Knockout返回一些奇怪的代码而不是我的字符串

Question

    `self.affiliateDescription = ko.observable();

    self.connectedTo = ko.computed(function() {
      return self.app.translate.get("connectedTo") + ": " + self.affiliateDescription;
    });

I assigned affiliateDescription here:
getDataPromise()
      .then(function(result) {
        console.log(result);
       //fetches data from an API and returns a JSON string
              var description = result[0].Description;
              self.affiliateDescription = JSON.stringify(description);
              console.log(self.affiliateDescription); //string prints fine here.
        }
      });`
`

当我去更新affiliateDescription时，我在控制台中打印它并获取我想要的字符串，但connectedTo计算字符串是＆＃34;连接到：然后self.affiliateDescription＆＃34;给了我一堆垃圾无意义代码？

它将这个垃圾放在我的字符串应该在网页上： function observable（）{if（arguments.length＆gt; 0）{//写入//如果值没有改变则忽略写入if（observable.isDifferent（observable [observableLatestValue]，arguments [0]））{observable .valueWillMutate（）; observable [observableLatestValue] = arguments [0]; observable.valueHasMutated（）;返回这个; //允许链式赋值} else {//读取ko.dependencyDetection.registerDependency（observable）; //如果调用者执行了＆＃34;读取＆＃34; operation return observable [observableLatestValue]; }}
