为什么已在IE中不显示上载的图像？
[英]Why Uploaded Image not being displayed in IE?
问题描述
I am using simple HTML page for upload and post image to servlet then I convert image in byte[] and save in session using doPost() method: 
我使用简单的HTML页面上传和发布图像到servlet，然后将图像转换为byte []并使用doPost()方法保存在会话中：
response.setContentType("text/html");
items = upload.parseRequest(request);
byte[] byteArray = item.get();
request.getSession().setAttribute("image1", byteArray);
out.println("<html>");
out.println("<body onload='javascript:callParent()'>File uploaded successfully.");
out.println("<img src='/ImageUpload' alt='' id='img2' name='img2' />");
out.println("</body>");
out.println("</html>");
in img tag's src i am calling same servlet and in doGet() get byte[] stored in session and send them back as following: 在img标签的src中，我正在调用相同的servlet，在doGet（）中，获取存储在会话中的byte []并将它们发送回，如下所示：
response.setContentType("image/jpeg");
byte[] byteArray =(byte[])request.getSession().getAttribute("image1");
OutputStream output = response.getOutputStream();
output.write(byteArray);
output.close();
This code working fine in Mozilla but not working in IE only red X is being displayed but img tag is getting wide according to image size but not displayed any thing. 此代码在Mozilla中工作正常，但在IE中不工作，仅显示红色X，但img标签根据图像大小变宽，但未显示任何内容。 also when I click submit button twice then form get submitted in IE in other it is being submit in one click. 另外，当我单击提交按钮两次，然后在IE中以其他方式提交表单时，只需单击一下即可提交。
I am using IE-8 and image is of type .JPEG. 我正在使用IE-8，图像的类型为.JPEG。 is there is any setting issue I tried to search on web but no any result. 我尝试在网络上搜索是否有任何设置问题，但没有任何结果。

您的问题是您关闭了输出流，因此它无法继续加载。

Actually i was using onload() event of body tag to open browse button automatically. 实际上，我是使用body标签的onload（）事件自动打开浏览按钮的。
<body onload='frm1.imgUpload.click()'>
<form action="ImgUpload" method="POST" enctype="multipart/form-data" name="frm1" id="frm1">
<input type='file' id = 'imgUpload' name = 'imgUpload' onchange='frm1.submit()' />
</form>
</body>
but when i remove code for opening browse through java script it started working fine with IE i don't know what is the problem with IE and java script now i am clicking browse button manually and everything is working. 但是，当我删除用于打开通过Java脚本浏览的代码时，它开始在IE中正常运行，我现在不知道IE和Java脚本有什么问题，我现在手动单击“浏览”按钮，一切正常。
