JS参数传值问题

[BKscofild]

<select id="kldm" name="kldm" onchange="test(this);">

function test(obj){
refreshKMZ(obj,'kmzdm');
setTimeout("refreshYX(obj,'yxdm1')",1000);
}

refreshYX()的参数obj得到的不是kldm的对象？
怎么才能得到？

[dh20156]

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

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？

<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
