问题描述
在下面，有两段代码。对于无限滚动&搜索系统。一切正常，但搜索系统的问题是，如果我搜索某些东西，那么它会弄乱卡或框的位置。他们应该在一条线上，如果你搜索它们，但是那些稍微等等。我也添加了一张关于它的图片。第二个问题是，我的网站上有一个无限卷轴，但我想我必须将搜索系统更改为从JSON数据中搜索，这样才能正常工作？我的意思是，你在搜索中键入内容，单击enter然后它从JSON搜索匹配，然后在容器中显示它们。我希望我对我的问题足够清楚，我希望有人可以帮助我解决它:)。谢谢大家！ ：）
Down below, there's two pieces of codes. For infinite scroll & search system. Everything works, but the problem with the search system is that, if I search something, then it messes up positioning of the cards or boxes. They should be on one line, if you search them, but those a bit up etc.. I also have added an picture about that. 2nd problem is that, I have an Infinite scroll on my site, but I think I would have to change the search system to search from JSON Data, so it would work correctly? By that I mean, You type something into search, click enter then it searches matches from the JSON and then shows them in that container. I hope I was clear enough about my problem and I hope someone can help me out to solve it :). Thanks to everyone! :)

推荐答案
概述
首先，我无法看到
因为我不知道你的CSS是什么所以我只是对此做了一些猜测。我怀疑这可能是由于你的物品以某种方式实际渲染。为了协助这一点，我从注入的标记中删除了所有CSS，因为注入那些样式属性并不是最佳实践，并且坦率地难以调试，因为您似乎经历过。我做了一个尝试，但你需要调整我提供的CSS，因为它根本没有你的CSS。
since I do not know what your CSS consists of so I simply made some guesses on that. I suspect it may be due to the actual rendering of your items somehow. To assist in this I removed all the CSS from the injected markup as injecting those "style" attributes is not best practice and frankly difficult to debug as you seem to have experienced. I made an attempt but you will need to adjust the CSS I have provided as it simply does not have all yours in it.
为了帮助这个，我只是做了一个替换当前页面而不是每次附加，然后面对滚动/开始结束的挑战并处理搜索中断。
To assist with this, I simply did a "replace" with the current page rather than append each time and then face the challenge of end of scroll/start and deal with the search disruption of that.
我删除了在按钮上注入重复的id而不是使用类注入。这将解决无效HTML的问题，这会导致在某些时候出现意外结果，这将很难调试。
I removed the injection of duplicate id on the button and instead used a class injection instead. This will resolve the issue of the invalid HTML which would cause unexpected results at some point that would be very difficult to debug.
更难的问题是你的动态性质搜索页面上的对象列表时的items数组。我通过创建一个名为 currentSearch 的视图候选列表解决了这个问题，我已经自由地添加了一个名为 myApp.data的名称 as myApp.data.currentSearch 。
The more difficult issue is the dynamic nature of your items array when searching the on-page object list. This I have addressed by creation of a "view candidate list called currentSearch which I have taken the liberty of adding to a name called myApp.data as myApp.data.currentSearch.
说到命名空间，我这样做是为了避免我也使用自定义函数作为最佳实践。
Speaking of the namespace, I did that to avoid multiple global objects. I also did that with my custom functions as a best practice.
这是我使用的示例标记：
Here is my sample markup that I used:
<div id="search">
<input id="SearchItemsFromList" type="text" />
</div>
<ul id="inventory">
</ul>
CSS
这里的CSS很大程度上是从样式属性中提取的。我冒昧地命名它们不如第一风格的东西类，第二风格的东西等等，它们只是简单地与注入的序列进行协调这有减少注射管柱的额外好处大小也是。
Here is the CSS which in great part was extracted from the style properties. I took the liberty of naming them poorly as first-style-thing class, second-style-thing etc. which simply coordinate to the injected sequence of elements. This has the additional benefit of reducing the injection string size as well.
.li-style-thing {
padding: 8px;
font-weight: bold;
font-size: 13.5px;
}
.first-style-thing {
margin: 0%;
min-height: 295px;
width: 245.438px;
border-radius: 0px;
height: 295px;
box-shadow: inset 0px 0px 25px 2px #232323;
border: 1px solid black;
}
.second-style-thing {
text-decoration: underline;
text-align: left;
font-size: 14.5px;
color: #E8E8E8;
font-family: Roboto;
position: relative;
right: -3px;
}
.third-style-thing {
text-align: left;
color: #E8E8E8;
font-family: Roboto;
position: relative;
left: 3px;
}
.fourth-style-thing {
position: relative;
padding: 0%;
top: -33px;
}
.fifth-style-thing {
position: relative;
top: -129px;
background: rgba(0, 0, 0, 0.15);
display: block;
height: 163px;
}
.sixth-style-thing {
font-size: 22.5px;
font-family: Arial Black;
color: #E8E8E8;
}
.seventh-style-thing {
font-weight: normal;
font-size: 12px;
font-family: Roboto;
font: bold;
}
.eighth-style-thing {
position: relative;
left: -5px;
top: 50px;
}
.ninth-style-thing {
position: relative;
right: -5px;
top: 50px;
}
.btn {
position: relative;
display: block;
height: 1.5em;
width: 5em;
color: cyan;
background-color: blue;
font-weight: bold;
text-align: center;
padding-top: 0.5em;
margin: 1em;
text-decoration: none;
text-transform: uppercase;
}
#inventory {
display: block;
position: relative;
top: 1em;
left: 0em;
border: solid lime 1px;
}
#inventory li {
background-color: #888888;
}
#inventory li {
display: inline-block;
float: left;
}
.purchaseButton {
right: -8em;
top: 0;
}
#search {
height: 4em;
width: 100%;
background-color: #00aaaa;
padding: 1em;
}
代码：
关于代码，请注意 items 对象，我只需对您的注入代码进行逆向工程，并可能需要根据您的确切对象属性进行调整。
About the code, note the items object which I simply made from reverse engineering your injection code and likely needs adjusted to your exact object properties.
请注意 debounce 函数，它解决了您可能经常触发滚动/鼠标滚轮事件的问题。我添加了一个油门，您可以使用它，从这里借来：说到，我将wheel事件添加到scroll事件中，这样如果你在滚动的顶部/底部，当没有实际滚动时，鼠标滚轮也可以触发滚动。当卷轴位于顶部/底部时，我没有解决其他可能的挑战，例如向下/向上箭头;我会根据您的需要将此留给您解决。
Note the debounce function which addresses an issue where you might fire the scroll/mouse wheel events too often. I added a "throttle" which you might use instead, borrowed from here: https://remysharp.com/2010/07/21/throttling-function-calls Speaking of, I added the "wheel" event to the "scroll" event so that if you are at the top/bottom of the scroll the mouse wheel can also fire the scroll when no scroll actually occurs. I did not address other possible challenges such as the down/up arrow when the scroll is at the top/bottom; I will leave that up to you to address based upon your needs.
请注意，在输入搜索事件时，我会重置 currentSearch list。
Note that upon a "search" event when typing, I reset the currentSearch list.
我留下了一些 console.log ，你可以删除 - 但是允许你看到页面和一些事件火灾记录。
I left some console.log in place which you can remove - but allows you to see the page and some event fire logging.

关于代码的最后注意事项，你有一个很长的，很难维护的条件，我替换为添加带有排除项的数组，然后代码将它与过滤器一起使用： .filter（function（itemValue）{
return !!（myApp.data.excludes.indexOf（itemValue）== - 1）
}）
Final note on the code, you have a quite long, difficult to maintain conditional which I replaced by added an array with the exclusions and then the code uses it with a filter: .filter(function(itemValue) { return !!(myApp.data.excludes.indexOf(itemValue) == -1) })
