    在uniapp中onPullDownRefresh触发多次的解决方法

    微信小程序同样
    由于在uniapp中onPullDownRefresh触发多次的,多次下拉会导致圆圈一直再转,而不消失。

    pages.json文件 enablePullDownRefresh 一定要设置为true,才可以执行刷新的操作。

            {
                "path": "pages/business/demo",
                "style": {
                    "navigationBarTitleText": "测试",
                    "enablePullDownRefresh": true
                }
    
            }
    

    解决方案:启动一个定时器来监控,是否触发了两次,以及是否再刷新。

    isRefresh: false, //模拟网络请求
    isStart: false, //监控二次触发
    定时器 来控制刷新按钮的消失

                border: none;
            }
        }
    </style>
    
    

    最后,你可以使用一些第三方的下拉刷新的插件,或者使用scollview来自定义刷新。
