关于option城市选择源码的信息
本文目录一览：
- 1、代码中选省，当是没有显示城市选择，是否代码有问题，有请说明
- 2、请问如何实现：在网页中选择了国家，下面自动出现该国家的省名供选择
- 3、从网上下载了个级联菜单选择城市的JS 发现获取到的是城市代码 怎么获取城市名？
- 4、jquery 下来框选中省份；弹出该省份的城市复选框 求全代码。jquery不是很懂
代码中选省，当是没有显示城市选择，是否代码有问题，有请说明
当然有!
阿城区距哈尔滨市中心区 23 公里 ，基本地貌为“六山一水三分田”，西部平原坦荡如砥，东部山区峰峦叠翠。幅员面积 2500 平方公里，辖 5 乡 9 镇、 5 个街道办事处、 108 个行政村，总人口 58 万，其中市区人口 22.7 万。阿城区是省内哈大齐工业走廊的哈尔滨内环区，是哈尔滨对俄贸易的重要交通枢纽和窗口，已逐步成为黑龙江省面向全国开放的一个重要窗口。
公元 1115 年，女真族首领完颜阿骨打建立大金帝国，定都今阿什河畔白城村，史称“金上京会宁府”，历经 4 帝 38 年。清宣统元年（ 1909 年）设县，称阿勒楚喀城，简称阿城。 1987 年 2 月，经国务院批准撤县建市， 1996 年被评为黑龙江省历史文化名城。 2000 年、 2002 年和 2004 年，阿城市成功举办了三届中国·阿城金源文化节，扩大了阿城的影响，提高了阿城的知名度。 2006 年经国务院批准撤市建区，成为哈尔滨市的一个新区。
请问如何实现：在网页中选择了国家，下面自动出现该国家的省名供选择

从网上下载了个级联菜单选择城市的JS 发现获取到的是城市代码 怎么获取城市名？
a","b","c","d"];
arr[1]=["c++","oracle","sql","js"];数组下标为0option城市选择源码的有"a","b","c","d";
数组下标为1的有"c++","oracle","sql","js"option城市选择源码，
var i=document.form1.selterm.selectedIndex-1;这句话其实跟op=new Option(arr[i][j],arr[i][j]);有关，举个例子，选择1学期的时候，document.form1.selterm.selectedIndex为1，-1之后为0，然后找到arr[0]，也就是["a","b","c","d"]），然后new出一个Option(arr[0][j],arr[0][j]);（一个option包含显示的内容和value值。)在清空之后，select下面是空的，必须加一个请选择的option填充，其实把下标修改一下，arr[1]=["a","b","c","d"];
arr[2]=["c++","oracle","sql","js"];这时候var i=document.form1.selterm.selectedIndex就可以option城市选择源码了，不需要减1option城市选择源码了，不知道option城市选择源码你是否明白意思了
另外,虚机团上产品团购,超级便宜
jquery 下来框选中省份；弹出该省份的城市复选框 求全代码。jquery不是很懂
百度 jquery 省市联动
一般都是带后台语言和数据库option城市选择源码的
单纯jquery写option城市选择源码的太长也不咋实用
