automatic pop-up when click on a radio button

[joshcxa]

As the title suggests

I have 2 options for a user to choose from. If the click the radio button, "yes," I want a pop up window to appear

How do I go about that?

Code: Select all

<form>
<input type="Radio" value="no">No<br>
<input type="Radio" value="yes" onclick="window.open();">Yes
</form>
