javascript - How to set the default image path for input[file] and prevent it from popping up a dialog box to select a file.

Question

Now there is only one button to click submit to execute ajax, and then transfer the corresponding value to the server. Now there are problems with the image upload part:
1, if the default image path is not set through input[file], and Is there any way to directly submit the local image path to the server?
2. If it must be uploaded through input[file], how to set the local image path for it and prevent it from popping up the file selection pop-up box?

There is no such function.
It must pop up to let the user choose.

If you can set the file path of input.file, wouldn’t it mean that you can upload files on the user’s machine at will?
And the user doesn’t know it yet.

Everyone’s computer partition is different, and the location of the pictures must be different. How do you set the default local path?
If you put these things in roughly the same place, you can give a small reminder next to it

The document says it is not allowed:

If allowed, the code writer will upload something privately beyond the user, causing damage to the user.
