JS 实现省市联动
使用 JavaScript 实现选择省份,后面联动改变成相应省份下的市
原理很简单:
首先创建两个select下拉框(省、市)
初始化的时候让省都显示出来,市为空 ....................init()函数
选择省后,市下拉框里面显示出相应的城市,并定位一个城市到选择框....................provincechange()函数
代码如下:
<div class="form_con form_horizontal" id="form_con">
<div class="form_group">
<div class="form_item">
<label>所在地区:</label><select class="province" name="province" id="param_province" onchange="provincechange()"><option>请选择省份</option></select>
</div>
<div class="form_item">
<label>城市:</label><select class="city" name="city" id="param_city"><option>请选择城市</option></select>
</div>
</div>
</div>
var provinces = ['请选择省份','北京市','上海市','天津市','重庆市','河北省','山西省','内蒙古省','辽宁省','吉林省','黑龙江省','江苏省','浙江省','安徽省','福建省','江西省','山东省','河南省','湖北省','湖南省','广东省','广西省','海南省','四川省','贵州省','云南省','西藏省','陕西省','甘肃省','宁夏省','青海省','新疆省','香港','澳门','台湾'];
var citys = [['请选择城市'],
