城市類太大了，發(fā)不了。

怎么用php讀取數(shù)據(jù)庫(kù)方式動(dòng)態(tài)生成省市縣三級(jí)聯(lián)動(dòng)選擇框
需要使用到ajax。到網(wǎng)上查下，一堆。代碼是固定的。
數(shù)據(jù)庫(kù)設(shè)置
id,area,areaname
1 210000 遼寧省
2 210100 沈陽(yáng)市
3 210104 大東區(qū)
select name='area1' id='area1' onchange="get_area2(this.value);"
這里讀取省的數(shù)據(jù)
$sql="select area,areaname from area where right(area,4)='0000'";
/select
select name='area2' id='area2 'onchange="get_area(this.value);"
這里根據(jù)ajax讀取數(shù)據(jù)，開始的時(shí)候是空的
/select
select name='area' id='area'
這里根據(jù)ajax讀取數(shù)據(jù)，開始的時(shí)候是空的
/select
方法：
1，首先寫get_area2 的js 代碼，這里就用到ajax讀取，這里獲取的數(shù)據(jù)是區(qū)域代碼的前兩位代碼（比如：21）
這個(gè)在根據(jù)這個(gè)21的參數(shù)，讀取表中相關(guān)的市，
$sql="select area,areaname from area where left(area,2)='21' and right(area,2)='00'";
這個(gè)語(yǔ)句讀取出來(lái)21的市代碼
2，同一讀取出來(lái)區(qū)的代碼
