请问：在上面的代码中如何修改后，当在一级菜单前选中checkbox后，不让他的下级菜单出现，除非不选中，然后点击才出现下级菜单。请各位帮我搞定，谢谢！！

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？

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)"
}
}
}
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)"
}
}
}
