點選.trash_can鈕隱藏選取的li標籤

Answer 1

建一個空數組 用來存放你需要刪除資料的index 例如delProds

在你的checkbox上加上ng-click
觸發時判斷為true的時候就把這個產品的index push到delProds數組
為false的時候從delProds裡面刪除

然後在點擊刪除按鈕的時候把對應序號的資料都刪除掉就可以了

Answer 2

用splice(),例如products_mes.splice(下標,1) 可以刪除陣列的某一項

Answer 4

var index = products_mes.indexOf(data);
products_mes.splice(index,1);
data：為選取的那個物件
