使用datagrid详细视图,用户可以展开一行去显示一个附加的详细信息,任何类容可以加载作为行详细,subgrid(子datagrid)也可以动态加载.这个教程将向你展示如何创建一个子grid在主grid上.

步骤 1: 创建主要的 DataGrid
[html]
<table id="dg" style="width:700px;height:250px" url="datagrid22_getdata.php" title="DataGrid - SubGrid" singleselect="true" fitcolumns="true">
    <thead>
        <tr>
            <th field="itemid" width="80">Item ID</th>
            <th field="productid" width="100">Product ID</th>
            <th field="listprice" align="right" width="80">List Price</th>
            <th field="unitcost" align="right" width="80">Unit Cost</th>
            <th field="attr1" width="220">Attribute</th>
            <th field="status" width="60" align="center">Status</th>
        </tr>
    </thead>
</table>

<table id="dg" style="width:700px;height:250px" url="datagrid22_getdata.php" title="DataGrid - SubGrid" singleselect="true" fitcolumns="true">
    <thead>
        <tr>
            <th field="itemid" width="80">Item ID</th>
            <th field="productid" width="100">Product ID</th>
            <th field="listprice" align="right" width="80">List Price</th>
            <th field="unitcost" align="right" width="80">Unit Cost</th>
            <th field="attr1" width="220">Attribute</th>
            <th field="status" width="60" align="center">Status</th>
        </tr>
    </thead>
</table> 步骤 2: 设置详细视图显示子grid
使用详细视图,切记引入view script js文件在你的页面的头部.

[html]
<script type="text/javascript" src="http://www.jeasyui.com/easyui/datagrid-detailview.js"></script>

$('#dg').datagrid({
    view: detailview,
    detailFormatter:function(index,row){
        return '<div style="padding:2px"><table id="ddv-' + index + '"></table></div>';
    },
    onExpandRow: function(index,row){
        $('#ddv-'+index).datagrid({
            url:'datagrid22_getdetail.php?itemid='+row.itemid,
            fitColumns:true,
            singleSelect:true,
            rownumbers:true,
            loadMsg:'',
            height:'auto',
            columns:[[
                {field:'orderid',title:'Order ID',width:100},
                {field:'quantity',title:'Quantity',width:100},
                {field:'unitprice',title:'Unit Price',width:100}
            ]],
            onResize:function(){
                $('#dg').datagrid('fixDetailRowHeight',index);
            },
            onLoadSuccess:function(){
                setTimeout(function(){
                    $('#dg').datagrid('fixDetailRowHeight',index);
                },0);
            }
        });
        $('#dg').datagrid('fixDetailRowHeight',index);
    }
}); 当用户点击展开按钮('+'),onExpandRow事件将被触发,我们创建一个新的子grid和3列,记得调用fixDetailRowHeight方法对主grid,当子grid数据加载成功

之后改变大小.

步骤 3: 服务器端代码
datagrid22_getdata.php

[php]
$result = array();

include 'conn.php';

$rs = mysql_query("select * from item where itemid in (select itemid from lineitem)");

$items = array();
while($row = mysql_fetch_object($rs)){
    array_push($items, $row);
}

echo json_encode($items);

$result = array();

include 'conn.php';

$rs = mysql_query("select * from item where itemid in (select itemid from lineitem)");

$items = array();
while($row = mysql_fetch_object($rs)){
array_push($items, $row);
}

echo json_encode($items); datagrid22_getdetail.php

[php]
$itemid = $_REQUEST['itemid'];

include 'conn.php';

$rs = mysql_query("select * from lineitem where itemid='$itemid'");
$items = array();
while($row = mysql_fetch_object($rs)){
    array_push($items, $row);
}
echo json_encode($items);

$itemid = $_REQUEST['itemid'];

include 'conn.php';

$rs = mysql_query("select * from lineitem where itemid='$itemid'");
$items = array();
while($row = mysql_fetch_object($rs)){
array_push($items, $row);
}
echo json_encode($items);
