<h2>Introduction</h2>
|
| 96 |
|
|
| 97 |
|
<h3>What is HTMLArea?</h3>
|
| 98 |
|
|
| 99 |
|
<p>HTMLArea is a free <acronym title="What You See Is What You Get"
|
| 100 |
|
>WYSIWYG</acronym> editor replacement for <code><textarea></code>
|
| 101 |
|
fields. By adding a few simple lines of JavaScript code to your web page
|
| 102 |
|
you can replace a regular textarea with a rich text editor that lets your
|
| 103 |
|
users do the following:</p>
|
| 104 |
|
|
| 105 |
|
<ul>
|
| 106 |
|
<li>Format text to be bold, italicized, or underlined.</li>
|
| 107 |
|
<li>Change the face, size, style and color.</li>
|
| 108 |
|
<li>Left, center, or right-justify paragraphs.</li>
|
| 109 |
|
<li>Make bulleted or numbered lists.</li>
|
| 110 |
|
<li>Indent or un-indent paragraphs.</li>
|
| 111 |
|
<li>Insert a horizontal line.</li>
|
| 112 |
|
<li>Insert hyperlinks and images.</li>
|
| 113 |
|
<li>View the raw HTML source of what they're editing.</li>
|
| 114 |
|
<li>and much more...</li>
|
| 115 |
|
</ul>
|
| 116 |
|
|
| 117 |
|
<p>Some of the interesting features of HTMLArea that set's it apart from
|
| 118 |
|
other web based WYSIWYG editors are as follows:</p>
|
| 119 |
|
|
| 120 |
|
<ul>
|
| 121 |
|
<li>It's lightweight, fast loading and can transform a regular textarea
|
| 122 |
|
into a rich-text editor with a single line of JavaScript.</li>
|
| 123 |
|
<li>Generates clean, valid HTML.</li>
|
| 124 |
|
<li>It degrades gracefully to older or non-supported browsers
|
| 125 |
|
(they get the original textarea field).</li>
|
| 126 |
|
<li>It's free and can be incorporated into any free or commercial
|
| 127 |
|
program.</li>
|
| 128 |
|
<li>It works with any server-side languages (ASP, PHP, Perl, Java,
|
| 129 |
|
etc).</li>
|
| 130 |
|
<li>It's written in JavaScript and can be easily viewed, modified or
|
| 131 |
|
extended.</li>
|
| 132 |
|
<li>It remembers entered content when a user navigates away and then hits
|
| 133 |
|
"back" in their browser.</li>
|
| 134 |
|
<li>Since it replaces existing textareas it doesn't require a lot of code
|
| 135 |
|
to add it to your pages (just one line).</li>
|
| 136 |
|
<li>Did we mention it was free? ;-)</li>
|
| 137 |
|
</ul>
|
| 138 |
|
|
| 139 |
|
<h3>Is it really free? What's the catch?</h3>
|
| 140 |
|
|
| 141 |
|
<p>Yes! It's really free. You can use it, modify it, distribute it with your
|
| 142 |
|
software, or do just about anything you like with it.</p>
|
| 143 |
|
|
| 144 |
|
<h3>What are the browser requirements?</h3>
|
| 145 |
|
|
| 146 |
|
<p>HTMLArea requires <span class="browser"><a
|
| 147 |
|
href="http://www.microsoft.com/ie">Internet Explorer</a> >= 5.5</span>
|
| 148 |
|
(Windows only), or <span class="browser"><a
|
| 149 |
|
href="http://mozilla.org">Mozilla</a> >= 1.3-Beta</span> on any platform.
|
| 150 |
|
Any browser based on <a href="http://mozilla.org/newlayout">Gecko</a> will
|
| 151 |
|
also work, provided that Gecko version is at least the one included in
|
| 152 |
|
Mozilla-1.3-Beta (for example, <a
|
| 153 |
|
href="http://galeon.sf.net">Galeon-1.2.8</a>). However, it degrades
|
| 154 |
|
gracefully to other browsers. They will get a regular textarea field
|
| 155 |
|
instead of a WYSIWYG editor.</p>
|
| 156 |
|
|
| 157 |
|
<h3>Can I see an example of what it looks like?</h3>
|
| 158 |
|
|
| 159 |
|
<p>Just make sure you're using one of the browsers mentioned above and see
|
| 160 |
|
below.</p>
|
| 161 |
|
|
| 162 |
|
<form onsubmit="return false;">
|
| 163 |
|
<textarea id="TA" style="width: 100%; height: 15em;">
|
| 164 |
|
<p>Here is some sample text in textarea that's been transformed with <font
|
| 165 |
|
color="#0000CC"><b>HTMLArea</b></font>.<br />
|
| 166 |
|
You can make things <b>bold</b>, <i>italic</i>, <u>underline</u>. You can change the
|
| 167 |
|
<font size="3">size</font> and <b><font color="#0000CC">c</font><font color="#00CC00">o</font><font color="#00CCCC">l</font><font color="#CC0000">o</font><font color="#CC00CC">r</font><font color="#CCCC00">s</font><font color="#CCCCCC">!</font></b>
|
| 168 |
|
And lots more...</p>
|
| 169 |
|
|
| 170 |
|
<p align="center"><font size="4" color="#ff0000"><b><u>Try HTMLArea
|
| 171 |
|
today!</u></b></font><br /></p>
|
| 172 |
|
</textarea>
|
| 173 |
|
</form>
|
| 174 |
|
|
| 175 |
|
<h3>Where can I find out more info, download the latest version and talk to
|
| 176 |
|
other HTMLArea users?</h3>
|
| 177 |
|
|
| 178 |
|

|
| 179 |
|

<h2>Keyboard shortcuts</h2>
|
| 186 |

<h2>Installation</h2>
|

|
|
| 205 |
|
<h3>How do I add HTMLArea to my web page?</h3>
|
| 206 |
|
|
| 207 |
|
<p>It's easy. First you need to upload HTMLArea files to your website.
|
| 208 |
|
Just follow these steps.</p>
|
| 209 |
|
|
| 210 |
|
<ol>
|
| 211 |
|
<li>Download the latest version from the <a
|
| 212 |
|
href="http://www.interactivetools.com/products/htmlarea/">htmlArea
|
| 213 |
|
homepage</a>.</li>
|
| 214 |
|
<li>Unzip the files onto your local computer (making sure to maintain the
|
| 215 |
|
directory structure contained in the zip).</li>
|
| 216 |
|
<li>Create a new folder on your website called /htmlarea/ (make sure it's
|
| 217 |
|
NOT inside the cgi-bin).</li>
|
| 218 |
|
<li>Transfer all the HTMLArea files from your local computer into the
|
| 219 |
|
/htmlarea/ folder on your website.</li>
|
| 220 |
|
<li>Open the example page /htmlarea/examples/core.html with your browser to make
|
| 221 |
|
sure everything works.</li>
|
| 222 |
|
</ol>
|
| 223 |
|
|
| 224 |
|
<p>Once htmlArea is on your website all you need to do is add some
|
| 225 |
|
JavaScript to any pages that you want to add WYSIWYG editors to. Here's how
|
| 226 |
|
to do that.</p>
|
| 227 |
|
|
| 228 |
|
<ol>
|
| 229 |
|
|
| 230 |
|
<li>Define some global variables. "_editor_url" has to be the absolute
|
| 231 |
|
URL where HTMLArea resides within your
|
| 232 |
|
website; as we discussed, this would be “/htmlarea/”. "_editor_lang" must
|
| 233 |
|
be the language code in which you want HTMLArea to appear. This defaults
|
| 234 |
|
to "en" (English); for a list of supported languages, please look into
|
| 235 |
|
the "lang" subdirectory in the distribution.
|
| 236 |
|
<pre class="code"
|
| 237 |
|
><span class="function-name"><</span><span class="html-tag">script</span> <span class="variable-name">type=</span><span class="string">"text/javascript"</span><span class="function-name">></span>
|
| 238 |
|
_editor_url = <span class="string">"/htmlarea/"</span>;
|
| 239 |
|
_editor_lang = <span class="string">"en"</span>;
|
| 240 |
|
<span class="function-name"><</span><span class="html-tag">/script</span><span class="function-name">></span></pre>
|
| 241 |
|
|
| 242 |
|
<li>Include the "htmlarea.js" script:
|
| 243 |
|
<pre class="code"
|
| 244 |
|
><span class="function-name"><</span><span class="html-tag">script</span> <span class="variable-name">type=</span><span class="string">"text/javascript"</span> <span class="variable-name">src=</span><span class="string">"/htmlarea/htmlarea.js"</span><span class="function-name">></span><span class="paren-face-match"><</span><span class="html-tag">/script</span><span class="paren-face-match">></span></pre>
|
| 245 |
|
</li>
|
| 246 |
|
|
| 247 |
|
<li><p>If you want to change all your <textarea>-s into
|
| 248 |
|
HTMLArea-s then you can use the simplest way to create HTMLArea:</p>
|
| 249 |
|
<pre class="code"
|
| 250 |
|
><span class="function-name"><</span><span class="html-tag">script</span> <span class="variable-name">type=</span><span class="string">"text/javascript"</span> <span class="variable-name">defer=</span><span class="string">"1"</span><span class="function-name">></span>
|
| 251 |
|
HTMLArea.replaceAll<span class="function-name">()</span>;
|
| 252 |
|
<span class="paren-face-match"><</span><span class="html-tag">/script</span><span class="paren-face-match">></span></pre>
|
| 253 |
|
<p><span class="note">Note:</span> you can also add the
|
| 254 |
|
<code>HTMLArea.replaceAll()</code> code to the <code>onload</code>
|
| 255 |
|
event handler for the <code>body</code> element, if you find it more appropriate.</p>
|
| 256 |
|
|
| 257 |
|
<p>A different approach, if you have more than one textarea and only want
|
| 258 |
|
to change one of them, is to use <code>HTMLArea.replace("id")</code> --
|
| 259 |
|
pass the <code>id</code> of your textarea. Do not use the
|
| 260 |
|
<code>name</code> attribute anymore, it's not a standard solution!</p>
|
| 261 |
|
|
| 262 |
|
</ol>
|
| 263 |
|
|
| 264 |
|
<p>This section applies to HTMLArea-3.0 release candidate 1 or later; prior
|
| 265 |
|
to this version, one needed to include more files; however, now HTMLArea is
|
| 266 |
|
able to include other files too (such as stylesheet, language definition
|
| 267 |
|
file, etc.) so you only need to define the editor path and load
|
| 268 |
|
"htmlarea.js". Nice, eh? ;-)</p>
|
| 269 |
|
|
| 270 |
|
<h3>I want to change the editor settings, how do I do that?</h3>
|
| 271 |
|
|
| 272 |
|
<p>While it's true that all you need is one line of JavaScript to create an
|
| 273 |
|
htmlArea WYSIWYG editor, you can also specify more config settings in the
|
| 274 |
|
code to control how the editor works and looks. Here's an example of some of
|
| 275 |
|
the available settings:</p>
|
| 276 |
|
|
| 277 |
|
<pre class="code"
|
| 278 |
|
><span class="keyword">var</span> <span class="variable-name">config</span> = <span class="keyword">new</span> HTMLArea.Config(); <span class="comment">// create a new configuration object
|
| 279 |
|
</span> <span class="comment">// having all the default values
|
| 280 |
|
</span>config.width = '<span class="string">90%</span>';
|
| 281 |
|
config.height = '<span class="string">200px</span>';
|
| 282 |
|
|
| 283 |
|
<span class="comment">// the following sets a style for the page body (black text on yellow page)
|
| 284 |
|
// and makes all paragraphs be bold by default
|
| 285 |
|
</span>config.pageStyle =
|
| 286 |
|
'<span class="string">body { background-color: yellow; color: black; font-family: verdana,sans-serif } </span>' +
|
| 287 |
|
'<span class="string">p { font-width: bold; } </span>';
|
| 288 |
|
|
| 289 |
|
<span class="comment">// the following replaces the textarea with the given id with a new
|
| 290 |
|
// HTMLArea object having the specified configuration
|
| 291 |
|
</span>HTMLArea.replace('<span class="string">id</span>', config);</pre>
|
| 292 |
|
|
| 293 |
|
<p><span class="warning">Important:</span> It's recommended that you add
|
| 294 |
|
custom features and configuration to a separate file. This will ensure you
|
| 295 |
|
that when we release a new official version of HTMLArea you'll have less
|
| 296 |
|
trouble upgrading it.</p>
|
| 297 |
|
|
| 298 |
|
<h3>How do I customize the toolbar?</h3>
|
| 299 |
|
|
| 300 |
|
<p>Using the configuration object introduced above allows you to completely
|
| 301 |
|
control what the toolbar contains. Following is an example of a one-line,
|

|

<p>The toolbar is an Array of Array objects. Each array in the toolbar
|
| 315 |

defines a new line. The default toolbar looks like this:</p>

|

|
<p>Except three strings, all others in the examples above need to be defined
|
| 334 |
|
in the <code>config.btnList</code> object (detailed a bit later in this
|
| 335 |
|
document). The three exceptions are: 'space', 'separator' and 'linebreak'.
|
| 336 |
|
These three have the following meaning, and need not be present in
|
| 337 |
|
<code>btnList</code>:</p>
|
| 338 |
|
|
| 339 |
|
<ul>
|
| 340 |
|
<li>'space' -- Inserts a space of 5 pixels (the width is configurable by external
|
| 341 |
|
<acronym title="Cascading Style Sheets">CSS</acronym>) at the current
|
| 342 |
|
position in the toolbar.</li>
|
| 343 |
|
<li>'separator' -- Inserts a small vertical separator, for visually grouping related
|
| 344 |
|
buttons.</li>
|
| 345 |
|
<li>'linebreak' -- Starts a new line in the toolbar. Subsequent controls will be
|
| 346 |
|
inserted on the new line.</li>
|
| 347 |
|
</ul>
|
| 348 |
|
|
| 349 |
|
<p><span class="warning">Important:</span> It's recommended that you add
|
| 350 |
|
custom features and configuration to a separate file. This will ensure you
|
| 351 |
|
that when we release a new official version of HTMLArea you'll have less
|
| 352 |
|
trouble upgrading it.</p>
|
| 353 |
|
|
| 354 |
|
<h3>How do I create custom buttons?</h3>
|
| 355 |
|
|
| 356 |
|
<p>By design, the toolbar is easily extensible. For adding a custom button
|
| 357 |
|
one needs to follow two steps.</p>
|
| 358 |
|
|
| 359 |
|
<h4 id="regbtn">1. Register the button in <code>config.btnList</code>.</h4>
|
| 360 |
|
|
| 361 |
|
<p>For each button in the toolbar, HTMLArea needs to know the following
|
| 362 |
|
information:</p>
|
| 363 |
|
<ul>
|
| 364 |
|
<li>a name for it (we call it the ID of the button);</li>
|
| 365 |
|
<li>the path to an image to be displayed in the toolbar;</li>
|
| 366 |
|
<li>a tooltip for it;</li>
|
| 367 |
|
<li>whether the button is enabled or not in text mode;</li>
|
| 368 |
|
<li>what to do when the button is clicked;</li>
|
| 369 |
|
</ul>
|
| 370 |
|
<p>You need to provide all this information for registering a new button
|
| 371 |
|
too. The button ID can be any string identifier and it's used when
|
| 372 |
|
defining the toolbar, as you saw above. We recommend starting
|
| 373 |
|
it with "my-" so that it won't clash with the standard ID-s (those from
|
| 374 |
|
the default toolbar).</p>
|
| 375 |
|
|
| 376 |
|
<p class="note">Register button example #1</p>
|
| 377 |
|
|
| 378 |
|
<pre class="code"
|
| 379 |
|
><span class="comment">// get a default configuration
|
| 380 |
|
</span><span class="keyword">var</span> <span class="variable-name">config</span> = <span class="keyword">new</span> HTMLArea.Config();

| 381 |
|

|
| 382 |
|
// parameters: button ID, tooltip, image, textMode,

| 383 |
|
</span>config.registerButton("<span class="string">my-hilite</span>", "<span class="string">Highlight text</span>", "<span class="string">my-hilite.gif</span>", <span class="keyword">false</span>,

| 384 |
|
<span class="comment">// function that gets called when the button is clicked
|
| 385 |
|
</span> <span class="keyword">function</span>(editor, id) {

|
| 387 |
|
}
|
| 388 |
|
);</pre>
|
| 389 |
|
|
| 390 |
|
<p>An alternate way of calling registerButton is exemplified above. Though
|
| 391 |
|
the code might be a little bit larger, using this form makes your code more
|
| 392 |
|
maintainable. It doesn't even needs comments as it's pretty clear.</p>
|
| 393 |
|
|
| 394 |
|
<p class="note">Register button example #2</p>
|
| 395 |
|
|
| 396 |
|
<pre class="code"
|
| 397 |
|
><span class="keyword">var</span> <span class="variable-name">config</span> = <span class="keyword">new</span> HTMLArea.Config();
|
| 398 |
|
config.registerButton({
|
| 399 |
|
id : "<span class="string">my-hilite</span>",
|
| 400 |
|
tooltip : "<span class="string">Highlight text</span>",
|

|

|
| 402 |
|
textMode : <span class="keyword">false</span>,
|
| 403 |
|
action : <span class="keyword">function</span>(editor, id) {
|
| 404 |
|
editor.surroundHTML('<span class="string"><span class="hilite"></span>', '<span class="string"></span></span>');
|
| 405 |
|
}
|
| 406 |
|
});</pre>
|
| 407 |
|
|
| 408 |
|
<p>You might notice that the "action" function receives two parameters:
|
| 409 |
|
<b>editor</b> and <b>id</b>. In the examples above we only used the
|
| 410 |
|
<b>editor</b> parameter. But it could be helpful for you to understand
|
| 411 |
|
both:</p>
|
| 412 |
|
|
| 413 |
|
<ul>
|
| 414 |
|
<li><b>editor</b> is a reference to the HTMLArea object. Since our entire
|
| 415 |
|
code now has an <acronym title="Object Oriented Programming">OOP</acronym>-like
|
| 416 |
|
design, you need to have a reference to
|
| 417 |
|
the editor object in order to do things with it. In previous versions of
|
| 418 |
|
HTMLArea, in order to identify the object an ID was used -- the ID of the
|
| 419 |
|
HTML element. In this version ID-s are no longer necessary.</li>
|
| 420 |
|
|
| 421 |
|
<li><b>id</b> is the button ID. Wondering why is this useful? Well, you
|
| 422 |
|
could use the same handler function (presuming that it's not an anonymous
|
| 423 |
|
function like in the examples above) for more buttons. You can <a
|
| 424 |
|
href="#btnex">see an example</a> a bit later in this document.</li>
|
| 425 |
|
</ul>
|
| 426 |
|
|
| 427 |
|
<h4>2. Inserting it into the toolbar</h4>
|
| 428 |
|
|
| 429 |
|
<p>At this step you need to specify where in the toolbar to insert the
|
| 430 |
|
button, or just create the whole toolbar again as you saw in the previous
|
| 431 |
|
section. You use the button ID, as shown in the examples of customizing the
|
| 432 |
|
toolbar in the previous section.</p>
|
| 433 |
|
|
| 434 |
|
<p>For the sake of completion, following there are another examples.</p>

|
|
| 452 |
|
<p><span class="note">Note:</span> in the example above our new button is

|
between two vertical separators. But this is by no means required. You can

|

<p>Please note that it is by no means necessary to include the following

|
code into the htmlarea.js file. On the contrary, it might not work there.
|
| 467 |
|
The configuration system is designed such that you can always customize the
|
| 468 |
|
editor <em>from outside files</em>, thus keeping the htmlarea.js file
|
| 469 |
|
intact. This will make it easy for you to upgrade your HTMLArea when we
