JSON parseError-以字符串形式获取json

Question

I'm trying to get json data from a service, but getting parseError when I use $.ajax with datatype 'JSONP':

$.ajax({
    url: url,
    dataType: 'JSONP'
})
.error(function(XMLHttpRequest, textStatus, errorThrown) { ... })
.done(function(data) { ... });

If i try it with other datatype than 'JSONP' it returns 404 error.

How can i get just a string instead of parsing json, i believe there is some linebreaks in json that cause parse errors.

Here is the fiddle http://jsfiddle.net/FSEZQ/3/

That's JSON, not JSONP.

For example, this is JSON:

{"key": "value"}

This is JSONP:

callback({"key": "value"})

If the service doesn't provide JSONP, the browser prevents you from getting it (same origin security restrictions).

The way people get around same origin restrictions consist of some server utilization. You can either right code that does this in PHP, or use a service such as AnyOrigin .

Here's an AnyOrigin example.

$.getJSON('http://anyorigin.com/get?url=metservice.com/publicData/tides2MonthAuckland&callback=?', function (data) {
    $('#result1').html(JSON.stringify(data.contents));
}).fail(function (XMLHttpRequest, textStatus, errorThrown) {
    $("#result2").html(textStatus);
});

... and an accompanying fiddle .

Here's an example that shows how this data can be used.
