我正在尝试从获取请求中获取 JSON 响应。但是，我收到以下错误： Uncaught SyntaxError: Unexpected token u 。我知道 rails 路线有效，因为我确实在控制台中成功加载了响应。
Ajax 响应应该在复选框更改并被选中时启动。
为什么我从 $.parseJSON 收到此错误？
导轨控制器
def providers
@providers = User.order("last_name ASC, first_name ASC, middle_name ASC").where("provider_flag = ? and inactive_flag = ? and del_flag = ?", true, false, false).select("id, CONCAT(IFNULL(last_name,''), ', ', IFNULL(first_name,''), IFNULL(middle_name,'')) AS full_name");

format.json { render :json => { :providers => @providers.to_json}, :status => :ok }
# format.json { render :json => @providers.to_json }
end
end
Javascript
$('#provider_chk').change(function() {
if($(this).is(":checked")) {
$.ajax({
url: '<%= providers_schedule_index_path %>',
type: 'GET',
dataType: 'json',
data: {
authenticity_token: $('meta[name=csrf-token]').attr('content')
},
success: function(data) {
console.log('loaded successfully.');
var providers = $.parseJSON(data.responseText)['providers'];
providers_count = $(providers).size();
console.log(providers);
console.log(providers_count);
},
error: function(data) {
console.log("An error has occurred!")
}
});
} else {
$('#providers_results').empty();
}
});
JSON 响应
providers: "[{"id":2,"full_name":"Test, User"}]"
Your JSON response should look more like this:
The outermost quotations marks aren't needed.
If you really need the outer quote marks, you need to escape the inner ones.
