焦点onchange,怎么判断已经执行内框架的文件?

[zyhowe]

function changeMerchantGroup(merch_group_id){
if(merch_group_id!="")
frameTemp.location.href = "../find/FindMerchantGroup.asp?merch_group_id=" +merch_group_id;
if(frameTemp.document.readyState=="complete")return;
}


<tr>
<td class="td_left">Merchant Group ID</td>
<td class="td_right" colspan="3">
<input type="text" name="merch_group_id" size="20" maxlength="6" onchange="changeMerchantGroup(document.all.merch_group_id.value)">
<iframe name="frameTemp" url="" width="0" height ="0"></iframe>
</td>
</tr>

var record=""
function changeMerchantGroup(merch_group_id){
if(merch_group_id!="" && merch_group_id!=record)
{
frameTemp.location = "../find/FindMerchantGroup.asp?merch_group_id=" +merch_group_id;
record=merch_group_id;
}
if(frameTemp.document.readyState=="complete")return;
}

<tr>
<td class="td_left">Merchant Group ID</td>
<td class="td_right" colspan="3">
<input type="text" name="merch_group_id" size="20" maxlength="6" onchange="changeMerchantGroup(this.value)">
<iframe name="frameTemp" url="" width="0" height ="0"></iframe>
</td>
</tr>

一个人啊。。。

function changeMerchantGroup(merch_group_id){
if(merch_group_id!="")
frameTemp.location.href = "../find/FindMerchantGroup.asp?merch_group_id=" +merch_group_id;
if(frameTemp.document.readyState=="complete")return;//个人认为在此处frameTemp.document.readyState永远是"loading",只有本函数返回，浏览器才会去做链接的，除非浏览器支持多线程
}

<iframe name="frameTemp" url="" width="0" height ="0"></iframe>
把这个改一下：
<iframe name="frameTemp" url="" width="300" height ="100"></iframe>

解决:
function changeMerchantGroup(merch_group_id){
if(merch_group_id!=""){
frameTemp.parent.document.body.setCapture();
frameTemp.location.href = "../find/FindMerchantGroup.asp?merch_group_id=" +merch_group_id;
}
}

焦点事件对应的文件FindMerchantGroup.asp加
<script language="javascript">
parent.document.body.releaseCapture();
</script>
