dojo中取查询出来的地市维表数据的id

1、页面中引入隐藏域

<input type="hidden" id="area_desc"/>

2、通过在属性中设置

onchange:function(val){
    document.getElementById('area_desc').value = val;
}

3、在<span></span>写事件

<script type="dojo/on" data-dojo-event="change">
    document.getElementById('area_desc').value = this.item.id;
</script>
