javascript - Second dropzone doesn't listen to events -


i using dropzonejs file uploading , stumbled upon issue of don't know answer to.

i have 2 dropzones: 1 multiple files , 1 single file. single file version meant replace uploaded file different one, hence allows 1 file uploaded while first 1 allows multiple.

the first dropzone works noticed second dropzone doesn't listen 'sending' event , 'success' event. listen 'error' event , 'accept' event. first dropzone has same events yet works fine dropzone, know how fix this?

the code of interest here below.

dropzones

dropzone.options.requestfileupload = {        init: function(){            this.on('error', function (file, response) {                 console.log("error");             }),            this.on('sending', function (file, xhr, formdata) {                if (file.accepted)                     formdata.append('id', 'uploadfile');             }),            this.on('success', function (file, response) {                 console.log("success!");             })         },         accept: function(file, done){            console.log('file accepted!');         },         acceptedfiles: ".dxf",         previewscontainer: false,         paralleluploads: 5,         createimagethumbnails: false     }      dropzone.options.requestfileedit = {       init: function(){           this.on('error', function (file, response) {              //fired           }),           this.on('sending', function (file, xhr, formdata) {               // not fired               console.log("sending");               if (file.accepted)                  formdata.append('id', 'uploadfile');           }),           this.on('success', function(file, response){               // not fired               console.log('success');            })       },       accept: function(file, done){         //fired       },       maxfiles: 1,       acceptedfiles: ".dxf",       previewscontainer: false,       createimagethumbnails: false     } 
<script src="https://cdnjs.cloudflare.com/ajax/libs/dropzone/5.1.1/min/dropzone.min.js"></script>     <body>        <!-- markup -->        <form data-target="target_i_set_using_js" action="myaction.php" class="dropzone" id="requestfileedit"/>        <!-- other markup -->        <form action="myaction.php" class="dropzone" id="requestfileupload"/>     </body>

i don't know why problem happens, when played code litte bit found init method of 1 of dropzones never called.

this solution dropzones initialized programmatically(docs) , in case can see both dropzones handling events fine(well in post see error handler triggered think work fine in real world scenario)

dropzone.autodiscover = false;    var dzrequestfileedit = new dropzone("div#requestfileedit", {    url: "/file/post",    init: function() {      console.log('initializing requestfileedit ...');      this.on('error', function(file, response) {        console.log("error requestfileedit");      });      this.on('sending', function(file, xhr, formdata) {        console.log('sending requestfileedit ...');        if (file.accepted)          formdata.append('id', 'uploadfile');      });      this.on('success', function(file, response) {        console.log("success!");      });    },    accept: function(file, done) {      console.log('file accepted!');    },    acceptedfiles: ".dxf",    previewscontainer: false,    paralleluploads: 5,    createimagethumbnails: false  });    var dzrequestfileupload = new dropzone("div#requestfileupload", {    url: "/file/post",    init: function() {      console.log('initializing requestfileupload ...');      this.on('error', function(file, response) {        console.log("error requestfileupload");      });      this.on('sending', function(file, xhr, formdata) {        console.log('sending requestfileupload ...');        if (file.accepted)          formdata.append('id', 'uploadfile');      });      this.on('success', function(file, response) {        console.log("success!");      });    },    accept: function(file, done) {      console.log('file accepted!');    },    acceptedfiles: ".dxf",    previewscontainer: false,    paralleluploads: 5,    createimagethumbnails: false  });

let me know if works , if not clear.
