我发现使用Jquery Mobile和Phonegap开发android App在android 4中工作正常,但是在旧版本(例如2.2.2)上,可滚动功能中断.因此,我尝试使用iScroll,但是存在冲突的问题,最终我只是决定编写一个Javascript函数来处理它.它曾经可以工作,但是现在坏了.

我仍然是初级开发人员,所以我的代码并不完美,抱歉.但是它应该可以工作,在Android 3中它不会执行该功能,因为滚动已经可以了.在Android 2.9.9或更低版本中可以.而且它应该使div可滚动,但不是,它曾经是,但是后来我以某种方式将其破坏了,我不知道该怎么做.如果有人知道或可以看到它的坏处,我会永远爱你告诉我.谢谢.

编辑我在Eclipse LogCat中也不断出现黄色错误,指出：“在等待WebCore响应以进行落地操作时,缺少拖动”

<div data-role="dialog" id="main" data-theme="a">

<div data-role="page" id="main" data-theme="a">
并删除ID为scrolldroid的div

<div id="scrolldroid" class="scrollstyle"> </div>

<div data-role="footer" class="footermodal">

<div data-role="footer" data-position="fixed" data-tap-toggle="false">
