I have the same exact need. it would be wonderful if you can please let me know how to do that.

I tried using redirect but that initiate pop-up blocker functionality which mess up my user experience.

Ideally I would like to know when user has clicked the href link so I can track how many times the link is clicked from a particular zul file.

Thank you in advance for you help in this regard

Hello makarchus,

The ZK component reference for a button states the following:

The href property is processed at the client. In other words, the browser will jump to the URL specified in the href property, so your application running at the server has no chance to process it. If you have to process it at the server or you have to decide whether to jump to another URL based on certain condition, you could listen to the onClick event, process it, and then invoke Executions.sendRedirect(String) if it shall jump to another URL.

Reference:

http://books.zkoss.org/wiki/ZKComponentReference/EssentialComponents/Button#HrefandtheonClick_Event

So you should use the onClick event in order to accomplish your task.

Regarding the pop up blocker, are you creating a new tab or redirecting the page in the same tab?

Best Regards,

Darksu

I am using this on iPhone and unless you change the setting for popup blocker, the new window opening does not work. Even after allow pops it prompts for opening a new window.

My ultimate goal is to track how many times people are clicking on one href link. I am unable to find how to track the click and update a count in database that this link was clicked.

Thank you for any help / ways you can recommend.

Hello makarchus,

As a solution for the counter, you could add a url parameter (i.e current date-time using a format yyyymmdd or even just a simple value) and send it with the request.

The window that will open will check, parse the parameter, and then it will update the database table accordingly.
