This time I will bring you the user experience of jQuery optimizing text that exceeds the specified number of words. What are the precautions for jQuery optimizing the user experience of text that exceeds the specified number of words. The following is a practical case, let’s take a look.
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>jQuery自动添加省略号</title>
<script src="http://apps.bdimg.com/libs/jquery/2.1.4/jquery.min.js"></script>
<script type="text/javascript">
$(function () {
$(".figcaption").each(function (i) {
var pH = $(this).height();
var $p = $("p", $(this)).eq(0);
while ($p.outerHeight() > pH) {
$p.text($p.text().replace(/(\s)*([a-zA-Z0-9]+|\W)(\.\.\.)?$/, "..."));
};
});
});
</script>
<style>
*{
padding: 0px;
margin: 0px;
}
.figcaption{
width: 300px;
height: 50px;
/*根据父元素的高度来添加省略号
*可以任意设置显示的行数
*/
border: 1px solid red;
}
</style>
</head>
<body>
<p class="figcaption">
<p>
You probably can't do it (currently?) without a fixed-width font like Courier. With
a fixed-width font every letter occupies the same horizontal space, so you could
probably count the letters and multiply the result with the current font size in
ems or exs. Then you would just have to test how many letters fit on one line, and
then break it up.</p>
