试图使用jquery ajax但无法解析JSON？

Question

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
  }
});

Answer 1

your json string is wrong. it has to be

{"didwork":true,"userid":123}

or

{"didwork":false,"userid":0}

never use = and always use "

Answer 2

Your javascript is wrong..

you need to move the data initialization outside the ajax call..
plus the url needs to be quoted.. ( between ' )

var data = {};
data["username"] = "u";
data["password"] = "p";

this could also be represented with

var data = {'username': 'u', 'password': 'p'};

and the call

$.ajax({
  url: 'https://www.myurl.com/json.php',
  dataType: 'json',
  data: data,
  success: function(json){
    //fill it into div
  }
});

Your json is wrong

should be {"didwork":true,"userid":123}

If the url is to a different site then the one making the call it will fail due to same origin policy
