jqgrid学习(二)读取XML数据

通过读取服务端的XML来构造grid，页面展现文件如下jqgrid-demo-xml.html
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>My First Grid</title>

<link rel="stylesheet" type="text/css" media="screen"
href="../components/jqgrid/css/ui-lightness/jquery-ui-1.7.2.custom.css" />
<link rel="stylesheet" type="text/css" media="screen"
href="../components/jqgrid/css/ui.jqgrid.css" />
<style>
html, body {
margin: 0;
padding: 0;
font-size: 75%;
}
</style>

<script src="../components/jquery/jquery-1.3.2.min.js" type="text/javascript"></script>
<script src="../components/jqgrid/js/i18n/grid.locale-en.js" type="text/javascript"></script>
<script src="../components/jqgrid/js/src/grid.loader.js" type="text/javascript"></script>

<script type="text/javascript">
// Here we set a globally the altRows option
jQuery.extend(jQuery.jgrid.defaults, { altRows:true });
</script>

<script>
jQuery(document).ready(function(){
jQuery("#list").jqGrid({
url:'jqgrid-demo-xml-data.jsp',
datatype: 'xml',
mtype: 'POST',
altRows: false,
colNames:['Inv No','Date', 'Amount','Tax','Total','Notes'],
colModel :[
{name:'invid', index:'invid', width:55},
{name:'invdate', index:'invdate', width:90},
{name:'amount', index:'amount', width:80, align:'right'},
{name:'tax', index:'tax', width:80, align:'right'},
{name:'total', index:'total', width:80, align:'right'},
{name:'note', index:'note', width:150, sortable:false}
],
xmlReader: {
root: "rows",
row: "row",
page: "rows>page",
total: "rows>total",
records : "rows>records",
repeatitems: true,
cell: "cell",
id: "[id]",
userdata: "userdata"
},
pager: '#pager',
rowNum:10,
rowList:[10,20,30],
sortname: 'invid',
sortorder: 'desc',
viewrecords: true,
caption: 'My first grid'
});

alert(jQuery("#list").getGridParam('userData'));
alert(jQuery("#list").getUserData() + ":" + jQuery("#list").getUserDataItem( "tax" ));
});

</script>
</head>
<body>
<table id="list"></table>
<div id="pager"></div>
</body>
</html>

提供XML的SERVER端代码，我写了个简单的JSP来当做DEMO，jqgrid-demo-xml-data.jsp如下：

<%@page contentType="text/xml;charset=UTF-8"%>

<rows>
<page>1</page>
<total>2</total>
<userdata name="totalinvoice">240.00</userdata>
<userdata name="tax">40.00</userdata>
<records>2</records>
<row id='1'>
<cell>data1</cell>
<cell>data2</cell>
<cell>data3</cell>
<cell>data4</cell>
<cell>data5</cell>
<cell>data6</cell>
</row>
<row id='2'>
<cell>data1</cell>
<cell>data2</cell>
<cell>data3</cell>
<cell>data4</cell>
<cell>data5</cell>
<cell>data6</cell>
</row>
</rows>
