js在IE下报 object error

使用ajaxfileupload实现上传图片的功能，firefox下功能正常。在ie下报object error
出错的代码如下:

	function ajaxFileUpload()

	{

		$("#loading")

		.ajaxStart(function(){

			$(this).show();

		})

		.ajaxComplete(function(){

			$(this).hide();

		});

		$.ajaxFileUpload

		(

			{

				url:'upload.php?do=upload',

				secureuri:false,

				fileElementId:'fileToUpload',

				dataType: 'json',

				data:{name:'logan', id:'id'},

				success: function (data, status)

				{

					if(typeof(data.error) != 'undefined')

					{

						if(data.error != '')

						{

							alert(data.error+'abc');

						}else

						{

							document.getElementById('photo').value=data.msg;

							var node1 = document.getElementById('imgnode1');

							var text = 

							"<br><img src='"+data.msg

							+"' width='130' height='160' >"

							+"<form name='imgdel' id='imgdel' action='upload.php?do=delete' method='post'>"

							+"<input type='hidden' name='file' value='"+data.msg

							+"'><input type='button' onclick='return ajaxFileDelete();' value='删除'></form>";

							var node2 = document.getElementById('imgnode2');

							node2.innerHTML = text;

						}

					}

				},

				error: function (data, status, e)

				{

					alert(e);

				}

			}

		)



		return false;

	}

通过加alert，已经定位到是node2.innerHTML = text;出错。请大家帮忙看下是什么问题。

网页中相关的代码如下：

			<tr><th align="right">照片</th><td></td>

			<td><input name="photo" id="photo" value="" type="hidden" />

			<div id="imgnode1">

			<input type="file" size=28 name="file" id="fileToUpload" class="input" /> 

			<br />

			<input type="button" id="buttonUpload" onclick="return ajaxFileUpload();" value="上传" />

			</div>

			<div id="imgnode2"> </div>

			</td></tr>
