dropzone.js - How to run Dropzone processQueue() when not initiating programmatically? -

im trying initiate dropzone adding class form :

<form class="dropzone ng-pristine ng-valid dz-clickable" id="photodropzonediv" action="/panel/vehicles/3/photos" accept-charset="utf-8" method="post"> 

now dropzone works. next set dropzone not auto process queue :

dropzone.options.photodropzone = {     paramname: "file", // name used transfer file     maxfilesize: 5, // mb     autoprocessqueue: false,     paralleluploads: 500,     acceptedfiles: '.jpg,.jpeg,.jpeg,.jpg,.png,.png',     addremovelinks: true,     init: function(file, done) {         this.on("queuecomplete", function(file) {             this.removeallfiles();         });     } }; 

now when call processqueue :

photodropzone.processqueue(); 

it says uncaught typeerror: photodropzone.processqueue not function. how can fix this?

dropzone.options.addfiles = {     maxfilesize : 4,     paralleluploads : 10,     uploadmultiple: true,         autoprocessqueue : false,     addremovelinks : true,     init: function() {         var submitbutton = document.queryselector("#act-on-upload")         mydropzone = this;         submitbutton.addeventlistener("click", function() {             mydropzone.processqueue();          });         mydropzone.on("addedfile", function(file) {             if (!file.type.match(/image.*/)) {                 if(file.type.match(/application.zip/)){                     mydropzone.emit("thumbnail", file, "path/to/img");                 } else {                     mydropzone.emit("thumbnail", file, "path/to/img");                 }             }         });         mydropzone.on("complete", function(file) {             mydropzone.removefile(file);         });     }, };
