extremetable改装
2023-04-12
在一个项目中用到了extremetable，但是有些的体现形式还不符合业务的需求，所以做了些改动。下面贴出来，供大家参考：
主要增加功能：加入 全选 反选 全不选 的按钮，外观布置改动，增加table的td监听事件。
首先在http://extremecomponents.org/下载eXtremeComponents 1.0.1 的源码
修改org.extremecomponents.table.view.DefaultToolbar如下：

html.td(2).align("right").close();
html.table(2).border("0").cellPadding("0").cellSpacing("1").styleClass(BuilderConstants.TOOLBAR_CSS).close();
html.tr(3).close();

html.tdEnd();
html.td(4).close();
toolbarBuilder.separator();
html.tdEnd();
html.td(4).close();
html.img();
html.src(BuilderUtils.getImage(model, "pageDisplayed"));
html.style("border:0");
html.alt("当前页码");
html.xclose();
toolbarBuilder.pagesDisplayedDroplist();
html.tdEnd();
html.td(4).close();
toolbarBuilder.separator();
html.tdEnd();
html.td(4).close();
html.img();

html.xclose();

html.tdEnd();
if (showExports) {
html.td(4).close();
toolbarBuilder.separator();
html.tdEnd();
}
}
if (showExports) {
Iterator iterator = model.getExportHandler().getExports().iterator();
for (Iterator iter = iterator; iter.hasNext();) {
//html.td(4).close();
html.td(4).close();
html.img();
html.src(BuilderUtils.getImage(model, "ExcelExport"));
//html.style("border:0");
html.alt("导出为Excel");
html.xclose();
Export export = (Export) iter.next();
toolbarBuilder.exportItemAsImage(export);
html.tdEnd();
}
}
html.trEnd(3);
html.tableEnd(2);
html.newline();
html.tabs(2);
html.tdEnd();
}
}
然后修改org.extremecomponents.table.view.HtmlView

public class HtmlView extends AbstractHtmlView {
protected void beforeBodyInternal(TableModel model) {
toolbar(getHtmlBuilder(), getTableModel());
getTableBuilder().tableStart();
getTableBuilder().theadStart();
//statusBar(getHtmlBuilder(), getTableModel());
getTableBuilder().filterRow();

}
protected void toolbar(HtmlBuilder html, TableModel model) {
new DefaultToolbar(html, model).layout();
}
protected void statusBar(HtmlBuilder html, TableModel model) {
new DefaultStatusBar(html, model).layout();
}
}
下面是一个js的公共的函数，因为时间关系，没有融入到代码里面，以后会完善。现在只要include到jsp中就可以了
<%@ page language="java" pageEncoding="gb2312"%>
<%
response.setHeader("Pragma","No-cache");
response.setHeader("Cache-Control","no-cache");
response.setDateHeader("Expires", 0);
