I am trying to upload a file to server using JavaScript as dynamically generating a form along with input file while clicking a button.
But here, uploading File is not appending to form tag inside the script, so that upload function not works.
My code in html file as follows,
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>File Upload</title>
</head>
<body>
<div id="formActive">
<button onclick="imageContent();">click</button>
</div>
<script>
function imageContent(){
var imgContent = "file";
var fileContent = document.createElement('input');
fileContent.name = 'file';
fileContent.type = 'hidden';
var lastImageFile = "imageName";
var boundary=Math.random().toString().substr(2);
multipart = "--" + boundary
+ "\r\nContent-Disposition: form-data; name=" + lastImageFile
+ "\r\nContent-type: application/octet-stream"
+ "\r\n\r\n" + imgContent + "\r\n";
multipart += "--"+boundary+"--\r\n";
fileContent.value = imgContent;
var form = document.createElement('form');
form.method = "POST";
form.action = "mydomain.com/upload";
form.enctype = "multipart/form-data";
form.appendChild(fileContent);
document.getElementById("formActive").appendChild(form);
form.submit();
}
</script>
</body>
</html>
While looking into the upload servlet, I didn't get any file name in request.
Can anyone assist that where I did mistake?
