distpicker三级联动，动态改变省市信息

一、引入3个js文件

　　<script type="text/javascript" src="js/distpicker.data.js"></script>

　　<script type="text/javascript" src="js/distpicker.js"></script>

　　<script type="text/javascript" src="js/main.js"></script>

二、页面展示

代码：

<div class="form-group">
                            <label class="col-lg-1 col-sm-1 control-label">通讯地址<font color="red">*</font></label>
                            <div class="col-lg-4 distpicker" data-toggle="distpicker">
                                <select id="province" name="province" data-province="---- 选择省 ----"></select>
                                <select id="city" name="city" data-city="---- 选择市 ----"></select>
                                <select id="district" name="district" data-district="---- 选择区 ----"></select>
                            </div>
                            <label class="col-lg-1 col-sm-1 control-label">通讯地址补充信息<font color="red">*</font></label>
                            <div class="col-lg-4">
                                <input type="text" class="form-control" id="addressExtra" placeholder="住址" value="${(empList.address_extra)!''}" name="addressExtra" >
                            </div>
                        </div>

初始化选项框的数据为选择省市区

$('.distpicker').distpicker('reset', true);
$('.distpicker1').distpicker('reset', true);

三、动态获取数据的三级联动

代码：

        var province = "${(empList.province)!''}";
        var city = "${(empList.city)!''}";
        var district = "${(empList.district)!''}";
   
        if(province!=null){
            var numbers = $("#province").find("option"); //获取select下拉框的所有值
            for (var j = 1; j < numbers.length; j++) {
                if ($(numbers[j]).val() == province) {
                    $(numbers[j]).attr("selected", "selected");
                    $('.distpicker').distpicker('output','city');//收到省的数据，市里面获取到这个省的所有市的名称
                }
            }
        }
        if(city!=null){
            var numbers = $("#city").find("option"); //获取select下拉框的所有值
            for (var j = 1; j < numbers.length; j++) {
                if ($(numbers[j]).val() == city) {
                    $(numbers[j]).attr("selected", "selected");
                    $('.distpicker').distpicker('output','district');
                }
            }
        }
        if(district!=null){
            var numbers = $("#district").find("option"); //获取select下拉框的所有值
            for (var j = 1; j < numbers.length; j++) {
                if ($(numbers[j]).val() == district) {
                    $(numbers[j]).attr("selected", "selected");
                }
            }
        }
