What is the code to have a popup box come up when someone presses a link?

Terry Clark April 13, 2011

I need to insert some code so that when a person clicks on a link a popup box appears to say “you are leaving this website”. Can anybody direct me to the line of code I need and the process.

    Ill add that since you asked about a LINK specifically, just use the above code, but instead of add it to your tag. so something like this:

    Link text

    This can be achieved without forms pretty easily:

    function popup()
    alert("Hello! am a popup!");

    link or img here

    to use link instead of button, use a href tag instead of input tags.

    To create a pop up window:


    To create an alert box:

    function show_alert()
    alert("Hello! I am an alert box!");
