This is the html code:

<a href="exampleurl" id="a_theme"  onClick="return activate_theme();">Click</a>

This is the jquery code:

function activate_theme(){
  $("#a_theme")).attr("href", "new url");
}

It displays an error :

activate_theme is not defined

1st way:

$(function(){
$("#a_theme").click(
    function(){
        $("#a_theme").attr("href", "new url");
    }
);
});

<a href="#" id="a_theme">Click</a>

2nd way:

function activate_theme(){
    $("#a_theme").attr("href", "new url");
}


<a href="#" id="a_theme" onClick="activate_theme()">Click</a>
