js代码

$('.form-horizontal').submit(function(event) {
    var data = $(this).serialize();
    $.ajax({
        type:"post",
        url:"/authrule/add",
        async:true,
        data:data,
        success:function(res){
            if(res.code == 1){
                Notify(res.msg, 'top-right', '5000', 'success', 'fa-check', true);
                return false;
            }else{
                Notify(res.msg, 'top-right', '5000', 'danger', 'fa-times', true);
                return false;
            }
        }
    })
    return false;
})

post提交正常,但是提交后自动请求了一个get,请问哪错了吗?
