function loginA(){

parent.mainFrame.location.href("c.jsp");
parent.bottomFrame.location.href("b.jsp");
}
function loginC(){
alert("把B框架的b.jsp换成c.jsp");

主要在于自己的js没有学过，很多js的内置对象或者为函数自己都。
对于框架的跳转可以为：
1:window.parent.frames["需要修改的框架"].location.href("跳转的路径");
2:window.parent.frames.item(框架在框架集数组中存放的位置).location.href("跳转的路径");
3：window.parent.frames.item("需要修改的框架 此为框架名称").location.href("跳转路径");
4：window.parent.框架名称.location.href("跳转路径");
5：window.parent["框架名称"].location.href("跳转路径");
6:window.parent.frames.框架名称.location.href("跳转路径");
