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?

几乎和高梅的评论一样,只是用了行高而不是高度。
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。
这将给出给定文本中的总行数
text.split("
").length
