documentum中用js获取datagrid中的数据

documentum中用js获取datagrid中的数据，js操作datagrid

 

以下代码是js得到datagrid，且控制第一行被选中，并且得到选中行的第一列属性

 

//得到datagrid对象，WorkflowInfor为当前component对应的类名，mygrid为datagrid的name属性值

 

 var dg = wdk.dom.get('WorkflowInfor_mygrid_0').datagrid;

 

//获取行数
     var count = dg.getRowCount();
     if(count>0){

 

//选中第1行
      dg.highlight(0,true);
   

//获得当前选中行的第一列属性值，返回值为数组
   var workflowId = dg.data.getItemActionArgs(0, 'select');   
   if(id!=workflowId[0]){
    url = "<%=Form.makeUrl(request,"/component/workflow_view_component?objectId=")%>" + "<%=objectId%>&workflowId=" + workflowId[0];

 

//其它操作
    changeFrameLocationInFrameset(parent, "workflow_view", url);
   }
   id = workflowId[0];
  }

 

 

 

有时候我们需要当单击datagrid的某行的时候，触发js方法做一些操作

 

 

<dmf:datagridRow name='attachcolumns' height='24'
        cssclass='defaultDatagridRowAltStyle'
        altclass="defaultDatagridRowStyle">
        <dmf:datagridRowTd scope='row' valign="middle"
         cssclass='doclistfilenamedatagrid' width="250">
         <dmf:stringlengthformatter maxlen='16' wrapped='true'
          postfix='...'>
          <dmf:datagridRowEvent eventname="select"
           eventhandler="onViewAttachment" runatclient="true">
           <dmf:image datafield="icon" />
           <dmf:link onclick='onViewAttachment' name='objectLink'
            runatclient='true' datafield='workflow_name'>
            <dmf:argument name='objectId' datafield='workflow_id' />
           </dmf:link>
          </dmf:datagridRowEvent>
         </dmf:stringlengthformatter>
        </dmf:datagridRowTd>
       </dmf:datagridRow>

 

 

function onViewAttachment(event){
     var url="";
  if (event.count == 1) {
   //alert(event.startIndex+"    "+event.type);
   var workflowId = event.datagrid.data.getItemActionArgs(event.startIndex, event.type);   
   if(id!=workflowId[0]){
    url = "<%=Form.makeUrl(request,"/component/workflow_view_component?objectId=")%>" + "<%=objectId%>&workflowId=" + workflowId[0];
    changeFrameLocationInFrameset(parent, "workflow_view", url);
   }
   id = workflowId[0];
  }
 }
