寻找如何测量行数的想法
原标题:Looking for an idea how to measure line count

I want to take a text on a webpage and measure it s height in lines, regardless of any other parameter, so if I shrink the text width and get more lines, i will get the new line count.

有什么想法可以使用JS和jQuery做到这一点吗?

此外,什么样的行号技术是常见的?

最佳回答

几乎和高梅的评论一样,只是用了行高而不是高度。

问题回答

下面是一个小的jQuery函数:

$.fn.numLines = function() {
    var tmp = $( <div style="visibility:hidden;">x</div> ).appendTo(document.body);
    var lines = this.height() / tmp.height();
    tmp.remove();
    return lines;
};

您只需调用$(#someElement).numLines()即可检索行数。

这是一个演示:http://jsfiddle.net/ThiefMaster/sHzMP/

这将给出给定文本中的总行数

  text.split("
").length
