${packageSearch.models['packageColumnHeader'].packageColumnHeaderList}
请问以上这个语句是什么意思呢？调用packageSearch里面的models方法？在页面里没
有看到定义
packageSearch，是说这是个javabean？刚刚上班学了两天jsp，实在是不明白，请大家
指点啊！啥
都不会，工作压力好大…… | h**********c

web framework mapping a page. models is a map containing the dynamic data,
packageColumnHeader is a key name in the map, packageColumnHeaderList is a
field in the instance for the value that mapped to packageColumnHeader key
class PackageSearch{
Map models;
}
class PackageColumnHeader {
PackageColumnHeaderList packageColumnHeaderList;
}
models.put("packageColumnHeader", new PackageColumnHeader());
class BlahServlet {
PackageSearch packageSearch = new PackageSearch();
