私はこの大きなコードを持っています:
function _buildPlaylist() {
//console.log('_buildPlaylist');
_lastThumbOrientation=null;//important, make thumb holder every time on new playlist
_playlistOpened=false;//reset for bottom this._autoOpenPlaylist selection
var len = _videoProcessData.length, i = 0, thumb, div, _item, active_icon;
//console.log('len = ', len);
if(getDeeplinkData){
dlink = baseURL + strict + firstLevel + '/';
var str_to_filter, tempArr = categoryArr[activeCategory].mediaName;
}
for (i; i < len; i++) {
//console.log(_item.description);
_item = _videoProcessData[i];
//deeplinks
if(useDeeplink && getDeeplinkData){
str_to_filter = filterAllowedChars(_item.deeplink);
//console.log(str_to_filter);
tempArr.push(str_to_filter);
}
playlistLength+=1;
if(outputDeeplinkData){
if(_item.type == 'local'){//aspect ratio always present
if(mp4Support){
loc_path = _item.mp4Path;
}else if(vorbisSupport){
loc_path = _item.ogvPath;
}else if(webmSupport){
if(_item.webmPath)loc_path = _item.webmPath;
}
if(loc_path.lastIndexOf('/')){
loc_name = loc_path.substr(loc_path.lastIndexOf('/')+1);
}else{
loc_name = loc_path;
}
deeplinkData.push({'id': playlistLength, 'name': loc_name, 'type':_item.type ,'video-id': loc_path, 'deeplink': dlink+_item.deeplink});
}else{
deeplinkData.push({'id': playlistLength, 'name': _item.title?_item.title:'', 'type':_item.type ,'video-id': _item.id, 'deeplink': dlink+_item.deeplink});
}
}
div = $('<div/>').addClass('thumbs').attr({'data-id': playlistLength-1, 'data-type': _item.type});
if(thumbHolder)div.appendTo(thumbInnerContainer).bind('click', clickPlaylistItem);
if(_item.type == 'local'){//aspect ratio always present
div.attr({'mp4Path': _item.mp4Path, 'ogvPath': _item.ogvPath, 'webmPath': _item.webmPath?_item.webmPath:'', 'imagePath': _item.imagePath, 'data-aspectRatio': _item.aspectRatio});
}else{
div.attr('path', _item.id);
if(currentObj.ytSizeSet){//if we have width and height, aspect ratio always present
div.attr({'data-width': currentObj.mediaWidth, 'data-height': currentObj.mediaHeight, 'data-aspectRatio': currentObj.aspectRatio});
}
}
if(thumbHolder){
//create thumb
if(_item.thumbnail){
thumb=$(new Image()).addClass('thumb_img').appendTo(div).attr('alt', _item.title?_item.title:'').css({
cursor:'pointer',
opacity:0
}).load(function() {
//console.log($(this))
$(this).stop().animate({ 'opacity':1}, {duration: 500, easing: 'easeOutSine'});//fade in thumb
}).error(function(e) {
//console.log("thumb error " + e);
}).attr('src', _item.thumbnail);
}
//active icon
active_icon = $(new Image()).appendTo(div).css({
position: 'absolute',
display: 'none'
}).load(function() {
//console.log(width,height);
$(this).css({
width: this.width,
height: this.height,
left: 50+'%',
top: 50+'%',
marginLeft: -this.width/2+'px',
marginTop: -this.height/2+'px'
})
}).error(function(e) {
//console.log("error " + e);
}).attr('src', ic_active_thumb);
div.data('active_icon',active_icon);
}
_thumbHolderArr.push(div);//we need to have data to manipulate
}
checkPlaylistProcess();
}
(これは youtube api javascript コードです。それが行うことは、ビデオの alt 属性 title を持つサムネイルを生成することです。
私が欲しいのは、ビデオのタイトルだけを生成することです。サムネイルなし。
コードは次の html を生成します (サムネイル付き)
<div class="thumbInnerContainer" style="top: 0px; left: 0px; width: 3500px;">
<div class="thumbs playlistSelected" data-id="0" data-type="youtube" path="tRe8JfAQmpI" data-width="640" data-height="360" data-aspectratio="2"><img class="thumb_img" alt="Accelerator after effects project file" style="cursor: pointer; opacity: 1;" src="http://i.ytimg.com/vi/tRe8JfAQmpI/hqdefault.jpg"><img style="position: absolute; display: block; width: 37px; height: 37px; left: 50%; top: 50%; margin-left: -18.5px; margin-top: -18.5px;" src="data/icons/active_item.png">
</div>
<div class="thumbs" data-id="1" data-type="youtube" path="QeusWQ4LFmY" data-width="640" data-height="360" data-aspectratio="2"><img class="thumb_img" alt="After Effects Template Platform" style="cursor: pointer; opacity: 1;" src="http://i.ytimg.com/vi/QeusWQ4LFmY/hqdefault.jpg"><img style="position: absolute; display: none; width: 37px; height: 37px; left: 50%; top: 50%; margin-left: -18.5px; margin-top: -18.5px;" src="data/icons/active_item.png">
</div>
<div class="thumbs" data-id="2" data-type="youtube" path="srGUFQwONXc" data-width="640" data-height="360" data-aspectratio="2"><img class="thumb_img" alt="Photo Album - After Effects Template" style="cursor: pointer; opacity: 1;" src="http://i.ytimg.com/vi/srGUFQwONXc/hqdefault.jpg"><img style="position: absolute; display: none; width: 37px; height: 37px; left: 50%; top: 50%; margin-left: -18.5px; margin-top: -18.5px;" src="data/icons/active_item.png">
</div>
</div>
今、これが私が生成したいものです。(画像 alt タイトル属性のみ、サムネイルなし。)
<div class="thumbInnerContainer" style="top: 0px; left: 0px; width: 3500px;">
<div class="thumbs playlistSelected" data-id="0" data-type="youtube" path="tRe8JfAQmpI" data-width="640" data-height="360" data-aspectratio="2">
Accelerator after effects project file
</div>
<div class="thumbs" data-id="1" data-type="youtube" path="QeusWQ4LFmY" data-width="640" data-height="360" data-aspectratio="2">
After Effects Template Platform
</div>
<div class="thumbs" data-id="2" data-type="youtube" path="srGUFQwONXc" data-width="640" data-height="360" data-aspectratio="2">
Photo Album - After Effects Template
</div>
</div>
注: これらの行を見つけて、html がどのように生成されているかを確認してください。
//create thumb
if(_item.thumbnail){
thumb=$(new Image()).addClass('thumb_img').appendTo(div).attr('alt', _item.title?_item.title:'').css({
cursor:'pointer',
opacity:0
}).load(function() {
//console.log($(this))
$(this).stop().animate({ 'opacity':1}, {duration: 500, easing: 'easeOutSine'});//fade in thumb
}).error(function(e) {
//console.log("thumb error " + e);
}).attr('src', _item.thumbnail);
}
サムネイルなしでタイトルのみを生成するように変更するにはどうすればよいですか?
