This should be simple, but I cannot find the answer...

I have a data element in a report which I want to be a URL hyperlink only if the data starts with the text "AB". As a first step, I need help with setting the hyperlink to a URL via script -- then I can set it to "none" or to a specific URL with an if/else, based on the data element's value.

I have read Jason W's article here:
eclipse.org/birt/phoenix/deploy/reportScripting.php

... specifically, the following text seems to be exactly what I need:
Modifying Hyperlinks
The hyperlink for a data element can be modified in the onPrepare by using code similar to:
this.getAction().URI = "'http(COLON-SLASH-SLASH)www.google.com'";
Notice the single quotes within the double quotes.

However, I have the following in the onPrepare script of my report's data element, and it does not work:
this.helpText = "Click here for Google";
this.getAction().URI = "'http(COLON-SLASH-SLASH)www.google.com'";

The helpText works (it pops up when I hover over the element), but the data item is not a clickable URL when I "view report as HTML" in BIRT Designer.

I am using BIRT Report Designer 2.2.1.

Any help / suggestions will be much appreciated.

Note the (COLON-SLASH-SLASH) in above links should be replaced with :// -- I had to do this because this forum says "You cannot use links until you have posted more than 5 messages".

Thank you,
Lawrence

If you want the hyperlink to be dynamic, meaning it changes for every
instance of the data item, you need to use an onCreate event. For example:

if( this.getValue() > 40 ){
var myaction =this.createAction();
myaction.setHyperlink("http://www.google.com", "_blank");
this.action = myaction;
}

I am attaching a 2.2.1 example.
