blocks|key|2811665|text|也许最简单的方法是使用这个答案中描述的OnMouseOver和OnMouseOut事件：https://stackoverflow.com/a/10709196/121737|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|2811666|我更喜欢使用一个图像，相同的宽度作为一个正常的图标，但高度的两倍。此图像将显示两个图标，一个在另一个之上，上面一个是普通图标，下面是翻转图标：|2811667|img.icon+{

img.icon#facebook+{

}|code-block|syntax|javascript|2811668|在此之后，在HTML中声明图标就清晰多了：|2811669|<img+class="icon"+id="twitter"+/>
<img+class="icon"+id="facebook"+/>

Perhaps the easiest way to do this uses the <code>OnMouseOver</code> and <code>OnMouseOut</code> events described in this answer: <a href="https://stackoverflow.com/a/10709196/121737">https://stackoverflow.com/a/10709196/121737</a>

I would prefer to do this using one image, the same width as a normal icon but twice the height. This image would show two icons, one above the other, the upper one being the normal icon, the lower being the rolled over icon:

<pre><code>img.icon {
 display: block;
 width: 4ex; height: 4ex;
 background-size: 4ex 8ex;
 background-position: 0 0;
}

img.icon:hover {
 background-position: 0 -4ex;
}

img.icon#twitter {
 background-image:url('icons/twitter.jpg');
}

img.icon#facebook {
 background-image:url('icons/facebook.jpg');
}
</code></pre>

After this declaring the icons in HTML is much cleaner:

<pre><code>&lt;img class="icon" id="twitter" /&gt;
&lt;img class="icon" id="facebook" /&gt;
&lt;img class="icon" style="background-image:url('icons/other_icon.jpg')" /&gt;
</code></pre>

blocks|key|4924424|text|对于你的代码，你有：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4924425|<img+class="icon"+rel="popover"+trigger:+"hover"+data-placement="top"+data+content="This+is+a+popover"src="images/brandable.png"> Brandable</li>|code-block|syntax|javascript|4924426|trigger:+"hover"不是有效的html。Bootstrap帮助文档备注：“选项可以通过数据属性或JavaScript传递。对于数据属性，请将选项名称附加到数据-，如在data-animation=""中。”|offset|length|style|CODE|4924427|因此，相反，您可能希望包含data-trigger="hover“，而且看起来在src=之前缺少一个空格。|4924428|另外，在html和javascript中也有位置top。你只需要在一个地方声明。因此，您可以从img标记中删除data-placement="top“，或者在javascript中删除它，这样它就变成了$('.icon').popover({placement:'top'});|4924429|在你的函数前面也有"$“。根据代码所在的位置，您可能会遇到jquery冲突。为了确认，您需要发布在错误日志中看到的任何错误。如果您使用chrome，右键单击>+web+inspect+>单击底部的红色x，然后复制您在那里看到的任何错误。|4924430|entityMap^0|0|0|0|G|2H|H|0|14|4|0|2T|12|0|A|1|0^^$0|@$1|2|3|4|5|6|7|U|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|V|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|W|8|@$I|X|J|Y|K|L]|$I|Z|J|10|K|L]]|9|@]|A|$]]|$1|M|3|N|5|6|7|11|8|@$I|12|J|13|K|L]]|9|@]|A|$]]|$1|O|3|P|5|6|7|14|8|@$I|15|J|16|K|L]]|9|@]|A|$]]|$1|Q|3|R|5|6|7|17|8|@$I|18|J|19|K|L]]|9|@]|A|$]]|$1|S|3|-4|5|6|7|1A|8|@]|9|@]|A|$]]]|T|$]]

For your code you have:

<pre><code>&lt;img class="icon" rel="popover" trigger: "hover" data-placement="top" data content="This is a popover"src="images/brandable.png"&gt;&lt;br&gt;Brandable&lt;/br&gt;&lt;/li&gt;
</code></pre>

<code>trigger: "hover"</code> isn't valid html. Bootstrap help document notes, "Options can be passed via data attributes or JavaScript. For data attributes, append the option name to data-, as in <code>data-animation=""</code>."

So instead you would want to include data-trigger="hover" also looks like your missing a space before <code>src=</code>.

Also you have placement top in the html and also in the javascript. You only need to declare in one place. So you can delete data-placement="top" from the img tag, or in your javascript you can remove it so it would just be <code>$('.icon').popover({placement:'top'});</code>

Also you have "<code>$</code>" in front of your function. Depending on where that code is located you may have a jquery conflict. To note for sure you'll need to post whichever error you are seeing in your error log. If you use chrome right click > web inspect > click the red x at the bottom and copy any errors you see in there.

this is over a year late, but i found this to work:
<a href="http://jsfiddle.net/dalecameron/QZj5P/11/" rel="nofollow">Fiddler Link</a> 
using this JS:

<pre><code>$(function(){
 $('[data-toggle=popover]').popover({
 trigger: 'focus',
 html: true,
 title: 'Toolbox'
}) 
});
</code></pre>

And this html:

<pre><code> &lt;img src="https://encrypted-tbn1.gstatic.com/images?q=tbn:ANd9GcS-eTmHxgicEfq4K-sEz_X52cq56uBP2l8cr_q8ivOavSIca5TYtQ"
 data-toggle="popover" tabindex="50" data-content="test &lt;b&gt;text&lt;/b&gt;" data-placement="right"/&gt;
</code></pre>

You need to allow the image to accept focus with the tabindex property. That was the key for me. Remove the "trigger: 'focus' line if you want the popover to stay open on click events...
 
Hope it helps!

blocks|key|4924519|text|将属性放在jquery变量中，而不是标签中|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4924520|<img+class="icon"+rel="popover"+src="images/brandable.png"/>|code-block|syntax|javascript|4924521|按如下方式添加脚本|4924522|<script>

Put attributes in jquery variable instead of tag

<pre><code>&lt;img class="icon" rel="popover" src="images/brandable.png"/&gt;
</code></pre>

Add script as following

<pre><code>&lt;script&gt;
$('document').ready(function() {
 var popOverSettings = {
 placement: 'top',
 selector: '.icon',
 title:'Brandable',
 trigger: "hover",
 content:'This is a popover'
 };
$(this).popover(popOverSettings);
});
&lt;/script&gt;
</code></pre>

So I have a list of icons, I'm trying to get a popover to activate when you hover over an icon, I can't seem to get it to work, any help would be appreciated.

<pre><code>&lt;img class="icon" rel="popover" trigger: "hover" data-placement="top" data content="This is a popover"src="images/brandable.png"&gt;&lt;br&gt;Brandable&lt;/br&gt;&lt;/li&gt;
</code></pre>

And i have this in a separate js file

<pre><code>$('.icon').popover({placement:'top'});
</code></pre>
