JAVA美國數字格式

NumberFormat usFormat = NumberFormat.getIntegerInstance(Locale.US);
//使用美國格式
String number = usFormat.format(1000)
//將1000轉為美國格式
System.out.println(number);
//結果1,000

URLConnection應用,與遠端做資料溝通

//傳送物件到遠端
    URL url = new URL("遠端網址");
    URLConnection urlConnection = url.openConnection();
    urlConnection.setDoOutput(true);
    urlConnection.setDoInput(true);
    urlConnection.setUseCaches(false);
    urlConnection.setDefaultUseCaches(false);
    urlConnection.setRequestProperty("Content-Type", "application/x-java-serialized-object");

    ObjectOutputStream ous = new ObjectOutputStream(urlConnection.getOutputStream());      
    ous.writeObject(cgsNums);
    ous.writeObject(qcOrders);
    ous.writeObject(cpdtOwner);
    ous.flush();
    ous.close();

//遠端將資料組合後
//讀取網頁
 StringBuffer html = new StringBuffer();
 BufferedReader br = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
    String inputLine;
    while ((inputLine = br.readLine()) != null) {
        html.append(inputLine).append("\r\n");
    }

JQuery checkbox 應用

每次都忘記JQuery對checkbox操作的寫法,下定決心把他寫起來 

取得已勾選的數量
$('input[type=checkbox][name=cpdtNum]:checked').length

檢查checkbox使否已被勾選
$(obj).is(':checked')
