    | 95 | <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>

 | 
  
    | 173 | </form>
 | 
  
    | 174 | 
 | 
  
    | 175 | <h3>Where can I find out more info, download the latest version and talk to
 | 
  
    | 176 | other HTMLArea users?</h3>

    | 203 | <h2>Installation</h2>
 | 
  
    | 204 | 
 | 
  
    | 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
 |

 | 
  
    | 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>

    | 392 | maintainable.  It doesn't even needs comments as it's pretty clear.</p>

    | 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 | 
 |
