a页面通过url传值，b页面如何接收（jquery.params.js实现）

用于两个html页面之间的传值

我的应用场景是：用echarts在a页面做完中国地图后，点击某个省份在b页面显示某个省份的地图。（在b页面显示点击了的那个省份的地图，等于说b页面是个“容器”页）

假设a页面js代码如下所示：

url='../html/province.html?ProvinceId='+cityMap[params.name]+'';//我这里的cityMap[params.name]是个变量，是在做echarts省市下砖时用到的这个传递参数、接收参数。

那么b页面就应该这样接收到ProvinceId的值，具体做法如下所示：

//得到a页面传来的省份id

var ProvinceId=$.query.get("ProvinceId");

console.log(ProvinceId);//打印a页面点击的省份id，显示该省地图

 

jquery.params.js（引入此js，否则无效果）
