In my web form application, I have used a drop-zone where users will drop files to upload them. At the movement, when I drop a file on the drop-zone, it works fine and I can easily upload that file by clicking the button located down the drop-zone.
However, I want to open the upload file dialog when someone will click on the drop-zone. How can I make the drop-zone clickable so that upload file dialog is shown where I can choose the file to upload. I have searched different techniques but nothing works fine. Is there any way that can help me achieve my goal easily?
My drop-zone HTML is here.
<div id="dZUpload" class="dropzone">
<div class="dz-default dz-message"></div>
</div>
I am looking to achieve this goal with the following jQuery code in document.ready.
var userEmail = $("#hdnFolderPath").val();
var uploadButton = document.querySelector("#upload");
Dropzone.autoDiscover = false;
$("#dZUpload").dropzone({
url: "/ReceiptStorage/Handlers/FileHandler.ashx",
params: {
DestinationPath: userEmail
},
autoProcessQueue: false,
addRemoveLinks: true,
init: function () {
var uploadButton = document.querySelector("#upload");
var dZUpload = this; //closure
dZUpload.on("complete", function (file, response) {
if (file.status === 'success') {
dZUpload.removeFile(file);
LoadFiles($("#hdnFolderPath").val());
}
});
dZUpload.on('error', function (file, response) {
});
uploadButton.addEventListener("click", function () {
if (dZUpload.files.length > 0)
dZUpload.processQueue();
});
}
});
This is the JQuery that is used as the template for every file dropped:
var previewNode = document.querySelector("#template");
previewNode.id = "";
var previewTemplate = previewNode.parentNode.innerHTML;
previewNode.parentNode.removeChild(previewNode);
var myDropzone = new Dropzone(document.body, { // Make the whole body a dropzone
url: "/target-url", // Set the url
thumbnailWidth: 80,
thumbnailHeight: 80,
parallelUploads: 20,
previewTemplate: previewTemplate,
autoQueue: false, // Make sure the files aren't queued until manually added
previewsContainer: "#previews", // Define the container to display the previews
clickable: ".fileinput-button" // Define the element that should be used as click trigger to select files.
});
myDropzone.on("addedfile", function(file) {
// Hookup the start button
file.previewElement.querySelector(".start").onclick = function() { myDropzone.enqueueFile(file); };
});
// Update the total progress bar
myDropzone.on("totaluploadprogress", function(progress) {
document.querySelector("#total-progress .progress-bar").style.width = progress + "%";
});
myDropzone.on("sending", function(file) {
// Show the total progress bar when upload starts
document.querySelector("#total-progress").style.opacity = "1";
// And disable the start button
file.previewElement.querySelector(".start").setAttribute("disabled", "disabled");
});
// Hide the total progress bar when nothing's uploading anymore
myDropzone.on("queuecomplete", function(progress) {
document.querySelector("#total-progress").style.opacity = "0";
});
// Setup the buttons for all transfers
// The "add files" button doesn't need to be setup because the config
// `clickable` has already been specified.
document.querySelector("#actions .start").onclick = function() {
myDropzone.enqueueFiles(myDropzone.getFilesWithStatus(Dropzone.ADDED));
};
document.querySelector("#actions .cancel").onclick = function() {
myDropzone.removeAllFiles(true);
};
