I'm creating an extremely basic script to assist me in one of my google spreadsheets.
I've successfully got a sidebar showing, with a few buttons (which function). However, whenever I click on one of those buttons, it also opens up a new tab, with a URL something like: "https://n-lx3mdv5ls3mdgglsq226llilxd2m4owxy72y3fy-1lu-script.googleusercontent.com/userCodeAppPanel?"
Even if the button is left without any functionality, this still occurs.
Here's an example of the html:
<!DOCTYPE html>
<html>
<head>
<base target="_top">
<link rel="stylesheet" href="https://ssl.gstatic.com/docs/script/css/add-ons1.css">
<!-- The CSS package above applies Google styling to buttons and other elements. -->
<style>
</style>
</head>
<body>
<div class="sidebar">
<form>
<div class="block" id="buttons">
<button id="unindent">Unindent</button>
<button id="indent">Indent</button>
<button id="asdgdgasg">Test</button>
</div>
</form>
</div>
</body>
</html>
