Lập trình NET SQL Jquery Ajax: Java

27. Lấy danh sách Job
       List<String> listRegistrant = new ArrayList<String>();
       for(Map<String, Object> obj : t_ConferenceDao.getRegistrant("")){
           listRegistrant.add(String.valueOf(obj.get("input_user_name")));
       }
       mainForm.setlistRegistrant(listRegistrant);

26. Xuất ra Output display system.out.println("asf");

25. Form - Controller - EditService - Dao - Hit - SQL

20. Tùy hứng argment

// 対象のボタンタグを取得

var target = $('#funcBtnCommon').find('#' + targetBtn);

19. Gán tham chiếu và lấy giá trị mảng

       $("#dispItemMultiSelectInspection").change(function() {

       // リクエストパラメータを定義       -   Define the request parameters
        var postData = {};

15. Hàm gọi hàm function call function
function setCustomerInspSelectEvent(){

$("#dispItemMultiSelectInspection").unbind('change');

       $("#dispItemMultiSelectInspection").change(function() {

       // リクエストパラメータを定義
        var postData = {};

13. Khai báo mảng…

List<String> addressInputDateTimeList = new ArrayList<String>();

Date date = DateTimeToString.toDate(dateTime, "format của chuỗi dateTime")

String date = DateTimeToString.convert(dateTime, "format mong muốn");

12. <select class="w185 searchPersonByCd searchPersonByNameKana openSearchPersonDlg" data-dlg-param="site_cd">

<c:forEach items="${siteList}"

var="item" varStatus="status">

<c:if test="${item.site_cd == mainForm.site_cd}">

<option value="<c:out value="${item.site_cd}"/>" selected><c:out value="${item.site_name}"/></option>

</c:if>

<c:if test="${item.site_cd != mainForm.site_cd}">

</c:if>

</c:forEach>

</select>

obj3.parent().parent().find('.colorChange').removeClass("changeColorWhite").addClass("changeColerpink");

10. Include
<% @ include file="/common/header.jsp" %>
9. Ví dụ tiếp theo
sau khi biến được truyền từ A.jsp, tại B.jsp ta code:
<%= request.getParameter("name") %>
thay bằng ${param.name}
hoặc thay bằng thay bằng ${param[name]}

8. Express Language
sample.jsp
1. Đọc giá từ file XML, biến servlet
<body>
This is a sample.</br>
This is Blog <%= config.getInitParameter("blog") %>
<% out.println("Vietnam"); %>

2. Đọc giá trị global
Image name:
<%= ((Image) request.getAttribute("imageName")).getName() %>
<% pageContext.setAttribute("scope", "Page Context"); %>
page of the: <%= pageContext.getAttribute("scope") %>
Đây nè trym: ${pageScope.scope }
Nè nữa trym: ${requestScope.student.name}

<%=pageContext.findAttribute ("otherScope") %>

Đọc biến toàn cục trong web.xml: <%= application.getInitParameter("account") %> hoặc
${initParam.account}

Đây nữa nè trym: ${ 4 + 5 }
.

7. Getter setter

6. Cookie

Cookie cookie new Cookie("location", "Vietnam");
response.addCookie(cookie);

for (Cookie c: request.getCookies()){
        System.out.println(c.getName());
        System.out.println(c.getValue());

}

.

5. session
Clear session
session.invalidate();

Đặt hạn thời gian session
<session-config>
         <session-timeout>15</session-timeout>
</session-config>

session.setMaxInactiveInterval(900);

HttpSession session = request.getSession();
session.setAttribute("username", username);

HttpSession session = request.getSession();
String username = (String) session.getAttribute("username");

ServletContext context = this.getServletContext();
String account = context.getInitParameter("song");

3.Servlet Initialization Parameter

ServletConfig config = this.getServletConfig();
//Hoặc this.getServletConfig().getServletContext();

String song = config.getInitParameter("song");

PrintWriter writer = response.getWriter();
writer.println("Username or Password is incorrect...!!!");

2.
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        // TODO Auto-generated method stub
        String username = request.getParameter("username");
        String password = request.getParameter("password");

        PrintWriter writer = response.getWriter();
        DatabaseManagement dm = new DatabaseManagement();

        if(dm.checkUser(username, password)){
            writer.println("Welcome " + username + " o VN");
        }
        else{
