Answer 1

You could use

var change={
    nome2:565655,
    cognome2:8765634
}
if(window.location.search){
    var que = window.location.search.substring(1).split("&"),
        newArr=[];
    for(var i=0;i<que.length;i++){
        var qvar = que[i].split("=");
        if(change[qvar[0]]){
            qvar[1]=change[qvar[0]];
        }
        newArr.push(qvar.join('='));
    }
    window.location.search="?"+newArr.join('&');
}

Edit:

Sorry, the code above works but it’s an eternal loop. Then, use

var change={
    nome2:565655,
    cognome2:8765634
}
if(window.location.search){
    var que = window.location.search.substring(1).split("&"),
        newArr=[],
        changeURL=false;
    for(var i=0;i<que.length;i++){
        var qvar = que[i].split("=");
        if(change[qvar[0]]&&change[qvar[0]]!=qvar[1]){
            console.log('URL changed because of '+change[qvar[0]]+' != '+qvar[1]);
            qvar[1]=change[qvar[0]];
            changeURL=true;
        }
        newArr.push(qvar.join('='));
    }
    if(changeURL){
        window.location.search="?"+newArr.join('&');
    }
}
