Perform an event on selecting a prticular row in dojox.grid.DataGrid

问题

I have a code which is working fine and displaying some set of values to me in a grid which is dojox.grid.DataGrid. Now i want to perform some event like when i click on a particular row it will redirect me to a new JSP page. Or will open a window where i can do something. How to do that ? Please help me out. thanks.

The code is ::

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<%@ page import="MyPackage.PopulateTextbox" %>
<%@ page import="java.sql.*" %>

In your onready function, after grid.startup, do the following:

dojo.connect(grid, "onRowClick", grid, function(evt){
    var idx = evt.rowIndex,
        item = this.getItem(idx);

    //  get the ID attr of the selected row
    var value = this.store.getValue(item, "ID");

    //open a dialog or new window or redirect to new JSP

    //to redirect to new jsp, you can set window.location.href to the new url

    //to open a new dialog, i suggest using dijit.dialog 
    //see: http://archive.dojotoolkit.org/nightly/dojotoolkit/dijit/tests/test_Dialog.html

    //to open a new window, use window.open
    //http://www.pageresource.com/jscript/jwinopen.htm
});
