找出容器中最后一行不完整文本的长度

问题描述

有没有办法用JavaScript来找出容器中（不完整的）最后一行文本的渲染宽度（例如在div中）？

Is there a way, with JavaScript, to find out the rendered width of the (incomplete) last line of text in a container (e.g. in a div)?

例如，假设我有以下HTML：

For example, suppose I have the following HTML:

    <div style="display: table-cell; text-align: justify">
      Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.
    </div>

如果div不够宽，浏览器会将文本分成多行，可能就像这样：

If the div is not wide enough, the browser will break the text into multiple lines, possibly like this:

Lorem ipsum dolor sit amet,  consectetur adipiscing
elit, sed do eiusmod tempor incididunt ut labore et
dolore magna aliqua.

如何找出最后一行的渲染宽度（以像素为单位）（dolore magna aliqua 。）来自JavaScript？

How can I find out the rendered width, in pixels, of the last line ("dolore magna aliqua.") from JavaScript?

$(".borded-textbox").each(function(index, elem) {
  $(elem).append('<span class="endline"></span>')
  var endline = $(elem).find(".endline");
//var sizeOfDiv = $(".borded-textbox").width();
  var sizeOfLeftSpace = parseInt(endline.offset().left);

  endline.css('width', parseInt(endline.offset().left));
   endline.addClass('processed');
  $(".length").append(sizeOfLeftSpace);
});
