关于闭包的问题

Question

varblockLength=0;
$("#divadd"+blockLength).click(function(){
if(blockLength<5){
$(".muiltiRouteClass"+blockLength).attr("style","");
$("#divminus"+blockLength).show();
if(blockLength==5){$("#divadd"+blockLength).css("visibility","hidden");}
if(blockLength==2){$("#divminus"+blockLength).css("display","none");}
}
blockLength++;
});
如上面代码，最开始的按钮id是divadd2，点击之后，将隐藏的divadd3显示出来。这时候blockLength++按钮的id是divadd3，请问点击之后，怎么重新给点击的按钮赋新的id。在线等，谢谢
