[英]Hide(not delete) the checkbox in Blueimp jquery fileupload plugin
[英]how can I reset a blueimp jQuery fileupload plugin?
要點:如何重置 blueimp jQuery fileupload 插件,使其認為尚未上傳任何文件?
我嘗試調用 fileupload('destroy') 然后重新初始化,但這似乎沒有結果(我希望銷毀也會破壞實例的跟蹤)。
僅供參考,我使用的是 v8.8.1——我不想升級,因為一位同事以特定方式更改了一些代碼——呃。 我們計划在預定日期刪除此自定義和升級。 如果我必須更新以解決此問題,請隨時告訴我,因為這完全公平。
頁面第一個文件上傳控件:
<form id="summaryFileUploadForm" action="/api/InvoiceDetailsFile/PostForProcessing" method="POST"
enctype="multipart/form-data" data-bind="disableFileUpload: InvoiceHasSummaryDocument() || (!InvoiceDataIsFilledIn())">
<div class="fileupload-buttonbar">
<div class="fileupload-buttons">
<!-- The fileinput-button span is used to style the file input field as button -->
<span class="fileinput-button">
<span>Add files...</span>
<input id="file" type="file" name="file" />
</span>
<span class="fileupload-loading"></span>
</div>
<!-- The global progress information -->
<div class="fileupload-progress fade" style="display: none">
<!-- The global progress bar -->
<div class="progress" role="progressbar" aria-valuemin="0" aria-valuemax="100"></div>
<!-- The extended global progress information -->
<div class="progress-extended"> </div>
</div>
</div>
<div data-bind="fadeVisible: InvoiceHasSummaryDocument()">
<span class="ui-icon ui-icon-check float-left"></span><span>A summary document has been uploaded.</span>
</div>
<span data-bind="fadeVisible: (!InvoiceDataIsFilledIn())">Please fill out invoice information before uploading a file.</span>
<!-- The table listing the files available for upload/download -->
<table role="presentation">
<tbody class="files" id="Tbody1"></tbody>
</table>
<script id="summaryFileDownloadTemplate" type="text/x-tmpl">
</script>
</form>
頁面上的第二個文件上傳控件:
<form id="detailsFileUploadForm" action="/api/InvoiceDetailsFile/PostForProcessing" method="POST"
enctype="multipart/form-data" data-bind="disableFileUpload: Invoice().DetailItems().length > 0 || (!InvoiceHasSummaryDocument())">
<div class="fileupload-buttonbar">
<div class="fileupload-buttons">
<!-- The fileinput-button span is used to style the file input field as button -->
<span class="fileinput-button">
<span>Add files...</span>
<input id="file" type="file" name="file" />
</span>
<span class="fileupload-loading"></span>
</div>
<!-- The global progress information -->
<div class="fileupload-progress fade" style="display: none">
<!-- The global progress bar -->
<div class="progress" role="progressbar" aria-valuemin="0" aria-valuemax="100"></div>
<!-- The extended global progress information -->
<div class="progress-extended"> </div>
</div>
</div>
<span><strong>NOTE: </strong>Only Excel 2007+ (.xlsx) files are accepted. <a href="<%= ResolveUrl("~/asset/xlsx/Ligado_InvoiceUploadTemplate_Standard.xlsx") %>" target="_blank" id="A1">Need a blank Invoice Upload template?</a><br />
</span>
<span data-bind="fadeVisible: Invoice().DetailItems().length > 0">Invoice details have been uploaded.</span>
<span data-bind="fadeVisible: (!InvoiceHasSummaryDocument())">Please upload a summary file prior to uploading a details file.</span>
<!-- The table listing the files available for upload/download -->
<table role="presentation">
<tbody class="files" id="fileList"></tbody>
</table>
<script id="template-upload" type="text/x-tmpl">
{% for (var i=0, file; file=o.files[i]; i++) { %}
<tr class="template-upload fade" style="display:none">
<td>
<span class="preview"></span>
</td>
<td>
<p class="name">{%=file.name%}</p>
{% if (file.error) { %}
<div><span class="error">Error:</span> {%=file.error%}</div>
{% } %}
</td>
<td>
<p class="size">{%=o.formatFileSize(file.size)%}</p>
{% if (!o.files.error) { %}
<div class="progress" role="progressbar" aria-valuemin="0" aria-valuemax="100" aria-valuenow="0"></div>
{% } %}
</td>
<td>
{% if (!o.files.error && !i && !o.options.autoUpload) { %}
<button class="start">Start</button>
{% } %}
{% if (!i) { %}
<button class="cancel">Cancel</button>
{% } %}
</td>
</tr>
{% } %}
</script>
<script id="template-download" type="text/x-tmpl">
</script>
</form>
我可以使用以下方法清除第一個控件:
$("tbody.files").empty();
大概是因為文件已經在那時上傳了(這很好)。
但是,這不適用於第二種形式。 我試過了:
$("#detailsFileUploadForm").find('.cancel').click();
這會使項目從頁面上消失,但在添加其他文件時它們會重新出現。
我也試過$("#detailsFileUploadForm").fileupload('destroy')
沒有成功(大概是因為它不處理這些功能,更多的是關於綁定。
這個問題的答案比我預期的要簡單得多:
$("table tbody.files").empty();
以前,我認為我做得太多了——嘗試銷毀/重置容器並沒有奏效。
使用這一行代碼,列表似乎重置了,據我所知,一切都運行良好。
這是重置 jquery-fileupload 的理想解決方案
在文件“main.js”中,只需刪除或注釋加載現有文件腳本,如下所示:
if (window.location.hostname === 'blueimp.github.io') {
// Demo settings:
$ ('# fileupload'). fileupload ('option', {
url: '//jquery-file-upload.appspot.com/',
// Enable image resizing, except for Android and Opera,
// which actually support image resizing, but fail to
// send Blob objects via XHR requests:
disableImageResize: /Android(?!.*Chrome)|Opera/
.test (window.navigator.userAgent)
maxFileSize: 999000,
acceptFileTypes: /(\.|\/)(gif|jpe?g|png)$/i
});
// Upload server status check for browsers with CORS support:
if ($ .support.cors) {
$ .Ajax ({
url: '//jquery-file-upload.appspot.com/',
type: 'HEAD'
}). fail (function () {
$ ('<div class = "alert alert-danger" />')
.text ('Upload server currently unavailable -' +
new Date ())
.appendTo ( '# fileupload');
});
}
} else {
// Load existing files:
/ * $ ('# fileupload'). addClass ('fileupload-processing');
$ .Ajax ({
// Uncomment the following to send cross-domain cookies:
// xhrFields: {withCredentials: true},
url: $ ('# fileupload'). fileupload ('option', 'url')
dataType: 'json',
context: $ ('# fileupload') [0]
}). always (function () {
$ (This) .removeClass ( 'fileupload-processing');
}). done (function (result) {
$ (this) .fileupload ('option', 'done')
.call (this, $ .Event ('done'), {result: result});
});
* /}
所以你必須清除或評論“//加載現有文件”部分
我有一個類似的問題,以前上傳的文件包含在下一次上傳中。 就像你掙扎了幾個小時一樣。 直到我嘗試了以下解決方案。 這將清除以前上傳的文件。
在添加函數上,只需添加文件輸入元素的“更改”事件,如下所示:
$('#YourFileUploadElementId').change(function(e) {
data.files.splice(0); // Clear All Existing Files
});
完整示例如下:
$('#YourFileUploadElementId').fileupload({
// Some options
add: function (e, data) {
if(data.files.length > 0) {
// Upload Code Here
}
$('#YourFileUploadElementId').change(function(e) {
data.files.splice(0); // Clear All Existing Files
});
},
// Other Events
});
注意:只需將YourFileUploadElementId更改為您的文件上傳元素 ID。 不要忘記在上傳過程中使用以下內容過濾文件:
if(data.files.length > 0) {
// Upload Code Here
}
這是 jsfiddle.net 上的完整示例
