这是我一直在使用的代码，执行该代码时会出现此错误：
** SCRIPT5022：无法从../../resources/null/App.js加载“ null / App.js”：404-未找到
HTTP404：未找到-服务器未找到与请求的URI（统一资源标识符）匹配的任何内容。 （XHR）GET-https://webidetesting4688865-p2000413989trial.dispatcher.hanatrial.ondemand.com/resources/null/App.js **
我得到黑屏
您能告诉我代码有什么问题吗？

从表上的绑定中删除products>，因为setModel也不为模型使用名称。
然后它应该可以工作。 （假设网址正确，并且json文件格式正确）
如果您在onInit中创建模型，则无需在清单中使用它。一旦运行，您应该在清单中定义它，而不是在onInit
