怎么用js获取当前页的主域名后改变iframe的src地址
当网页地址栏主域名不为C时，iframe的src地址默认为B，当网页地址栏主域名为C时，iframe的src地址就换成了D，请问这个用js如何实现？
我想的是这样的：
<script type="text/javascript">
function ()
{
var locurl = window.location.host; //获取当前页主域名
if(var locurl = 'C')
{
document.getElementById("tiaozhuan").src='D'
}
}
</script>
<iframe id="tiaozhuan" src="B" scrolling="no" frameborder="0" marginwidth="0px" marginheight="0px"></iframe>
但是不对，请问正确的js应该怎样写？
