ckeditor添加自定义按钮整合swfupload实现批量上传图片
给ckeditor添加自定义按钮，由于ckeditor只能上传一张图片，如果要上传多张图片就要结合ckfinder，而ckfinder是收费的，所以就想通过自定义按钮整合swfupload实现一次上传多张图片的功能
首先下载并安装ckeditor。
下载swfupload解压拷贝到对应的文件目录下
3、自定义工具栏按钮:
我们可以自定义ckeditor工具栏要显示的按钮，工具栏按钮定义可以参考这里。
现在我们需要向工具栏添加一个自定义功能的按钮。ckeditor工具栏中的每个按钮都是作为插件定义在ckeditor\plugins\ 目录中。我们在ckeditor\plugins\中创建一个新文件夹imagedef。在imagedef文件夹内，我们创建一个plugin.js文件，它的代码如下：
CKEDITOR.plugins.add(
    "imagedef", {
        requires: ["dialog"], //当按钮触发时弹出对话框
        init: function (a) {
            a.addCommand("imagedef", new CKEDITOR.dialogCommand("imagedef"));
            a.ui.addButton(
                "Imagedef", {
                    label: "图片",
                    command: "imagedef",
                    icon: this.path + "imagedef.gif"
                });
            CKEDITOR.dialog.add("imagedef", this.path + "dialogs/imagedef.js");
        }
    }
);
在上面的代码中我们指定自定义按钮的图标imagedef.gif，imagedef.gif放在imagedef文件夹中。
在imagedef文件夹下新建一个dialogs目录，在dialogs目录下新建一个imagedef.js文件，就是上面代码调用的imagedef.js文件
CKEDITOR.dialog.add(
    "imagedef",
    function (b)
    {
        return {
            title: "图片",
            minWidth: 590,
            minHeight: 300,
            contents: [{
                id: "tab1",
                label: "",
                title: "",
                expand: true,
                padding: 0,
                elements: [{
                    type: "html",
                    html: initImageDlgInnerHtml() //对话框中要显示的内容，这里的代码将发在下面
                }]
            }],
            onOk: function () { //对话框点击确定的时候调用该函数
                    var D = this;
                    var imes = getCkUploadImages(); //获取上传的图片，用于取路径，将图片显示在富文本编辑框中
                    $(imes).each(function () {
                        D.imageElement = b.document.createElement(‘img‘);
                        D.imageElement.setAttribute(‘alt‘, ‘‘);
                        D.imageElement.setAttribute(‘_cke_saved_src‘, $(this).attr("src"));
                        D.imageElement.setAttribute(‘src‘, $(this).attr("src"));
                        D.commitContent(1, D.imageElement);
                        if (!D.imageElement.getAttribute(‘style‘)) {
                            D.imageElement.removeAttribute(‘style‘);
                        }
                        b.insertElement(D.imageElement);
                    });
                },
                onLoad: function () { //对话框初始化时调用
                    initEventImageUpload(); //用于注册上传swfupload组件
                },
                onShow: function () {
                    clearCkImageUpload(); //在对话框显示时作一些特殊处理
                }
        };
    }
);
 
接下来我们需要注册imagedef插件。原文中的给出方法是在ckeditor.js中注册，这会使以后升级新版本遇到困难。提倡使用下面的方法在config.js中注册自定义插件：
CKEDITOR.editorConfig = function (config) {
    config.toolbar_Full = [
        [‘Source‘, ‘Preview‘, ‘-‘, ‘Templates‘],

        [‘Cut‘, ‘Copy‘, ‘Paste‘, ‘PasteText‘, ‘PasteFromWord‘, ‘-‘, ‘Print‘, ‘SpellChecker‘, ‘Scayt‘],
        [‘Undo‘, ‘Redo‘, ‘-‘, ‘Find‘, ‘Replace‘, ‘-‘, ‘SelectAll‘, ‘RemoveFormat‘],
        [‘Form‘, ‘Checkbox‘, ‘Radio‘, ‘TextField‘, ‘Textarea‘, ‘Select‘, ‘Button‘, ‘ImageButton‘, ‘HiddenField‘],
        ‘/‘,
        [‘Bold‘, ‘Italic‘, ‘Underline‘, ‘Strike‘, ‘-‘, ‘Subscript‘, ‘Superscript‘],
        [‘NumberedList‘, ‘BulletedList‘, ‘-‘, ‘Outdent‘, ‘Indent‘, ‘Blockquote‘],
        [‘JustifyLeft‘, ‘JustifyCenter‘, ‘JustifyRight‘, ‘JustifyBlock‘],
        [‘Link‘, ‘Unlink‘, ‘Anchor‘],
        [‘Imagedef‘, ‘Table‘, ‘HorizontalRule‘, ‘Smiley‘, ‘SpecialChar‘, ‘PageBreak‘],
        ‘/‘,
        [‘Styles‘, ‘Format‘, ‘Font‘, ‘FontSize‘],
        [‘TextColor‘, ‘BGColor‘]
    ];
    config.resize_maxWidth = 775;
    config.removePlugins = ‘elementspath‘; //去掉文本框下面出现body p 等
    config.extraPlugins = "imagedef"; //注册自定义按钮
};
 

最后，在ckeditor中显示自定义按钮linkbutton，代码如下：
下面代码是在页面上写的，当然可以根据自己的需求来定，写在什么位置
 

//编辑框初始化上传图片的回调----------自定义按钮插件
//上面有个cke_dialog_start_button_z样式是根据自己的需要来写的
function initEventImageUpload() { //对上传控件的注册
    ckeditorInitSwfu("ck_fs_upload_progress", "stop_id", "ck_btn_id");
    $("#ck_fs_upload_progress").parent().find("object").css({
        "height": "24px",
        "width": "82px"
    });
    $("#ck_btn_start").mouseover(function () {
        $(this).css({
            "cursor": "hand",
            "background-position": "0 -1179px"
        });
    });
}

function clearCkImageUpload() { //对对话框弹出时作特殊处理
    if ($("#ck_fs_upload_progress").html().indexOf(".jpg") != -1) {
        $("#ck_fs_upload_progress").html("");
    }
    $("#ck_pic_div").html("");
}

function getCkUploadImages() {
    return $("#ck_pic_div").find("img");
}
var ckSwfu; //初始化上传控件
function ckeditorInitSwfu(progress, btn, spanButtonPlaceHolder) {
    var uploadUrl = "${BasePath}/commodity_com/img/uploadCommodityImg.ihtml?type=1";
    //在firefox、chrome下，上传不能保留登录信息，所以必须加上jsessionid。
    var jsessionid = $.cookie("JSESSIONID");
    if (jsessionid) {
        uploadUrl += "?jsessionid=" + jsessionid;
    }
    ckSwfu = new SWFUpload({
        upload_url: uploadUrl,
        flash_url: "${BasePath}/res/base/plugin/swfupload/swfupload.swf",

//开始上传图片
function ckUploadImageStart(obj) {

//回调重写
