javascript - angularjs 想寫一個簡單的toast，如何實作？
思路是使用directive來實現，但卡在不知道怎麼暴露API給controller
我想彈出toast的時候在controller裡調用API xxx.showToast,但不知道怎麼才能取到這個接口，directive也不能作為依賴注入，卡在這裡了，望指教。

你directive接過去寫就可以直接使用了
.toast-box{
position:absolute;
top:45%;
z-index:99;
max-height:250px;
overflow-y:auto;
margin:0 auto;
float:left;
left:50px;
right:50px;
text-align:center;}
.toast-top{
top:0;}
.toast-bottom{
top:auto;
bottom:0;}
.toast-box .toast-item{
display:inline-block;
margin-top:5px;
padding:0 20px;
