Hyperlinks that only fire if certain conditions are met

Help! Is there any way to have a hyperlink <a href = .......> fire conditionally or only if certain criteria are met. In other words, if the user clicks on the hyperlink, I want to first call a function to make sure that certain conditions are true, and if not, then cancel the navigation to the hyperlink. Unfortunately, I can’t use the “navigate “ function (I think it’s a function anyway) for this purpose which would have worked nicely. Any help would be greatly appreciated.

Yes you can! Set up your hyperlink like this:

Code:

---

  <a href="vbscript: checkValues()">My Link</a>

---

Now create your function to check the values you want to change. After you check the values in your function use document.url:

Code:

---

  document.url = "http://www.yahoo.com"

---

This example was for javascript. Not sure what the function for javascript would be...I'll dig around and see. Document.url may work.
