function delete_new()

for(i=0; i {
el = document.all("news_select").item(i);
if(el.checked)
{
val = el.value;
delete_str += val + ",";
}
}

if(i == 0)
{
el = document.all("news_select");
if(el.checked)
{
val = el.value;
delete_str += val + ",";
}
}

if(delete_str == "")
{
alert("要删除新闻，请至少选中其中一条。");
return true;
}

msg = "确认要删除该新闻么？";
if(window.confirm(msg))
{
url = "do.php?id_str="+ delete_str +"&operate=delete";
window.location = url;
}
}



[/PHP]
以上代码应该没问题，window.location = url;
为什么这句就没执行
注：delete_str的值是36,
既do.php?id_str=36,&operate=delete
不知道值加逗号有没有问题，注明
