@login_required
def dbanner():
    banner_id = request.form.get(‘banner_id‘)
    if not banner_id:
        return xjson.json_param_error(message=‘请传入轮播图id！‘)

    banner = BannerModel.query.get(banner_id)
    if not banner:
        return xjson.json_param_error(message=‘没有这个轮播图！‘)

    db.session.delete(banner)
    db.session.commit()
    return xjson.json_success()

前台逻辑

编辑banner.js

$(function () {
    $(".delete-banner-btn").click(function (event) {
        var self = $(this);
        var tr = self.parent().parent();
        var banner_id = tr.attr(‘data-id‘);
        xtalert.alertConfirm({
            "msg":"您确定要删除这个轮播图吗？",
            ‘confirmCallback‘: function () {
                bbsajax.post({
                    ‘url‘: ‘/cms/dbanner/‘,
                    ‘data‘:{
                        ‘banner_id‘: banner_id
                    },
                    ‘success‘: function (data) {
                        if(data[‘code‘] == 200){
                            window.location.reload();
                        }else{
                            xtalert.alertInfo(data[‘message‘]);
                        }
                    }
