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({
