<page size="A4"> Contrary to popular belief,Lorem Ipsum is not simply random text. It has roots in a piece of classical Latin literature from 45 BC,making it over 2000 years old. Richard McClintock,a Latin professor at Hampden-Sydney College in Virginia,looked up one of the more obscure Latin words,consectetur,from a Lorem Ipsum passage,and going through the cites of the word in classical literature,discovered the undoubtable source. Lorem Ipsum comes from sections 1.10.32 and 1.10.33 of "de Finibus Bonorum et Malorum" (The Extremes of Good and Evil) by Cicero,written in 45 BC. This book is a treatise on the theory of ethics,very popular during the Renaissance. The first line of Lorem Ipsum,"Lorem ipsum dolor sit amet..",comes from a line in section 1.10.32. The standard chunk of Lorem Ipsum used since the 1500s is reproduced below for those interested. Sections 1.10.32 and 1.10.33 from "de Finibus Bonorum et Malorum" by Cicero are also reproduced in their exact original form,accompanied by English versions from the 1914 translation by H. Rackham.

从上面的代码中,我检查了新的< page class ='a4'>< / page>已创建但我无法获得超出内容并将其放入新创建的页面中.
解决方法
如果您使用
Summer Note或类似类型的html编辑器,我们可以消除在html中包含文本节点的想法,因为这些编辑器通常将所有内容包装在< p>中.标签.例如,如果您编写以下内容
This is First Line This is Second Line This is Third Line
编辑器将生成这样的HTML.
<p>This is First Line</p> <p>This is Second Line</p> <p>This is Third Line</p>
生成的HTML也可以有表格,列表和可能是图像,
<h2>A Title</h2> <p>A 2-3 line paragraph</p> <hr><!-- just to prettify --> <table>...</table> <ul><li>An Un-ordered List</li></ul> <ol><li>An Un-ordered List</li></ol> <p><img src="#" alt="An Image"></p>
没有任何权衡,我们无法将它们分成页面.因此,如果我们可以通过一些权衡取舍,我们可以完成这项工作.关于这些HTML编辑器的一个好处是它们倾向于生成大部分Block level Elements作为页面的直接子项.因此,通过计算每个Block元素子元素的位置和高度,我们可以检查子元素是否适合使用简单算法的页面,或者如果不是,则将其移动到下一页面.
