onClientRowSelection for tableView's

Posted on Feb 10, 2005 at 11:09 AM 16 Views

Hi,

I'm working on a portal application which utalises epcf eventing to allow an iView to send messages another iView. Basically a table is displayed in the left iView and, depending which row the user selects, a message containing data from the selected row is sent to the right iView.

I initialy tried to utalise the onClientRowSelection('javascript') feature of the tableView htmlb element (with selectionMode="SINGLESELECT") which is supposed to invoke a javascrip function whose name is supplied as a parameter. However, after spending some time fudging trying to get it working, I was eventually took another route and turned one of the cells into a link.

I was wondering whether anyone else has had any experience using onClientRowSelection and were successful in calling some javascript.

    Thanks Detlev,

    That helps. I was doing something along the lines of:

    <script language="JavaScript">

    function onRowSelect(eventObj){

    alert("Received message from" + eventObj.sourceID + ":" + eventObj.dataObject);

    }

    </script>

    <hbj:tableView

    id="myTableView"

    .....

    width="200"

    onNavigate="onNavigate">

    <%myTableView.setOnClientRowSelection("onRowSelect");%>

    .....

    </hbj:tableView>

    Thinking that the setOnClientRowSelection would invoke the onRowSelect function in the javascript.

    One more question...

    I'd like to use this approach to raise an epcf event i.e.

    myTableView.setOnClientRowSelection("EPCM.raiseEvent(<urn>, <eventName>, <objectData>, <sourseID> )");

    would you by any chance know how to pass data from the selected row to <objectData>?

      Hi Sergio,

      The event object exists, it's not passed, see below.

      > how to pass data from the selected row

      > to <objectData>?

      <%@ taglib uri="tagLib" prefix="hbj" %>
<jsp:useBean id="model" scope="application" class="com.sapportals.htmlb.table.DefaultTableViewModel" />
<%@ page import="com.sapportals.htmlb.TreeNode"%>
<hbj:content id="contentID" >
  <hbj:page title="pageTitle">
    <hbj:form id="formID" >
      <hbj:tableView
        id="myTableView"
        selectionMode="SINGLESELECT"
        model="model"
      >
        <% myTableView.setOnClientRowSelection("showUpTableContent()"); %>
        <% myTableView.setJsObjectNeeded(true); %>
      </hbj:tableView>
    </hbj:form>
  </hbj:page>
  <script language='JavaScript'>
  function showUpTableContent(){
    alert('it was a row ' + htmlbevent.obj.getClickedRow());
  }
  </script>
</hbj:content>

      See https://forums.sdn.sap.com/thread.jspa?threadID=26395 for methods which exist on HTMLB TableView JS object. To retrieve a certain value, set the key column in your table.

      Hope it helps

    Hi Sergio,

    there is no problem at all:

    <%@ taglib uri="tagLib" prefix="hbj" %>
<jsp:useBean id="model" scope="application" class="com.sapportals.htmlb.table.DefaultTableViewModel" />
<%@ page import="com.sapportals.htmlb.TreeNode"%>
<hbj:content id="contentID" >
  <hbj:page title="pageTitle">
    <hbj:form id="formID" >
      <hbj:tableView
        id="myTableView"
        selectionMode="SINGLESELECT"
        model="model"
      >
        <% myTableView.setOnClientRowSelection("alert('hurrah, a row has been selected')"); %>
      </hbj:tableView>
    </hbj:form>   		
  </hbj:page>
</hbj:content>

    ... just works.

    Hope it helps

    Detlev
