If you already know the value to append when loading the page then you can add this when the document is ready : If you're using JQuery use this:

});

Otherwise (plain Javascript):

var link = document.getElementById("mylink");
link.setAttribute('href', 'http://www.johndoeslink.com'+'?item=myValue');
