织梦ckeditor增加一键排版功能

在博客园里面有人放出了一个ckeditor自动排版功能的代码,但并不是织梦的,直接使用在织梦上是不显示的,为此我借用大神的代码略加改造,让织梦的ckeditor也带有一键排版功能。

第一步

include -> ckeditor -> plugins 目录下新建autoformat文件夹,在autoformat里面新建一个plugin.js文件。
plugin.js文件内容:
//一键排版
(function () {
    CKEDITOR.plugins.add('autoformat', {
        requires: ['styles', 'button'],
        init: function (a) {
            a.addCommand('autoformat', CKEDITOR.plugins.autoformat.commands.autoformat);
            a.ui.addButton('AutoFormat', {
                label: "一键排版",
                command: 'autoformat',
                icon: this.path + "images/autoformat.png"
            });
        }
    });
    CKEDITOR.plugins.autoformat = {
        commands: {
            autoformat: {
                exec: function (editor) {
                    formatText(editor);
                }
            }
        }
    };

    //格式化
    function formatText(editor) {
        var myeditor = editor;
        if (myeditor.mode == "wysiwyg") {
            var tempimg = new Array();
            var temptable = new Array();
            var tempobject = new Array();

            var isPart = false; //暂时无法实现局部格式化
            if (!isPart) {
                var tmpDiv = document.createElement("DIV");
                var editorhtml = myeditor.getData();
                editorhtml = editorhtml.replace(/<div style="page-break-after: always;?">\s*<span style="display: none;?">&nbsp;<\/span>\s*<\/div>/gi, '<p>[page]</p>');  //将div span标签替换为p 标签
                tmpDiv.innerHTML = editorhtml.replace(/&nbsp;/gi, '').replace(/<div/gi, '<p').replace(/<\/div/gi, '</p');     //移除空格标签,div替换为p标签。
                if (window.navigator.userAgent.toLowerCase().indexOf("msie") > 0) {
                    tmpDiv.innerHTML = tmpDiv.innerHTML.replace(/<\/p>/gi, '<br /><\/p>');      //每个段落相隔一行
                }
                var tables = tmpDiv.getElementsByTagName("TABLE");
                if (tables != null && tables.length > 0) {
                    for (var j = 0; j < tables.length; j++) {
                        temptable[temptable.length] = tables[j].outerHTML;
                    }
                    var formattableCount = 0;
                    for (var j = 0; j < tables.length;) {
                        tables[j].outerHTML = "#FormatTableID_" + formattableCount + "#";
                        formattableCount++;
                    }
                }

                var objects = tmpDiv.getElementsByTagName("OBJECT");
                if (objects != null && objects.length > 0) {
                    for (var j = 0; j < objects.length; j++) {
                        tempobject[tempobject.length] = objects[j].outerHTML;
                    }
                    var formatobjectCount = 0;
                    for (var j = 0; j < objects.length;) {
                        objects[j].outerHTML = "#FormatObjectID_" + formatobjectCount + "#";
                        formatobjectCount++;
                    }
                }

                var imgs = tmpDiv.getElementsByTagName("IMG");
                if (imgs != null && imgs.length > 0) {
                    for (var j = 0; j < imgs.length; j++) {
                        var t = document.createElement("IMG");
                        t.alt = imgs[j].alt;
                        t.src = imgs[j].src;
                        t.width = imgs[j].width;
                        t.height = imgs[j].height;
                        t.align = imgs[j].align;
                        tempimg[tempimg.length] = t;
                    }
                    var formatImgCount = 0;
                    for (var j = 0; j < imgs.length;) {
                        imgs[j].outerHTML = "#FormatImgID_" + formatImgCount + "#";
                        formatImgCount++;
                    }
                }

                var strongarray = new Array();
                var strongcount = 0;
                for (var i = 0; i < tmpDiv.getElementsByTagName('b').length; i++) {

            }
        } else {
            alert('必须在设计模式下操作!');

    }

    function processFormatText(textContext) {

})();
autoformat里面新建一个文件夹images,里面放入插件的图标autoformat.png,我提供了两个autoformat.png供大家下载使用,在文章最底部。

第二步

打开include -> inc 目录下的 inc_fun_funAdmin.php
搜索extraPlugins找到
$config['extraPlugins'] = 'dedepage,multipic,addon';
修改为
$config['extraPlugins'] = 'dedepage,autoformat,multipic,addon';

第三步

打开include -> ckeditor 目录下 ckeditor.inc.php
搜索MultiPic,找到
array( 'TextColor', 'BGColor', 'MyPage','MultiPic','Code')
修改为
array( 'TextColor', 'BGColor', 'MyPage','AutoFormat','MultiPic')

至此,一键排版功能添加完成,做编辑的可以省下很多工作量了,最后附上两个图标供大家使用:

扁平化autoformat.png
普通autoformat.png
