Easyui form combobox省市区三级联动可以帮助用户快速选择省市区的信息,提供了良好的用户体验。下面我们来详细讲解该功能的完整攻略。

实现步骤

第一步:引入EasyUI资源文件和jQuery库文件

<link rel="stylesheet" type="text/css" href="https://cdn.bootcdn.net/ajax/libs/jquery-easyui/1.9.9/themes/default/easyui.css"/>
<link rel="stylesheet" type="text/css" href="https://cdn.bootcdn.net/ajax/libs/jquery-easyui/1.9.9/themes/icon.css"/>  
<script type="text/javascript" src="https://cdn.bootcdn.net/ajax/libs/jquery/1.11.3/jquery.min.js"></script>  
<script type="text/javascript" src="https://cdn.bootcdn.net/ajax/libs/jquery-easyui/1.9.9/jquery.easyui.min.js"></script>

第二步:定义三个下拉框

<input id="province" class="easyui-combobox" data-options="url:'getProvince.php',valueField:'id',textField:'name',onSelect:function(rec){}">
<input id="city" class="easyui-combobox" data-options="url:'getCity.php',valueField:'id',textField:'name',onSelect:function(rec){}">
<input id="district" class="easyui-combobox" data-options="url:'getDistrict.php',valueField:'id',textField:'name'">

第三步:编写三个数据源

getProvince.php

<?php
$data = array(
            array('id'=>'1','name'=>'北京'),

        break;
    default:
        break;
}

echo json_encode($data);
?>

第四步:实现省市区三级联动

$(function(){
    $('#province').combobox({
        onSelect:function(rec){
            var url = 'getCity.php?id='+rec.id;
            $('#city').combobox('clear').combobox('reload', url);
            $('#district').combobox('clear');
        }
    });
    $('#city').combobox({
        onSelect:function(rec){
            var url = 'getDistrict.php?id='+rec.id;
            $('#district').combobox('clear').combobox('reload', url);
        }
    });
});

示例

示例一:全国省市区三级联动

以下是一个全国省市区三级联动示例,你可以查看和体验该功能。在省、市、区三级下拉框中选择对应选项,可以动态联动加载下级选项。
