下拉刷新 无法触发回调

我试过这样执行你的代码，是可以打印出1的。或许你应该排查一下你的其他逻辑是否正确

<div id="refreshContainer" class="mui-content mui-scroll-wrapper">   
            <div class="mui-scroll">  
                <!--数据列表-->  
                <ul class="mui-table-view mui-table-view-chevron"></ul>  
            </div>  
        </div>  
        <script src="js/mui.min.js"></script>  
        <script type="text/javascript" charset="utf-8">  
            //mui初始化  
            mui.init();  

            function loadDownData() {  
                console.log(1);  

            }  

            mui.plusReady(function() {  
                var _selfView = plus.webview.currentWebview()  

                var pullRefreshOptions = {  
                    down: {  
                        height: 51,  
                        auto: false,  
                        callback: loadDownData  
                    }  
                };  
                console.log(JSON.stringify(pullRefreshOptions));  
                mui("#refreshContainer").pullRefresh(pullRefreshOptions);  
            });  
        </script>
