[JS] Execcommand command details

The document.exe ccommand () method uses the following syntax to process HTML data:
Copy content to clipboard
Code:
Document.exe ccommand (scommand [, interaction mode, dynamic parameters])

Scommand is the command parameter ("2d-position" in the following example). If the interaction mode parameter is true, the dialog box is displayed. If the interaction mode parameter is false, the dialog box is not displayed ("false" in the following example indicates that the dialog box is not displayed). A dynamic parameter is generally an available value or a property value ("true" in the following example ").

Document.exe ccommand ("2d-position", "false", "true ");

Execcommand () can be called to implement many functions of the browser menu, such as saving files, opening new files, undo and redo operations... And so on. With this method, you can easily implement the text editor in the webpage.

If it is used flexibly, it can help us complete various projects.

An example is as follows:

1. Implementation of the [select all] command
[Format]: document.exe ccommand ("selectall ")
[Description] All content on the webpage will be selected!
[Example] Add:
Select All

2. Implementation of the open command
[Format]: document.exe ccommand ("open ")
[Note] This is similar to the webbrowser control commands in programming design such as VB. You can also consider it here.
[Example] Add:
Open

3. Implementation of the "Save as" command
[Format]: document.exe ccommand ("saveas ")
[Note] Save the webpage to another directory on the local disk!
[Example] Add:
Save

4. Implementation of the *** print *** command
[Format]: document.exe ccommand ("print ")
[Note] Of course, you must have installed a printer!
[Example] Add:
Print
