I need to implement a feature where, upon selecting a file using a FileUpload control, the file (image or other) is immediately sent to a designated server directory—no extra button should trigger the upload. This functionality should mimic Gmail’s file attachment process by automatically uploading the file right after selection. Can anyone provide guidance or an example of how to achieve this behavior?
I have worked on a similar feature before and managed to integrate it effectively. What I did was attach an event listener to the file input that activated immediately after file selection. This event handler used the Fetch API to push the file data to the server without waiting on any additional action. Though handling errors and ensuring graceful degradation required a bit of extra coding, the overall implementation significantly improved the user flow. I recommend checking out examples on combining Fetch with FormData to see practical applications of this approach.
hey, u could use the onchange event to auto fire a fetch call with formdata right after file selection. i did this in a project and it worked pretty wel, though you might have to tweak error-handlng a bit. hope this helps!
In a project I worked on recently, I implemented a similar auto-upload functionality using the file input’s change event. I chose to work with jQuery’s ajax method since it provided a straightforward way to send FormData immediately after a file was selected. The key was constructing the FormData object correctly and ensuring that the server was prepared to handle asynchronous uploads without user intervention. While testing, I encountered browser compatibility issues that required additional error handling, but overall, this approach greatly improved the user experience.
