使用combobox自定义的级联下拉列表框:源码如下:
<head> <link rel="stylesheet" type="text/css" href="../themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="../themes/icon.css"> <link rel="stylesheet" type="text/css" href="../themes/demo.css"> <script type="text/javascript" src="../js/jquery.js"></script> <script type="text/javascript" src="../js/jquery.easyui.min.js"></script> <meta charset="UTF-8"> <title>coboboxTest</title> <script type="text/javascript"> $(function(){ $('#cityId').combobox({ valueField:'orgNo', textField:'orgName', onSelect:function (record) { // alert("orgNo:"+record.orgNo +", orgName:"+record.orgName); var county = record.county; $('#countyId').combobox('clear'); $('#countyId').combobox('loadData',county); } }); $.getJSON('cityJson.json',function(data){ $('#cityId').combobox('loadData',data); // $('#cityId').combobox('select','41401'); $('#cityId').combobox('select','郑州'); }); }); </script> </head> <body> 市: <input type="text" id="cityId" name="cityId"/><br/> 县: <input type="text" id="countyId" name="countyId" class="easyui-combobox" data-options="valueField:'orgNo',textField:'orgName'"/> </body> </html>
效果图:
首先:需要引入所需的文件
<link rel="stylesheet" type="text/css" href="../themes/default/easyui.css"> <link rel="stylesheet" type="text/css" href="../themes/icon.css"> <link rel="stylesheet" type="text/css" href="../themes/demo.css"> <script type="text/javascript" src="../js/jquery.js"></script> <script type="text/javascript" src="../js/jquery.easyui.min.js"></script>
<input type="text" id="countyId" name="countyId" class="easyui-combobox" data-options="valueField:'orgNo',textField:'orgName'"/>或者使用JS:
$('#cityId').combobox({ valueField:'orgNo',//绑定的数据value textField:'orgName',//绑定的数据text onSelect:function (record) {//选中后触发的事件 // alert("orgNo:"+record.orgNo +", orgName:"+record.orgName); var county = record.county; $('#countyId').combobox('clear'); $('#countyId').combobox('loadData',county);//加载县区 } });
[ { "orgNo":"41401","orgName":"郑州", "county":[ {"orgNo":"4140101","orgName":"新郑"}, {"orgNo":"4140102","orgName":"中牟"} ] }, { "orgNo":"41402", "orgName":"南阳", "county":[ {"orgNo":"4140201","orgName":"唐河"}, {"orgNo":"4140202","orgName":"卧龙"} ] }, { "orgNo":"41403","orgName":"信阳", "county":[ {"orgNo":"4140301","orgName":"罗山县"}, {"orgNo":"4140302","orgName":"光山县"} ] }, { "orgNo":"41404","orgName":"洛阳", "county":[ {"orgNo":"4140401","orgName":"新安县"}, {"orgNo":"4140402","orgName":"伊川县"} ] } ]
至此,功能完成。
此时,可以根据具体的功能需求,自己创建三级乃至更多级别的级联。
