js實(shí)現(xiàn)全國(guó)省份城市級(jí)聯(lián)下拉菜單效果代碼

 更新時(shí)間：2015年09月07日 09:37:17   作者：企鵝  
這篇文章主要介紹了js實(shí)現(xiàn)全國(guó)省份城市級(jí)聯(lián)下拉菜單效果代碼,通過JavaScript針對(duì)數(shù)組的定義與元素的遍歷實(shí)現(xiàn)省市級(jí)聯(lián)菜單功能,非常具有實(shí)用價(jià)值,需要的朋友可以參考下

本文實(shí)例講述了js實(shí)現(xiàn)全國(guó)省份城市級(jí)聯(lián)下拉菜單效果代碼。分享給大家供大家參考。具體如下：

這是一個(gè)大家都知道的網(wǎng)頁小功能，很常見，全國(guó)省份與城市級(jí)聯(lián)菜單，采用Select下拉的方式選擇數(shù)據(jù)，不過現(xiàn)在很多都Ajax了，貌似這種老形式已經(jīng)過時(shí)了，不過在兼容性方面，仍然是不落后的。

運(yùn)行效果截圖如下：

在線演示地址如下：
