通过xpath定位元素：

var u = "xiaohuangya";
var p = "password123";

var user_name = document.evaluate("//div/label/input",document).iterateNext();
if(null!= user_name){user_name.value = u;}

var user_pwd = document.evaluate("//div/label/input",document).iterateNext();
if(null!= user_pwd){user_pwd.value = u;}

通过ID定位元素：

var u = "xiaohuangya";
var p = "password123";

var user_name = document.getElementById("userNameId");
if(null!= user_name){user_name.value = u;}
var pwd = document.getElementById("pwdId");
if(null!= pwd){pwd.value = p;}
else
{
	 var frame_list = document.getElementByTagName('content');
	 if(0 == frame_list.length)
	 {
	 	//now is in relogin.jsp
	 	document.getElementById('username').value = u;
	 	document.getElementById('password').value = p;
	 	document.getElementById('btn_submit').value.click();}
	 else{
	 for(var i = 0;i<frame_list.length;i++)
	 {
	 	var node = frame_list[i];
	 	var src = node.getAttribute('src');
	 	//if(null != src && src.endsWith("relogin.jsp"))
	 	//{
	 		try{
	 			node.contentDocument.getElementById('username').value=n;
	 			node.contentDocument.getElementById('password').value=p;
	 			node.contentDocument.getElementById('btn_submit').click();
	 			}catch{}
	 			//}
	 			}
	 	}
}
document.getElementById('btn_submit').value.click();}
