Topic: How to refresh drag & drop file uploader, after dynamically setting data-default-file attribute by jQuery.
It shows default image by setting static in html, but doesn't show after setting dynamically. here is the code i set to set dynamically:
$('#e-input-file').attr('data-default-file','http://localhost/path/to/img');
Hi,
You can try to change directly the image src attribute. F.e. I added a button below the File Upload :
<button id="fileinputBtn">Change image</button>
And added an onClick listener:
const fileupload = $('#input-file-now-custom-1');
const btn = $('#fileinputBtn');
const fileuploadImg = $('.file-upload-preview-img')[0];
btn.on('click', () => {
fileuploadImg.setAttribute('src', "../img/sample.jpg");
});
Hope it will help you.
Best regards.
I have the same problem, In my edit record form, I want to assign an image to the input file_upload dynamically. And there is no way to refresh the field. Is there a method that does a refresh of the field?. I try to call the method $('#file_upload).file_upload() again and it doesn't work either.
I assign dynamically the attribute $('#file_upload').attr("data-default-file", file_url)

Hi!
The example above is great. I think you have to use another event. When exactly you want to change a file?
Best regards
