Mod de utilizare

1. Copiati codul de mai sus in script-ul JavaScript.
2. Ca sa transformati cod BBCode in HTML, folositi aceasta instructiune:

var html = bbcodeParser.bbcodeToHtml('sir cu BBCode');

3. Ca sa transformati cod HTML in BBCode, folositi aceasta instructiune:

var bbcode = bbcodeParser.htmlToBBCode('sir cu HTML');

- Scriptul poate transforma aceste tag-uri BBCode:

[b]{TEXT}[/b] - {TEXT}
[i]{TEXT}[/i] - {TEXT}
[u]{TEXT}[/u] - {TEXT}
[s]{TEXT}[/s] - {TEXT}
[url={URL}]{TEXT}[/url] - <a href="{URL}" title="link" target="_blank">{TEXT}</a>
[url]{URL}[/url] - <a href="{URL}" title="link" target="_blank">{URL}</a>
[img={URL} width={NUMBER1} height={NUMBER2}]{TEXT}[/img] - <img src="{URL}" width="{NUMBER1}" height="{NUMBER2}" alt="{TEXT}" />
[img]{URL}[/img] - <img src="{URL}" alt="{URL}" />
[color=COLOR]{TEXT}[/color] - {TEXT}
[highlight={COLOR}]{TEXT}[/highlight] - {TEXT}
[quote="{TEXT1}"]{TEXT2}[/quote] - <div class="quote"><cite>{TEXT1}</cite>{TEXT2}</div>
[quote]{TEXT}[/quote] - <cite>{TEXT}</cite>
[blockquote]{TEXT}[/blockquote] - <blockquote>{TEXT}</blockquote>

- Se pot adauga si alte tag-uri BBCode, cu aceasta sintaxa:

bbcodeParser.addBBCode('format bbcode', 'format html');

• Exemplu adaugare tag-uri BBCode:

<script>
/* Aici vine codul obiectului de transformare BBCode-HTML */

// adauga BBCode pt <header> si <div> cu ID
bbcodeParser.addBBCode('[header]{TEXT}[/header]', '<header>{TEXT}</header>');
bbcodeParser.addBBCode('[div id="{IDENTIFIER}"]{TEXT}[/div]', '<div id="{IDENTIFIER}">{TEXT2}</div>');
</script>

- Acest script transforma un sir cu BBCode in HTML, si alt sir cu HTML in BBCode, apoi afiseaza doua ferestre alert cu sirurile transformate.
