• 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)
