[教學][語法]blogger：階層式標籤

如果想令ｂｌｏｇｇｅｒ的標籤有階層式縮放功能，例如：

可參考Gormit的方法：

Blogger 文章分類工具 (第二版)

Step １：

打開版面配置,加入標籤這個小工具, 一定要設定為用按字母排序

顯示設定不重要等下一步的script只會以清單表現

Step ２：

選擇"修改HTML" 並鉤選"展開小裝置範本"
找到步驟一新加的小工具 找像下列的字串
 <b:widget id="Label2" locked="false" title="標籤" type="Label"> 一直到 </b:widget>

Step ３：
將上述範圍內的內容改為:
<b:widget id='Label3' locked='false' title='文章分類(v2)' type='Label'> <b:includable id='main'> <b:if cond='data:title'> <h2><data:title/></h2> </b:if> <div expr:class='"widget-content " + data:display + "-label-widget-content"'> <script> var label_tree= new Object(); function tn(tag) { return tag.substring(1,tag.length-1); } function build_node(tree,idx,cnt) { if(!tree[idx[0]]){ tree[idx[0]]=new Object(); tree[idx[0]]['_cnt']=0; tree[idx[0]]['_item']=new Array(); } tree[idx[0]]['_cnt'] = parseInt(tree[idx[0]]['_cnt']) + parseInt(cnt); if(idx.length==1){ return tree[idx[0]]; } return build_node(tree[idx[0]],idx.slice(1),cnt); } function add_label(_name,_cnt,_url,_dir) { var e1 = new RegExp("\\[(.+?)\\]","g"); var e = new RegExp("\\[(.+)\\]","g"); var m = _name.match(e); var tag = _name; var obj=new Object(); obj['tag']=_name; obj['cnt']=_cnt; obj['dir']=_dir; obj['url']=_url; if(m){ obj['tag']= _name.substring(m[0].length,_name.length); var m1 = _name.match(e1); if(m1){ node=build_node(label_tree,m1,_cnt); if(node){ node['_item'].push(obj); } } } else{ if(!label_tree['_item']){ label_tree['_item']=new Array(); } label_tree['_item'].push(obj); } } function menu_exp(id) { var ul=document.getElementById("ul_"+id); var li=document.getElementById("li_"+id); if (ul.style.display=="none"){ ul.style.display="block" li.style.backgroundImage="url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhyxHhIYEEkaiFL04Q0Des0Jqy2tHIYnWI19qqd_YQzEFwSMbvTC87O_XZht-_zhKwXKcE4KkJi43tQZHmlfzYOuQSkRtxLkcsrOfPwOMt6C5Is6vw8y_1xibFtlTO22Wds9gzA4wmYjMA/)" } else { ul.style.display="none" li.style.backgroundImage="url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEio365HkIr3BYPobe-n3h97H_Re7-zeKC9OtRZ3NRS4l4psFHYx1Twm9ufseCxGYDrVjiq4TDVyhLMGn_jl_5xubg9qcpU9tQ5j-K3pLYXrlP9Rfzc7pp7DMWflyXhdS6EfudHwmXY6aFw/)" } } function draw_obj(obj) { document.write("<li style='padding-left: 0px>'"); document.write("<img src='https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhUxhxG03vldCofkFRW-QltLABcky9ipn3U9OCXb4uWQQDi_NB_Hu86_TBD3WqoU3ch_RvCruV3iT3KtqHX_kvGF3_6LsPg41J7yR29Jk-CtGmeIPenDWYFIYkS3rqHZFbbUDE2PQT4lgc/s1600/icon-yellow-bullet.png' /><a dir='"+obj['dir']+"' href='"+obj['url']+"'>"+obj['tag']+"</a>"); document.write("<span dir='"+obj['dir']+"'>("+obj['cnt']+")</span>"); document.write("</li>\n"); } function draw_tree(tree) { for(var tag in tree){ if(tag!='_item'&& tag!='_cnt'){ var rid = Math.random(); document.write("<li class=submenu id=li_"+rid+" onclick=menu_exp('"+rid+"'); style='font-weight:bold;padding-left: 20px;background: url(https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEio365HkIr3BYPobe-n3h97H_Re7-zeKC9OtRZ3NRS4l4psFHYx1Twm9ufseCxGYDrVjiq4TDVyhLMGn_jl_5xubg9qcpU9tQ5j-K3pLYXrlP9Rfzc7pp7DMWflyXhdS6EfudHwmXY6aFw/) no-repeat left 0px;cursor: pointer'>"); document.write(tn(tag)); document.write("("+tree[tag]['_cnt']+")"); document.write("</li>"); document.write("<ul id=ul_"+rid+" style='display:none;padding-left: 20px'>"); draw_tree(tree[tag]); document.write("</ul>\n"); } } if(tree['_item']){ for(var i=0;i < tree['_item'].length;i++){ draw_obj(tree['_item'][i]); } } } </script> <b:loop values='data:labels' var='label'> <script> add_label('<data:label.name/>','<data:label.count/>','<data:label.url/>','<data:blog.languageDirection/>'); </script> </b:loop> <ul> <script> draw_tree(label_tree); </script> </ul> <b:include name='quickedit'/> </div> </b:includable> </b:widget>

Step ４：

使用　[分類1][分類2]標籤　的格式來定義標籤即可（例子如下）

然後大功告成！｡:.ﾟヽ(*´∀`)ﾉﾟ.:｡
