How to change thumbnail src value in Dropzone.js?

Question

I'm using Dropzone.js with jQuery to upload files to the server. Afer file uploaded I'm generating a "server-side" filename with the current url.

$('.dropzone').dropzone({
    init: function() {
        this.on('success', function(file) {
            var newname = generateServersideFilename(file.name); // this is my function
            // here I need a help to find the thumbnail <img> to set the 'src' attribute
        }
    }
});

How can I find the current thumbnail img to set the src attribute?

Answer 1

This worked for me:

$('.dropzone').dropzone({
    init: function() {
        this.on('success', function(file) {
            var newname = generateServersideFilename(file.name); // this is my function
            // changing src of preview element
            file.previewElement.querySelector("img").src = newname;
        }
    }
});

dropzonejs have few examples of using file.previewElement
