Angular Radio按鈕單擊顯示和隱藏不起作用

Question

我是Angular的初學者，當我單擊單選按鈕顯示和隱藏div區域時，嘗試創建Angular 5。 ，當我單擊customer-2 單選按鈕時，我創建了customer-1和customer-2 單選按鈕 （它顯示為1st div），那是正常的html可以正常工作，但是對於angular 5卻不起作用，有人知道如何正確地把那個放在Angular5中？

謝謝

做到這一點的Angular方法是將代碼放在app.component.ts中，而不是在帶有jquery選擇器的腳本標簽中。

您的類中應該有兩個成員變量，它們由component.ts-fil中的方法更改，並通過使用HTML中的（單擊）綁定到該方法。 要綁定到代碼中的變量，請使用[attr]語法。
