javascript - express 中在html中使用了ajax然后触发事件，浏览器就死了！！！-PHP中文网问答

function Clearing(){

    var id=[];
    var total = $('.total')
    $('input[name=single]:checkbox').each(function(){
        var self = $(this)
        if(self.is(":checked")){
        id.push(self.data('id'))
        }
    })
    var data = {'id':id,'total':total};
    $.ajax({
            url:'/cart/check',
            type:'post',
            data:data,
            success:function(data,status){
                if(status=='success'){
                 //do_xxxx
                }
            },
            error:function(data,status){
                if(status=='error'){
                //do_xxxx
                }
            }
        })
}

不懂为什么啊，无论ajax中的url指向那个地址，都无法到route的/cart/check上，如果不上ajax就可以正常进行！
