在Summernote编辑器中将所选文本替换为插入

Question

我正在尝试为summernote v0.8.9创建一个插件。

在我的最小可行示例下面查找：

$(document).ready(function() {
  $('.summernote').summernote({
    height: 300,
    tabsize: 2,
    toolbar: [
      ['insert', ['synonym', 'codeview']]
    ],
  });
});

(function(factory) {
  /* global define */
  if (typeof define === 'function' && define.amd) {
    // AMD. Register as an anonymous module.
    define(['jquery'], factory);
  } else if (typeof module === 'object' && module.exports) {
    // Node/CommonJS
    module.exports = factory(require('jquery'));
  } else {
    // Browser globals
    factory(window.jQuery);
  }
}(function($) {

  // minimal dialog plugin
  $.extend($.summernote.plugins, {
    'synonym': function(context) {
      var self = this;

      var ui = $.summernote.ui;

      var $editor = context.layoutInfo.editor;
      var options = context.options;

      // add context menu button
      context.memo('button.synonym', function() {
        return ui.button({
          contents: '<i class="fa fa-snowflake-o">',
          tooltip: 'Create Synonym',
          click: context.createInvokeHandler('synonym.showDialog')
        }).render();
      });

      self.initialize = function() {
        var $container = options.dialogsInBody ? $(document.body) : $editor;

        var body = '<div class="form-group">' +
          '<label>Element</label>' +
          '<input id="input-element" class="form-control" type="text"/>' +
          '</div>' +
          '<label>Synonym</label>' +
          '<input id="input-synonym" class="form-control" type="text" placeholder="Insert your synonym" />'
        var footer = '<button href="#" class="btn btn-primary ext-synonym-btn">OK</button>';

        self.$dialog = ui.dialog({
          title: 'minimal dialog title',
          fade: options.dialogsFade,
          body: body,
          footer: footer
        }).render().appendTo($container);
      };

      self.destroy = function() {
        self.$dialog.remove();
        self.$dialog = null;
      };

      self.showDialog = function() {
        self
          .openDialog()
          .then(function(data) {
            // [workaround] hide dialog before restore range for IE range focus
            ui.hideDialog(self.$dialog);
            context.invoke('editor.restoreRange');
            self.insertToEditor(data);
            // do something with dialogData
            console.log("dialog returned: ", data)
            // ...
          })
          .fail(function() {
            context.invoke('editor.restoreRange');
          });

      };

      self.openDialog = function() {
        return $.Deferred(function(deferred) {
          var $dialogBtn = self.$dialog.find('.ext-synonym-btn');
          var $elemInput = self.$dialog.find('#input-element')[0];
          var $synonymInput = self.$dialog.find('#input-synonym')[0];

          var selectedText = $.selection()
          $('#input-element').val(selectedText);
          console.log("show dialog: " + selectedText)

          ui.onDialogShown(self.$dialog, function() {
            context.triggerEvent('dialog.shown');

            $dialogBtn
              .click(function(event) {
                event.preventDefault();

                deferred.resolve({
                  element: $elemInput.value,
                  synonym: $synonymInput.value
                });
              });
          });

          ui.onDialogHidden(self.$dialog, function() {
            $dialogBtn.off('click');

            if (deferred.state() === 'pending') {
              deferred.reject();
            }
          });

          ui.showDialog(self.$dialog);
        });
      };

      //text that is written to the editor
      this.insertToEditor = function(data) {
        console.log("synonym: " + data.synonym)

        var $elem = $('<synonym>', {
          words: data.synonym
        });;

        $elem.text(data.element)

        context.invoke('editor.insertNode', $elem[0]);
      };
    }
  });
}));

<div class="container">
  <div class="summernote">
    <p>Hello World!</p>
    This text should be replaced by the dialog. </div>
</div>

正如您在上面看到的，我正在使用api function context.invoke('editor.insertNode', $elem[0]);，它基本上是从页面开头的对话框窗口中插入元素的。

但是，我想用对话框中创建的元素替换所选单词。

任何建议如何做到这一点？

感谢您的答复！

Answer 1

您处在正确的轨道上。看来您必须通过以下方式保存选择：

context.invoke('editor.saveRange');   // note line 94 in the snippet

然后使用：

context.invoke('editor.insertText', data.element); // note line 133 in the snippet

我要插入data.element，但显然您可以在其中放置synonym或其他任何内容：）

Their documentation并不是很好，但是经过反复试验，还是可以的。

$(document).ready(function() {
  $('.summernote').summernote({
    height: 300,
    tabsize: 2,
    toolbar: [
      ['insert', ['synonym', 'codeview']]
    ],
  });
});

(function(factory) {
  /* global define */
  if (typeof define === 'function' && define.amd) {
    // AMD. Register as an anonymous module.
    define(['jquery'], factory);
  } else if (typeof module === 'object' && module.exports) {
    // Node/CommonJS
    module.exports = factory(require('jquery'));
  } else {
    // Browser globals
    factory(window.jQuery);
  }
}(function($) {

  // minimal dialog plugin
  $.extend($.summernote.plugins, {
    'synonym': function(context) {
      var self = this;

      var ui = $.summernote.ui;

      var $editor = context.layoutInfo.editor;
      var options = context.options;

      // add context menu button
      context.memo('button.synonym', function() {
        return ui.button({
          contents: '<i class="fa fa-snowflake-o">',
          tooltip: 'Create Synonym',
          click: context.createInvokeHandler('synonym.showDialog')
        }).render();
      });

      self.initialize = function() {
        var $container = options.dialogsInBody ? $(document.body) : $editor;

        var body = '<div class="form-group">' +
          '<label>Element</label>' +
          '<input id="input-element" class="form-control" type="text"/>' +
          '</div>' +
          '<label>Synonym</label>' +
          '<input id="input-synonym" class="form-control" type="text" placeholder="Insert your synonym" />'
        var footer = '<button href="#" class="btn btn-primary ext-synonym-btn">OK</button>';

        self.$dialog = ui.dialog({
          title: 'minimal dialog title',
          fade: options.dialogsFade,

      self.destroy = function() {
        self.$dialog.remove();
        self.$dialog = null;

      self.showDialog = function() {
        self

          .then(function(data) {
            // [workaround] hide dialog before restore range for IE range focus
            ui.hideDialog(self.$dialog);
            context.invoke('editor.restoreRange');

          var $elemInput = self.$dialog.find('#input-element')[0];
          var $synonymInput = self.$dialog.find('#input-synonym')[0];

          var selectedText = $.selection()
          $('#input-element').val(selectedText);
          context.invoke('editor.saveRange');
          console.log("show dialog: " + selectedText)

          ui.onDialogShown(self.$dialog, function() {
            context.triggerEvent('dialog.shown');

            $dialogBtn
              .click(function(event) {
                event.preventDefault();

                deferred.resolve({
                  element: $elemInput.value,
                  synonym: $synonymInput.value
                });
              });
          });

          ui.onDialogHidden(self.$dialog, function() {
            $dialogBtn.off('click');

            if (deferred.state() === 'pending') {

            }
          });

          ui.showDialog(self.$dialog);
        });
      };

      //text that is written to the editor
      this.insertToEditor = function(data) {
        console.log("synonym: " + data.synonym)

        var $elem = $('<synonym>', {
          words: data.synonym
        });;

        $elem.text(data.element)           

        context.invoke('editor.insertText', data.element);
      };
    }
  });
}));
