One way is to do this using a URL string. I hope more people respond to this post giving additional ways.

obj.setAction("dblClickAction", function(src){
var row = src.getRowProperty("index");
var count = this.getColumnProperty("count");
var column, result = [];
for (column = 0; column < count; column++)
{result.push(this.getDataProperty("text", row, column)); }
var ID = result[0];
window.open("gotoPage.php?action=selectRow&ID="+ID,null,"height=480,width=640,status=yes,toolbar=no,menubar=no,location=no");
});

First the array is pushed onto the stack...each element. Then the element "0" of array "result" is stored in variable "ID." Then simply concatenate the variable with the URL string.
