防止 SetInterval 重叠
我正在使用 jqFancyTransitions.1.8 (http://workshop.rs/projects/jqfancytransitions/) 并启用了导航。
我遇到的问题是,如果我垃圾点击图像(或者只是点击太早或太晚),效果会变得疯狂(特别是在窗帘效果上) - 这是因为 javascript 间隔重叠并且偏移量超出了同步。
我尝试编辑脚本以在转换未运行时隐藏并重新显示导航,但我无法使其正常工作,并且导航会以不同的时间间隔重新显示,也许我将代码放在了错误的位置。
谁能帮我插入 $('#ft-buttons-slideshowHolder').show() && $('#ft-buttons-slideshowHolder').hide() 在正确的位置才能使其正常工作?
我还想知道是否有人使用此工具遇到了同样的问题并已经构建了任何黑客或修复程序,或者是否有人能够为我提供快速修复所需的帮助!
谢谢社区!!
(不是我的代码,只是为了方便帮助而美化)...

I am using jqFancyTransitions.1.8 (http://workshop.rs/projects/jqfancytransitions/) and have the navigation enabled.
The problem I have is that if I spam click through the images (or simply click to early or too late), the effect goes crazy (especially on the curtain effect) - this is because the javascript intervals overlap and the offsets just go out of sync.
I have tried to edit the script to hide and reshow the navigation when a transition is not running, but I couldnt get this working properly, and the navigation would reshow at different intervals, maybe I was putting the code in the wrong place.
Can anyone help me insert $('#ft-buttons-slideshowHolder').show() && $('#ft-buttons-slideshowHolder').hide() in the right place to get this to work?
I was also wondering if anyone using this has had the same problem and constructed any hacks or fixes already, or if anyone is able to provide me with the assistance I require to make a quick fix happen!
Thank you SO community!!

我同意马库斯的观点——代码急需彻底修改,我将寻找替代方案。我向任何在同一库中遇到相同问题的人提供同样的建议,因为这个版本并不完全“稳定”
I agree with Marcus - the code is in dire need of an overhaul and I will be looking for an alternative. I advise the same to anyone that comes across the same problem with the same library as this version is not exactly "stable"
