Unfortunately, IE9 does not support FormData, making file uploads via XMLHttpRequest a more challenging task.
Is there a workaround for this issue? I've come across mentions of using iFrames, but the process seems complex and unclear on how to transfer files from the iFrame to the server.
Without relying on third-party libraries, is there a way to asynchronously upload files using plain JavaScript and without utilizing FormData?
If you're looking to handle file uploads in IE9 using XHR, this code snippet might be helpful. It involves creating a file input element within a form, adding credentials, submitting the form to an iframe, and retrieving the response.
Here's a breakdown of what the code does:
// JavaScript code for file upload
fileSelection = document.createElement("div");
// More code follows...
In the provided JavaScript code snippet, a file input element is created along with additional form elements to handle the file upload process. The function doUploadObjectUpload() handles the submission to an iframe while followUpOnHTML4Upload(frameId) can be used to process the server response.
After uploading, PHP, for example, can access uploaded files via the $_FILES global variable.
