帮助改一下变量传递

给个类似的做参考<head><style type="text/css">
<!--
.opacity {
FILTER: alpha(opacity=100)
}
-->
</style><SCRIPT>
function movstar(obj,a,time){
movx=setInterval("mov("+obj+","+a+")",10)
}
function movover(){
clearInterval(movx)
}
function mov(objiframe,a){
if (objiframe==1){
scrollx=new_date0.document.body.scrollLeft
scrolly=new_date0.document.body.scrollTop
scrolly=scrolly+a
new_date0.window.scroll(scrollx,scrolly)
  }
else {
scrollx=new_date.document.body.scrollLeft
scrolly=new_date.document.body.scrollTop
scrolly=scrolly+a
new_date.window.scroll(scrollx,scrolly)
   }
}
function o_down(theobject){
object=theobject
while(object.filters.alpha.opacity>60){
object.filters.alpha.opacity+=-10}
}
function o_up(theobject){
object=theobject
while(object.filters.alpha.opacity<100){

}
function wback(){
if(new_date.history.length==0){window.history.back()}
else{new_date.history.back()}
}

  1.   

    你的movstar函数加多了一个参数之后有的地方还是按老的格式调用，会造成传递空指针。自然是不行。按新格式调用的直接把iframe1对象当参数传递给movstar，在movstar里面又把它放进setTimeout里面，并做了字符串加法。字符串加法接收到对象的时候会试图进行toString操作，于是你其实得到的是mov(1,[object])。不信你在movstar里面改一下：function movstar(a,time,framename)
    {
    alert("mov("+a+","+framename+")")
    move=setInterval("mov("+a+","+framename+")",time)
    }问题出来了，怎么解决我就不罗嗦了。
