You're mixing PHP and JS, you use + to concatenate strings in JavaScript

Change the code to this and it should work:

function JSfunction(assetid) {
    window.location="controller.php?command=delete&assetid=" + assetid;
}

What you are doing now is creating a string and accessing the assetid attribute of that string which is undefined.

you should set window.location to the full URL, not just the relative URL. I.E.

window.location="http://foo.com/controller.php?command=delete&assetid=" + assetid;

BTW, JS uses + to concat, not .

You must include server address, if it is being used locally,it can be denoted by http://localhost/AppName/pages?QueryString.
Concate string with plus sign, dot is used in php script for concatenation.

Actually, most browsers support relative URLs when dealing with window.location
