.promise();
}
rush:js;">
function textToSpeechBat(MetaJson,audioPath) {
var def = $.Deferred();
var result = {originalWords:"",resultJsonArr:[]};
var jsons="";
for(var index=0;index < MetaJson.words.length;index++) {
