touch.on('.content', 'hold', function(ev){
console.log('长按');

touch.off('.content', 'hold');你先试试这样看能不能解绑成功 |

</html>我试了试，能解绑啊，把解绑注释掉，长按事件就生效，不注释的话，长按事件就不会生效 |
并不能解绑啊。。。是我哪里写错了吗 找到原因了，无法解绑是因为没有调用到正确版本的文件。 |

这个项目没人维护了，所以提交代码这么长时间也没人合并过去，所以想解绑的同学就像 @zzhao5 那样自行去拷贝这个版本 v0.2.14 2015-11-10 支持解绑版本 的代码吧 |
