我想隐藏这个按钮,一旦文件上传,并再次显示它,如果照片被删除。我该怎么做呢?
这是我的HTML:
<form class="fileupload" action="${pageContext.request.contextPath}/someUrl"
method="POST" enctype="multipart/form-data">
<noscript><input type="hidden" name="redirect" value="https://www.somedomain.com"/></noscript>
<input type="hidden" name="type" value="image1">
<div class="row fileupload-buttonbar">
<div class="col-lg-7">
<span class="btn btn-info fileinput-button"><i class="fa fa-plus"></i> Add one photo...
<input type="file" name="image" accept="image/png, image/jpeg">
</span>
<span class="fileupload-process"></span>
</div>
<div class="col-lg-5 fileupload-progress fade">
<div class="progress progress-striped active" role="progressbar"
aria-valuemin="0"
aria-valuemax="100">
<div class="progress-bar progress-bar-success" style="width:0;"></div>
</div>
<div class="progress-extended"> </div>
</div>
</div>
<table role="presentation" class="table table-striped">
<tbody class="files"></tbody>
</table>
</form>
X-TMPL:
<script id="template-upload" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}

{% } %}
{% if (!i) { %}
<button class="btn btn-warning cancel">
<i class="fa fa-trash-o"></i>
<span>Remove Photo</span>

{% } %}

{% } %}

因此并不完全相关。
更新:
按照@ZakariaAcharki的回答,尝试了回调解决方案:
console.log('start')
$('input[name="image"]')
.bind('fileuploadcompleted', function (e, data) {
console.log('hiding')
$('.fileinput-button').hide();
})
.bind('fileuploaddestroyed', function (e, data) {
console.log('showing')
$('.fileinput-button').show();
});
console.log('ended')
not getting fired
更新2:
隐藏似乎可以解决这个问题,但它没有表现出来。
$('.fileupload')
.bind('fileuploaddone', function (e, data) {
console.log('hide');
$('.fileinput-button').hide();
})
.bind('fileuploaddestroy', function (e, data) {
console.log('show');
$('.fileinput-button').show();
});
$(function () {
'use strict';
var uploadPaths = ["fileA", "fileB", "fileC", "fileCA", "fileCB", "fileCC"];
$('.fileupload').each(function (index) {
$(this).fileupload({
dropZone: $(this),
acceptFileTypes: /(\.|\/)(gif|jpe?g|png|doc|docx|pdf|ppt|pptx)$/i, maxFileSize: 10000000,
messages: {
acceptFileTypes: 'Sorry, this file type not allowed. Please make sure the extension of the file is either .gif, .jpg, .jpeg, .png, .doc, .docx, .pdf, .ppt, or .pptx.',
maxFileSize: 'Please make sure your file is under 10 MB in size.'
}
});
$(this).addClass('fileupload-processing');
$.ajax({
url: '/' + uploadPaths[index],
context: $(this)
}).done(function (data) {
$(this).fileupload('option', 'done').call(this, $.Event('done'), {result: {files: data.files}});
$(this).removeClass('fileupload-processing');
});
});
$('#fileupload').fileupload(
'option',
'redirect',
window.location.href.replace(
/\/[^\/]*$/,
'/cors/result.html?%s'
)
);
});
