JS参数传值问题

Question

setTimeout("refreshYX(obj,'yxdm1')",1000);
-->
setTimeout(function(){refreshYX(obj,'yxdm1')},1000);

Answer 1

这个行
但3个就不行了refreshYX(ll,'yxdm2');
setTimeout(function(){refreshKMZ(ll,'kmzdm')},500);
setTimeout(function(){refreshZY(ll,'yxdm1')},500);象这样就只有两个行？

Answer 2

<select id="kldm" name="kldm" onchange="test(this);">function test(obj){
refreshKMZ(obj,'kmzdm');
setTimeout(function () {
     refreshYX(obj,'yxdm1');
     },1000);
}setTimeOut不能使用参数，必须使用委托
