ajax - Laravel AJAX - 如何在 console.log 中显示错误

问题描述

我想显示错误，或者想知道为什么这段代码在错误中运行：function()

结果总是运行到错误：函数。我想运行 success:function(data) 并重新加载此页面。

但是控制台没有显示任何关于错误的信息。

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]);
        }
}
