错误:: jQuery未被调用

Question

这是我的ajax电话.

 $.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);
    }
});

来自我的示例网址的回复

    "response": [{
        "attributes": {
            "type": "enge",
            "url": "/services/data/v24.0/sobjects/Challenge__c/a0GZ0000005Vvh4MAC"

            "id": "a0O",
            "display_name": "ADR"
        }]
    }

    }],
    "count": 1
}

我正在尝试进行跨域调用并收到错误

jQuery180014405992737595236_1357861668479 was not called

更新

好吧,我试图使用dataType:"json",但在那一点上得到错误

No Transport

Answer 1

这表明网络错误或不返回JSONP响应的终点.

(我猜测我在测试时遇到的DNS查找失败是因为那不是你真正的URL(请使用example.com例如URL,这就是它的用途),如果没有,那就是你的问题).

Answer 2

这是一个不正确的 JSONP 响应。服务器需要处理请求的callback=nameOfCallbackFunction参数GET并将其作为函数包装器提供。

正确的响应应该如下所示：

nameOfCallbackFunction({"yourjson": "here"});
