求助:根据菜单值调用图片?

我写了一个页面,在页面上空出了六个已命名的图像占位。
用select菜单实现不同图片的直接调用
不知道问题出在哪里

var str6 = new string ();

lan = $('.form1 select[@name="language"]').val();
//填充不同图片
if (lan="1"){str1="images/index-cn.gif";
str2="images/index-cn_r3_c1.gif";
str3="images/index-cn_r3_c2.gif";
str4="images/index-cn_r3_c3.gif";
