我正在使用jquery dropzone.js 。要加载我正在使用的表单 mustache像下面这样。但我无法在页面完全加载后初始化拖放区，因为当时没有加载任何表单。是否有一个选项可以在加载后初始化拖放区？
mustache 文件，格式如下:
<div class="col-lg-12">
<div class="ibox float-e-margins">
<div class="ibox-title">
<h5>Dropzone Area</h5>
<div class="ibox-tools">
<a class="collapse-link">
<i class="fa fa-chevron-up"></i>
</a>
<a class="dropdown-toggle" data-toggle="dropdown" href="#">
<i class="fa fa-wrench"></i>
</a>
<ul class="dropdown-menu dropdown-user">
<li><a href="#">Config option 1</a>
</li>
<li><a href="#">Config option 2</a>
</li>
</ul>
<a class="close-link">
<i class="fa fa-times"></i>
</a>
</div>
</div>
<div class="ibox-content">
<form id="my-awesome-dropzone" class="dropzone" action="#">
<div class="dropzone-previews"></div>
<button type="submit" class="btn btn-primary pull-right">Submit this form!</button>
</form>
<div>
<div class="m text-right"><small>DropzoneJS is an open source library that provides drag'n'drop file uploads with image previews: <a href="https://github.com/enyo/dropzone" target="_blank">https://github.com/enyo/dropzone</a></small> </div>
</div>
</div>
</div>
</div>
加载 mustache 并初始化拖放区的函数:
<script>
$( document ).ready(function() {
// get the mustache
loadDropZone();
// HOW CAN I DO THIS AFTER THE DROPZONE FORM IS CREATED?
// init dropzone
Dropzone.options.myAwesomeDropzone = {
autoProcessQueue: false,
uploadMultiple: true,
parallelUploads: 100,
maxFiles: 100,
// Dropzone settings
init: function () {
var myDropzone = this;
this.element.querySelector("button[type=submit]").addEventListener("click", function (e) {
e.preventDefault();
e.stopPropagation();
myDropzone.processQueue();
});
this.on("sendingmultiple", function () {
});
this.on("successmultiple", function (files, response) {
});
this.on("errormultiple", function (files, response) {
});
}
}
});
function loadDropZone() {
$.get(websiteUrl + 'storages/mustache/image-drop-zone.mst', function(template) {
Mustache.parse(template); // speeds up future uses
var rendered = Mustache.render(template);
$('#block-container').append(rendered);
});
}
</script>
最佳答案
您应该以编程方式初始化 dropzone，而不是使用选项和自动发现功能。
应该看起来像这样:
<script>
Dropzone.autoDiscover = false; // This is optional in this case
$( document ).ready(function() {
// get the mustache
loadDropZone();
// Now that the form is loaded you can initialize dropzone by creating an instance
// init dropzone
var myAwesomeDropzone = new Dropzone("form#my-awesome-dropzone", {
autoProcessQueue: false,
uploadMultiple: true,
parallelUploads: 100,
maxFiles: 100,
// Dropzone settings
init: function () {
var myDropzone = this;
this.element.querySelector("button[type=submit]").addEventListener("click", function (e) {
e.preventDefault();
e.stopPropagation();
myDropzone.processQueue();
});
this.on("sendingmultiple", function () {
});
this.on("successmultiple", function (files, response) {
});
this.on("errormultiple", function (files, response) {
});
}
}
});
function loadDropZone() {
$.get(websiteUrl + 'storages/mustache/image-drop-zone.mst', function(template) {
Mustache.parse(template); // speeds up future uses
var rendered = Mustache.render(template);
$('#block-container').append(rendered);
});
}
</script>
