alt="" />

一、定义easyui-combobox控件

    <table>
<tr>
<th class="style1">
调查地区:
</th>
<td>
<input id="cmbNetWork" class="easyui-combobox" name="dept" data-options="editable:false" />
</td>
<th class="style1">
频道:
</th>
<td>
<input id="cmbFmName" class="easyui-combobox" name="cmbFmName" data-options="editable:false" />
</td>
</tr>
</table>

二、javascript操作easyui-combobox的语法,绑定地区数据源,当选择地区以后触发loadCmbFM()方法,绑定频道数据源。

        $(document).ready(function () {
//加载地区信息
var cbotemplte = $("#cmbNetWork");
cbotemplte.combobox({
url: "AjaxHandler/RadioCommon.ashx?action=bindNetwork",//对应提供数据源的ashx页面
valueField: 'CNETWORKID',//绑定字段ID
textField: 'CNETWORKNAME',//绑定字段Name
onSelect: function (row) {
loadCmbFM(row.CNETWORKID);//执行选择操作后执行,row.CNETWORKID是当前选中行的地区ID
}
});
function loadCmbFM(networkID) {//根据地区ID绑定频道信息
$("#cmbFmName").combobox({
url: "AjaxHandler/RadioCommon.ashx?action=fmByNetworkID&networkID=" + networkID,
valueField: 'CFM_ID',
textField: 'CFM_CNAME'
});
}
})
</script>
