如何从我的自定义Eclipse插件调用现有的Eclipse对话框？(How to call an existing Eclipse dialog from my custom Eclipse plugin?)

$response['errors'] = $validator->errors()->all();

return response()->json($response, 400);
 
 浏览器需要知道错误状态才能在该ajax函数中触发error方法。 请参阅https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error 
 
 $.ajax({
        url: url,
        type: 'POST',
        data: $writeForm.serialize(),
        error: function(res){ //by using this method, you're assuming that all the logic here is for error handling.
                console.log(res.status, res.errors);
        }

    });

$response['errors'] = $validator->errors()->all();

return response()->json($response, 400);
 
The browser needs to know the error status in order to trigger your error method in that ajax function. See https://en.wikipedia.org/wiki/List_of_HTTP_status_codes#4xx_Client_Error
 
 $.ajax({
        url: url,
        type: 'POST',
        data: $writeForm.serialize(),
        error: function(res){ //by using this method, you're assuming that all the logic here is for error handling.
                console.log(res.status, res.errors);
        }

    });
