schoolfilter.oFilter   =   oFilter;
schoolfilter.oSchool   =   oSchool;
schoolfilter.oGrade     =   oGrade;
schoolfilter.oClass     =   oClass;

if((oFilter!=null)   &&   (oSchool!=null)){
schoolfilter.vFilter   =   oFilter.value;
oFilter.style.imeMode   =   'active ';
//oFilter.onPropertyChange   =   schoolfilter.onfilterchange;

oFilter.onchange   =   schoolfilter.onfilterchange;
}
}

数组而已。

var arr = {};

用该方法实现OOP。。。

这样,楼主估计好理解一些。

function Fname()
{
this.fID = 10;
this.fValue = " ";
this.toDo = function()
{
alert( "Method. ");
}
}
