Copy As HTML From VSCode
JS生成可自定义语法高亮HTML^code

这里有更好的方案，具体看我的这篇博客博客代码高亮的另一种思路

这篇文章介绍了如何在博客里插入一段 pretty 代码框的方法（以博客园为例），主要是因为实在是受不了博客园以及其他一些博客自带代码框的样子了w~

这篇文章很长很长，你可以直接点击这里，直接跳到源代码处，复制代码，或者滑到文章最底部查看使用方法。

原理是利用 VSCode 的 Copy With Syntax Highlighting 这个自带的功能，其实很多 IDE 都具有此类功能：

Ctrl + 逗号，打开设置，搜索找到上图中的选项就可以开启高亮语法复制为 HTML 代码的这个功能了，当然现在直接粘贴并不能直接获取到剪切板内 TEXT 文本，也无法获取带高亮样式的内 HTML 文本。

其实是可以获取剪切板的 HTML 文本的，js 提供了一个 onpaste 事件，可以在函数事件的 event 参数中获取到剪切板的内容了。

event.clipboardData.getData( Format: String )

如果要获取剪切板的纯文本，String 为 “text/plan”，如果是 HTML 文本，String 为 “text/html”：

CODE01.js

12345

document.onpaste = function (e){

    var cb_data = e.clipboardData.getData("text\/html");

    // var cb_data = e.clipboardData.getData("text\/plain");

    console.log(cb_data);

}

然后，在 IDE 里面复制一段高亮显示着的代码，浏览器里面 Ctrl + V，控制台会 log 出来一堆东西：

为方便查看把这串从 VSCode剪切板里面得到的内容 Prettify 一下，其实很有规律：

CODE02.html

12345678910111213141516171819



<div style="color: #d4d4d4;background-color: #1e1e1e;font-family: Meslo LG L DZ, Microsoft YaHei;font-weight: 200;font-size: 16px;line-height: 34px;white-space: pre;">

    <div>

        <span style="color: #9cdcfe;">document</span>

        <span style="color: #d4d4d4;">.</span>

        <span style="color: #dcdcaa;">onpaste</span>

        <span style="color: #d4d4d4;"> = </span>

        <span style="color: #569cd6;">function</span>

        <span style="color: #d4d4d4;"> (</span>

        <span style="color: #9cdcfe;">e</span>

        <span style="color: #d4d4d4;">){</span>

    </div>

    <div>

        <span style="color: #d4d4d4;">    </span>

        <span style="color: #569cd6;">var</span>

        ........

    </div>

</div>



可能你也发现了规律了吧，其实这就是大多数 IDE 的语法高亮显示功能的原理，整个编辑器就相当于浏览器的窗口，窗口中每段文字都被特定样式的标签包裹起来……每行一个 div 又包裹很多 span 的行内元素，就这样一行一行堆砌，然后就实现了这个功能。

得到的这些 HTML 文本基本上就可以复制到各大博客的编辑器来用了，但是我们除了去设置整个编辑器的样式这个方法之外，没有其他更简便的办法去改变高亮的样式了，而且如果剪切板中 HTML 标签内为制表符或者是一些空白字符的话，编辑器通常会将其忽略，就没有代码缩进显示，比如我在博客园的编辑器中直接复制 CODE02 的代码到 HTML 编辑文本域里面，代码的缩进全部都没有了，于是就想到对这些剪切板里面的内容处理一下，可以灵活输出自己想要展示 Code 的 HTML。

于是花了一天的时间，从最初的 HTML模板布局到整个功能的实现，以及 JS 代码修改，最后完善了整个程序。直接给大家看 demo，其实前面的代码框就是演示……，上面的两个代码展示框就是 JS 生成的（普通的字符串的处理），加入了行数标识以及标题标识功能，之后还添加了一个 light 主题，两者样式兼容移动端：

theme.js

12345678910111213141516

var themes = {

    "dark": {

        c_title_bg: "#252525",

        c_title_fg: "#ededed",

        c_editor_bg: "#1e1e1e",

        c_sideNum_bg: "#1e1e1e",

        c_sideNum_fg: "#727272"

    },

    "light": {

        c_title_bg: "#dcdcdc",

        c_title_fg: "#999",

        c_editor_bg: "#f5f5f5",

        c_sideNum_bg: "#e5e5e5",

        c_sideNum_fg: "#999"

    }

};

这里就不卖关子了，直接贴代码吧，里面有注释。

使用方法
1. 在 copyAsHTML.html 中引入 copyAsHTML.js
2. 打开 VSCode，并在设置中确保已勾选控制在复制时是否同时复制语法高亮选项
3. Ctrl + C 复制一段编辑器的代码
4. Chrome 打开 copyAsHTML.html，页面空白区 Ctrl + V 粘贴
5. F12 打开控制台，Copy 输出的所有内容
6. 粘贴 HTML 代码到 HTML 编辑器中，即可
Advance
