您可以考虑一下我从头开始创建的以下插件(这不是一个完整的解决方案,但它显示了正确的方向):
(function() {
'use strict';
CKEDITOR.plugins.add( 'prettify', {
icons: 'prettify',
init: function( editor ) {
editor.on( 'mode', function( event ) {
if( editor.mode == 'wysiwyg' )
insertResources( editor );
});
editor.addCommand( 'prettify', {
exec: function( editor ) {
var selection = editor.getSelection(),
startElement = selection.getStartElement();
if ( startElement.hasClass( 'prettyprint' ) )
return;
var contents = startElement.getText();
// Naive pre-processing.
contents = contents.replace( /\n/g ,'<br>' );
contents = contents.replace( /\t/g ,' ' );
contents = contents.replace( / /g ,' ' );
startElement.setHtml( prettyPrintOne( contents, 'js', 0 ) );
startElement.addClass( 'prettyprint' );
}
});
editor.ui.addButton( 'Prettify', {
label: 'Prettify',
command: 'prettify',
toolbar: 'insert'
});
}
});
function insertResources( editor ) {
var outerHead = CKEDITOR.document.getHead(),
innerHead = editor.document.getHead(),
path = CKEDITOR.plugins.getPath( 'prettify' );
outerHead.append( CKEDITOR.document.createElement( 'script', {
attributes: {
type: 'text/javascript',
async: 'true',
src: path + 'lib/prettify.js'
}
}));
innerHead.append( CKEDITOR.document.createElement( 'link', {
attributes: {
rel: 'stylesheet',
href: path + 'lib/prettify.css'
}
}));
}
})();
要运行它,请将Google Prettify库解压缩到插件lib
目录中。prettify
然后尝试以下 HTML 并使用工具栏中的按钮进行美化pre
:
<textarea cols="80" id="editor1" name="editor1" rows="10">
<pre>function insertResources( editor ) {
var outerHead = CKEDITOR.document.getHead(),
innerHead = editor.document.getHead(),
path = CKEDITOR.plugins.getPath( 'prettify' );
</pre>
<p>Foo:</p>
<pre>outerHead.append( CKEDITOR.document.createElement( 'script', {
attributes: {
type: 'text/javascript',
async: 'true',
src: path + 'lib/prettify.js'
}
}));</pre>
<p>Bar:</p>
<pre>innerHead.append( CKEDITOR.document.createElement( 'link', {
attributes: {
rel: 'stylesheet',
href: path + 'lib/prettify.css'
}
}));
}</pre>
</textarea>
<script>
CKEDITOR.replace( 'editor1', {
extraPlugins: 'prettify',
toolbar: [
[ 'Source', '-', 'NewPage', 'Preview', '-', 'Templates' ],
[ 'Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord', '-', 'Undo', 'Redo' ],
[ 'Bold', 'Italic' ],
'/',
[ 'Prettify']
]
} );
</script>
