组合网格（combogrid）把可编辑的文本框和下拉数据网格面板结合起来，用户可以从下拉数据网格面板中快速查找和选择。组合网格（combogrid）提供了选择某个项目的键盘导航支持。
<select id="cc" class="easyui-combogrid" name="dept" style="width:250px;"
data-options="
panelWidth:450,
value:'006',
idField:'code',
textField:'name',
url:'datagrid_data.json',
columns:[[
{field:'code',title:'Code',width:60},
{field:'name',title:'Name',width:100},
{field:'addr',title:'Address',width:120},
{field:'col4',title:'Col41',width:100}
]]
"></select>
（2）、使用 javascript 从已有的 <select> 或 <input> 元素创建。
<input id="cc" name="dept" value="01">
$('#cc').combogrid({
panelWidth:450,
value:'006',
idField:'code',
textField:'name',
url:'datagrid_data.json',
columns:[[
{field:'code',title:'Code',width:60},
{field:'name',title:'Name',width:100},
{field:'addr',title:'Address',width:120},
{field:'col4',title:'Col41',width:100}
]]
});
（3）、自动完成功能
让我们为组合网格（combogrid）提那家自动完成功能。下拉数据网格将根据用户输入显示可能的结果。
$('#cc').combogrid({
delay: 500,
mode: 'remote',
url: 'get_data.php',
idField: 'id',
textField: 'name',
columns: [[
{field:'code',title:'Code',width:120,sortable:true},
{field:'name',title:'Name',width:400,sortable:true}
]]
});
（4）、在服务器端，'q' 参数必须首先被检索。用户可以查询数据库，然后返回一个 JSON 格式的 sql 结果到浏览器。
get_data.php:
$q = isset($_POST['q']) ? $_POST['q'] : ''; // the request parameter
// query database and return JSON result data
$rs = mysql_query("select * from item where name like '$q%'");
echo json_encode(...);

1、用法
（1）、从标记创建组合网格（combogrid）。<select id="cc" class="easyui-combogrid" name="dept" style="width:250px;"
data-options="
panelWidth:450,
value:'006',
idField:'code',
textField:'name',
url:'datagrid_data.json',
columns:[[
{field:'code',title:'Code',width:60},
{field:'name',title:'Name',width:100},
{field:'addr',title:'Address',width:120},
{field:'col4',title:'Col41',width:100}
]]
"></select>
（2）、使用 javascript 从已有的 <select> 或 <input> 元素创建。
<input id="cc" name="dept" value="01">
$('#cc').combogrid({
panelWidth:450,
value:'006',
idField:'code',
textField:'name',
url:'datagrid_data.json',
columns:[[
{field:'code',title:'Code',width:60},
{field:'name',title:'Name',width:100},
{field:'addr',title:'Address',width:120},
{field:'col4',title:'Col41',width:100}
]]
});
（3）、自动完成功能
让我们为组合网格（combogrid）提那家自动完成功能。下拉数据网格将根据用户输入显示可能的结果。
$('#cc').combogrid({
delay: 500,
mode: 'remote',
url: 'get_data.php',
idField: 'id',
textField: 'name',
columns: [[
{field:'code',title:'Code',width:120,sortable:true},
{field:'name',title:'Name',width:400,sortable:true}
]]
});
（4）、在服务器端，'q' 参数必须首先被检索。用户可以查询数据库，然后返回一个 JSON 格式的 sql 结果到浏览器。
get_data.php:
$q = isset($_POST['q']) ? $_POST['q'] : ''; // the request parameter
// query database and return JSON result data
$rs = mysql_query("select * from item where name like '$q%'");
echo json_encode(...);
2、属性
该属性扩展自组合（combo）和数据网格（datagrid），下面是为组合网格（combogrid）添加的属性。| 名称 | 类型 | 描述 | 默认值 |
| loadMsg | string | 当数据网格（datagrid）加载远程数据时显示的消息。 | null |
| idField | string | id 的字段名。 | null |
| textField | string | 显示在文本框中的 text 字段名。 | null |
| mode | string | 定义当文本改变时如何加载数据网格（datagrid）数据。如果组合网格 （combogrid）从服务器加载就设置为 'remote'。当设置为 'remote' 模式时，用户输入的值将会被作为名为'q' 的 http 请求参数发送到服 务器，以获取新的数据。 | local |
| filter | function(q, row) | 定义当 'mode' 设置为 'local' 时如何选择本地数据。返回 true 则选择该行。 | 100 |
3、方法
该方法扩展自组合（combo），下面是为组合网格（combogrid）添加或重写的方法。| 名称 | 参数 | 描述 |
| options | none | 返回选项（options）对象。 |
| grid | none | 返回数据网格（datagrid）对象。 |
| setValues | values | 设置组件值的数组。 |
| setValue | value | 设置组件的值。 |
| clear | none | 清除组件的值。 |
