第二步：js spa
function changeArea (areaId) {ip
changeAreaClassName(areaId);ci
｝get
function changeAreaClassName(id){it
document.getElementById("area"+id).className=" current ";io
for(var i=0;i<100;i++){
if(i != id && document.getElementById("area"+i)!=null){
document.getElementById("area"+i).className=" otherCur ";
}
}
}
第三步 ： css
