本文实例讲述了CKeditor富文本编辑器使用技巧之添加自定义插件的方法。分享给大家供大家参考，具体如下：

首先就是在CKeditor的plugins目录下新建一个目录qchoice：

qchoice目录下的结构如下：

然后， images中如下：

dialogs中如下：

我们先来看plugins.js文件的内容：

(function() {
  CKEDITOR.plugins.add("qchoice", {
    requires: ["dialog"],
    init: function(a) {
      a.addCommand("qchoice", new CKEDITOR.dialogCommand("qchoice"));
      a.ui.addButton("qchoice", {
        label: "qchoice",//调用dialog时显示的名称
        command: "qchoice",
        icon: this.path + "images/qchoice.jpg"//在toolbar中的图标
      });
      CKEDITOR.dialog.add("qchoice", this.path + "dialogs/qchoice.js")
    }
  })
})();

再来看qchoice.js文件的内容：

CKEDITOR.dialog.add('qchoice', function (editor) { //要和plugin.js 中的command 一致
  var escape = function (value) {
    return value;
  };
  return {
    title: '', //对话框标题
    minWidth: 500, //对话框宽度
    minHeight: 600,//对话框高度
    contents: [{  //对话框内容
      id: 'choice',
      name: 'choice',
      label: '插入选择题答案',
      title: '插入选择题答案',

      else {
        return false;
      }
    }
  };
});
function htmlEncode(str) {
  var temp = document.createElement("div");
  (temp.textContent != null) ? (temp.textContent = str) : (temp.innerText = str);
  var output = temp.innerHTML;
  temp = null;
  return output;
}

之后就是config.js配置文件的内容了：

    { name: 'extent', items: ["qchoice"] }
  ];
  config.toolbar_Full = [

    '/',
    ['Styles','Format','Font','FontSize'],
    ['TextColor','BGColor'],
    ["qchoice"]
  ];
  config.image_previewText=' ';
  config.filebrowserImageUploadUrl = 'uploadFiles';
  // config.extraPlugins = 'justify';
  config.extraPlugins += (config.extraPlugins ? ',justify' : 'justify');
  config.extraPlugins += (config.extraPlugins ? ',qchoice' : 'qchoice');
  // config.extraPlugins="linkbutton";

  config.format_tags = 'p;h1;h2;h3;pre';
  // Simplify the dialog windows.
  config.removeDialogTabs = 'image:advanced;link:advanced';
  config.image_previewText=' ';
  config.entities = false;
};

好啦，到这里，自定义插件就算是放入成功了。咱们自定义的插件主要的逻辑结构就是在qchoice.js文件中，可以改变它的内容，来实现不同的功能。

好啦，本次记录就到这里了。
