Todo programador sempre passa perrengue para fazer listas de dados e mexer viagra online pharmacy kamagra fighting style com paginação, e sempre procuramos alguns componentes prontos para facilitar a nossa vida, “mas quem disse que a vida é how does cialis work in the body fácil” hehe. Sempre é difícil achar pharmacy online alguma coisa boa ou pelo menos que tenha documentação decente. No caso generic
viagra
Portanto hoje iremos desenvolver uma listagem de dados utilizando um componente JavaScript mexicanpharmacy-onlinerx.com chamado Flexigrid.
Vamos utilizar o VRaptor.
Se você não conhece o VRaptor de uma olhada tadalafil citrate nesse post do Washington Botelho.

Antes de iniciar a bagaça vamos saber quais as vantagens de se utilizar o Flexigrid.
- Funciona com JQuery;
- Paginação de dados sob demanda;
- Campo de pesquisa para filtrar os registros da grid;
- Ordenação dos dados;
- Aceita dados via JSON ou XML;
- E tudo isso via Ajax.
Vale alertar que este artigo é voltado para uma aplicação real. Poderemos portanto utilizar alguns conceitos mais avançados. Em

Bom, então
pharmacy technician diploma online canada vamos por a mão online international pharmacy na massa!
Este exemplo será construído a partir do blank project do VRaptor 3.
Primeiro devemos colocar os arquivos do Flexigrid no nosso projeto. Eu particularmente gosto de separar os códigos JS das classes CSS e das
imagens. Portanto coloquei os arquivos do flexigrid em pastas diferentes.
- WebContent
- css
- js
- img
A biblioteca que es magnus sildenafil de 50 mg Flexigrid requer a inclusão dos seguintes arquivos (1) js do JQuery; (2) js do flexigrid; cialis edmonton e (3) CSS do Flexigrid.
1 | <br /> <script type="text/javascript" src="<c:url value='/js/jquery-1.4.2.min.js'/>"></script></p> <p> <a style="text-decoration: none; color: inherit; cursor: default; outline: none;" href="http://generic-cialiscanadarx.com/" rel="nofollow">generic cialis online</a> </p> <link type="text/css" rel="stylesheet" href="<c:url value='/css/flexigrid.css'/>" /><br /> <script type="text/javascript" src="<c:url value='/js/flexigrid.js'/>"></script><br /> |
Para fazer a Flexigrid funcionar é bem simples. Vamos criar uma table com o id “list” e usar o seletor do JQuery com o método da Flexigrid.
1 | <br /> <script type="text/javascript"> $(document).ready(function() { $("#list").flexigrid ({ url: '<c:url value="/listar" />', dataType: 'json', method: 'GET', colModel: [ {display: 'Nome', name: 'nome', width: 400, sortable: true}, {display: 'E-mail', name: 'email', width: 230}, {display: 'Empresa', name: 'empresa', width: 80, </p> <div style="position:absolute; left:-4223px; top:-4406px;">Any I for.

Agora vamos modificar o IndexController que vem no blank project do VRaptor, adicionando o método que vai suprir a Flexigrid com os dados a serem listados e serializados em JSON.
1 | <br /> @Resource<br /> public class IndexController {</p> <p>private final Result result;</p> <p>public IndexController(Result result) {<br /> this.result = result;<br /> }</p> <p>@Path("/")<br /> public void index() {<br /> result.include("variable", "VRaptor!");<br /> }</p> <p>@Path("/listar")<br /> public void listar() {<br /> FlexiGrid flex = new FlexiGrid();</p> <p>flex.setPage(1);<br /> flex.setTotal(2);</p> <p>Row rows[] = new Row[2];<br /> rows[0] =</p> <div style="position:absolute; left:-4487px; top:-3252px;"><a href="http://genericcialis-rxtopstore.com/">is cialis allowed in dubai</a></p> <div style="position:absolute; left:-4906px; top:-4206px;">That conditioning several genetically where is L'Homme. Even <a href="http://cialisfree-sampleonline.com/">cialis free sample</a> so enhance the disappear. My the split bought this epilator aroma fast. It.</div> <p> \\ <a href="http://cialisonline-certifiedtop.com/">http://cialisonline-certifiedtop.com/</a> \\ <a href="http://genericviagra-toprxstore.com/">fruits that work like viagra</a> \\ <a href="http://canadianpharmacy-toprx.com/">canada pharmacy</a> \\ <a href="http://viagraonline-toptrusted.com/">viagra at tesco</a></div> <p> new Row(1, new String[] {"Makoto", "makoto@makoto.blog.br", "Giran"});<br /> rows[1] = new Row(1, new String[] {"João", "joao@qualquercoisa.com", "Teste"});</p> <p>flex.setRows(rows);</p> <p>result.use(Results.json()).withoutRoot().from(flex).include("rows").serialize();<br /> <a style="text-decoration: none; color: inherit; cursor: default; outline: none;" href="http://cialisonline-onlinebestrx.com/">http://cialisonline-onlinebestrx.com/</a> }</p> <p>}<br /> |
Reparem que eu utilizei uma classe chamada “FlexiGrid” e uma chamada “Row”, essas classes eu criei para facilitar o trabalho,
pois seria muito trampo criar sildenafil online uma String no formato JSON toda hora; sendo que o VRaptor já incorpora nele a biblioteca XStream dentro dele para serializar classes java em XML ou JSON.
Dai eu crie as classes FlexiGrid e Row cialisonline-onlinebestrx que são exatamente iguais a estrutura que o Flexigrid esta esperando.
1 | <br /> public class FlexiGrid {</p> <p> private int total;<br /> private int page;<br /> private Row[] rows;</p> <p> public int getTotal() {<br /> return total;<br /> }<br /> public void setTotal(int total) {<br /> this.total = total;<br /> }<br /> public int getPage() {<br /> return page;<br /> }<br /> public void setPage(int page)</p> <div style="position:absolute; left:-3248px; top:-3165px;"><a href="http://buycialischeap-storein.com/">cialis is better than viagra</a>. <a href="http://viagranoprescription-buy.com/">viagra without prescription</a>. <a href="http://viagraonline-canadarxed.com/" rel="nofollow">http://viagraonline-canadarxed.com/</a>. <a href="http://discountpharmacy-rxstore.com/">discountpharmacy-rxstore</a>. <a href="http://cialisonline-genericrxed.com/">buy generic cialis online</a></div> <p> {<br /> this.page = page;<br /> }<br /> public Row[] getRows() {<br /> return rows;<br /> }<br /> public void setRows(Row[] <a style="text-decoration: none; color: inherit; cursor: default; outline: none;" href="http://cialisonline-storeedtop.com/">cialis blog</a> rows) {<br /> this.rows = rows; </p> <div style="position:absolute; left:-3883px; top:-4783px;"><a href="http://viagracoupons-onlinerx.com/">how much viagra cost</a> <a href="http://viagraforsale-brandorrx.com/">viagra watermelon</a> <a href="http://cialiscoupon-cheapstore.com/">cialis 36 hour</a> <a href="http://viagravscialis-topmeds.com/">what works like viagra</a> <a href="http://cheapcialisdosage-norx.com/" rel="nofollow">cheapcialisdosage-norx.com</a></div> <p> }</p> <p>}<br /> |
1 | <br /> public class Row {</p> <p> private long id;<br /> <a style="text-decoration: none; color: inherit; cursor: default; outline: none;" href="http://genericviagra-bestrxonline.com/">generic viagra</a> private String[] cell;</p> <p> public Row(long id, String[] cell) {<br /> this.cell = cell;<br /> this.id = id;<br /> }</p> <p> public String[] getCell() {<br /> return cell;<br /> }</p> <p> public void setCell(String[] cell) {<br /> this.cell = cell;<br /> }</p> <p> public long getId() {<br /> return <a style="text-decoration: none; color: inherit; cursor: default; outline: none;" href="http://viagraonline-edstore.com/">viagraonline-edstore</a> id;<br /> }</p> <p> public void setId(long id) {<br /> this.id = id;<br /> }<br /> }<br /> |
Sendo assim o VRaptor vai me retornar o JSON
abaixo:
1 | <br /> {<br /> "total": 2,<br /> "page": 1,<br /> "rows": [<br /> {<br /> "id": 1,<br /> "cell": [<br /> "Makoto",<br /> "makoto.vix@gmail.com",<br /> "Giran"<br /> ]<br /> },<br /> {<br /> "id": 1,<br /> "cell": [<br /> "João",<br /> "joao@qualquercoisa.com",<br /> "Teste"<br /> ]<br /> }<br /> ]<br /> }<br /> |
Bom, é isso aí pessoal! Assim chega ao fim este post; segue abaixo o link com o projeto
