简单示例如下:

	</head>
	<body id="dropz">

			<div class="btns sure-btn">保存</div>

		</div>
		
		<script>
			$(function(){
				
				var dropz = new Dropzone("#dropz,.file-upload", {
					url: "#",
					maxFiles: 1,
					maxFilesize: 1,
					acceptedFiles: ".jpg,.jpeg,.png",
					parallelUploads: 1,
					init: function() {
						this.on("addedfile", function(file) {
							setTimeout(function(){
								document.querySelector(‘.logo‘).src = file.dataURL;
							}, 3000);
							
						});
						this.on("success", function(file) {
							console.log("File " + file.name + "uploaded");
						});
					}
				});
	
				$(document).on(‘click‘,‘#logo_upload‘,function(){
					$(‘#dropz‘).click();
				})
				var uploadable = false;
				$(‘#dropz‘).click(function(ev){
					if(!uploadable){
						return false;
					}else{
						uploadable = false;
					}
				})
				$(‘.file-upload‘).click(function(){
					uploadable=true;
					$(‘#dropz‘).click();

			})
		</script>
	</body>
