YUI2.8 实现datatable从server端动态获取数据，并实现分页功能(下)

7 编写JSP页面的HTML和JS代码，路径和文件名 /yuiapp/WebRoot/pages/datatable/datatable01.jsp

具体的内容是

<%@ page language="java" contentType="text/html; charset=utf-8" pageEncoding="utf-8"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";
%>
<%String sysPath =basePath+"appjs/yuijs/build"; %>
<html>
<head>
<meta http-equiv="content-type" content="text/html; charset=utf-8">
<title>datatable_01</title>
<style type="text/css">
/*margin and padding on body element
can introduce errors in determining
element position and are not recommended;
we turn them off as a foundation for YUI
CSS treatments. */
body {
margin:0;
padding:0;
}
</style>

<style type="text/css">
/* custom styles for this example */
.yui-skin-sam .yui-dt-liner { white-space:nowrap; }
</style>

</head>
<body class="yui-skin-sam">
<div class="exampleIntro">
<p>datatable_01 practice</p>
</div>
<div id="dynamicdata"></div>
<script type="text/javascript">
YAHOO.namespace("datatable_01");
YAHOO.datatable_01.DynamicData = function() {
    // Column definitions
    var myColumnDefs = [
            {key:"id"},
            {key:"quantity"},
            {key:"amount"},
            {key:"title"}
    ];
    //var myDataSource = new YAHOO.util.DataSource("/yuitab/do_getInstList.action?name=test&pageSize=10&");
    var myDataSource = new YAHOO.util.DataSource("/yuitab/do_getBookList.action?");
    myDataSource.responseType = YAHOO.util.DataSource.TYPE_JSON;
    myDataSource.responseSchema = {
        resultsList: "records",
        fields: [
            {key:"id"},
            {key:"quantity"},
            {key:"amount"},
            {key:"title"}
        ],
        metaFields: {
            totalRecords: "totalRecords" // Access to value in the server response
        }
    };

    // DataTable configuration
    var myConfigs = {
        initialRequest: "pageSize=10&sort=id&dir=asc&startIndex=0",//"sort=ptInsId&dir=asc&startIndex=0", // Initial request for first page of data
        dynamicData: true, // Enables dynamic server-driven data
        sortedBy : {key:"id", dir:YAHOO.widget.DataTable.CLASS_ASC}, // Sets UI initial sort arrow
        paginator: new YAHOO.widget.Paginator(
                {   rowsPerPage:10,
                 firstPageLinkLabel : "首页",
                 lastPageLinkLabel : "末页",
                 previousPageLinkLabel:"上页",
                 nextPageLinkLabel:"下页"
            }) // Enables pagination
    };

    // DataTable instance
    var myDataTable = new YAHOO.widget.DataTable("dynamicdata", myColumnDefs, myDataSource, myConfigs);
    // Update totalRecords on the fly with value from server
    myDataTable.handleDataReturnPayload = function(oRequest, oResponse, oPayload) {
        oPayload.totalRecords = oResponse.meta.totalRecords;
        return oPayload;
    }
    return {
        ds: myDataSource,
        dt: myDataTable
    };
}();
</script>

</body>
</html>

8、重新部署应用，启动tomcat进行测试，具体结果见附件的截图

从tomcat打印的信息看，当点击了前台页面的未被点击过的链接时，会打印出我所设置的调试信息，当重新点击时，则不会打印信息，就说明YUI会解析所接收到的请求，如果是相同的请求，则不转到服务器端来了。打印信息如下：

2010-5-14 7:37:39 com.opensymphony.xwork2.validator.ActionValidatorManagerFactory <clinit>
信息: Detected AnnotationActionValidatorManager, initializing it...
getBookList is called....startIndex=0
getBookList is called....startIndex=10
getBookList is called....startIndex=0

上班时间到了，我要去坐公交车了。

我也刚刚学习YUI，希望有看到这篇文章的朋友有问题和我交流，我的QQ是604320137 手机号码是133 9175 8739

请注明是javaeye yui的即可。

附件我把yui和jar没有包含进来，望谅解。
