我从javascript调用api,而api正在返回json.使用以下代码调用json：
document.ready(function(){
$.getJSON(url,function (data) {
console.log(data);
$("#test").text(data);
});
}
});
但它只显示[对象] [对象]到页面.
并且在console.log中,它返回跟随json的无效包括__proto__.

最佳答案
看一下文档：http://api.jquery.com/jquery.getjson/
它说：
The success callback is passed the returned data,which is typically a
JavaScript object or array as defined by the JSON structure and parsed
using the $.parseJSON() method. It is also passed the text status of
the response.
这意味着生成的JSON字符串将自动解析为JavaScript对象.
如果希望结果是JSON格式,可以在结果上使用JSON.stringify()：
function (data) {
jsonData = JSON.stringify(data);
console.log(jsonData);
$("#test").text(jsonData);
});
但是,现在您将解析并字符串化不必要的JSON值.如果您只对字符串表示感兴趣,可以执行以下操作：
$.ajax({
dataType: "text",url: url,success: function (data) {
console.log(data);
$("#test").text(data);
}
});
请记住,$.getJSON只是一个快捷方式：
$.ajax({
dataType: "json",data: data,success: success
});
因此,通过指定dataType：“json”,您告诉jQuery,您期望一个JSON格式的字符串,然后将自动解析.如果指定dataType：“text”,您应该只获取文本表示.
