Building a WYSIWYG HTML Editor Part 1/2 - execCommand examples
(Page 3 of 7 )

Now that we're a little bit more familiar with the execCommand method, let's look at a list of some of the commands that we can perform with it (the complete list is available here):
  • ForeColor: Get or set the foreground color of the selected region.
  • BackColor: Get or set the background color of the selected region.
  • Bold: Toggles between the select region being bolded.
  • Italic: Toggles between the selected region being italicised.
  • Underline: Toggles between the select region being underlined.
  • Copy: Copies the selected region to the clipboard.
  • Cut: Removes the selected region from the document.
  • Paste: Adds data from clipboard to region (if applicable).
  • InsertHorizontalRule: Adds a horizontal rule to the region.
  • InsertImage: Displays an IE defined modal dialog that contains full image selection features, alt tag modification, border setting, etc.
  • InsertMarquee: Converts the selected text into a marque.
  • InsertSelectDropDown: Adds a drop down list to the region.
  • Print: Displays the windows print dialog so that the region can be printed.
  • Refresh: Refreshes the region.
  • CreateLink: Displays an IE defined modal dialog that lets you add a hyperlink using either selected text or new text.
  • InsertUnorderedList: Toggles between the selected text being an unordered list and normal text.
As you can see, we can do some pretty powerful things with the execCommand method. Let's build an advanced HTML content editor that allows us to toggle between HTML mode and WYSIWYG mode, format text, add images, links, lists and more.
