我的目的是单击table1的某一行,使这一行变颜色,temp.cells[i].className= "clickchoose ";就实现了变颜色.然后按键盘上的向下箭头键,选中该行的下一行.
现在的问题是,单击选中了之后,再按向下箭头键的话,总是从第一条开始变颜色.
好象是这样操作单击之后没有给str赋值一样,但实际上是赋值了啊.为什么一按向下的箭头,str为什么会重新刷新为0呢?
我的这个页面在另一个页面的iframe里,是不是因为这个问题啊?
[解决办法]
是不是按向下的箭头之后，页面就被刷新了啊。
把var str=0;去掉看看。
另外在js脚本中加alert看看每一步str的变化。
