dropzone upload only one file

Question

I am using dropzone.js for my drag-drop file upload solution. I want to upload only one file,if i upload second file the first one should be remove and second one should be uplo

Answer 1

None of these solutions worked for me.

The maxfilesexceeded event is called too late i.e. after an attempt to add the file.

Other solutions using this.removeFile(this.files[0]); resulted in a "Uncaught TypeError: Cannot read property 'removeChild' of null". or an infinite loop.

Solved by -

maxFiles: 2,
init: function () {

    this.on("addedfile", function (file) {
        if (this.files.length > 1) {
            this.files = this.files.slice(1, 2);                        
        }
    });

}

Works when using dz-clickable (file chooser btn) and drag and drop.
