GetJSON's data : clarification needed

问题

Given JSON containing:

[
{"myKey":"A","status":0,"score":1.5},{"myKey":"C","status":1,"score":2},
{"myKey":"D","status":0,"score":0.2},{"myKey":"E","status":1,"score":16},
{"myKey":"F","status":0,"score":0.4},{"myKey":"G","status":1,"score":3}
]

Given JS such:

MyJSON = $.getJSON('http://d.codio.com/hugolpz/getJson--/App/data/statusStarter2.json' );

How to get the JSON's content (stringified) into localStorage.data ?

Note: localStorage.data = JSON.stringify(MyJSON); returns {"readyState":1}, which is not my wish. I looked into jQuery.getJSON/, but I'am quite confused by the function (data).

回答1:

getJSON works asynchronously and what it returns is AJAX request object. So use success callback function of getJSON to recieve the data

$.getJSON('http://d.codio.com/hugolpz/getJson--/App/data/statusStarter2.json', function(data) {
  // do JSON.stringify(data) here
});

回答2:

Did you try :

localStorage.setItem('data', JSON.stringify(MyJSON));

and

var JSON = localStorage.getItem('data');

and as ajax is async :

$.getJSON('url', function(MyJSON) {
     localStorage.setItem('data', JSON.stringify(MyJSON));
});
