我正在使用blueimp和
jquery UI进行文件上传.
我想在上传文件后隐藏此按钮,如果删除照片则再次显示该按钮.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：
<!-- The template to display files available for upload -->
<script id="template-upload" type="text/x-tmpl">
{% for (var i=0,file; file=o.files[i]; i++) { %}
<tr class="template-upload fade">
<td>
<span class="preview"></span>
</td>
<td>
<p class="name">{%=file.name%}</p>
<strong class="error text-danger"></strong>
</td>
<td>
<p class="size">Processing...</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%;"></div></div>
</td>
<td>
{% if (!i && !o.options.autoUpload) { %}
<button class="btn btn-info start" disabled>
<span>Start</span>
<i class="fa fa-caret-right"></i>
</button>
{% } %}
{% if (!i) { %}
<button class="btn btn-warning cancel">
<i class="fa fa-trash-o"></i>
<span>Remove Photo</span>
</button>
{% } %}
</td>
</tr>
{% } %}
</script>
<!-- The template to display files available for download -->
<script id="template-download" type="text/x-tmpl">
{% for (var i=0,file; file=o.files[i]; i++) { %}
<tr class="template-download fade">
<td>
<span class="preview">
{% if (file.thumbnailUrl) { %}
<a href="{%=file.url%}" title="{%=file.name%}" download="{%=file.name%}" data-gallery><img src="{%=file.thumbnailUrl%}"></a>
{% } else { %}
<img src="{%=file.thumbnail_url%}">
{% } %}
</span>
</td>
<td>
<p class="name">
{% if (file.url) { %}
<a href="{%=file.url%}" title="{%=file.name%}" download="{%=file.name%}" {%=file.thumbnailUrl?'data-gallery':''%}>{%=file.name%}</a>
{% } else { %}
<span>{%=file.name%}</span>
{% } %}
</p>
{% if (file.error) { %}
<div><span class="text-danger"><i class="fa fa-exclamation-circle"></i> Error</span> {%=file.error%}</div>
{% } %}
</td>
<td>
<span class="size">{%=o.formatFileSize(file.size)%}</span>
</td>
<td>
{% if (file.deleteUrl) { %}
<button class="btn btn-danger delete" data-type="{%=file.deleteType%}" data-url="{%=file.deleteUrl%}"{% if (file.deleteWithCredentials) { %} data-xhr-fields='{"withCredentials":true}'{% } %}>
<i class="fa fa-trash-o"></i>
<span>Remove Photo</span>
</button>
<input type="checkBox" name="delete" value="1" class="toggle">
{% } else { %}
<button class="btn btn-warning cancel">
<i class="fa fa-trash-o"></i>
<span>Remove Photo</span>
</button>
{% } %}
</td>
</tr>
{% } %}
</script>
我在SO上最近的帖子found并不完全相关.
更新：
尝试了@ZakariaAcharki回答的回调解决方案：
console.log('start')
$('input[name="image"]')
.bind('fileuploadcompleted',function (e,data) {
console.log('hiding')
$('.fileinput-button').hide();
})
.bind('fileuploaddestroyed',data) {
console.log('showing')
$('.fileinput-button').show();
});
console.log('ended')
输出读数：’开始’和’结束’.不知道为什么它是not getting fired.
更新2：
隐藏似乎与此有关,但它没有显示.
$('.fileupload')
.bind('fileuploaddone',data) {
console.log('hide');
$('.fileinput-button').hide();
})
.bind('fileuploaddestroy',data) { //tried fileuploaddestroyed too
console.log('show');
$('.fileinput-button').show();
});
Javascript(除了未更改的tmpl.min.js和jquery文件上传/ UI文件)：

$(function () {
'use strict';
var uploadPaths = ["fileA","fileB","fileC","fileCA","fileCB","fileCC"];
// Initialize the jQuery File Upload widget:
$('.fileupload').each(function (index) {
$(this).fileupload({
dropZone: $(this),acceptFileTypes: /(\.|\/)(gif|jpe?g|png|doc|docx|pdf|ppt|pptx)$/i,maxFileSize: 10000000,// 10 MB
// Error and info 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.'
}
});
// Load existing files:
$(this).addClass('fileupload-processing');
$.ajax({
// Uncomment the following to send cross-domain cookies:
//xhrFields: {withCredentials: true},url: '/' + uploadPaths[index],context: $(this)
}).done(function (data) {
$(this).fileupload('option','done').call(this,$.Event('done'),{result: {files: data.files}});
$(this).removeClass('fileupload-processing');
});
});
// Enable iframe cross-domain access via redirect option:
$('#fileupload').fileupload(
'option','redirect',window.location.href.replace(
/\/[^\/]*$/,'/cors/result.html?%s'
)
);
});
解决方法
你有没有尝试过callbacks fileuploadcompleted和fileuploaddestroyed：
$('input[name="image"]')
.bind('fileuploadcompleted',data) {
$('.fileinput-button').hide();
})
.bind('fileuploaddestroyed',data) {
$('.fileinput-button').show();
});
希望这可以帮助.
