I'm trying to load some data via jQuery.getJSON() but it does not work:

here is my JSON:

```
{didwork=true,userid=123}

```

or it is

```
{didwork=false,userid=0}

```

here is my Javascript:

```
$.ajax({
  data["username"] = "u"
  data["password"] = "p";
  url: https://www.myurl.com/json.php,
  dataType: 'json',
  data: data,
  success: function(json){
    //fill it into div
  }
});

```
