ckeditor内联保存/提交

Question

我无法弄清楚如何从CKEditor实例中获取已编辑的数据并将其发布到URL.

我在看这个:

http://nightly.ckeditor.com/3995/samples/inlineall.html

我无法弄清楚如何保存更改.我可以将要编辑的新编辑的数据与要编辑的元素的ID一起发布到PHP吗？

与此类似:

editor.on('configLoaded', function(){
    // do some stuff
});

我希望我能做到这样的事情:

editor.on('clickAway', function(e){
    id = e.id();
    // do some ajax stuff
});

但我似乎无处可寻.

有没有人知道如何做到这一点？

谢谢.

我确信有很多方法可以解决这个问题,但这是我的解决方案.我正在使用Smarty模板引擎,但这种技术也适用于vanilla HTML.

首先,这是一个存储在名为"dog_fleas.tpl"的模板文件中的HTML的示例:

<script type="text/javascript" src="/js/ckeditor/ckeditor.js"></script>
<script type="text/javascript" src="/js/admin/mycms.js"></script>
<div>
  <div id="flea-blurb" tpl="/templates/dog_fleas.tpl" contenteditable="true">
    <h1>My Dog Has Fleas</h1>
    <p>This text is editable via the CMS!</p>
  </div>
  <p>This text is not editable</p>
</div>

处理内联编辑的javascript(mycms.js)是:

$(document).ready(function() {

    CKEDITOR.disableAutoInline = true;

    $("div[contenteditable='true']" ).each(function( index ) {

        var content_id = $(this).attr('id');
        var tpl = $(this).attr('tpl');

        CKEDITOR.inline( content_id, {
            on: {
                blur: function( event ) {
                    var data = event.editor.getData();

                    var request = jQuery.ajax({
                        url: "/admin/cms-pages/inline-update",
                        type: "POST",
                        data: {
                            content : data,
                            content_id : content_id,
                            tpl : tpl
                        },
                        dataType: "html"
                    });

                }
            }
        } );

    });

});

上面的代码做了一些事情:

1. 它将具有属性contenteditable ="true"的任何div标记转换为内联可编辑.
2. 编辑内容后(模糊),可编辑元素id,tpl文件名和编辑内容通过ajax调用发送到服务器.

在我的情况下,tpl属性对于识别正在编辑的文件是必要的.元素id指定修改了哪个元素.

虽然我的示例仅包含一个可编辑区域,但此代码支持单个文件中的多个可编辑区域.

在服务器端,这是我的PHP代码.我正在使用一个框架,所以我的$ this - > _ POST()函数可能看起来有点不寻常,但希望你能得到这个想法:

    // Get the posted parameters
    $new_content = $this->_POST('content');
    $content_id  = $this->_POST('content_id');
    $tpl_filename = $this->_POST('tpl');

    // Get the contents of the .tpl file to edit
    $file_contents = file_get_contents(APPPATH . 'views' . $tpl_filename);

    // create revision as a backup in case of emergency
    $revised_filename = str_replace('/', '.', $tpl_filename);
    $revised_filename = ltrim ($revised_filename, '.');
    file_put_contents(APPPATH . 'views/templates/revisions/' . $revised_filename . '.' . time(), $file_contents);

    // Prepare to match the DIV tag
    // Credit to: http://stackoverflow.com/questions/5355452/using-a-regular-expression-to-match-a-div-block-having-a-specific-id
    $re = '% # Match a DIV element having id="content".
        <div\b             # Start of outer DIV start tag.
        [^>]*?             # Lazily match up to id attrib.
        \bid\s*+=\s*+      # id attribute name and =
        ([\'"]?+)          # $1: Optional quote delimiter.
        \b' . $content_id . '\b        # specific ID to be matched.
        (?(1)\1)           # If open quote, match same closing quote
        [^>]*+>            # remaining outer DIV start tag.
        (                  # $2: DIV contents. (may be called recursively!)
          (?:              # Non-capture group for DIV contents alternatives.
          # DIV contents option 1: All non-DIV, non-comment stuff...
            [^<]++         # One or more non-tag, non-comment characters.
          # DIV contents option 2: Start of a non-DIV tag...
          | <            # Match a "<", but only if it
            (?!          # is not the beginning of either
              /?div\b    # a DIV start or end tag,
            | !--        # or an HTML comment.
            )            # Ok, that < was not a DIV or comment.
          # DIV contents Option 3: an HTML comment.
          | <!--.*?-->     # A non-SGML compliant HTML comment.
          # DIV contents Option 4: a nested DIV element!
          | <div\b[^>]*+>  # Inner DIV element start tag.
            (?2)           # Recurse group 2 as a nested subroutine.
            </div\s*>      # Inner DIV element end tag.
          )*+              # Zero or more of these contents alternatives.
        )                  # End 2$: DIV contents.
        </div\s*>          # Outer DIV end tag.
        %isx';

    if (preg_match($re, $file_contents, $matches))
    {
        $content_to_replace = $matches[0];

        $replacement_content = $content_to_replace;

        // Replace the inner content of $replacement_content with $new_content
        $replacement_content = preg_replace('/(<div(?:.*?)>)(?:.*)(<\/div>)/msi',"$1" . $new_content . "$2", $replacement_content);

        // Now replace the content_to_replace with $replacement content in the HTML
        $new_file_contents = str_replace($content_to_replace, $replacement_content, $file_contents);

        // write out the new .tpl file
        file_put_contents(APPPATH . 'views' . $tpl_filename, $new_file_contents);
    }

上面的PHP代码基本上是加载HTML,使用正确的id定位div标签,然后用通过ajax调用发送的内容替换该div标签的内容.然后将HTML重新保存到服务器.我还包括一些代码来存储备份修订,以防万一出现严重错误.

我意识到正则表达式并不总是最好的解决方案.就我而言,很难使用PHP Dom对象模型,因为我的HTML内容不是有效的HTML.如果您的系统比我的系统简单,您可能会考虑使用Dom对象模型.

我希望这有帮助!
