示例

以下示例使用了 Exit For。如果計數器值達到 4，則退出 For 迴圈，控制權會立即跳至 For 迴圈之後的下一條語句。

<!DOCTYPE html>
<html>
   <body>
      <script language = "vbscript" type = "text/vbscript">
         Dim a : a = 10
         For i = 0 to a Step 2 'i is the counter variable and it is incremented by 2
            document.write("The value is i is : " & i)
            document.write("<br></br>")
         
         If i = 4 Then
            i = i*10  'This is executed only if i = 4
            document.write("The value is i is : " & i)
            Exit For 'Exited when i = 4
         End If	 
         Next
         
      </script>
   </body>
</html>

當執行以上程式碼時，它會在控制檯列印以下輸出。

The value is i is : 0

The value is i is : 2

The value is i is : 4

The value is i is : 40
