javascript - 错误 : : jQuery was not called

Question

这是我的 ajax 调用。

 $.ajax({
    type: "GET",
    url: "http://example.com/v1/search?keyword=r",
    dataType: "jsonp",
    crossDomain: true,
    success: function (responseString) {
        alert(responseString);
    },
    error: function (xhr, errorType, exception) {
        var errorMessage = exception || xhr.statusText;
        alert(errorMessage);
    }
});

来 self 的示例 url 的响应

    {
    "response": [{
        "attributes": {
            "type": "enge",
            "url": "/services/data/v24.0/sobjects/Challenge__c/a0GZ0000005Vvh4MAC"
        },
        "name": "Really",
        "end_date": "2013-02-07T15:26:00.000+0000",
        "total": 350.0,
        "registered_members": 0.0,
        "id": "30",
        "type": "Design",
        "id": "a0GZ0000005Vvh4MAC",
        "start_date": "2012-11-19T16:52:00.000+0000",
        "description": "This is my really cool challenge",
        "remaining_days": 28.0,
        "categories__r": [{
            "attributes": {
                "type": "Category__c",
                "url": "/services/data/Category__c/a08Z0000000RNI2IAO"
            },
            "id": "0RNI2IAO",
            "display_name": "Andy"
        }, {
            "attributes": {
                "type": "Category__c",
                "url": "/services/Category__c/a08Z0000000RNI3IAO"
            },
            "id": "a0O",
            "display_name": "ADR"
        }]
    }

    }],
    "count": 1
}

我正在尝试进行跨域调用并出现错误

jQuery180014405992737595236_1357861668479 was not called

更新

好吧，我尝试使用 dataType:"json"但此时出现错误

No Transport

Answer 1

这表明网络错误或端点未返回 JSONP 响应。

(我猜我在测试时遇到的 DNS 查找失败是因为那不是您的真实 URL(请使用 example.com 作为示例 URL，这就是它的用途) 如果不是，那是你的问题)。
