1.li布局
// 当有文件添加进来时执行，负责view的创建
function addFile( file ) {
var $li = $( '<li id="' + file.id + 'class="gallery-item"">' +
'<p class="title li_p">' + file.name + '</p>' +
'<a class="imgWrap li_p" href="http://s.amazeui.org/media/i/demos/bing-1.jpg""></a>'+
'<p class="progress li_p"><span></span></p>' +
'<p class="zn-uploadphotos-del li_p"><i class="fa fa-times" aria-hidden="true"></i></p>'+
'</li>' ),
$prgress = $li.find('p.progress span'),
$wrap = $li.find( 'a.imgWrap' ),
$info = $('<p class="error"></p>'),2.获取图片的链接
uploader.makeThumb( file, function( error, src ) {
var img;
$wrap.attr('href',src);//获取a的链接3.图片的操作：删除li以及预览
//删除li
$li.on( 'click', '.li_p', function() {
var index = $(this).index(),deg;
switch ( index ) {
case 1:
Code.photoSwipe('a', '#Gallery');
return;
case 3:
uploader.removeFile( file );
return;
}
});
