Javascript switch

I have a callback function (onContentLoad) that is parsing some json.  I have a bunch of if/else statements that I'd like to turn into a swtich.
onContentLoad: function (json) {
    //Parse the returned JSON response
    if (json.result == 'success' && json.addremove == 'add') {
 
}
    else if (json.result == 'success' && json.addremove == 'remove') {
 
}
    else if (json.result == 'fail' && json.message == 'action-failed') {
 
}
    else if (json.result == 'fail' && json.message == 'number-exceeded') {
 
}
    else if (json.result == 'fail' && json.message == 'not-logged-in') {
 
}
}

You cannot turn a condition in which you are testing two equalities into a single switch. What you can do is:

//Parse the returned JSON response
if (json.result == 'success')
{
    switch (json.addremove)
    {
    case 'add':
        // Code
        break;
    case 'remove':
        // Code
        break;
    }
}
else if (json.result == 'fail')
{
    switch (json.message)
    {
    case 'action-failed':
        // Code
        break;
    case 'number-exceeded':
        // Code
        break;
    case 'not-logged-in':
        // Code
        break;
    }
}
