Oracle ADF 实现全选,全不选,多选功能

1 在EO中加入一Boolean类型的字段:isCheck;

2 在VO中加入刚才在EO中的字段;

把VO拖到页面以Table显示，并修改isCheck列的组件为:

 <af:selectBooleanCheckbox value="#{row.isCheck}" id="ot5"/>

同时在刚才的组件下面加入如下代码:

 <f:facet name="header">
             <af:selectBooleanCheckbox label="全选" id="sbc1">
                      <af:clientListener type="valueChange" method="selectAllcheckBox"/>
                       <af:serverListener type="SelectAllCheckBoxClickEvent"method="#{Bean.multipleChoice}"/>

               </af:selectBooleanCheckbox>
 </f:facet>

4 在页面上加入checkBox事件:

 <af:resource type="javascript">

      function selectAllcheckBox(event) {
          var source = event.getSource();
          var isChecked = source.getValue();
          AdfCustomEvent.queue(source, "SelectAllCheckBoxClickEvent",
          {
              params : isChecked
          }, false);
      }
  </af:resource>

5 在Bean的编写全选或全不选代码,首先把table绑定到bean中，在multipleChoice方法中加入如下代码:

   

 public void multipleChoice(ClientEvent clientEvent){
         boolean isSelectAllChecked = (Boolean)clientEvent.getParameters().get("params");
         RichTable rt = get_table();

         for (int i = 0; i < rt.getRowCount(); i++) {
             JUCtrlHierNodeBinding rowData = (JUCtrlHierNodeBinding)rt.getRowData(i);
             Row row = rowData.getRow();
             row.setAttribute("isCheck", isSelectAllChecked);
             AdfFacesContext.getCurrentInstance().addPartialTarget(rt); //刷新table列表
         }
     }

6 处理业务，比如提交到数据库，在提交前需要判断是否有勾选记录，代码如下:

 public boolean isMoreThanOneRowSelected() {
         boolean isMoreThanOne = false;
         DCIteratorBinding dcIterator =ADFUtils.findIterator("VO的迭代器名称");
         ViewObject vo = dcIterator.getViewObject();
         for (int i = 0; i < vo.getEstimatedRowCount(); i++) {
             Row row = dcIterator.getRowAtRangeIndex(i);
             String isSelected = row.getAttribute("isCheck").toString();
             if ((isSelected != null) && Boolean.parseBoolean(isSelected)) {
                 isMoreThanOne = true;
                 break;
             }
         }
         return isMoreThanOne;
     }

7 最终是对勾选的记录编写业务实现,代码如下:

 DCIteratorBinding dcIterator =ADFUtils.findIterator("VO的迭代器名称");
  RowSetIterator rsi =dcIterator.getRowSetIterator().getRowSet()
 　　      .createRowSetIterator("自己定义名称");
  rsi.reset();
  Row selectRow;

  while (rsi.hasNext()) {
      Row selectRow= rsi.next();
      if(selectRow!=null){
      String isSelected = String.valueOf(row.getAttribute("isCheck"));
           if ((isSelected != null) && Boolean.parseBoolean(isSelected)) {
                     //业务处理
            }
        }
    }
