JavaScript实现省市区三级联动
本文实例为大家分享了JavaScript实现省市区三级联动的具体代码，供大家参考，具体内容如下
首先是js
$(document).ready(function(){
getErpMarketByParentCode(0,'province',province);
getErpMarketByParentCode(province,'city',city);
getErpMarketByParentCode(city,'area',area);
getErpMarketByParentCode(area,'market',market);
$('#city').append($('
然后是后台方法
@RequestMapping(value="/getErpMarketByParentCode")
publicModelAndViewgetErpMarketByParentCode(HttpServletRequestrequest,HttpServletResponseresponse)throwsException{
Stringcode=request.getParameter("code");
ListerpMarketList=erpMarketService.getErpMarketListByParentCode(code);
JSONObjectjsonObject=newJSONObject();
jsonObject.put("erpMarketList",erpMarketList);
response.getWriter().write(jsonObject.toString());
returnnull;
}
service方法，是从内从中获取省市区这张表
publicListgetErpMarketListByParentCode(StringparentCode){ HashtableerpMarketTable=LoadOnStartService.erpMarketTable;//从内存中获取这张表 List erpMarketList=newArrayList (); Iteratorits=erpMarketTable.keySet().iterator(); while(its.hasNext()){ Stringkey=Util.getString(its.next()); ErpMarketerpMarket=(ErpMarket)erpMarketTable.get(key); if(parentCode.equals(erpMarket.getParentCode())){ erpMarketList.add(erpMarket); } } returnerpMarketList; }
省市区的实体类
packagecom.erp.entity;
/**
*ErpMarketentity.
*
*@authorMyEclipsePersistenceTools
*/
publicclassErpMarketimplementsjava.io.Serializable{
//Fields
privateStringcode;
privateStringshortCode;
privateStringname;
privateStringlevel;
privateStringparentCode;
//Constructors
/**defaultconstructor*/
publicErpMarket(){
}
/**fullconstructor*/
publicErpMarket(StringshortCode,Stringname,Stringlevel,StringparentCode){
this.shortCode=shortCode;
this.name=name;
this.level=level;
this.parentCode=parentCode;
}
//Propertyaccessors
publicStringgetCode(){
returnthis.code;
}
publicvoidsetCode(Stringcode){
this.code=code;
}
publicStringgetShortCode(){
returnthis.shortCode;
}
publicvoidsetShortCode(StringshortCode){
this.shortCode=shortCode;
}
publicStringgetName(){
returnthis.name;
}
publicvoidsetName(Stringname){
this.name=name;
}
publicStringgetLevel(){
returnthis.level;
}
publicvoidsetLevel(Stringlevel){
this.level=level;
}
publicStringgetParentCode(){
returnthis.parentCode;
}
publicvoidsetParentCode(StringparentCode){
this.parentCode=parentCode;
}
}
