尝试用jquery子串概念,但没有运气,
我试过
>查找div高度
>找到行高
> div height / line height =行数
这是代码：
var divheight = $("#startegy-sections-targeting-exclude").height();
var lineheight = $("#startegy-sections-targeting-exclude").css('line-height');
console.log(Math.round(divheight/parseInt(lineheight)));
但没有成功,你们可以帮助我吗
解决方法
您可以使用ThreeDots插件进行jQuery：
http://tpgblog.com/2009/12/21/threedots-the-jquery-ellipsis-plugin/
在您的< div>上调用ThreeDots()时,将max_rows设置为4.只需查看该页面上的示例,您还可以设置自定义的“阅读更多”链接.但请注意,您必须将文本包装成额外的< span>,如下所示：
<div class="text_here">
<span class="ellipsis_text">
your text
</span>
</div>
…然后jQuery代码行将是：
$('.text_here').ThreeDots({ max_rows:4 });
