我仍然期待解决这个问题。简单的事情是在输入表单控件中使用自动完成功能，令我惊讶的是，它没有将记录从文本输入中输入。如果我通过浏览器查询结果，则会看到以下结果:
http://localhost:2222/json/redirects/
我确实看到了这个结果:
[{"id":null,"value":"Andorra"},{"id":null,"value":"United Arab Emirates"},{"id":null,"value":"Afghanistan"},{"id":null,"value":"Antigua and Barbuda"},{"id":null,"value":"Anguilla"},{"id":null,"value":"Albania"},{"id":null,"value":"Armenia"},{"id":null,"value":"Netherlands Antilles"},{"id":null,"value":"Angola"},{"id":null,"value":"Antarctica"},
这是 Blade 文件:

<script type="text/javascript">

source: '{!! Url::route('jsonRedirect') !!}',
minlength: 1,
autofocus: true,
select: function(e, ui){
alert(ui);
}
});
</script>
</html>
这是 Controller :
public function SelectLocationPlaces(Request $userAdressRequest)
{
$term = $userAdressRequest->term;
$data = Country::where('name', 'LIKE', '%'.$term.'%')->take(10)->get();
$results = array();
foreach ($data as $key => $value) {
$results[] = ['id'=>$value->id, 'value'=>$value->name];
}
return response()->json($results);
}
这是路线:
Route::get('json/redirects', array('as'=>'jsonRedirect', 'uses'=>'UserAddressController@SelectLocationPlaces'));

亲爱的，请问，自动完成无法正常工作但我仍可以在url上查看json响应的原因可能是什么？
最佳答案
谢谢大家。终于可以了。这是由于传递了错误的URL格式作为来源引起的。所以，我所要做的就是这样:
来自:source: '{!! Url::route('jsonRedirect') !!}',至:'{{ url('json/redirects') }}',
关于json - Laravel 5.1自动完成功能给Symfony fatal error ，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34712517/
