window.print() 仅打印屏幕的“可见”部分答案

【问题标题】：window.print() only prints the "viewable" part of the screenwindow.print() 仅打印屏幕的“可见”部分
【发布时间】：2021-06-15 21:11:38
【问题描述】：

我有一个可滚动的屏幕，上面有一个打印按钮，并且在其 onclick 事件上调用了“window.print()”函数。

我的问题是它只打印屏幕的“可见”部分，而不是整个屏幕。如果页面是可滚动的，如果内容不适合 1 页，则打印应扩展到 2（或更多）页。但就我而言，它总是只打印一页，其余内容不打印。

【问题讨论】：

默认只打印可见页面，如果要在所有页面中显示内容，则在新选项卡中显示要打印的所有内容，然后在该新选项卡中提供 window.print。如果您的意思是只打印可见内容，那么您需要将html 和body 标签设置为height:100%，
谢谢Naren，我已经将html 和body 标签设置为height:100%
我已经设置，当点击按钮时，它会直接指向另一个 html 文件，其中我有打印按钮，并且在其 onclick 事件上调用“window.print()”函数。
设置溢出：可见；为我工作。

标签： javascript css html

【解决方案1】：

可能重复：window.print() is not printing the whole page

您基本上必须将以下内容添加到您的主 css 文件中

@media print {
      body, html, #wrapper {
          height: 100%;
      }
}

【讨论】：

我有文件 print.css 包含@media print { body, html, #wrapper { width: 100%; } }
它应该可以工作。我试过height: 100% 和width: 100%。两者似乎都解决了这个问题。
谢谢，当我也将div标签设置为height: 100% 时它工作了

【解决方案2】：

仅添加 100% 的高度和宽度对我不起作用。所以深入研究这个我发现了一个解决方案，添加 display:inline-block 在某些情况下也可以工作。

@media print {
  body, html, #page-container, .scrollable-page, .ps, .panel {
      height: 100% !important;
      width: 100% !important;
      display: inline-block;
  }

}

【讨论】：

请详细说明您显示的代码解决了哪些情况。如果您在找到它的地方也添加源代码，那就太好了。
如果我添加 display: inline-block;然后下一页确实出现在打印预览中，只是这个页面是空的（所以没有显示它应该有的内容......

【解决方案3】：

将高度设置为 100% 并溢出以在 css 中可见

@media print {
  .print-container {
    height: 100%;
    overflow: visible;
  }
}

<div class="print-container">

"But I must explain to you how all this mistaken idea of denouncing pleasure and praising pain was born and I will give you a complete account of the system, and expound the actual teachings of the great explorer of the truth, the master-builder of human happiness. No one rejects, dislikes, or avoids pleasure itself, because it is pleasure, but because those who do not know how to pursue pleasure rationally encounter consequences that are extremely painful. Nor again is there anyone who loves or pursues or desires to obtain pain of itself, because it is pain, but because occasionally circumstances occur in which toil and pain can procure him some great pleasure. To take a trivial example, which of us ever undertakes laborious physical exercise, except to obtain some advantage from it? But who has any right to find fault with a man who chooses to enjoy a pleasure that has no annoying consequences, or one who avoids a pain that produces no resultant pleasure?"

Section 1.10.33 of "de Finibus Bonorum et Malorum", written by Cicero in 45 BC
"At vero eos et accusamus et iusto odio dignissimos ducimus qui blanditiis praesentium voluptatum deleniti atque corrupti quos dolores et quas molestias excepturi sint occaecati cupiditate non provident, similique sunt in culpa qui officia deserunt mollitia animi, id est laborum et dolorum fuga. Et harum quidem rerum facilis est et expedita distinctio. Nam libero tempore, cum soluta nobis est eligendi optio cumque nihil impedit quo minus id quod maxime placeat facere possimus, omnis voluptas assumenda est, omnis dolor repellendus. Temporibus autem quibusdam et aut officiis debitis aut rerum necessitatibus saepe eveniet ut et voluptates repudiandae sint et molestiae non recusandae. Itaque earum rerum hic tenetur a sapiente delectus, ut aut reiciendis voluptatibus maiores alias consequatur aut perferendis doloribus asperiores repellat."

1914 translation by H. Rackham
"On the other hand, we denounce with righteous indignation and dislike men who are so beguiled and demoralized by the charms of pleasure of the moment, so blinded by desire, that they cannot foresee the pain and trouble that are bound to ensue; and equal blame belongs to those who fail in their duty through weakness of will, which is the same as saying through shrinking from toil and pain. These cases are perfectly simple and easy to distinguish. In a free hour, when our power of choice is untrammelled and when nothing prevents our being able to do what we like best, every pleasure is to be welcomed and every pain avoided. But in certain circumstances and owing to the claims of duty or the obligations of business it will frequently occur that pleasures have to be repudiated and annoyances accepted. The wise man therefore always holds in these matters to this principle of selection: he rejects pleasures to secure other greater pleasures, or else he endures pains to avoid worse pains."
