javascript - Mobiscroll onBeforeShow，设置值

Question

如何使用 mobiscroll 调用 onBeforeShow 事件？

$('#starttime').mobiscroll('setValue', value).time({
        theme: 'jqm',
        display: 'modal',
        mode: 'clickpick',
        stepMinute: 10,
        onBeforeShow:  
 });

我需要在它显示之前设置时间。如果我尝试在文档准备好时执行此操作，则输入字段尚未准备好值...

编辑

我尝试过:

$('#starttime').mobiscroll('setValue', value).time({
        theme: 'jqm',
        display: 'modal',
        mode: 'clickpick',
        stepMinute: 10,
        onBeforeShow: function(html, inst) {
            start = $('#starttime').val();
            var a = moment();
            var value = a.format('h:mm A');

            }
        });

但随后我收到错误:“值未定义”...

您必须提供回调函数。

$('#starttime').mobiscroll('setValue', value).time({
        theme: 'jqm',
        display: 'modal',
        mode: 'clickpick',
        stepMinute: 10,
        onBeforeShow: function (html, inst) {
            //Gets called before the scroller appears. The function receives the jQuery object containing the generated html and the scroller instance as parameters
        }
 });
