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:  
 });

我需要在它出现之前把时间设定好。如果我试图在document上完成它，输入字段还没有准备好，而值是.

我试过：

$('#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');

            }
        });

但是我得到了一个错误：“值没有定义”.

您必须提供一个回调函数。

$('#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
        }
 });
