javascript - 在ckeditor中显示html标签

我将默认打开以下内容的ckeditor。

<textarea id="editor1" name="editor1" rows="30" cols="120"><p>We can use&nbsp;<strong>prettify&nbsp;</strong>to auto-format the Computer programming code at web page.</p>

<p><strong>How to use?</strong></p>

<p>Just add below line;</p>

<p><code class="prettyprint"><span style="line-height: 1.6em;">&lt;script src=&quot;https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js&quot;&gt;&lt;/script&gt;</span></code</p>

<p><span style="line-height: 1.6em;">Then, put the code line in below tab;</span></p>

<p><code class="prettyprint">&lt;code class=&quot;prettyprint&quot;&gt;...&lt;/code&gt;</code></p>

<p><span style="color: rgb(0, 0, 0); font-family: monospace; font-size: medium; line-height: normal;">or,</span></p>

<p>Download the complete code files&nbsp;from&nbsp;<a href="https://code.google.com/p/google-code-prettify/">https://code.google.com/p/google-code-prettify/</a>(even can learn more about prettify)&nbsp;&nbsp;to your server and change above script tag line like below;</p>

<p><code class="prettyprint">&lt;script src=&quot;path/to/directory/run_prettify.js&quot;&gt;&lt;/script&gt;</code><br />&nbsp;</p>
</textarea>
<script>CKEDITOR.replace( "editor1");</script>

但是，输出中缺少HTML标记代码。输出低于（下划线）；



我们可以使用prettify在网页上自动设置计算机编程代码的格式。

如何使用？

只需添加以下行；

然后，将代码行放在选项卡下面；

...

要么，

从https://code.google.com/p/google-code-prettify/(even下载完整的代码文件可以了解有关Prettify的更多信息到您的服务器，并更改脚本标记行，如下所示；



预期输出：

请帮助，我想念的地方。

最佳答案

这看起来像是此问题中的另一个类似问题：How to prevent CKEditor from stripping < and > (greater-than/less-than)

解决方法是使用setData设置值。以下是我在4.1示例中进行的测试。

<textarea id="editor1">
    <p>foo</p>
</textarea>
<script>
    var txt = '<p>We can use&nbsp;<strong>prettify&nbsp;</strong>to auto-format the Computer programming code at web page.</p><p><strong>How to use?</strong></p><p>Just add below line;</p><p><code class="prettyprint"><span style="line-height: 1.6em;">&lt;script src=&quot;https://google-code-prettify.googlecode.com/svn/loader/run_prettify.js&quot;&gt;&lt;/script&gt;</span></code</p><p><span style="line-height: 1.6em;">Then, put the code line in below tab;</span></p><p><code class="prettyprint">&lt;code class=&quot;prettyprint&quot;&gt;...&lt;/code&gt;</code></p><p><span style="color: rgb(0, 0, 0); font-family: monospace; font-size: medium; line-height: normal;">or,</span></p><p>Download the complete code files&nbsp;from&nbsp;<a href="https://code.google.com/p/google-code-prettify/">https://code.google.com/p/google-code-prettify/</a>(even can learn more about prettify)&nbsp;&nbsp;to your server and change above script tag line like below;</p><p><code class="prettyprint">&lt;script src=&quot;path/to/directory/run_prettify.js&quot;&gt;&lt;/script&gt;</code><br />&nbsp;</p>'
    CKEDITOR.on('instanceReady', function(ev) {
        ev.editor.setData(txt);
    });
    CKEDITOR.replace( 'editor1', { allowedContent: 'p' } );
</script>
