If the array is already defined, you can create a json object by looping through the elements of the array which you can then post to the server, but if you are creating the array as for the case above, just create a json object instead as sugested by Paolo Bergantino

    var saveData = Array();
    saveData["a"] = 2;
    saveData["c"] = 1;
    
    //creating a json object
    var jObject={};
    for(i in saveData)
    {
        jObject[i] = saveData[i];
    }

    //Stringify this object and send it to the server
    
    jObject= YAHOO.lang.JSON.stringify(jObject);
    $.ajax({
            type:'post',
           cache:false,
             url:"salvaPreventivo.php",
            data:{jObject:  jObject}
    });
    
    // reading the data at the server
    

    //for jObject= YAHOO.lang.JSON.stringify(jObject); to work,
    //include the follwing files

    //
    //

    //
    //

Hope this helps
