jQuery 应用程序问题。这是一个小故障还是不正确的编码?
我遇到了一个相当简单但恼人的问题。
我正在尝试创建一种“选择日期”日历,但采用轮播风格,就像那些图像滑块一样。
用户单击日期后,
应滚动到中心,并更改其 CSS、设置动画。我找到了这个图像滑块,这正是我所需要的: http://opiefoto.com/articles/photoslider(底部演示)
我想做的就是去掉大图像和播放/暂停按钮,并稍微更改一下CSS,到目前为止,我已经成功了这样做: http://chadascinco.net/photoslider/
那些对故障有敏锐洞察力的人可能已经注意到了那......当您单击一个缩略图,然后单击另一个缩略图时,前一个保持其旧高度,但是,您仍然可以看到它“轻弹”,就像有什么东西迫使它回到原来的高度。
这就是我的问题。
如果您使用 firebug 或类似的东西进行检查,您会注意到高度变为 66px,但之后又回到 121px。
现在,对于一些奇怪的事情,如果我去掉“顶部”值的变化,高度就完美了。它完全按照我的需要生长和回归。但如果我把它放回去……该死,我们就这样了,高度故障。
我尝试通过电子邮件联系作者,但三天过去了,我还没有收到回复。
在这里我请求大家分享知识,我是 JavaScript 和 jQuery 的新手,所以这可能也是我的代码中的问题。我只是尝试使用基本的编程逻辑。
负责的 js 是“photoslider.js”,如果您检查“FELIX Note”,您会在我进行任何更改的每个部分中找到注释。其他评论均来自作者原创。
过渡有效的行是从 265 到 287。
如果我说的任何内容令人困惑,我很高兴能更准确。
如果你们还需要查看原始代码,可以在这里查看:http://chadascinco.net/photoslideroriginal
另外,如果您知道任何其他可以满足我需要的应用程序,我将非常感激。
再次感谢大家。
品牌新闻编辑:我发现了一个有趣的事实:如果你检查我提到的行,你会注意到 3 个动画调用。
无论您做什么,如果您将相同的 CSS 属性放在活动和非活动 div 的 SECOND 调用上,它就会闪烁并导致此故障。我尝试更改为“背景颜色”而不是高度,从黑色更改为白色并向后更改。
发生的事情是这样的:当我加载页面时,只有活动页面是黑色的。好的。但是当我点击另一个时,这个变成黑色,而上一个试图变成白色,但被迫再次变成黑色。我想知道,为什么只有第二个电话?如果这是第一个,或者最后一个,或者每一个,好吧,但是……只有第二个?诡异的。
I've got into a rather simple, yet annoying problem.
I'm trying to create a kind of "pick a date" calendar, but in carousel style, just like those image sliders.
Once the user clicks on a date, the <div>
should scroll to the center, and have its CSS changed, animated.
I've found this image slider which is exactly what I need: http://opiefoto.com/articles/photoslider (Demo at the bottom)
All I wanted to do, is, take off the big image and the play / pause button, and change the CSS a little bit, so far, I've managed to do THIS: http://chadascinco.net/photoslider/
People with keen eye for glitches probably already had noticed that... when you click on a thumbnail, and then click on another, the previous one keeps its old height, still, you can see it "flicking" like something is forcing it back to that height.
And that's my problem.
If you check using firebug or something similar, you'll notice that the height GOES to 66px, but goes back to 121px just after that.
And now, for something weird, if I take off the "top" value change, the height works perfectly. It grows and go back exactly as I need. But if I put it back... damn, there we go, height glitch.
I've tried to contact the author through email, but it has been 3 days and I've gotten no reply back.
And here I ask ya all for a share of knowledge, I'm a very newcomer with JavaScript and jQuery, so it might be also a problem in my code. I just tried to use basic programming logic.
The js responsible is "photoslider.js" and if you check for "FELIX Note", you'll find notes in every single part where i made any changes. Any other comments are original from the author.
The lines where the transition works are from 265 to 287.
If anything I said is confusing, I'd be glad to be more accurate.
If you guys also need to check the original code, you can check it here: http://chadascinco.net/photoslideroriginal
Also, if you know any other application that works like what I need, I'd be most thankful to know.
Thank you all once again.
BRAND NEWS EDIT: I've found one interesting fact: if you check the lines i mentioned, you'll notice 3 animation calls.
No matter what you do, if you put the same CSS property on the SECOND call for both active and inactive divs, it'll flick and cause this glitch. I've tried changed to "background-color" instead of height, changing from black to white and backwards.
Here's what happened: When i load the page, only the active one is black. Good. But when i click another, this one becomes black, and the PREVIOUS one tries to become white, but is forced to become black again. i wonder, why only the Second call? If it was the first, or the last, or every of them, alright, but... only the second? Weird.

嘿,我遇到问题了。问题是这个库并不期望您一次使用多个动画。初始化动画的函数 SKEL.EFFECTS.Slide.animate 在动画对象中创建一个名为 skel_animate_id 的字段,它实际上是为执行动画而设置的计时器的 id。
由于这个库不希望一次有多个动画,所以当您创建一个新动画时,它只会执行
element.skel_animate_id = setInterval(.....
),如果您关注我,您就会发现会意识到之前skel_aimate_id
上的任何内容(即库对任何先前动画计时器的唯一引用)在该分配之后都会丢失。现在,有一个由计时器调用的步骤函数,位于 中。负责识别动画何时结束,并停止计时器本身,但它是通过调用clearInterval(element.skel_animate_id);来实现的,这显然只会清除与最后一个动画属性相关的计时器。
长话短说,当您调用第二个属性的动画时(在第一个属性结束之前),您会留下一个打开的计时器,该计时器会继续“动画”第一个属性(即将其设置为最终值)
。编辑: 修复的现场演示。
有罪片段
行[488 -531]
可能的解决方案
我将
skel_animate_ids
作为数组,并存储每个间隔以及对动画属性的引用,因此步骤函数现在可以清除哪个间隔。在 SKEL.EFFECTS.Slide.animate
然后在 SKEL.EFFECTS.Slide.stop
和 SKEL.EFFECTS.Slide.step (第 575 行)中
我认为应该这样做,但我无法在浏览器中真正测试它。如果我的代码不太工作,我一定错过了一些东西,但我仍然确信这就是问题所在,你只需要弄清楚如何解决它(或更改库=D)。你只需尝试我的建议,让我知道它是如何运作的。
干杯
编辑:我等不及了,所以我用 JSFiddle 来测试,是的,它适用于这些更改。 查看一下。
编辑2:更正了拼写错误:在代码的第一位仍然引用 skel_animate_id 而不是 skel_animate_ids。
Hey, I got the problem. The thing is this library isn't expecting you to use multiple animations at a time. the function SKEL.EFFECTS.Slide.animate which inits the animations creates a field in the animated object, called skel_animate_id, which is in fact the id of a timer set up to do the animation.
As this library doesn't expect multiple animations at a time, when you create a new animation, it just does
element.skel_animate_id = setInterval(.....
, and if you are following me, you'll realize that anything that was onskel_aimate_id
before (i.e. the library's only reference to any previous animation's timers) is lost after that assignment.Now, there's a step function, called by the timers, which is in charge of recognizing when the animation has ended, and stop the timer itself, but it does that by calling
clearInterval(element.skel_animate_id);
, which will obviously only clear the timer related to the last attribute animated.Long story short, when you call the second attribute's animation (before the first one ended), you leave an open timer, which keeps on going and going "animating" the first attribute (i.e. setting it to it's final value).
EDIT: Live demo of fix.
THE GUILTY SNIPPET
Lines [488-531]
POSSIBLE SOLUTION
I'd have
skel_animate_ids
as an array, and store every interval with a reference to the attribute animated, so the step function nows which interval to clear.in SKEL.EFFECTS.Slide.animate
then in SKEL.EFFECTS.Slide.stop
and in SKEL.EFFECTS.Slide.step (line 575)
I think that should do it, but I can't really test it in my browser. If my code doesn't quite work, I must have missed something, but I'm still sure that's the problem, you just have to figure out how to solve it (or change libraries =D). You just try my suggestion, let me know how it worked.
Cheers
EDIT: I couldn't wait, so I whipped a JSFiddle to test, and yeah, it works with those changes. Check it out.
EDIT2: Corrected typo: was still referencing skel_animate_id instead of skel_animate_ids in the first bit of code.
在你急于从滑块中删除功能的过程中,如果你能原谅我的语言,你基本上就毁掉了它:
语法荧光笔应该已经告诉你出了什么问题。你注释掉了应用程序设计中关键变量的定义。
至少尝试一下,让所有内容都连接到那里的
sliderNav
变量。这就是您试图模仿的功能。In your haste to remove functionality from the slider, you basically butchered it, if you can pardon my language:
The syntax highlighter should already tell you what's wrong.You commented out the definition for a critical variable in the application's design.
Try at the very least, letting everything connected to the
sliderNav
variable there. That is the functionality you are trying to mimic.
