类似问卷调查的多个jsp提交时候出现问题

hubinjisu 2008-12-12 01:16:55

想做个类似问卷调查的项目，现在试着做鞋最简单的测试。我先写了两个jsp，在这两个jsp中每个都有一个文本显示的问题，只需回答yes或者no，yes和no是用下拉框显示的，默认是no。在用户回答完两个jsp的问题后将所有结果提交到第三个jsp中，在第三个jsp中做一个简单的分析，我现在只是测试，所以只要能输出几个yes，几个no就行了。我试着写了，可是问题很多。目前的问题是jsp中调用函数返回不了actionType值，总是null，不知道怎么回事。贴出来让大家看看，不知道我的想法能不能最后跑通
