我試圖顯示縮略圖圖像時，他們上傳到服務器上的輸入字段旁邊。問題是我的功能是在圖像上傳之前嘗試顯示圖像。上傳的圖像只顯示一些縮略圖
我認爲這與在服務器上存在縮略圖之前調用縮略圖有關。有沒有辦法改變我的代碼，以便在完成上傳到服務器之後調用要顯示的圖像？
這裏是我的HTML
<div class="module">
<div class="moduleTitle">Upload Photos</div>
<form id="upload" method="post" action="actions/upload.php" enctype="multipart/form-data">
<input type="hidden" name="username" value="<?php echo $username; ?>" id="username">
<div id="drop">
Drop Here
<a>Browse</a>
<input type="file" name="upl" multiple />
</div>
<ul>
<!-- The file uploads will be shown here -->
</ul>
</form>
</div>
<div class="module">
<div class="moduleTitle">Add Tags to Images</div>
<form onSubmit="addTags();return false;" id="tagAddForm">
<ul>
<!-- Ths is where the tag inputs will appear -->
</ul>
<input type="submit" name="login" value="Add Tags" class="submit" id="login"/>
</form>
</div>
這裏是我的JS
$(function(){
var ul = $('#upload ul');
;;
$('#drop a').click(function(){
// Simulate a click on the file input button
// to show the file browser dialog
$(this).parent().find('input').click();
});
// Initialize the jQuery File Upload plugin
$('#upload').fileupload({
// This element will accept file drag/drop uploading
dropZone: $('#drop'),
// This function is called when a file is added to the queue;
// either via the browse button, or via drag/drop:
add: function (e, data) {
var tpl = $('<li class="working uploaded"><input type="text" value="0" data-width="48" data-height="48"'+
' data-fgColor="#0788a5" data-readOnly="1" data-bgColor="#3e4043" /><p></p><span></span></li>');
// Append the file name and file size
tpl.find('p').text(data.files[0].name);
//Create an empty container
var path = "artistpit/users/" + $("#username").val() + "/";
var $elems = $();
//Cycle thru the files
$.each(data.files, function(idx, file) {
//Create an input with attrsd
var $input = $("<input/>", {
'type': 'text',
'placeholder': 'separate tags with commas',
'name': file["name"]
});
//Create list element with an image thumb + append input
var $li = $("<li/>", {
html: "<img src='" + path + file["name"] + "' width='50' />"
}).append($input);
//Populate the container with the list item
$elems = $elems.add($li);
});
//Append all list items
$("#tagAddForm > UL").append($elems);
// Add the HTML to the UL element
data.context = tpl.appendTo(ul);
// Initialize the knob plugin
tpl.find('input').knob();
// Listen for clicks on the cancel icon
tpl.find('span').click(function(){
if(tpl.hasClass('working')){
jqXHR.abort();
}
tpl.fadeOut(function(){
tpl.remove();
});
});
// Automatically upload the file once it is added to the queue
var jqXHR = data.submit();
},
progress: function(e, data){
// Calculate the completion percentage of the upload
var progress = parseInt(data.loaded/data.total * 100, 10);
// Update the hidden input field and trigger a change
// so that the jQuery knob plugin knows to update the dial
data.context.find('input').val(progress).change();
if(progress == 100){
data.context.removeClass('working');
}
},
fail:function(e, data){
// Something has gone wrong!
data.context.addClass('error');
}
});
// Prevent the default action when a file is dropped on the window
$(document).on('drop dragover', function (e) {
e.preventDefault();
});
// Helper function that formats the file sizes
function formatFileSize(bytes) {
if (typeof bytes !== 'number') {
return '';
}
if (bytes >= 1000000000) {
return (bytes/1000000000).toFixed(2) + ' GB';
}
if (bytes >= 1000000) {
return (bytes/1000000).toFixed(2) + ' MB';
}
return (bytes/1000).toFixed(2) + ' KB';
}
});
