Question

我想显示错误，或者想知道为什么此代码运行错误：function（）

结果总是运行到error：function。我要运行成功：功能（数据）并重新加载此页面。

但是控制台没有显示任何有关错误的信息。

======= Ajax ======

function ex_go(r_idx)
{
    if(confirm("Are you sure?") == true)
    {
        $.ajaxSetup({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            }
        });

        $.ajax({
            type:'POST',
            dataType: 'JSON',
            url: "{{ route('change-centerYn') }}",
            data:{r_idx:r_idx},
            success:function(data){
                alert(data.success);
                location.reload();
            },
            error:function(xhr, data){
                console.log(xhr);
            },

    }else{
        return false;
    }
}

======控制器======

public function ex_ok(Request $request)
    {
        if(request()->ajax())
        {
            $r_idx = 'Hello';
            var_dump('<pre>', $r_idx);

            return response()->json(['msg'=>'Updated Successfully', 'success'=>true]);
        }
}

Answer 1

由于您未使用Try和Catch或错误处理，您的控制器将返回200 HTTP标头状态代码，这意味着ajax始终会认为该过程是正确的，并且指出出现了错误，请尝试使用控制器功能中的错误处理，如果在代码处理过程中出现问题，则会引发异常。您可以阅读此link

您可以在下面看到对现有代码的示例代码修改：

public function ex_ok(Request $request)
{
    try
    {
        if(request()->ajax())
        {
            $r_idx = 'Hello';
            var_dump('<pre>', $r_idx);
            return response()->json(['msg'=>'Updated Successfully', 'success'=>true]);
        }
    }
    catch(\Exception $e)
    {
        \Log::error($e); // create a log for error occurrence at storage/log/laravel.log file
        return response()->json($e->getData(), $e->getStatusCode());
    }
}

突然工作了！难以置信的！非常感谢你！你救了我的早晨！

使用try catch

========== AJAX ==========

function ex_go(r_idx)
{
    if(confirm("해당 결제건을 지원센터로 보내시겠습니까?") == true)

        $.ajaxSetup({
            headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
            }
        });

        console.log(r_idx);

        $.ajax({
            type:'POST',
