我想在ServiceNow服務門戶中實現Table分頁。我找不到從客戶端腳本實現第二個控制器的方法。它會拋出錯誤「未捕獲的錯誤：未知的提供者：來自ngAria的$ compileProvider」。這裏是小部件在ServiceNow服務門戶中實現第二個控制器

讓我試試。你能解釋一下嗎？ – John
當然。如果你到了控制檯，你可以看到下面的代碼 api.controller = function（） { \t var c = this; \t c.getData = function（） \t { //您的代碼 \t}; \t c.getData（）; } ServiceNow將小部件客戶端腳本轉換爲控制器。 'c'只不過是'這個'。我的答案中提到了注入依賴關係的唯一方法。 我會參考https://github.com/service-portal/documentation/blob/master/documentation/widget_client_script.md瞭解更多信息。 – 2017-04-24 18:44:53
謝謝。有效。 – John
