Looking for Information on Popup Windows?

You might want to check out our Popup Windows.

onClick sets a script to run when the user clicks on the link. For example, this link creates an alert box which says Heading Home! when the link is clicked:

this code produces this

<A HREF="mypage.oc.html" onClick="alert('Heading Home!')">My Page</A>
My Page

One of the more useful uses of onClick is creating a popup window which the links targets. This example uses our popup window script (see Popup Window Tutorial).

this code produces this

<A HREF="mypage.popup.html" onClick="return openWindow(this,'mypage')" >My Page</A>
My Page

If onClick returns a value of false then the click is cancelled and the browser doesn't go anywhere. For example, you could check if a user really wanted to go to a URL like this:

this code produces this

<A HREF="deleted.oc.html" onCLick="return confirm('Are you SURE you want to delete this record?')" >Delete It!</A>
Delete It!
