的圖像創建佔位符:
<ul id="sortable"></ul>
綁定排序的佔位符:
$("#sortable").sortable();
$("#sortable").disableSelection();
綁定該ondrop功能佔位符:
$('#sortable').on(
'drop',
function(e){
if(e.originalEvent.dataTransfer){
if(e.originalEvent.dataTransfer.files.length) {
e.preventDefault();
e.stopPropagation();
upload(e.originalEvent.dataTransfer.files);
}
}
}
);
最後但並非最不重要的,寫文件API部分:
function upload(files){
for (var i = 0, f; f = files[i]; i++) {
var imageReader = new FileReader();
imageReader.onload = (function(aFile) {
return function(e) {
var li = document.createElement('li');
li.innerHTML = ['<img class="images" src="', e.target.result,'" title="', aFile.name, '"/>'].join('');
$('#sortable').append(li);
};
})(f);
imageReader.readAsDataURL(f);
}
