Angular Js - TypeError：對象不支持屬性或方法「包含」

Question

我在我的應用程序中使用角度js。當我在IE瀏覽器上運行我的應用程序時，它顯示以下錯誤。

TypeError: Object doesn't support property or method 'includes' 
at request (https://xxx.xx.xxx.com/js/app.js:32:20185) 
at u (https://xxx.xx.xxx.com/js/base.js:5:30028)

at s (https://xxxx.xx.xxxx.com/js/base.js:4:7480) 
at ae (https://xxxx.xx.xxxx.com/js/base.js:4:7676) 

我該如何解決這個問題？

謝謝

包括（）在Internet Explorer上不受支持。最簡單的選擇是使用indexOf，像這樣：

if(your_string.indexOf("?") >= 0) { 
    //statements 
}
