ckeditor添加自定義按鈕整合swfupload實現批量上傳圖片
給ckeditor添加自定義按鈕，由於ckeditor只能上傳一張圖片，如果要上傳多張圖片就要結合ckfinder，而ckfinder是收費的，所以就想通過自定義按鈕整合swfupload實現一次上傳多張圖片的功能
首先下載並安裝ckeditor。
下載swfupload解壓拷貝到對應的文件目錄下
3、自定義工具欄按鈕:
我們可以自定義ckeditor工具欄要顯示的按鈕，工具欄按鈕定義可以參考這裏。
現在我們需要向工具欄添加一個自定義功能的按鈕。ckeditor工具欄中的每個按鈕都是作為插件定義在ckeditor\plugins\ 目錄中。我們在ckeditor\plugins\中創建一個新文件夾imagedef。在imagedef文件夾內，我們創建一個plugin.js文件，它的代碼如下：
CKEDITOR.plugins.add(
"imagedef", {
requires: ["dialog"], //當按鈕觸發時彈出對話框
init: function (a) {
a.addCommand("imagedef", new CKEDITOR.dialogCommand("imagedef"));
a.ui.addButton(
"Imagedef", {
label: "圖片",
command: "imagedef",
icon: this.path + "imagedef.gif"
});
CKEDITOR.dialog.add("imagedef", this.path + "dialogs/imagedef.js");
}
}
);
在上面的代碼中我們指定自定義按鈕的圖標imagedef.gif，imagedef.gif放在imagedef文件夾中。
在imagedef文件夾下新建一個dialogs目錄，在dialogs目錄下新建一個imagedef.js文件，就是上面代碼調用的imagedef.js文件
CKEDITOR.dialog.add(
"imagedef",
function (b)
{
return {
title: "圖片",
minWidth: 590,
minHeight: 300,
contents: [{
id: "tab1",
label: "",
title: "",
expand: true,
padding: 0,
elements: [{
type: "html",
html: initImageDlgInnerHtml() //對話框中要顯示的內容，這裏的代碼將發在下面
}]
}],
onOk: function () { //對話框點擊確定的時候調用該函數
var D = this;
var imes = getCkUploadImages(); //獲取上傳的圖片，用於取路徑，將圖片顯示在富文本編輯框中
$(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 () { //對話框初始化時調用
initEventImageUpload(); //用於註冊上傳swfupload組件
},
onShow: function () {
clearCkImageUpload(); //在對話框顯示時作一些特殊處理
}
};
}
);

接下來我們需要註冊imagedef插件。原文中的給出方法是在ckeditor.js中註冊，這會使以後升級新版本遇到困難。提倡使用下面的方法在config.js中註冊自定義插件：
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‘; //去掉文本框下面出現body p 等
config.extraPlugins = "imagedef"; //註冊自定義按鈕
};


最後，在ckeditor中顯示自定義按鈕linkbutton，代碼如下：
下面代碼是在頁面上寫的，當然可以根據自己的需求來定，寫在什麽位置


//編輯框初始化上傳圖片的回調----------自定義按鈕插件
//上面有個cke_dialog_start_button_z樣式是根據自己的需要來寫的
function initEventImageUpload() { //對上傳控件的註冊
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() { //對對話框彈出時作特殊處理
if ($("#ck_fs_upload_progress").html().indexOf(".jpg") != -1) {
$("#ck_fs_upload_progress").html("");
}
$("#ck_pic_div").html("");
}

function getCkUploadImages() {
return $("#ck_pic_div").find("img");
}
var ckSwfu; //初始化上傳控件
function ckeditorInitSwfu(progress, btn, spanButtonPlaceHolder) {
var uploadUrl = "${BasePath}/commodity_com/img/uploadCommodityImg.ihtml?type=1";
//在firefox、chrome下，上傳不能保留登錄信息，所以必須加上jsessionid。
var jsessionid = $.cookie("JSESSIONID");
if (jsessionid) {
uploadUrl += "?jsessionid=" + jsessionid;
}
ckSwfu = new SWFUpload({
