利用JQUERY Autocomplete 插件实现自动提示输入

Fri, 25 Mar 2011 10:39:17 +0800

下载地址： http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/

要在页面引用如下js库和样式表

jquery.ajaxQueue.js
jquery.autocomplete.css
jquery.autocomplete.js
jquery.bgiframe.min.js
jquery.js
thickbox-compressed.js
thickbox.css

例如

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN" "http://www.w3.org/TR/html4/strict.dtd">
<html>
<head>

<title>jQuery Autocomplete Plugin</title>
<script type="text/javascript" src="jquery/jquery.js"></script>
<script type='text/javascript' src='jquery/jquery.bgiframe.min.js'></script>
<script type='text/javascript' src='jquery/jquery.ajaxQueue.js'></script>
<script type='text/javascript' src='jquery/thickbox-compressed.js'></script>
<script type='text/javascript' src='jquery/jquery.autocomplete.js'></script>

<link rel="stylesheet" type="text/css" href="jquery/jquery.autocomplete.css" />
<link rel="stylesheet" type="text/css" href="jquery/thickbox.css" />
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<script type="text/javascript">
$().ready(function() {
    $("#singleBirdRemote").autocomplete("search.jsp", {
        width: 260,
        selectFirst: true,
        extraParams:{EP1:'一',EP2:'二'}
    });

});
</script>

</head>
<body>
    <form autocomplete="off">
            <label>Single Bird (remote):</label>
            <input type="text" id="singleBirdRemote" />
    </form>
   </body>
</html>

一个简单的返回结果的jsp文件

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ page import="java.io.*" %>
<%@ page import="java.util.*" %>
<%@ page import="java.text.*" %>
<%@ page import="java.sql.*" %>
<%@ page import="javax.sql.*" %>
<%@ page import="javax.naming.*" %>
<%
request.setCharacterEncoding("UTF-8");
for (Enumeration names = request.getParameterNames();names.hasMoreElements();) {
    String name = (String)names.nextElement();
    String value = request.getParameter(name);
    System.out.println(name+":"+value);
}
%>
aaa
bbb
ccc

中国人民解放军

提示：autocomplete会自动将输入框的数据发送到指定的url地址，参数名称为q。

如果需要附加其它参数，可以使用 extraParams 来指定。

要使用UTF-8编码，否则中文会出现乱码。

Apache Click Table 行号的添加

Sat, 12 Mar 2011 18:29:03 +0800

        Column myColumn = new Column("sn", "序号"){
           protected void renderTableDataContent(Object row, HtmlStringBuffer buffer,Context context, int rowIndex) {
               String sn = Integer.toString(rowIndex);
               buffer.append(sn);
           }
       };
        customerTable.addColumn(myColumn);

重写Column的 renderTableDataContent 方法。

Apache Click Table 行背景颜色的改变

Sat, 12 Mar 2011 18:27:08 +0800

    @Bindable protected Table customerTable = new Table("customerTable"){
       public void addRowAttributes(Map attributes, Object row, int rowIndex) {
           Customer customer = (Customer) row; //取得对象，可根据对象的属性进行相关操作。

          attributes.put("style", "background-color:red;");
           }
   };

需要重写 addRowAttributes 方法，设置行的style的背景色。

EL 表达式的隐含变量

Sun, 27 Feb 2011 10:10:25 +0800

The JSP expression language defines a set of implicit objects:

pageContext: The context for the JSP page. Provides access to various objects including:
   servletContext: The context for the JSP page’s servlet and any web components contained in the same application. See Accessing the Web Context.
   session: The session object for the client. See Maintaining Client State.
   request: The request triggering the execution of the JSP page. See Getting Information from Requests.
   response: The response returned by the JSP page. See Constructing Responses.

In addition, several implicit objects are available that allow easy access to the following objects:
   param: Maps a request parameter name to a single value
   paramValues: Maps a request parameter name to an array of values
   header: Maps a request header name to a single value
   headerValues: Maps a request header name to an array of values
   cookie: Maps a cookie name to a single cookie
   initParam: Maps a context initialization parameter name to a single value

Finally, there are objects that allow access to the various scoped variables described in Using Scope Objects.
   pageScope: Maps page-scoped variable names to their values
   requestScope: Maps request-scoped variable names to their values
   sessionScope: Maps session-scoped variable names to their values
   applicationScope: Maps application-scoped variable names to their values

利用Ghost克隆，发现不行。查了一下，使用dd命令，就可以。Linux的工具真是丰富！

Oracle ResultSet.TYPE_SCROLL_INSENSITIVE 乱码

Mon, 6 Dec 2010 22:06:30 +0800

Oracle 库，列编码是iso-8859-1,存储的是中文。

使用 new String(rs.getString(1).getBytes("iso-8859-1"),"gb2312")

stmt = conn.createStatement() 正常

stmt = conn.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE ,ResultSet.CONCUR_READ_ONLY ) 还是乱码

原因，暂时没有查出。
