面对这里的奇怪情况。以下代码甚至在IE中工作正常，但在某些IE中它产生以下错误，只是不知道它为什么会来，以及如何解决这个问题。请帮帮我。
// controller side code
@RequestMapping(value = "upload", method=RequestMethod.POST)
public @ResponseBody String upload(HttpServletRequest request, HttpServletResponse response,
@RequestPart("dataFile") MultipartFile file
){ if(file!=null){
//code to upload file and will return 1
return "1";
}
return "0";//otherwise it will return 0
}
// javascript中的代码，它将iframe（提交表单）提交给控制器
<html>
<script language="Javascript">
function fileUpload(form, action_url, div_id) {
// Create the iframe...
var iframe = document.createElement("iframe");
iframe.setAttribute("id", "upload_iframe");
iframe.setAttribute("name", "upload_iframe");
iframe.setAttribute("width", "0");
iframe.setAttribute("height", "0");
iframe.setAttribute("border", "0");
iframe.setAttribute("style", "width: 0; height: 0; border: none;");
// Add to document...
form.parentNode.appendChild(iframe);
window.frames['upload_iframe'].name = "upload_iframe";
iframeId = document.getElementById("upload_iframe");
// Add event...
var eventHandler = function () {
if (iframeId.detachEvent) iframeId.detachEvent("onload", eventHandler);
else iframeId.removeEventListener("load", eventHandler, false);
// Message from server...
if (iframeId.contentDocument) {
content = iframeId.contentDocument.body.innerHTML;
} else if (iframeId.contentWindow) {
content = iframeId.contentWindow.document.body.innerHTML;
} else if (iframeId.document) {
content = iframeId.document.body.innerHTML;
}
document.getElementById(div_id).innerHTML = content;
// Del the iframe...
setTimeout('iframeId.parentNode.removeChild(iframeId)', 250);
}
if (iframeId.addEventListener) iframeId.addEventListener("load", eventHandler, true);
if (iframeId.attachEvent) iframeId.attachEvent("onload", eventHandler);
// Set properties of form...
form.setAttribute("target", "upload_iframe");
form.setAttribute("action", action_url);
form.setAttribute("method", "post");
form.setAttribute("enctype", "multipart/form-data");
form.setAttribute("encoding", "multipart/form-data");
// Submit the form...
form.submit();
document.getElementById(div_id).innerHTML = "Uploading...";
}
</script>
//html code
<!-- index.php could be any script server-side for receive uploads. -->
<form>
<input type="file" name="dataFile" id="dataFile" /></br>
<input type="button" value="upload"
onClick="fileUpload(this.form,'upload','uploadShow'); return false;" >
<div id="uploadShow"></div>
</form>
</html>
