更新所有div元素的内部内容

Question

我的Div身高300px，宽度300px。

我想在Div中添加一些文字，所以我想查看文字数量 这个div区域会生成另一个Div标记并将其中的rest文本放入其中。 这可能吗？

或者这个： 如何将此文本转换为某些Div 300 * 300：

A fractal is a mathematical set that has a fractal dimension that usually exceeds its topological dimension[1] and may fall between the integers.[2] Fractals are typically self-similar patterns, where self-similar means they are "the same from near as from far"[3] Fractals may be exactly the same at every scale, or as illustrated in Figure 1, they may be nearly the same at different scales.[2][4][5][6] The definition of fractal goes beyond self-similarity per se to exclude trivial self-similarity and include the idea of a detailed pattern repeating itself.[2]:166; 18[4][7]

As mathematical equations, fractals are usually nowhere differentiable, which means that they cannot be measured in traditional ways.[2][6][8] An infinite fractal curve can be perceived of as winding through space differently from an ordinary line, still being a 1-dimensional line yet having a fractal dimension indicating it also resembles a surface.[1]:48[2]:15

The mathematical roots of the idea of fractals have been traced through a formal path of published works, starting in the 17th century with notions of recursion, then moving through increasingly rigorous mathematical treatment of the concept to the study of continuous but not differentiable functions in the 19th century, and on to the coining of the word fractal in the 20th century with a subsequent burgeoning of interest in fractals and computer-based modelling in the 21st century.[9][10] The term "fractal" was first used by mathematician Benoît Mandelbrot in 1975. Mandelbrot based it on the Latin frāctus meaning "broken" or "fractured", and used it to extend the concept of theoretical fractional dimensions to geometric patterns in nature.[2]:405[7]

结果必须是这样的事情：

Answer 1

尝试以下内容：

var str = "This is a very long string. You don't know exactly how much width you will need for it to be displayed";
var ar = str.split(" ");
var index = 0;
var $test = $("#test");

while($test.height() < 300){
    console.log($test.height());
 $test.html($test.html() +" "+ ar[index++]); 
    if(!ar[index]){break;}  
}

var fits = ar.splice(0,index-1);
$("#fixed").html(fits.join(" "));
$("#overflow").html(ar.join(" "));

这应该是一个很好的起点。
