Question

first was ok. second got error 我在laravel

的javascript页面上使用ajax函数

如果我在功能正常后启动该功能但是当我在短时间内启动功能2或3次时，我得到了错误

"exception": "Symfony\\Component\\HttpKernel\\Exception\\HttpException",
"file": "D:\\AppServ\\www\\come\\vendor\\laravel\\framework\\src\\Illuminate\\Foundation\\Exceptions\\Handler.php",

我搜索错误消息。结果是csfr问题。

但我该如何修复错误？

我已经拥有了

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

问题不是第一次。这是第二次或第三次。

代码

$('.findNews_geography').autocomplete({   
        source: function(request, response) {
            var findtable=$('.findtable_num').val();
            var terms=request.term; 
            console.log("findtable="+findtable+";term="+terms);
            $.ajax({
                headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                },


                url: "findNews_geography",
                dataType: "json",
                type: "post",
                data: {
                    findtable : findtable,
                    term : terms,
                },
                error: function(xhr, ajaxOptions, thrownError) {
                    console.log("findNews_geography ajax error＝"+xhr.responseText);
                    console.log("findNews_geography xhr.status="+xhr.status+";thrownError="+thrownError);
                },
                success: function(data) {
                    console.log("see request="+data);
                    response( $.map( data, function( item ) {
                        return {
                            label: item.place,
                        }

                    }));
                } //success end
            }); //ajax end
        }, //source end
        minLength: 0, 
}); //autocomplete end




 $(".findNews_geography").focus(function () {
         //if (this.value == "") {
       console.log("findNews_geography get focus");
        if($('.findtable_num').val()){
            $(this).autocomplete("search"); 
        }// }; 
  });

$('.findNews_geography').autocomplete({   
        source: function(request, response) {
            var findtable=$('.findtable_num').val();
            var terms=request.term; 
            console.log("findtable="+findtable+";term="+terms);
            $.ajax({
                headers: {
                'X-CSRF-TOKEN': $('meta[name="csrf-token"]').attr('content')
                },


                url: "findNews_geography",
                dataType: "json",
                type: "post",
                data: {
                    findtable : findtable,
                    term : terms,
                    _token: $('meta[name="csrf-token"]').attr('content')  
                },
                error: function(xhr, ajaxOptions, thrownError) {
                    console.log("findNews_geography ajax error＝"+xhr.responseText);
                    console.log("findNews_geography xhr.status="+xhr.status+";thrownError="+thrownError);
                },
                success: function(data) {
                    console.log("see request="+data);
                    response( $.map( data, function( item ) {
                        return {
                            label: item.place,
                        }

                    }));
                } //success end
            }); //ajax end
        }, //source end
        minLength: 0, 
}); //autocomplete end

尝试将ajax request中的csrf令牌作为数据发送

 data: {
          findtable : findtable,
          term : terms,
          _token: $('meta[name="csrf-token"]').attr('content')  
        },

希望这有帮助
