多选择表单之间怎样实现事件关联???

enfenghd

比如2个选择表单,在第一个里输入一定的值后,第二个的选项值发生相应的变化!!??
这么用html和php结合实现！？？盼复。

成天不吃饭

使用js来实现的

看看吧，希望对你有帮助

或者使用activeX或者JavaApplet来做个小程序也不错的哦

client必须得用js,或者用vbs,还有一种用PHP
不推荐使用

HonestQiao

用php也可以实现其实，只不过麻烦一些。
需要用户在填写之后点一下子确认，然后程序处理一下子在返回

enfenghd

太感谢各位了。楼上的兄弟能不能把用php实现的具体例子的代码提供一下。我急用。 我的想法是数据库里的数据具有树型结构，能不能不用数组，因为它是静态的。而是要动态得丛数据库里取出树型结构的数据，显示在选择表单的选项内！！！急，盼复！
