我已经按照Bootstrap示例来实现thumbnails with captions。但是，我的标题文本具有不同的长度，导致三个缩略图的高度不同。这看起来很难看。为了解决这个问题，我尝试了matchHeight jQuery插件，但这没有效果。
这是我的代码：
<html>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js" type="text/javascript"></script>
<script src="js/jquery.matchHeight-min.js" type="text/javascript"></script>
<script type="text/javascript">
$(".thumbnail").matchHeight({ byRow: true, });
</script>
</head>
<body>
...
<div class="row">
<div class="col-lg-4 col-md-4 col-xs-12">
<div class="thumbnail">
<img class="img-responsive" src="img/img-1.jpg" alt="">
<div class="caption">
<h4>Heading 1</h4>
<p>...</p>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4 col-xs-12">
<div class="thumbnail">
<img class="img-responsive" src="img/img-2.jpg" alt="">
<div class="caption">
<h4>Heading 2</h4>
<p>...</p>
</div>
</div>
</div>
<div class="col-lg-4 col-md-4 col-xs-12">
<div class="thumbnail">
<img class="img-responsive" src="img/img-3.jpg" alt="">
<div class="caption">
<h4>Heading 3</h4>
<p>...</p>
</div>
</div>
</div>
</div>
...
</body>
我在这里缺少什么？如何让这三个缩略图很好地对齐？

尝试使用js：
(function() {
$(function() {
$('.thumbnail').matchHeight({
byRow: true,
property: 'height',
target: null,
remove: false
});
});
})();

我最终使用来自this answer的巧妙技巧，并编写了我自己的代码。 #mq-detector元素告诉我何时切换媒体查询而不必硬编码视口宽度。然后我迷上了窗口的resize回调，知道用户何时更改了浏览器窗口的大小：
<script type="text/javascript">
(function() {
$(window).resize(checkAdjustThumbnailHeight);
$(document).ready(checkAdjustThumbnailHeight);
})();
</script>
第一次呈现页面时会调用checkAdjustThumbnailHeight函数，并且每次浏览器的resize事件都会触发。该功能检查介质检测器元素并相应地调整缩略图高度：
function checkAdjustThumbnailHeight() {
if ($("#mq-detector > span.visible-lg").is(":visible")) {
adjustThumbnailHeight();
}
else if ($("#mq-detector > span.visible-md").is(":visible")) {
adjustThumbnailHeight();
}
else if ($("#mq-detector > span.visible-sm").is(":visible")) {
inheritThumbailHeight();
}
else if ($("#mq-detector > span.visible-xs").is(":visible")) {
inheritThumbailHeight();
}
else { }
}
请注意，对于sm和xs（实际像素值请参阅here）尺寸，我不会修改缩略图高度，因为在这些情况下缩略图会一个在另一个上方呈现，而不是彼此相邻。对于md和lg尺寸，我将缩略图高度设置为最大尺寸：
function adjustThumbnailHeight() {
var heights = [ ];
$(".thumbnail").each(function() {
heights.push( $(this).height() );
});
var max = Math.max.apply(null, heights);
$(".thumbnail").each(function() {
$(this).height(max);
});
}
function inheritThumbailHeight() {
$(".thumbnail").each(function() {
$(this).css("height", "inherit");
});
}
这似乎工作正常。
ADDENDUM 由于某些图片可能需要更长时间才能完成加载，因此缩略图的高度可能会偏斜。因此，我使用imageLoaded插件来推迟调整缩略图高度，直到所有图像都完成加载。
