Javascript 如何将数组数据从java发送到jsp，并在jsp中将数据设置为变量？,javascript,java,arrays,jsp,parameter-passing,Javascript,Java,Arrays,Jsp,Parameter Passing,这是JAVA public class Dest_id extends HttpServlet { @Override protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException { String destination = request.getParameter("destination"); String

这是JAVA

public class Dest_id extends HttpServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response)throws ServletException, IOException {
    String destination = request.getParameter("destination");
    String product = request.getParameter("product");
    String currency = request.getParameter("currency");
    String destQuery = "DESTINATION LIKE '" + destination + "%'";
    String prodQuery = "PRODUCT = '" + product + "'";
    String currQuery = "MOST_INFL_CURRENCY = '" + currency + "'";
    if (destination != null)
        destination = destination.toUpperCase();
    ResultSet rs;
    int bil = 1;
    String destID[] = null;

    try {
        Class.forName("com.mysql.jdbc.Driver");
        Connection con = DriverManager.getConnection("jdbc:mysql://localhost:3306/bababa","root","");
        Statement stmt = con.createStatement();
        rs = stmt.executeQuery("select * from icx_pricing_desk where " + destQuery.toUpperCase() + " AND " + currQuery + " AND " + prodQuery);
        while (rs.next()) {
            System.out.println(bil + "|" + rs.getString("DESTINATION") + "|" + rs.getString("PRODUCT") + "|" + rs.getString("MOST_INFL_CURRENCY"));

            destID[bil] = rs.getString("DEST_ID");
            bil++;
        }

        con.close();
    } catch(Exception e) { System.out.println(e); } 
response.setContentType("text/html;charset=UTF-8");
PrintWriter out = response.getWriter();

out.println(destID);
}
}

这是我的JSP页面

嗯。。。大多是这样。但是如果您有更好的想法，请帮助。

我想实际上它是以字符串的形式出现的，请尝试使用JSON并将响应设置为JSON，或者在JAVASCRIPT中通过JSON.parse（“yourResponseData”）将其转换为JSON；实际上，我想它是以字符串的形式出现的，试着使用JSON并将响应设置为JSON，或者在JAVASCRIPT中通过JSON.parse（“yourResponseData”）转换它；
