I am making this addDropzone() function called on a button click which passes a value as mutilple dropzone elements are needed, but only one at time but on different div's so 'val' parameter in function helps define div id's. I am able to run the dropzone element. It also saves the files on the server, but i am not able to get event handler's working.
This is the function that I am using.
Also if anybody could suggest me a way to read server message in event handler
function addDropzone(val){
document.getElementById("div2").innerHTML = '<div class="item" style="width:96%; margin:5px auto; position:relative; height: auto; background-color:lightgray;"><form action="file-upload.php" class="dropzone" id="my-dropzone-'+val+'"></form></div>';
var myDropzone = new Dropzone("div #my-dropzone-"+val);
Dropzone.options.myDropzone = {
paramName: 'file',
method: 'post',
maxFiles: 1,
url: 'file-upload.php',
dictDefaultMessage: "Drag your images",
clickable: false,
maxFilesize: 512,
uploadMultiple: false,
addRemoveLinks: true,
forceFallback:true
};
Dropzone.options.myDropzone = false;
Dropzone.options.myDropzone.enable();
Dropzone.options.myDropzone = {
init: function(){
this.on("maxfilesexceeded", function(file) { alert("File limit 1"); });
this.on("complete", function(file) {alert(serverReponse);});
}
};
}
Didn't know about dropzone, but as I understand the documentation, I would have written it like this :
function addDropzone(val){
var dropZoneId= "my-dropzone-"+val;
// this line has moved-up, and the option is not referenced in the same way
Dropzone.options[dropZoneId] = false;
// proper way of adding new content to div2 without losing event handlers
var div = document.createElement('div');
div.innerHTML = '<div class="item" style="width:96%; margin:5px auto; position:relative; height: auto; background-color:lightgray;"><form action="file-upload.php" class="dropzone" id="'+dropZoneId+'"></form></div>';
document.getElementById("div2").appendChild(div.firstChild);
var myDropzone = new Dropzone("#"+dropZoneId,{
paramName: 'file',
method: 'post',
maxFiles: 1,
url: 'file-upload.php',
dictDefaultMessage: "Drag your images for zone "+val,
clickable: false,
maxFilesize: 512,
uploadMultiple: false,
addRemoveLinks: true,
forceFallback:false,
init: function(){
// from the doc, quick debug
this.on("addedfile", function(file) { alert("added file in zone."+val); });
this.on("maxfilesexceeded", function(file) { alert("File limit 1"); });
this.on("complete", function(file) {alert(serverReponse);});
}
});
}
$(document).ready(function(){
addDropzone(1);
addDropzone(2);
}
);
