CKEditor 自主控制图片上传
在ASP.NET中使用CKEditor编辑器，如果想控制图片上传，即把上传的图片路径名存到数据中，可以自定义一个上传功能
首先自定义CKEditor的配置文件
在config.js中添加以下代码，红色部分为增加添加图片插件语句
CKEDITOR.editorConfig = function (config) {
// Define changes to default configuration here. For example:
config.language = 'zh-cn';
// config.skin = 'v2';
config.uiColor = '#AADC6E';
config.toolbar =
[
['Source', '-', 'Preview', '-'],
['Cut', 'Copy', 'Paste', 'PasteText', 'PasteFromWord'],
['Undo', 'Redo', '-', 'Find', 'Replace', '-', 'SelectAll', 'RemoveFormat'],
'/',
['Bold', 'Italic', 'Underline'],
['NumberedList', 'BulletedList', '-', 'Outdent', 'Indent'],
['JustifyLeft', 'JustifyCenter', 'JustifyRight', 'JustifyBlock'],
['Link', 'Unlink', 'Anchor'],
['addpic', 'Flash', 'Table', 'HorizontalRule', 'Smiley', 'SpecialChar', 'PageBreak'], //此处的addpic为我们自定义的图标，非CKeditor提供。
'/',
['Styles', 'Format', 'Font', 'FontSize'],
['TextColor', 'BGColor'],
];
config.extraPlugins = 'addpic';
};
然后需要为添加图片按钮配置图片
在./ckeditor/plugins/目录下新建一个文件夹addpic,然后在其目录下添加两个文件，一个是名叫addpic.jpg的图片，就是添加图片按钮
的图标，另一个是plugin.js,就是配置此按钮的js代码
plugin.js文件内容
(function () {
//Section 1 : 按下自定义按钮时执行的代码
var a = {
exec: function (editor) {
show();
}
},
b = 'addpic';
CKEDITOR.plugins.add(b, {
init: function (editor) {
editor.addCommand(b, a);
editor.ui.addButton('addpic', {
label: '添加图片',
icon: this.path + 'addpic.JPG',
command: b
});
}
});
})();
现在编辑器中已经部署好了添加图片的功能图标，接下来我们就需要完成在点击它时，弹出一个上传文件的对话框，
其中弹出对话框我们使用用jquery开发的popup弹出对话框模式，所以在使用前需要加载相应的js文件
<script type="text/javascript" src="./Scripts/scripts/jquery.1.3.2.js"></script>
<script type="text/javascript" src="./Scripts/scripts/popup_layer.js"></script>
<!--因为我们要把图片加入到编辑其中所以需要通过 CKeditor 的jsAPI来操作，因此也许要加载下面的文件-->
<script type="text/javascript" src="./ckeditor/ckeditor.js"></script>
<!--下面的JS文件是需要我们自己写的，就是为了完成图片插入编辑器中-->
<script type="text/javascript" src="./ckeditor/addImage.js"></script>
addimage.js文件内容，也可是将其写在应用编辑器的页面test.aspx中,写成JS文件形式，如果在另个页面也需要此功能只需加载
此文件就行了，不必再复制js代码
function show() {
$("#ele6")[0].click();
}
function upimg(str) {//上传文件页面上传成功后将返回图片的完整路径名，然后我们就可以将其插入编辑其中
if (str == "undefined" || str == "") {
return;
}
str = "<img src='" + str + "'></img>";
CKEDITOR.instances.CKEditor_memo.insertHtml(str);//调用CKEditor的JS接口将图片插入
close();
}
function close() {
$("#close6")[0].click();
}
$(document).ready(function () {
new PopupLayer({ trigger: "#ele6", popupBlk: "#blk6", closeBtn: "#close6", useOverlay: true, offsets: { x: 50, y: 0} });
});
其中应用编辑器的页面test.aspx代码如下
具体如何部署CKEdtior官网上有许多详细介绍
这是官网上专门针对使用asp.net的部署，很详细了
