我在我的页面中使用下拉区如下(还有其他输入类型的表单文本和选择下拉框):
<form name="somename" method="post" action="/gotoURL" form="role">
// Other form elements here
<div id="droparea">
<div id="actions" class="row">
<div class="col-lg-7">
<!-- The fileinput-button span is used to style the file input field as button -->
<span class="btn btn-success fileinput-button">
<i class="glyphicon glyphicon-plus"></i>
<span>Add files...</span>
</span>
<button type="submit" class="btn btn-primary start">
<i class="glyphicon glyphicon-upload"></i>
<span>Start upload</span>
</button>
<button type="reset" class="btn btn-red cancel">
<i class="glyphicon glyphicon-ban-circle"></i>
<span>Cancel upload</span>
</button>
</div>
<div class="col-lg-5">
<!-- The global file processing state -->
<span class="fileupload-process">
<div id="total-progress" class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0">
<div class="progress-bar progress-bar-success" style="width:0%;" data-dz-uploadprogress></div>
</div>
</span>
</div>
</div>
<div class="table table-striped files" id="previews">
<div id="template" class="file-row">
<!-- This is used as the file preview template -->
<div>
<span class="preview"><img data-dz-thumbnail /></span>
</div>
<div>
<p class="name" data-dz-name></p>
<strong class="error text-danger" data-dz-errormessage></strong>
</div>
<div>
<p class="size" data-dz-size></p>
<div class="progress progress-striped active" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0">
<div class="progress-bar progress-bar-success" style="width:0%;" data-dz-uploadprogress></div>
</div>
</div>
<div>
<button class="btn btn-primary start">
<i class="glyphicon glyphicon-upload"></i>
<span>Start</span>
</button>
<button data-dz-remove class="btn btn-red cancel">
<i class="glyphicon glyphicon-ban-circle"></i>
<span>Cancel</span>
</button>
<button data-dz-remove class="btn btn-red delete">
<i class="glyphicon glyphicon-trash"></i>
<span>Delete</span>
</button>
</div>
</div>
</div> <!-- end action -->
</div> <!-- end droparea -->
然后我有一个提交按钮的形式如下:
<button name="appbut" class="btn btn-primary" type="submit">SEND NOW</button>
这里是问题，dropzone工作得很好，但每次单击dropzone内的按钮时，提交完整的表单，这意味着页面重新加载，任何文本区域中的所有数据，输入框都丢失了。
我有在我的网站上的另一个页面上的下拉区没有包装在一个表单，它的工作很好调用AJAX函数，所以我猜这是与表单有关?
这是我的dropzone ajax代码: // Get the template HTML and remove it from the doument
var previewNode = document.querySelector("#template");
previewNode.id = "";
var previewTemplate = previewNode.parentNode.innerHTML;
previewNode.parentNode.removeChild(previewNode);
var myDropzone = new Dropzone("#droparea", { // Make the whole body a dropzone
url: "/upload-cv2.php", // Set the url
maxFiles: 1,
maxFilesize: 1,
acceptedFiles: 'application/vnd.openxmlformats-officedocument.wordprocessingml.document , application/docx, application/pdf, text/plain, application/msword',
init: function() {
this.on("success", function(file, responseText) {
console.log(responseText);
});
},
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);
};
我不希望每次使用dropzone时表单都提交
变化:
document.querySelector("#actions .start").onclick = function() { myDropzone.enqueueFiles(myDropzone.getFilesWithStatus(Dropzone.ADDED));
};
document.querySelector("#actions .cancel").onclick = function() {
myDropzone.removeAllFiles(true);
};
document.querySelector("#actions .start").onclick = function(e) {
e.preventDefault();
myDropzone.enqueueFiles(myDropzone.getFilesWithStatus(Dropzone.ADDED));
};
document.querySelector("#actions .cancel").onclick = function(e) {
e.preventDefault();
myDropzone.removeAllFiles(true);
};
