将内容添加到最后一页的底部

标签: css css3 wkhtmltopdf

我使用wkhtmltopdf从HTML创建PDF报告,我需要创建一个遵循这种模式的自定义报告:

  1. 第一页顶部的一些信息。
  2. 一个可以有1到n行的表(它应该使用它需要的任意数量的页面)
  3. 最后一页末尾的一些信息。
  4. 把所有这些放在一起就可以了。但是因为第3步信息会立即显示在表格之后,是否有办法将内容放在页面的末尾?

    我甚至不确定此解决方案是基于CSS还是基于wkhtmltopdf。

查看“页脚和标题”部分。

您可以使用--footer-html结合一些JavaScript来执行此操作。

wkhtmltopdf --footer-html footer.html http://www.stackoverflow.com/ so.pdf

我根据上面链接中提供的示例基于footer.html的内容:

<!DOCTYPE html>

<script>
window.onload = function() {
    var vars = {};
    var x = document.location.search.substring(1).split('&');
    for (var i in x) {
        var z = x[i].split('=', 2);
        vars[z[0]] = unescape(z[1]);
    }

    //if current page number == last page number
    if (vars['page'] == vars['topage']) {
        document.querySelectorAll('.extra')[0].textContent = 'extra text here';
    }
};
</script>

<style>
.extra {
    color: red;
}
</style>

<div class="extra"></div>

这是一项非常困难的任务,我认为你现在不能用纯CSS来解决这个问题(虽然我很想被证明是错误的)。

对确定的分页符(page-break-inside: avoid;)的支持也不是最好的。事实上,到目前为止我认为它不适用于表格。您可能最终会在页面制动器周围分割出一些行。 (Webkit呈现一个PDF,然后将其剪切成单个页面,大多数情况下无论如何......)

我解决这个难题的方法是在单个页面的大小中创建单个占位符div,然后在生成PDF之前在这些占位符之间使用一些编程语言分发内容。

在最后一个这样的包装器中,您可以在底部添加一个绝对定位的页脚。

以下是一些示例代码:

<!DOCTYPE HTML>
<html lang="en-US">
<head>
    <meta charset="UTF-8">
    <title>Sample Data</title>
    <style>

        * {
            padding: 0;
            margin: 0;
        }   

        .page {
            page-break-inside: avoid;
            height: 1360px;

            position: relative;
        }

        table {
            border-collapse: collapse;
            width: 100%;
        }

        td {
            border: 1px solid #ccc;
            padding: .23em;
        }

        .footer {
            position: absolute;
            color: red;
            bottom: 0;
        }

    </style>
</head>
<body>

<div class="page one">

我跟你的意思有点麻烦。 “紧接在桌子后面”和“在桌子末尾”的内容之间有什么区别?

tfoot元素可能是您正在寻找的内容:

<table>
    <thead>
        <tr><th>Header</th></tr>
    </thead>
    <tfoot>
        <tr><th>Footer</th></tr>
    </tfoot>
    <tbody>
        <tr><td>Data</td></tr>
        <tr><td>Data</td></tr>
        <tr><td>Data</td></tr>
    </tbody>
</table>

如果没有,你能详细说明吗?您拥有的HTML的简短示例或者它的外观以及您希望它看起来的图片可能会有所帮助。
