只需要改动这个函数就行了
function change(){ if(!document.all) return if (event.srcElement.id=="foldheader") { var srcIndex = event.srcElement.sourceIndex var checkedFlag = document.all[srcIndex+1].checked var nested = document.all[srcIndex+2] if (nested.style.display=="none") { if(checkedFlag==false) { nested.style.display='' event.srcElement.style.listStyleImage="url(open.gif)" } } else { nested.style.display="none" event.srcElement.style.listStyleImage="url(fold.gif)" } } } |

老兄：加了这段都不能点开了。

才20分啊。太少了

你选中了那个checkbox就不能点开，没选中还是可以点开的，这不是你自己的要求吗？
