Accepted answer
Where is the hyperlink located? In the PageLoad itself, check if there is quiz available or not. If the quiz (or its related questions) are not available.. just add the following in the PageLoad event itself..
HyperLinkQ.attrinutes.add("onclick","noquiz();");
And, in the .aspx page (or in external .js file) implement the "noquiz()" function.
In "noquiz" function you wirte the required logic.

Hi Joma,
You are flushing the script after a postback and so you get the alert on a black page. So, you need to write the script code in .aspx file ( or an external .JS file) and call that in the button click (or whereever you need)
You didn't provide us the complete code of the button click. So, I am assuming that you would like to display an alert after executing some server side logic. so, see if you can make an asynchronous call using JQuery to accomplish the functionality.
Thanks,
Prawin
