Javascript 角度超前异步结果-接收错误“;TypeError:无法使用';在';要搜索的运算符。。。在……中”;
我已经为一个有角度的UI typeahead字段做了一个指令。我正在尝试设计它,以便当用户键入时,它发送异步后端调用以获取结果,这些结果将填充出现的下拉列表,如中所示。但是,当我开始键入时(在本例中为“a”),会出现以下错误:Javascript 角度超前异步结果-接收错误“;TypeError:无法使用';在';要搜索的运算符。。。在……中”;,javascript,angularjs,asynchronous,angular-ui-bootstrap,angular-ui-typeahead,Javascript,Angularjs,Asynchronous,Angular Ui Bootstrap,Angular Ui Typeahead,我已经为一个有角度的UI typeahead字段做了一个指令。我正在尝试设计它,以便当用户键入时,它发送异步后端调用以获取结果,这些结果将填充出现的下拉列表,如中所示。但是,当我开始键入时(在本例中为“a”),会出现以下错误: TypeError: Cannot use 'in' operator to search for 'getters' in a 下面是进行REST调用的工厂方法: certFactory.getUsersWithMatchingUsername = function(
