我在这里跑圈子 - 而且我有迹象表明我哪里出错了，但是我无法做到正确，所以希望能在这里得到答案 -
我从放在视图中的js函数发出以下ajax请求：
查看：
$.ajax({
type: 'POST',
url: '/retrieve-location/',
data: {coordinates: { lat: pos.lat, lng: pos.lng}},
dataType: "html",
success: function(data,status,xhr){
console.log('There you go: ' + data);
console.log('Success');
},
error: function(xhr,status,error){
console.log(xhr);
console.log('Somethings gone wrong');
}
});
路线：
match 'retrieve-location/', to: 'after_signup#ajax_geolocation', via: 'post'
after_signup控制器：
def ajax_geolocation
...
respond_to do |format|
format.json { render json: @coordinates, :status => :ok }
end
end
所以一切正常 - 我将DataType从JSON更改为HTML的原因是因为使用JSON它只是在ERROR函数中结束，即使头部设置为OK。
问题
console.log('There you go: ' + data);
输出==＆gt;
There you go: Turbolinks.clearCache()
Turbolinks.visit("http://localhost:3000/en", {"action":"replace"})
但我希望坐标。这只是一个测试电话 - 但我想建立在它上面，我不知道为什么我得到Turbolinks.clearCache（）？
所以我唯一的预感是this - 但我没有使用表格，所以在这里有点迷失。
更新
将数据类型更改为json后，我最终出现在响应的ERROR端，并显示以下错误消息：
SyntaxError: Unexpected token T in JSON at position 0
at JSON.parse (<anonymous>)
at jQuery.parseJSON (jquery.self-bd7ddd3….js?body=1:9012)
at ajaxConvert (jquery.self-bd7ddd3….js?body=1:9336)
at done (jquery.self-bd7ddd3….js?body=1:9790)
at XMLHttpRequest.callback (jquery.self-bd7ddd3….js?body=1:10312)
更新 - 增加了邮递员追踪

答案 0 :(得分：0)
从ajax中试试这个：
url: '/retrieve-location.json' dataType: "json"
