Jmesa

CSS HTML JavaScript jQuery Google

At the bggining,Sorry! I'm spanish an I don't speck english very well, but I want to try some experience in writing.I hop you can understand me.

Today research jmesa colspan header or bottom, I useing jmesa tag:

jmesa provide abstract class AbstractHtmlView ,extends this class and override render() method.

The following is a simple intorduction principle: If you look for jmesa source, you need see the

org.jmesa.facade.tag.TableFacadeTag class, The doTag() method

        View v = tableFacade.getView();
        String html = v.render().toString();
        getJspContext().getOut().print(html);

this code, if you override render(),then httmBuild project append you custom html tag,if you not ovrride redirect jmesa internal out html. if the table is more complicated, rewrite up inside the more difficult.

Ok ..... please the the simple code as following:

public class CreateView extends AbstractHtmlView{

   public Object render() {
        HtmlSnippets snippets = getHtmlSnippets();
        HtmlBuilder html = new HtmlBuilder();
        html.append(snippets.themeStart());
        html.append(snippets.tableStart());
        html.append(snippets.theadStart());
        html.append(snippets.toolbar());
        html.append(snippets.filter());
        html.append(addHeader()); // add header
        html.append(snippets.header());
        html.append(snippets.theadEnd());

        html.append(snippets.tbodyStart());
        html.append(snippets.body());
        html.append(addHtml());    // add footer
        html.append(snippets.tbodyEnd());
        html.append(snippets.footer());
        html.append(snippets.statusBar());
        html.append(snippets.tableEnd());
        html.append(snippets.themeEnd());
        html.append(snippets.initJavascriptLimit());
        return html.toString();
    }

private String addHeader(){
        HtmlBuilder html = new HtmlBuilder();
        html.tr(1).styleClass("odd").close();
         html.td(2).align("center").close().append("Header - A").tdEnd();
         html.td(2).colspan("2").align("center").close().append("Header - B").tdEnd();
         html.trEnd(1);
        return html.toString();
    }
    private String addHtml() {
        HtmlBuilder html = new HtmlBuilder();
        html.tr(1).styleClass("odd").close();
         html.td(2).colspan("2").style("border-right: 1px solid white").close().append("Category").tdEnd();
         html.td(2).colspan("2").close().append("Subcategory").tdEnd();
         html.trEnd(1);
        return html.toString();
    }

}
