This document describes the rich text editing controls for web pages
|
|
available in recent mozilla browsers.<br>
|
|
<br>
|
|
<h1> Enabling Rich Text Editing in your web page:</h1>
|
|
<div style="margin-left: 40px;">Given a document, you can add the
|
|
attribute
|
|
"designMode" and set it to "on" to get an editable document. For
|
|
example,
|
|
in JavaScript, if you have an iframe with an id of 'edit', you can get
|
|
its
|
|
contentDocument and set designMode to "on" like this:<br>
|
|
<div style="margin-left: 40px;"><code>document.getElementById("edit").contentDocument.designMode="on";</code>
|
|
</div>
|
|
<br>
|
|
Right now, you can't completely turn off editing by setting designMode
|
|
to
|
|
"off." Setting designMode to "off" will prevent certain
|
|
operations
|
|
from being handled but typing and other actions are still possible.<br>
|
|
</div>
|
|
<br>
|
|
<h1>Invoking Commands:</h1>
|
|
<h2>execCommand<br>
|
|
</h2>
|
|
<div style="margin-left: 40px;">Given a document that has rich text
|
|
editing
|
|
enabled (see above),
|
|
you can invoke specific commands on the document by calling execCommand
|
|
with
|
|
3 parameters. For example, in JavaScript, if you have an editable
|
|
document,
|
|
you can invoke the bold command by calling this:<br>
|
|
<div style="margin-left: 40px;"><code>editableDocument.execCommand("Bold",
|
|
false, null); </code></div>
|
|
Notes: If you haven't set designMode to "On", you will get an
|
|
error.
|
|
This could also happen if you call execCommand with the wrong
|
|
document.<br>
|
|
<br>
|
|
There are 3 required parameters for execCommand:<br>
|
|
<ol>
|
|
<li>command string</li>
|
|
<li>boolean flag for showing UI</li>
|
|
<li>value string</li>
|
|
</ol>
|
|
The first parameter is a string which contains the command. The
|
|
second
|
|
parameter is a boolean flag. If it is set to true, you will get
|
|
an
|
|
error (NS_ERROR_NOT_IMPLEMENTED). The third parameter is a string
|
|
which
|
|
is the value. Some commands will require details such as the
|
|
particular
|
|
size you want to set when setting a font size.<br>
|
|
<br>
|
|
The section on Supported Commands will document each command and any
|
|
corresponding values needed.<br>
|
|
</div>
|
|
<div style="margin-left: 40px;"> </div>
|
|
<br>
|
|
<h2>queryCommandEnabled</h2>
|
|
<blockquote>This command operates on the editable document. There
|
|
is
|
|
one required parameter (the command string). The result is a
|
|
boolean
|
|
which is true if the command is can be done given the current selection
|
|
and/or
|
|
caret position. The result is false if the command should not be
|
|
invoked
|
|
(execCommand) given the current selection and/or caret position. <br>
|
|
</blockquote>
|
|
<br>
|
|
<h2>queryCommandState</h2>
|
|
<blockquote>This section needs to be written. It can be called
|
|
similarly to IE implementation.<br>

<h1>Supported Commands:</h1>
|
|
<div style="margin-left: 40px;">The following list of commands is
|
|
presented

|
|
makes
|
|
your code more readable.<br>

toggling the format of generated content. By default (at least

today), this is true. An example of the differences is that the

"bold" command will generate <b> if the useCSS command is false

and generate css style attribute if the useCSS command is true.<br>
